Item 1.

Business

Overview

LeMaitre Vascular is a global provider of medical devices and implants for the treatment of peripheral vascular disease. We develop, manufacture, and market vascular devices to address the needs of vascular surgeons. Our diversified portfolio of peripheral vascular devices consists of brand name products that are used in arteries and veins outside of the heart and are well known to vascular surgeons, including the Expandable LeMaitre Valvulotome, the Pruitt-Inahara Carotid Shunt, and VascuTape Radiopaque Tape.

We have grown our business by using a three-pronged strategy: building a worldwide direct sales force, acquiring and developing complementary vascular devices, and developing and enhancing our in-house manufacturing competencies. Since 1998 we have completed ten acquisitions and consolidated most of our manufacturing operations into our Burlington, Massachusetts, headquarters.

We estimate that peripheral vascular disease affects more than 20 million people worldwide. We estimate that the annual worldwide market for all peripheral vascular devices is approximately $3 billion and that the annual worldwide market addressed by our 15 product lines approaches $1 billion. The increasing incidence and diagnosis of peripheral vascular disease is driving the growth of the market for peripheral vascular devices. We believe that our strong brands, established sales force, expanding suite of peripheral vascular devices, and broad network of vascular surgeon customers position us to capture an increasing share of this large and growing market.

We have sought to take advantage of the trend towards endovascular techniques that utilize more complex, higher-priced devices by acquiring new product lines. For example, we market aortic stent grafts, which are endovascular implants used to treat aortic aneurysms and dissections, and remote endarterectomy devices, which are primarily used in the minimally invasive treatment of blockages in the major arteries of the leg. Our vascular surgeon customers are increasingly performing minimally invasive endovascular procedures, presenting us with attractive opportunities to sell new devices that address their changing product needs. We believe that the opportunities are largely incremental to the markets for vascular surgery devices, which include niche markets where we have traditionally enjoyed comparable success.

We sell our products primarily through a direct sales force. Our sales force was comprised of 61 field sales representatives in North America, the European Union, and Japan as of December 31, 2009. We also sell our

products through a network of distributors in various countries outside of the United States and Canada. For the year ended December 31, 2009, approximately 92% of our net sales were generated through our direct sales force, and no customer accounted for more than 2% of our net sales.

Corporate Information

We were incorporated in Massachusetts on November 28, 1983, as Vascutech, Inc. On June 16, 1998, we were reincorporated in Delaware, and on April 6, 2001, we changed our name to LeMaitre Vascular, Inc. Our principal executive offices are located at 63 Second Avenue, Burlington, Massachusetts 01803, and our telephone number is (781) 221-2266.

The Peripheral Vascular Device Market

We estimate that peripheral vascular disease affects more than 20 million people worldwide. The disease encompasses a number of conditions in which the arteries or veins that carry blood to or from the legs, arms, or organs other than the heart become narrowed, obstructed, weakened, or otherwise compromised. In many cases peripheral vascular disease goes undetected, sometimes leading to life-threatening events—such as stroke, ruptured aneurysm, or pulmonary embolism—or death.

Clinical studies have identified several factors that increase the risk of peripheral vascular disease, including smoking, diabetes, obesity, high blood pressure, lack of exercise, coronary artery disease, high cholesterol, and being over the age of 65. Demographic trends suggest an increase in the prevalence of peripheral vascular disease over time, driven primarily by rising levels of obesity and diabetes and an aging population.

Vascular surgeons treat peripheral vascular disease and also perform vascular procedures associated with other diseases, such as end-stage renal disease. We estimate that there are more than 2,000 board-certified vascular surgeons and several thousand general surgeons who perform vascular procedures in the United States, and that there are more than 3,000 vascular surgeons in Europe and Japan. Vascular surgeons perform both conventional vascular surgeries and endovascular procedures. Conventional vascular surgery involves opening the body, cutting vessels, and suturing. Endovascular procedures typically are minimally invasive, catheter-based procedures involving repairing vessels from within using real-time imaging technologies.

We estimate that the worldwide market for peripheral vascular devices is approximately $3 billion. We believe that this market will grow due to the increase in the incidence and diagnosis of peripheral vascular disease, a shift to higher priced endovascular devices, and the adoption of western healthcare standards by the developing world.

Our History

We were founded in 1983 by George D. LeMaitre, M.D., a vascular surgeon who designed and developed the predecessor to our Expandable LeMaitre Valvulotome. Through a combination of strategic acquisition and research and development efforts, we have expanded our catalog to 15 product lines across three product categories.

We have conducted ten acquisitions since 1998:


Year	Acquisition	Key Product Line(s)
1998	Whittaker Screen Printing	Radiopaque tape manufacturing operations
1999	Vermed	Vascular Catheters
2001	Ideas for Medicine	Carotid shunts, vascular catheters, and cholangiogram catheters
2003	Credent	Vascular access grafts
2004	VCS Clip	Anastomotic clips
2005	Endomed	Thoracic and abdominal stent grafts
2007	Vascular Innovations	Contrast injector
2007	Vascular Architects	Remote endarterectomy devices
2007	UnBalloon Technology	Stent graft modeling catheters
2007	Biomateriali	Polyester grafts and patches

Twelve of our 15 product lines were in large part acquired via these acquisitions. We have completed the integration of each of these product lines, consolidating virtually all of the associated manufacturing operations into our Burlington, Massachusetts, headquarters.

Prior to 1999, we had no direct sales force and instead relied on direct marketing to generate brand awareness and product loyalty. In 1999, we began building a direct sales organization that we have continued to expand, most recently into the French and Italian markets. We currently sell products directly to our hospital customers in the United States and Canada, Japan, and most major European markets.

Our Business Strategies

Our goal is to be the leading global provider of medical devices to vascular surgeons.

To achieve this objective, we are utilizing the following long-term strategies:

•

Acquire Complementary Products. We believe our significant experience in acquiring and integrating product lines and businesses is one of our competitive advantages. We actively track industry developments and plan to acquire additional product lines and businesses as a means of further accessing the peripheral vascular device market. We intend to expand and diversify our product offerings and add new technology platforms.

•

Extend Our Market Reach through Research and Development and Additional Regulatory Approvals. By refining our current product lines and developing new applications for our existing technologies, we plan to extend our reach into the peripheral vascular device market. We also intend to obtain regulatory approvals for our devices in new markets. For example, we currently market our aortic stent graft devices in the European Union and have focused our near-term efforts on obtaining regulatory approval for these products in the United States. We are also seeking clearance for the sale of The UnBalloon Non-Occlusive Modeling Cather product line in the United States.

•

Expand Our Direct Sales Force. We sell our products primarily through a direct sales force comprised as of December 31, 2009, of 61 field sales representatives in North America, the European Union, and Japan. As a long-term strategy, we intend to further expand our sales force. We believe that direct-to-hospital sales engender closer customer relationships, allow for higher selling prices and gross margins, and are not subject to the risk of customer churn resulting from distributor turnover.

The Flexcel Carotid Shunt is available for sale in the United States and the European Union, but is not yet available for sale in Japan. We have submitted an application for Shonin registration of the Flexcel Carotid Shunt with the Japan Ministry of Health, Labor and Welfare.

We also distribute the Powerlink System—a bifurcated abdominal stent graft manufactured by Endologix, Inc.—in several European countries, including Germany, France, and the United Kingdom. We believe that this product complements our TAArget Thoracic Stent Graft and UniFit Abdominal Stent Graft product lines, allowing our growing European sales force to offer a complete range of stent grafts for the entire aorta.

Additionally, we engage in a limited amount of private label manufacturing.

Endovascular

Our endovascular products are used primarily by vascular surgeons in minimally invasive endovascular procedures, such as stent-grafting, angioplasty, stenting, and atherectomy.

TAArget Thoracic Stent Graft

The TAArget Thoracic Stent Graft is an endovascular graft used to treat an aortic aneurysm, a weakening and ballooning of the aorta, or an aortic dissection, a separation of the layers of the aortic wall that often leads to rupture and death, in each case in the upper part of the aorta, known as the thoracic aorta. The TAArget Thoracic Stent Graft features our TT Tortuous Tracker Delivery System. TAArget’s flexible, encapsulated design uses

expanded polytetrafluoroethylene (ePTFE), which is designed to prevent the stent scaffolding from contacting either the blood stream or the vessel wall. This design also allows us to offer a wide range of stent grafts sizes, including tapered grafts, which fit a wider range of patient anatomies than many of our competitors’ products. Our TAArget Thoracic Stent Graft product line is currently sold in the European Union and a small number of foreign jurisdictions. We are currently conducting a feasibility study in the United States for the TAArget device. See “—Clinical Studies” for a description of this clinical study.

The UnBalloon Non-Occlusive Modeling Catheter

The UnBalloon Non-Occlusive Modeling Catheter is used to apply radial pressure to the inside of an aortic stent graft in order to seal the outer lining of the stent graft against the interior wall of the aorta. The physician expands the device’s nitinol mesh cage inside of the stent graft in order to appose the stent graft lining against the vessel wall. An adequate seal will exclude blood flow from the aneurysm, thereby preventing an endoleak, a condition in which blood continues to enter the aneurismal sac, increasing the risk of aneurysm rupture and death. Unlike a balloon catheter, The UnBalloon catheter dilates the aortic stent graft without occluding blood flow, allowing the physician more time to repair an endoleak or model the stent graft while minimizing the risk of stent graft migration. The UnBalloon Non-Occlusive Modeling Catheter product line is currently sold in the European Union. We have submitted an application for 510(k) clearance of The UnBalloon Non-Occlusive Modeling Catheter with the U.S Food and Drug Administration (the FDA).

UniFit Abdominal Stent Graft

The UniFit Abdominal Stent Graft is a non-bifurcated endovascular graft used to treat aneurysms in the lower part of the aorta, known as the abdominal aorta, and the iliac arteries. The UniFit device is similar in design to the TAArget device, with a flexible, encapsulated design and similar manufacturing advantages that allow us to offer a wide range of stent graft sizes and custom-built devices. The UniFit Abdominal Stent Graft is also available with the TT Tortuous Tracker Delivery System. This product line is currently sold in the European Union and a small number of foreign jurisdictions. We are currently conducting a pivotal study in the United States for the UniFit device. See “—Clinical Studies” for a description of this clinical study.

VascuTape Radiopaque Tape

VascuTape Radiopaque Tape is a flexible, medical-grade tape with centimeter or millimeter markings printed in our proprietary radiopaque ink that is visible both to the eye and to an x-ray machine or fluoroscope. VascuTape Radiopaque Tape is applied to the skin and provides interventionalists with a simple way to cross-reference precisely between the inside and the outside of a patient’s body, allowing them to accurately size or locate tributaries or lesions beneath the skin. VascuTape Radiopaque Tape enables smaller skin incisions, more accurate lesion location, more precise stent and catheter sizing, and reduced contrast injections. Our VascuTape product line is currently sold in the United States, the European Union, Japan, and many other foreign jurisdictions.

Vascular Products

Our vascular products are used primarily in open vascular surgery for the treatment of peripheral vascular disease.

AlboSure and XenoSure Vascular Patches

Vascular surgeons use patches in conjunction with carotid endarterectomy, remote endarterectomy, and other vascular reconstructions. We recently received regulatory approval to market our AlboSure Vascular Patch in the European Union. The AlboSure Vascular Patch is a polyester patch used in conjunction with endarterectomy and vascular reconstructions. We intend to begin selling this device in the European Union in

2010. We also distribute the XenoSure Biologic Vascular Patch, a patch made from bovine pericardium. The patch is exceptionally strong, uniform and easy to handle and suture We have rights to distribute this product under our “XenoSure” brand in the United States and most of Europe until January 26, 2016, and an option to acquire this product commencing January 2, 2014 and expiring January 26, 2016. We currently sell this product in the United States. Neovasc is actively seeking approval for us to sell this product in the European Union.

AlboGraft Vascular Graft

The AlboGraft Vascular Graft is a collagen-coated polyester graft used to bypass or replace diseased arteries. Available in both straight tube and bifurcated versions, the AlboGraft Vascular Graft offers excellent feel and ease of manipulation to our surgeon customers, while the collagen coating provides immediate sealing of suture holes. These knitted and woven vascular grafts are an essential part of the vascular surgeon’s toolkit and complement LeMaitre Vascular’s other product lines. Our AlboGraft Vascular Graft product line is currently sold in the United States, the European Union and many other foreign jurisdictions.

We acquired the AlboGraft Vascular Graft product line through our acquisition of Biomateriali S.r.l. in December 2007. Until recently, this product line was sold through an exclusive distribution agreement with Edwards Lifesciences AG. In March 2009, we paid $3.5 million to Edward Lifesciences in exchange for the early termination of this distribution agreement, the purchase of their AlboGraft customer list and certain customer contracts, and their provision of sales and marketing services. We also repurchased most of Edwards’ remaining AlboGraft inventory. We commenced direct-to-hospital sales in Europe in March 2009 and introduced the device in the United States in March 2010.

AnastoClip and AnastoClip GC Vessel Closure Systems

The AnastoClip Vessel Closure System is a titanium clip implanted by vascular surgeons to attach vessels, native and prosthetic, to each other. The AnastoClip Vessel Closure System creates an interrupted anastomosis, or a vessel attachment that expands and contracts as the vessel pulses, which we believe improves the durability of the anastomosis. A retrospective 1,110-patient clinical study published in the August 2003 Journal of Vascular Surgery found that the AnastoClip Vessel Closure System improved 24-month patency versus traditional continuous sutures from approximately 34% to 54% in arterio-venous fistulae, which are surgical attachments of arteries and veins, and from approximately 17% to 36% in prosthetic grafts attachments. Patency data was collected from a total of 1,385 vascular access anastomoses. Our AnastoClip Vessel Closure System product line is currently sold in the United States, the European Union, Japan, and many other foreign jurisdictions.

In the European Union, we recently began a limited market release of next-generation version called the AnastoClip GC Vessel Closure System with a new clip design that is intended to provide additional security and ease of use. We intend to submit an application for 510(k) clearance of the AnastoClip GC Vessel Closure System with the FDA.

EndoRE Remote Endarterectomy Devices

The EndoRE line of remote endarterectomy devices are used to remove severe atherosclerotic blockages from the major arteries of the leg in a minimally invasive procedure requiring a single incision in the groin. Our EndoRE devices are used to separate the sclerotic blockage from the vessel, cut the far end of the blockage to free it for removal, and then withdraw the blockage from the vessel. A retrospective 133-patient clinical study published in the February 2006 Journal of Vascular Surgery found that, compared to bypass procedures, this minimally invasive procedure leads to less trauma to the patient and reduced hospital stays. It also preserves the patient’s own veins for future use in an unrelated bypass procedure. Our EndoRE Remote Endarterectomy Devices are currently sold in the United States and Europe.

Expandable LeMaitre Valvulotome

The Expandable LeMaitre Valvulotome cuts valves in the saphenous vein, a vein that runs from the ankle to the groin, so that it can function as a bypass vessel to carry blood past diseased arteries to the lower leg or the foot. The Expandable LeMaitre Valvulotome is the only self-sizing and self-centering valvulotome available. We believe that the Expandable LeMaitre Valvulotome reduces costs for hospitals by enabling less invasive bypass surgery to be performed with several one-inch incisions rather than one continuous ankle-to-groin incision, thereby reducing the length of hospital stays and the likelihood of wound complications. The Expandable LeMaitre Valvulotome is the sixth generation of the original valvulotome developed by our founder, George D. LeMaitre, M.D. Our Expandable LeMaitre Valvulotome product line is currently sold in the United States, the European Union, Japan, and many other foreign jurisdictions.

LeMaitre Vascular Catheters for Embolectomy, Occlusion and Perfusion

Embolectomy catheters are used to remove blood clots from arteries or veins. We manufacture single-lumen latex and latex-free embolectomy catheters as well as dual-lumen latex embolectomy catheters. The dual-lumen embolectomy catheter allows clot removal and simultaneous irrigation or guide-wire trackability. Occlusion catheters temporarily occlude blood flow to allow the vascular surgeon time and space to complete a given procedure. Perfusion catheters temporarily perfuse blood and other liquids into the vasculature. Our Pruitt Occlusion and Perfusion Catheters reduce vessel trauma by using internal balloon fixation rather than traditional external clamp fixation. Our embolectomy, occlusion, and perfusion catheters are currently sold in the United States, the European Union, Japan, and many other foreign jurisdictions.

Pruitt-Inahara, Pruitt F3, and Flexcel Carotid Shunts

The Pruitt-Inahara, Pruitt F3, and Flexcel Carotid Shunts are used to temporarily divert, or shunt, blood to the brain while the surgeon removes plaque from the carotid artery in a carotid endarterectomy surgery. Our Pruitt-Inahara and Pruitt F3 shunts feature internal balloon fixation that eliminates the need for clamps, thereby reducing vessel trauma. Our Flexcel shunt is a non-balloon shunt offered for surgeons who prefer to secure their shunt using the traditional method of externally placed clamps. Our Pruitt-Inahara Carotid Shunts are currently sold in the United States, the European Union, Japan, and many other foreign jurisdictions. The Pruitt F3 Carotid Shunt is only available for sale in the United States. The Flexcel Carotid Shunt is available for sale in the United States the European Union, and many other foreign jurisdictions, but is not yet available for sale in Japan.

General Surgery Products

Our general surgery products are used primarily by general surgeons in non-vascular procedures. Our primary general surgery product is the Reddick Cholangiogram Catheter, which is used to inject dye into the cystic duct during a laparoscopic cholecystectomy. In this procedure, the gall bladder is dissected and removed through small punctures in the abdomen. We also offer two laparoscopic accessories used in laparoscopic gall bladder removal, as well as an implantable port used in the intravascular delivery of fluid, medications, and nutritionals. These products are currently sold in the United States, the European Union, and many other foreign jurisdictions.

Clinical Studies

We conduct clinical studies in order to obtain regulatory approval and provide marketing data for our product lines. The goal of a clinical study is to evaluate the safety and/or clinical effectiveness of a device or the substantial equivalence to another device. We currently have two active U.S. clinical studies:

•

UniFit Abdominal Stent Graft. We are conducting a U.S. pivotal study of our UniFit Abdominal Stent Graft called the UNITE Trial. The UNITE Trial is intended to evaluate the safety and effectiveness of the UniFit Abdominal Stent Graft in the treatment of aorto, aorto-iliac, and/or iliac aneurysms as

compared against that of a previously approved device, and is intended to be the principal basis for premarket application (PMA) approval. In May 2007, we received approval from the FDA to commence the UNITE trial. We plan to enroll 90 patients at up to 22 institutions. As of March 25, 2010, we had enrolled 54 patients in the trial. The primary effectiveness endpoint of the study is based on aneurysm exclusion as evaluated through one-year follow-up.

•

TAArget Thoracic Stent Graft. We have begun preparations for a U.S. feasibility study of our TAArget Thoracic Stent Graft called the ENTRUST Trial. A feasibility study is a preliminary study and is not a pivotal trial. The ENTRUST Trial is intended to evaluate the safety and efficacy of the TAArget Thoracic Stent Graft in the treatment of aneurysms in the descending thoracic aorta as compared against that of open surgical thoracic aorta repair. We plan to enroll 30 patients at up to five centers. These patients must be followed for at least six months prior to our application to the FDA to conduct a pivotal study in support of a potential PMA approval. The primary effectiveness endpoint of the study is based on endoleak occurrence, aneurysm size change, device migration, aneurysm exclusion, and aneurysm rupture as evaluated through six-month follow-up. The primary safety endpoint of the study is based on major adverse event occurrence as evaluated through six-month follow-up.

In May 2008, we submitted an investigational device exemption (IDE) application to the FDA to begin the ENTRUST Trial. Because the TAArget Thoracic Stent Graft is a “significant risk” device for regulatory purposes, the FDA must approve the IDE application prior to the start of the ENTRUST Trial. On December 4, 2009, we received conditional approval from the FDA to commence the ENTRUST Trial, provided that we resolve the issues identified in the conditional approval letter to the FDA’s satisfaction. We intend to work with the FDA to resolve these issues, although there can be no assurance that the FDA will unconditionally approve the IDE application.

Clinical studies are subject to a number of factors that can influence results, making it difficult to draw general conclusions. Peripheral vascular studies have historically involved very few patients, with even fewer patients available for long-term follow up and analysis. Among a small number of treated patients, these factors can influence the significance of clinical study results. Consequently, findings from one study should not be used to predict limitations or benefits of a particular means of treatment. We continually evaluate the potential financial benefits and costs of our clinical studies and the products being evaluated in them. If we determine that the costs associated with obtaining regulatory approval of a product exceed the potential financial benefits of that product or if the projected development timeline is inconsistent with our investment horizon, we may choose to stop a clinical study and/or the development of a product. See “Risk Factors—If we are not successful in obtaining and maintaining clearances and approvals from governmental agencies, we will not be able to sell our products, and our future growth will be significantly hampered.” If these clinical studies are unsuccessful, or if the FDA or other regulatory agencies do not accept or approve the results of such studies, these products may not successfully come to market and our business prospects may suffer.

Sales and Marketing

As of December 31, 2009, we employed 61 field sales representatives. We believe that the expansion of our direct sales force has been a key factor in our success and it remains one of our primary long-term strategies. As a long-term strategy, we intend to further expand our sales force. Outside our direct markets, we generally sell our products through a network of country-specific distributors. We typically sign exclusive distribution agreements with terms of up to five years specifying minimum annual sales volumes and pricing. These agreements are only renewable by mutual agreement. As exceptions to our direct sales and country-specific distribution models, we sell unbranded polyester vascular graft components under a private label manufacturing program.

In addition, we engage in direct marketing efforts, which we believe are critical to our brand development and continued success. We believe that direct marketing allows us to market to vascular surgeons beyond the reach of our direct sales force.

Research and Development

Our research and development has historically focused on developing enhancements and extensions to our existing product lines. Our current product development efforts are largely focused on the endovascular space, including improvements to our TAArget and UniFit Stent Grafts. In recent years we have increased investment in product research and development, with the goal of more rapidly developing new products, line extensions, and next-generation devices in our endovascular and vascular product categories.

Our products are subject to our design control procedures throughout the various stages of product development. These procedures may include bench testing, animal testing, human use testing conducted by independent physicians, and post-market surveillance of product performance, as appropriate. We may use feedback received from independent physicians to demonstrate product functionality, safety, and effectiveness before commencing full-scale marketing of any product.

For fiscal 2007, 2008, and 2009, our research and development expenditures, including clinical study expenditures, were $4.6 million, $5.3 million and $5.9 million, respectively, and represented between 11% and 12% of net sales. As of December 31, 2009, our research and development staff consisted of 15 full-time engineers and technicians.

Manufacturing

Our manufacturing facilities are located in Burlington, Massachusetts, where most of our product lines are produced in a 5,556 square foot ISO 14644-1 Class 8 clean room, and in Brindisi, Italy, where we produce our AlboGraft Vascular Graft and AlboSure Vascular Patch product lines and perform select other manufacturing processes in a 7,535 square foot ISO 14644-1 Class 8 clean room. In addition, with our acquisition of the business of Vascular Architects in September 2007, we inherited certain third-party manufacturing relationships relating to the production of each of the EndoRE Remote Endarterectomy Devices.

We manufacture certain proprietary components, assemble most of our devices ourselves, and inspect, test, and package all of our finished products. By designing and manufacturing many of our products from raw materials, and assembling and testing as many of our subassemblies and products as practical, we believe that we can maintain better quality control, ensure compliance with applicable regulatory standards and our internal specifications, limit outside access to our proprietary technology, ensure adequate product supply, and make design modifications in a timely manner. We have custom-designed proprietary manufacturing and processing equipment and have developed proprietary enhancements for existing production machinery.

Nearly all of our products are built to stock. The only exceptions are the aortic stent grafts that we custom build for specific anatomies as requested by physicians. We believe that our custom manufacturing of stent grafts engenders physician loyalty and brand awareness.

Our management information systems provide us with the ability to evaluate our performance, collect business intelligence, and make better strategic decisions. These systems include order entry, invoicing, on-line inventory management, lot traceability, purchasing, shop floor control, and shipping and distribution analysis, as well as various accounting-oriented functions. During day-to-day operations, these systems enable us to track our products from the inception of an order through the manufacturing process and then through delivery of the product to the customer.

We have implemented a variety of manufacturing strategies and techniques with the goal of improving our gross margin and increasing product quality. By instituting lean manufacturing techniques, we have been able to reduce time, space, and materials from several of our production lines, while simultaneously improving quality.

We purchase components from, and have certain product lines manufactured by, third parties. Most of our components are readily available from several supply sources, but we do rely on single- and limited-source suppliers for several of our key product components and our third-party-manufactured products. We do not have contractual arrangements with most of these suppliers and manufacturers, and we order our supplies and product on an as-needed basis. To date, we not experienced any material disruption in the adequate supply from existing sources of product and components.

Any disruption in our manufacturing capacity could impact our ability to produce sufficient inventory and meet the demands of our customers, which could adversely affect our financial condition and results of operations.

Our manufacturing facilities have been certified to ISO 13485:2003 quality management system standards, which enables us to satisfy certain regulatory requirements of the European Union, Canada, and other foreign jurisdictions. If we were to lose these certifications, we would no longer be able to sell our products in these countries until we made the necessary corrections to our operations or, in the case of the European Union, satisfactorily completed an alternate approval route that did not rely on compliance with quality system standards. Our manufacturing facilities are subject to periodic inspections by regulatory authorities and our Notified Body (described below) to ensure compliance with domestic and non-U.S. regulatory requirements. See “—Government Regulation.”

Competition

The markets in which our 15 product lines compete are characterized by rapid change resulting from technological advances and scientific discoveries. No one company competes against us in all of our product lines. Rather, we compete with a range of companies, from large to small, including both publicly traded and privately held device companies. Notable competitors include Applied Medical Resources Corporation, Cardiovascular Systems Inc., Cook Group Incorporated, C.R. Bard, Inc., Edwards Lifesciences Corporation, Getinge AB, Medtronic, Inc., Terumo Medical Corporation, Uresil, LLC, and W. L. Gore & Associates.

Our products compete primarily on the basis of their innovative technology, quality, reliability, ease of use, cost-effectiveness, physician familiarity, brand recognition, and service support. Several of our products are sold at higher prices than those of our competitors. We believe that our continued success will depend on our ability to broaden and optimize our direct sales channel, acquire or develop additional vascular device product lines, obtain patent or other product protections, obtain regulatory and reimbursement approvals, maintain sufficient inventory to meet customer demand, and attract and retain skilled personnel.

Many of our competitors have substantially greater financial, technological, research and development, regulatory, marketing, sales, and personnel resources than we do. Certain of these competitors may also have greater experience in developing products, obtaining regulatory approvals, and manufacturing and marketing such products. Certain of these competitors may obtain patent protection or regulatory approval or clearance, or achieve product commercialization, before us, any of which could materially adversely affect us. We have from time to time experienced difficulties competing against very large companies. For example, we believe that intense competition from Medtronic, W. L. Gore and Cook has affected the adoption of our TAArget Thoracic Stent Graft in European markets

Intellectual Property

We believe that our success is dependent, to a certain extent, on the development and maintenance of proprietary aspects of our technologies. We rely on a combination of patents, trademarks, trade secret laws, and confidentiality and invention assignment agreements to protect our intellectual property rights.

As of December 31, 2009, we actively maintained 29 issued patents and 6 pending patent applications in the United States, Europe, Japan, Australia, Canada, and other countries throughout the world relating to various aspects of our products and/or manufacturing processes. The majority of our issued U.S. patents are set to expire at various times from 2012 to 2020. We do not expect the near-term expiration of any of our issued U.S. patents to adversely affect our intellectual property position.

We intend to file and prosecute patent applications for our technology in jurisdictions where we believe that patent protection is effective and advisable. Generally, for products that we believe are appropriate for patent protection, we will attempt to obtain patents in the United States and key markets of the European Union. However, depending on circumstances, we may not apply for patents in all or any of those jurisdictions, or we may pursue patent protection elsewhere.

Notwithstanding the foregoing, the patent positions of medical device companies, including our company, are uncertain and involve complex and evolving legal and factual questions. The coverage sought in a patent application can be denied or significantly reduced either before or after the patent is issued. Consequently, there can be no assurance that any of our pending patent applications will result in an issued patent. There is also no assurance that any existing or future patent will provide significant protection or commercial advantage, or whether any existing or future patent will be dominated by a more basic patent, thus possibly requiring us to obtain a license to produce and sell the product.

While most of the world relies on a first-to-file system, the U.S. gives patent rights to whomever was the first to invent an idea, even if the inventor filed the related patent application after another was filed covering the same idea. Because patent applications can be maintained in secrecy for at least 18 months after their earliest priority date, and publication of discoveries in the scientific or patent literature often lags behind actual discoveries, we cannot be certain that we were the first to invent the subject matter covered by each of our pending U.S. patent applications or that we were the first to file non-U.S. patent applications for such subject matter. For example, in 2005 and 2006 Boston Scientific Corporation initiated opposition proceedings in the European Patent Office claiming that we were not the first to file a patent application on certain material. As a result of these opposition proceedings, some of our patent claims were canceled. Although the cancellation of these patent claims did not affect our ability to manufacture, distribute, or sell any of our products, it could affect our right to exclude others from selling products similar to our TAArget and UniFit stent grafts in Europe.

Because the U.S. follows a first-to-invent system, if a third party files a patent application relating to an invention claimed in our patents or patent applications, we may be required to participate in an interference proceeding declared by the U.S. Patent and Trademark Office to determine who was the first to invent the idea in question and therefore who should own the patent rights to that idea. Such a proceeding could involve substantial uncertainties and cost, even if the eventual outcome is favorable to us. There can be no assurance that our patents, if issued, would be upheld as valid in court.

Third parties may claim that our products infringe on their patents and other intellectual property rights. Some companies in the medical device industry have used intellectual property infringement litigation to gain a competitive advantage. If a competitor were to challenge our patents, licenses, or other intellectual property rights, or assert that our products infringe its patent or other intellectual property rights, we could incur substantial litigation costs, be forced to make expensive changes to our product designs, license rights in order to continue manufacturing and selling our products, or pay substantial damages. Third-party infringement claims, regardless of their outcome, would not only consume our financial resources but also divert our management’s time and effort. Such claims could also cause our customers or potential customers to defer or limit their purchase or use of the affected products until resolution of the claim.

Certain aspects of our products are covered by patents held by third parties. We manufacture, market, and sell these products pursuant to license agreements with these third parties. These arrangements require us to pay royalties, typically determined as a percentage of our net sales for the underlying product. If we fail to make

these payments or otherwise fail to observe the terms of these agreements, we may lose our ability to sell these products. For example, we manufacture, market, and sell our TAArget and UniFit stent grafts pursuant to a sublicense from Bard Peripheral Vascular, Inc., a subsidiary of C.R. Bard, Inc., to a U.S. patent covering aspects of ePTFE. Our arrangement with Bard may preclude us from assigning the sublicense to a third party, including in connection with the sale of more than 30% of our capital stock or all or substantially all of our assets, without the prior consent of Bard. The loss by us of our right to manufacture, market, and sell our TAArget and UniFit products could adversely affect our business and results of operations, perhaps materially. We also manufacture, market, and sell our AnastoClip and AnstoClip GC Vessel Closure Systems, EndoHelix Retrieval Device, Grice Suture Needle, MollRing Cutter Transection Device, Reddick-Saye Screw, and Periscope Dissector products pursuant to licenses with third-party patent holders.

We believe that our strong brands have been an important factor in our success. We rely on common law and registered trademarks to protect our product brands. Some of our registered trademarks are LeMaitre, Pruitt, VascuTape, Glow ‘N Tell, and Reddick, each of which is registered in the United States and the European Union, and in certain cases in other foreign countries.

We rely on trade secret protection for certain unpatented aspects of other proprietary technology. Some of our products are not protected by patents. In the past, other companies have independently developed or otherwise acquired comparable or substantially equivalent proprietary information and techniques, and there can be no assurance that others will not do so in the future or otherwise gain access to our proprietary technology or disclose such technology, or that we can meaningfully protect our trade secrets. We have a policy of requiring key employees and consultants to execute confidentiality agreements upon the commencement of an employment or consulting relationship with us. Our confidentiality agreements also require our employees to assign to us all rights to any inventions made or conceived during their employment with us. We also generally require our consultants to assign to us any inventions made during the course of their engagement by us. There can be no assurance, however, that these agreements will provide meaningful protection or adequate remedies for us in the event of unauthorized use, transfer, or disclosure of confidential information or inventions.

The laws of foreign countries generally do not protect our proprietary rights to the same extent as do the laws of the United States. In addition, we may experience more difficulty enforcing our proprietary rights in certain foreign jurisdictions.

Government Regulation

The products we manufacture and market are subject to regulation by the FDA, and, in some instances, other federal and state authorities and foreign governments.

United States Regulation

Our products are medical devices subject to extensive regulation by the FDA under the Federal Food, Drug, and Cosmetic Act (the FDCA). FDA regulations govern, among other things, product development, testing, manufacture, packaging, labeling, storage, clearance or approval, advertising and promotion, sales and distribution, and import and export.

Premarket Pathways

Medical devices must receive either 510(k) clearance or premarket application approval (PMA approval) from the FDA prior to commercial distribution. Devices deemed to pose relatively less risk are placed in either class I or II, which requires the manufacturer to submit a premarket notification requesting permission for commercial distribution; this is known as 510(k) clearance. Some low-risk devices are exempted from this requirement. Class II devices may be subject to special controls, such as performance standards and FDA guidelines that are not applied to class I devices. Devices deemed by the FDA to pose the greatest risk, such as

life-sustaining, life-supporting, or implantable devices, or devices deemed not substantially equivalent to a previously 510(k)-cleared device or to a preamendment class III device (i.e., one in commercial distribution before May 28, 1976) for which PMA applications have not been called, are placed in class III, which requires PMA approval. In most cases, a user fee is required for 510(k) submissions and PMA applications, which in the case of PMA applications can be very costly.

510(k) Clearance. To obtain 510(k) clearance, a manufacturer must submit a premarket notification demonstrating that the proposed device is substantially equivalent in intended use and in safety and effectiveness to a “predicate device” (i.e., a previously 510(k)-cleared class I or class II device or a preamendment class III device for which the FDA has not yet called for PMA applications). The FDA’s 510(k) clearance pathway usually takes from three to twelve months, but it can last longer. In reviewing a premarket notification, the FDA may request additional information, including clinical data. For example, in reviewing our premarket notification for the AlboGraft Vascular Graft, the FDA requested, and we submitted, clinical data from the use of the device in other countries where it was then already approved for sale. All of our devices sold in the United States to date are marketed pursuant to the 510(k) process.

After a device receives 510(k) clearance, any modification that could significantly affect its safety or effectiveness, or that would constitute a major change in its intended use, requires a new 510(k) clearance. The FDA requires each manufacturer to make this determination in the first instance, but the FDA can review any such decision. If the FDA disagrees with a manufacturer’s decision not to seek a new 510(k) clearance, the agency may retroactively require the manufacturer to seek 510(k) clearance. The FDA also can require the manufacturer to cease marketing and/or recall the modified device until 510(k) clearance or PMA approval is obtained. Also, the manufacturer may be subject to significant regulatory fines or penalties.

PMA Approval. The PMA approval pathway requires proof of the safety and effectiveness of the proposed device to the FDA’s satisfaction, making this pathway much more costly, lengthy, and uncertain. A PMA application must provide extensive preclinical and clinical trial data, as well as detailed information about the device and its components regarding, among other things, device design, manufacturing, and labeling. As part of the PMA review, the FDA will typically inspect the manufacturer’s facilities for compliance with the Quality System Regulation, or QSR, which imposes elaborate testing, control, documentation, and other quality assurance procedures on the manufacturing process.

If the FDA approves a PMA, the approved indications or claims may be more limited than those originally sought. The PMA can include post-approval conditions that the FDA believes to be necessary to ensure the safety and effectiveness of the device including, among other things, restrictions on labeling, promotion, sale, and distribution. Failure to comply with the conditions of approval can result in material adverse enforcement action, including the loss or withdrawal of the approval. Even after approval of a PMA, a new PMA or PMA supplement is required if the device or its labeling or manufacturing process are modified. Supplements to a PMA often require the submission of the same type of information required for an original PMA, except that the supplement is generally limited to that information needed to support the proposed change from the product covered by the original PMA.

Clinical Trials. A clinical trial is typically required to support a PMA application and is sometimes required to support 510(k) clearance. In some cases, one or more smaller feasibility IDE studies may precede a pivotal IDE clinical trial intended to comprehensively demonstrate the safety and effectiveness of the investigational device. All clinical studies of investigational devices must be conducted in compliance with the FDA’s extensive requirements. If an investigational device could pose a significant risk to patients (as defined in the regulations), the FDA, prior to initiation of clinical use, must approve an IDE application showing that it is safe to test the device in humans and that the testing protocol is scientifically sound. A non-significant risk device does not require submission to the FDA of an IDE application. Both significant risk and non-significant risk investigational devices require approval from institutional review boards, or IRBs, at the study centers where the

device will be used. The FDA and the IRB at each institution at which a clinical trial is being performed may suspend a clinical trial at any time for various reasons, including a belief that the subjects are being exposed to an unacceptable health risk.

In May 2008, we submitted an investigational device exemption (IDE) application to the FDA to begin our ENTRUST Trial. Because the TAArget Thoracic Stent Graft is a “significant risk” device for regulatory purposes, the FDA must approve the IDE application prior to the start of the ENTRUST Trial. On December 4, 2009, we received conditional approval from the FDA to commence the ENTRUST Trial, provided that we resolve the issues identified in the conditional approval letter to the FDA’s satisfaction. We intend to work with the FDA to resolve these issues, although there can be no assurance that the FDA will unconditionally approve the IDE application.

During a study, the sponsor must comply with the FDA’s IDE requirements for investigator selection, trial monitoring, reporting, record keeping, and prohibitions on the promotion of investigational devices. The investigators must obtain patient informed consent, rigorously follow the investigational plan and study protocol, control the disposition of investigational devices, and comply with all reporting and record-keeping requirements. Required records and reports are subject to inspection by the FDA. Prior to granting PMA approval, the FDA typically inspects the records relating to the conduct of the study and the clinical data supporting the PMA application for compliance with IDE requirements.

In January 2008, the FDA audited the conduct of the feasibility study and pivotal clinical trial of our UniFit Abdominal Stent Graft. As a result of this audit, the FDA issued a formal notification, or Form FDA-483, listing nine observations. Specifically, the FDA observed that we had not adequately supervised participating sites, made all required reports to those sites and the FDA, or adequately maintained all records required by FDA regulations. In June 2008, the FDA issued a public Warning Letter regarding many of the matters cited in the Form FDA-483. After receiving this Warning Letter, we submitted a response letter to the FDA detailing our implementation of corrective actions, and in July 2008, we received a letter from the FDA indicating that the corrective actions that we have developed and implemented appear to be adequate. In February 2010, the FDA conducted a follow-up audit of the feasibility study and pivotal clinical trial. At this time we are not aware of any adverse findings, but our corrective actions remain subject to further verification as part of any future inspection, and we cannot assure you that we have been or will continue to be successful in implementing these changes or that the FDA will continue to agree that our implementation is adequate. If the FDA determines that we are not in substantial compliance with IDE requirements, they may take enforcement action against us, and the conduct of our clinical trial could be interrupted or discontinued.

Although the QSR does not fully apply to investigational devices, the requirement for controls on design and development does apply. The sponsor also must manufacture the investigational device in conformity with the quality controls described in the IDE application and any conditions of IDE approval that FDA may impose with respect to manufacturing.

Historically, our products have been introduced into the market using the 510(k) clearance procedure, and we have not used the more burdensome PMA process for any of the products that we currently market or sell in the United States. In contrast, the FDA is requiring that both our UniFit Abdominal Stent Graft and TAArget Thoracic Stent Graft undergo the PMA process.

Postmarket Regulation

After a device is placed on the market, regardless of the classification or premarket pathway, significant regulatory requirements apply. These include:

•

manufacturing establishment registration and device listing with the FDA;

•

the QSR, which requires finished device manufacturers, including third-party or contract manufacturers, to follow stringent design, testing, control, documentation, and other quality assurance procedures in all aspects of manufacturing;

•

labeling regulations and FDA prohibitions against the promotion of products for uncleared, unapproved, or off-label uses and other requirements related to promotional activities;

•

medical device reporting regulations, which require that manufacturers report to the FDA if their device may have caused or contributed to a death or serious injury or malfunctioned in a way that would likely cause or contribute to a death or serious injury if the malfunction were to recur; and

•

corrections and removal reporting regulations, which require that manufacturers report to the FDA any field corrections and product recalls or removals if undertaken to reduce a risk to health posed by the device or to remedy a violation of the FDCA that may present a risk to health.

We are subject to inspection and marketing surveillance by the FDA to determine our compliance with regulatory requirements. Non-compliance with applicable FDA requirements can result in, among other things, public warning letters, fines, injunctions, civil penalties, recall or seizure of products, total or partial suspension of production, failure of the FDA to grant marketing approvals, withdrawal of marketing approvals, a recommendation by the FDA to disallow us to enter into government contracts, and criminal prosecutions. The FDA also has the authority to request repair, replacement, or refund of the cost of any device manufactured or distributed by us. In the event that one of our suppliers fails to maintain compliance with our quality requirements, we may have to qualify a new supplier and could experience manufacturing delays as a result.

Non-U.S. sales of medical devices manufactured in the United States that are not approved or cleared by the FDA for use in the United States, or are banned or deviate from lawful performance standards, are subject to FDA export requirements. Before exporting such products to a foreign country, we must first comply with the FDA’s regulatory procedures for exporting unapproved devices.

Other U.S. Regulations

We and our products are also subject to a variety of state and local laws in those jurisdictions where our products are or will be marketed, and federal, state, and local laws relating to matters such as safe working conditions, manufacturing practices, environmental protection, fire hazard control, and disposal of hazardous or potentially hazardous substances. We are subject to various federal and state laws governing our relationships with the physicians and others who purchase or make referrals for our products. For instance, federal law prohibits payments of any form that are intended to induce a referral for any item payable under Medicare, Medicaid, or any other federal healthcare program. Many states have similar laws. There can be no assurance that we will not be required to incur significant costs to comply with such laws and regulations now or in the future or that such laws or regulations will not have a material adverse effect upon our ability to do business.

We are subject to federal, state, and local laws, rules, regulations, and policies governing the use, generation, manufacture, storage, air emission, effluent discharge, handling, and disposal of certain hazardous and potentially hazardous substances used in connection with our operations. Although we believe that we have complied with these laws and regulations in all material respects and to date have not been required to take any action to correct any noncompliance, there can be no assurance that we will not be required to incur significant costs to comply with environmental regulations in the future.

Non-U.S. Regulation

Sales of medical devices are subject to regulatory requirements in many countries. The regulatory review process may vary greatly from country to country. For example, the European Union has adopted numerous directives and standards relating to medical devices regulating their design, manufacture, clinical trials, labeling, and adverse event reporting, including the Medical Devices Directive (93/42/EEC), which is applicable to our products. Devices that comply with the requirements of the Medical Devices Directive are entitled to bear a Conformité Européenne, or CE mark, indicating that the device conforms with the essential requirements of the applicable directive and can be commercially distributed in countries that are members of the European Union, as

well as Iceland, Lichtenstein, Norway, and Switzerland. Each member state of the European Union has implemented the directives into its respective national law and has each established a “Competent Authority” to apply the directive in its territory.

The Directive defines a classification system placing devices into Class I, IIa, IIb, or III, depending on the risks and characteristics of the medical device. The Directive also defines the essential requirements that devices must meet before being placed on the market, establishes assessment procedures for approving a device for marketing, and creates mechanisms for national authorities to manage implementation or to intervene when public health requires. Essential requirements include manufacturing, design, performance, labeling, and safety requirements, and may include providing certain clinical data. These requirements vary based on the type of the device and other related factors.

A manufacturer of low-risk devices typically may demonstrate conformity to the essential requirements based on a self-declaration. The European Standardization Committees have adopted numerous harmonized standards for specific types of medical devices. Compliance with relevant standards establishes a presumption of conformity with the essential requirements. Manufacturers of higher-risk devices generally must use a “Notified Body”—an appointed independent third party to assess conformity. This third-party assessment may consist of an audit of the manufacturer’s quality system and specific testing of the manufacturer’s devices. An assessment by a Notified Body in one country within the European Union is generally required in order for a manufacturer to commercially distribute the product throughout the European Union. Most of our devices are considered higher-risk devices that require Notified Body assessment.

The European medical device laws also address the advertising and promotion of medical devices, clinical investigations, and requirements for handling adverse events. Post-market surveillance of medical devices in the European Union is generally conducted on a country-by-country basis; however, the Directive sets forth certain specific requirements for reporting adverse events. The Medical Device Vigilance system is the mechanism by which adverse event reporting is managed and monitored in the European Union.

In some cases, we rely on our non-U.S. distributors to obtain premarket approvals, complete product registrations, comply with clinical trial requirements, and complete those steps that are customarily taken in the applicable jurisdictions to comply with governmental and quasi-governmental regulation. In the future, we expect to continue to rely on distributors in this manner in those countries where we continue to market and sell our products through them.

In Japan, the Ministry of Health, Labor and Welfare (MHLW) regulates medical devices through the Pharmaceutical Affairs Law, which was reformed effective April 1, 2005. The revisions to Japan’s regulations have resulted in longer lead times for product registration.

There can be no assurance that new laws or regulations or new interpretations of laws and regulations regarding the release or sale of medical devices will not delay or prevent sale of our current or future products.

Third-Party Reimbursement

United States

Healthcare providers that purchase medical devices generally rely on third-party payors, including the Medicare and Medicaid programs and private payors (such as indemnity insurers, employer group health insurance programs, and managed care plans) to reimburse all or part of the cost of those products. As a result, demand for our products is and will continue to be dependent in part on the coverage and reimbursement policies of these payors. The manner in which reimbursement is sought and obtained varies based upon the type of payor involved and the setting in which the product is furnished and utilized. Furthermore, payments from Medicare, Medicaid, and other third-party payors are subject to legislative and regulatory changes and are susceptible to budgetary pressures.

In the United States, third-party payors generally pay healthcare providers directly for the procedures they perform and in certain instances for the products they use. Alternatively, third-party payors may reimburse patients for all or part of the charges that patients pay for procedures and the products used in connection with those procedures. In either case, our sales volumes depend on the extent to which third-party payors cover our products and the procedures in which they are used. In general, a third-party payor only covers a medical product or procedure when the plan administrator is satisfied that the product or procedure is medically necessary because it improves health outcomes, including quality of life or functional ability, in a safe and cost-effective manner. Even if a device has received clearance or approval for marketing by the FDA, there is no assurance that third-party payors will cover the cost of the device and related procedures in which the device is used.

In many instances, third-party payors cover the procedures performed using our products using price fee schedules that do not vary reimbursement to reflect the cost of the products and equipment used in performing those procedures. In other instances, payment or reimbursement is separately available for the products and equipment used, in addition to payment or reimbursement for the procedure itself. Even if coverage is available, third-party payors may place restrictions on the circumstances in which they provide coverage or may offer reimbursement that is not sufficient to cover the cost of our products. Many of the products that compete with ours are less expensive. Therefore, although coverage may be available for our products and the related procedures, the levels of approved coverage may not be sufficient to justify using our products instead of those of competitors.

Third-party payors are increasingly challenging the prices charged for medical products and procedures and, where a reimbursement model is used, introducing maximum reimbursement limits for the procedures they cover. We believe that the minimally invasive procedures in which most of our products are used are generally less costly than open surgery because they frequently result in shorter hospitalization times. However, there is no guarantee that these procedures will be reimbursed. Third-party payors may not consider these minimally invasive procedures to be cost-effective and therefore refuse to authorize coverage.

Finally, the advent of contracted fixed rates per procedure has made it difficult to receive separate reimbursement for disposable products, even if the use of these products improves clinical outcomes. In addition, many third-party payors are moving to managed care systems in which providers contract to provide comprehensive healthcare for a fixed cost per person. Managed care providers often attempt to control the cost of healthcare by authorizing fewer elective surgical procedures. Under current prospective payment systems, such as the diagnosis-related group system and the hospital out-patient prospective payment system, both of which are used by Medicare and in many managed care systems used by private third party payors, the reimbursement for our products will be incorporated into the overall reimbursement of a procedure, and there will be no separate reimbursement for our products. As a result, we cannot be certain that hospital administrators and physicians will purchase our products.

If hospitals and physicians cannot obtain adequate reimbursement for our products or the procedures in which they are used, our business, financial condition, and results of operations could suffer a material adverse impact.

Non-U.S.

Our success in non-U.S. markets will depend largely upon the availability of reimbursement from the third-party payors through which healthcare providers are paid in those markets. Reimbursement and healthcare payment systems in non-U.S. markets vary significantly by country. The main types of healthcare payment systems are government sponsored healthcare and private insurance. As in the United States, reimbursement is subject to legislative and regulatory changes and is susceptible to budgetary pressures. Reimbursement approval must be obtained individually in each country in which our products are marketed. Outside the United States, we generally pursue reimbursement approval in those countries in which we sell directly to the hospital. In other markets, we generally rely on the distributors who sell our products to obtain reimbursement approval in those countries in which they will sell our products. There can be no assurance that reimbursement approval will be received.

Fraud and Abuse Laws

We may directly or indirectly be subject to various federal and state laws pertaining to healthcare fraud and abuse, including anti-kickback laws. In particular, the federal healthcare program Anti-Kickback Statute prohibits persons from knowingly and willfully soliciting, offering, receiving, or providing remuneration, directly or indirectly, in exchange for or to induce either the referral of an individual, or the furnishing, arranging for, or recommending a good or service for which payment may be made in whole or part under federal healthcare programs, such as the Medicare and Medicaid programs. Penalties for violations include criminal penalties and civil sanctions such as fines, imprisonment, and possible exclusion from Medicare, Medicaid, and other federal healthcare programs. The Anti-Kickback Statute is broad and prohibits many arrangements and practices that are lawful in businesses outside of the healthcare industry. In implementing the statute, the Office of Inspector General, or OIG, has issued a series of regulations, known as the “safe harbors.” These safe harbors set forth provisions that, if all their applicable requirements are met, will assure healthcare providers and other parties that they will not be prosecuted under the Anti-Kickback Statute. The failure of a transaction or arrangement to fit precisely within one or more safe harbors does not necessarily mean that it is illegal or that prosecution will be pursued. However, conduct and business arrangements that do not fully satisfy each applicable element of a safe harbor may result in increased scrutiny by government enforcement authorities, such as the OIG.

Employees

We had 227 full-time employees at December 31, 2009. Of these employees, 91 were in manufacturing and research and development, 92 were in sales and marketing, 20 were in clinical, regulatory, and quality assurance, and 24 were in general and administrative. We have never had a work stoppage.

At our facility in Brindisi, Italy, we have 29 employees who are covered by one or more collective bargaining agreements negotiated with a union-authorized employee representative (Rappresentanza Sindacale Unitaria) and the two unions (FEMCA-CISL and FILCEA-CGIL) that represent employees at this location. In February 2010, these unions declared a Stato di Agitazione, which is a method in Italy by which an employee union indicates to an employer that the union membership may be considering the initiation of a work stoppage, work slowdown or other direct action.

Financial Information by Business Segment and Geographic Data

We operate in one reportable industry segment: the design, marketing, sales and technical support of medical devices and implants for the treatment of peripheral vascular disease. Our chief operating decision maker is our chief executive officer. Our chief executive officer reviews financial information, accompanied by information about revenue by geographic region for purposes of allocating resources and evaluating financial performance. The information included in Note 14 of the Notes to Consolidated Financial Statements is hereby incorporated by reference.

Customers

Our sales are not dependent on any single customer or distributor, and we continue to expand our distribution channel worldwide through direct and indirect sales forces.

Item 1A.

Risk Factors

The following important factors, among others, could cause our actual operating results to differ materially from those indicated or suggested by forward-looking statements made in this Form 10-K or presented elsewhere by management from time to time. Investors should carefully consider the risks described below before making an investment decision. The risks described below are not the only ones we face. Additional risks not presently known to us or that we currently believe are immaterial may also significantly impair our business operations. Our business could be harmed by any of these risks. The trading price of our common stock could decline due to any of these risks, and investors may lose all or part of their investment.

Risks Related to Our Business

We may experience significant fluctuations in our quarterly and annual results.

Fluctuations in our quarterly and annual financial results have resulted and will continue to result from numerous factors, including:

•

strategic actions by us, such as acquisitions of additional businesses, products, or technologies;

•

costs incurred in connection with the termination of contractual and other relationships, including distributorships;

•

changes in the mix of products we sell;

•

the relocation of manufacturing operations and other strategic restructuring;

•

the discontinuation of a product line or other revenue generating activity, such as private label manufacturing;

•

the expiration or exhaustion of deferred tax assets such as net operating loss carry-forwards;

•

increased product and price competition;

•

seasonality in the sales of our products;

•

the loss of any significant customer, especially in regard to any product that has a limited customer base; and

•

effects of domestic and foreign economic conditions and exchange rates on our industry and/or customers.

These factors, some of which are not within our control, may cause the price of our common stock to fluctuate substantially. If our quarterly operating results fail to meet or exceed the expectations of securities analysts or investors, our stock price could drop suddenly and significantly. We believe the quarterly comparisons of our financial results are not always meaningful and should not be relied upon as an indication of our future performance.

We may not maintain our recent profitability

As of December 31, 2009, we had an accumulated deficit of approximately $14.6 million. While we reported positive operating and net income for the year ended December 31, 2009, we had an operating and a net loss for the year ended December 31, 2008 and 2007. There can be no assurance we will achieve significant net sales gains or maintain either operating or net profitability in the future. Our recent operating and net profitability result in part from extensive operating expense reduction. Control of operating expenses may need to be maintained in order to maintain or improve operating profitability, and decreased investment levels may inhibit future growth in net sales and earnings. We intend to increase operating expenses in 2010 in areas such as sales

and marketing, research and development, and clinical and regulatory affairs. Additionally, our ability to maintain and increase profitability will be influenced by many factors, including:

•

the level and timing of future sales, manufacturing costs and operating expenditures;

•

market acceptance of our new products;

•

the productivity of our direct sales force and distributors;

•

fluctuations in foreign currency exchange rates;

•

the cost of our clinical studies;

•

our ability to successfully acquire and develop competitive products;

•

our ability to successfully integrate acquired businesses, products, or technologies;

•

the impact on our business of competing products, technologies, and procedures;

•

our ability to obtain regulatory approvals for our products in new markets;

•

market and regulatory developments; and

•

the cost of intellectual property challenges, if any.

Fluctuations in foreign currency exchange rates could result in declines in our reported sales and earnings.

For the full year ended December 31, 2009, 42% of net sales were derived from sales occurring outside of the Unites States. Because the majority of our sales outside of the United States are denominated in local currencies, our reported sales and earnings are subject to fluctuations in foreign exchange rates. We cannot predict the impact of foreign currency fluctuations, and foreign currency fluctuations in the future may adversely affect our sales and earnings. At present, we manufacture very few of our products outside the United States and we rarely engage in hedging transactions to protect against uncertainty in future exchange rates between particular foreign currencies and the U.S. dollar. Over recent months, the value of foreign currencies against the U.S. dollar has fluctuated dramatically. For example, the value of the euro against the U.S. dollar declined by approximately 5% during the first two months of 2010. A decline in the value of the euro against the U.S. dollar could be expected to have a negative impact on our revenue and earnings growth as euro-denominated revenues and earnings, if any, would be translated into U.S. dollars at a reduced value.

We may acquire businesses and assets in the future. We may experience difficulties in completing the integration of these acquisitions into our business, or we may not realize the anticipated benefits of these acquisitions.

In order to expand our product offerings, we have completed ten acquisitions since 1998, and a key part of our strategy is to acquire additional businesses, products, or technologies in the future. Our growth strategy depends in part upon our ability to identify, negotiate, complete, and integrate suitable acquisitions and develop products from uncommercialized intellectual property that we acquire. If we are unable to complete acquisitions on satisfactory terms, our growth objectives could be negatively affected.

Even if we complete acquisitions, we may experience:

•

difficulties in integrating any acquired companies, personnel, and products into our existing business;

•

difficulties in integrating manufacturing operations into our existing business or successfully replicating manufacturing processes at new manufacturing facilities;

•

difficulties or delays in transitioning clinical studies or unfavorable results from such clinical studies;

•

difficulties or delays in commercializing intellectual property that we acquire;

•

diversion of our management’s time and attention from other business concerns;

•

challenges resulting from limited or no prior experience in new markets or countries we may enter;

•

higher costs of integration than we anticipated;

•

difficulties in retaining key employees of the acquired business who are necessary to manage these acquisitions;

•

difficulties in acquiring the rights to and protecting intellectual property; or

•

difficulties if the acquired company is remote or inconvenient to our Burlington, Massachusetts, headquarters.

For any of these reasons or as a result of other factors we may not realize the anticipated benefits of acquisitions and our operating results may be harmed.

For example, following our acquisition of Biomateriali S.r.l. in December 2007, we were informed by Sorin Biomedica SpA, that Sorin would be reducing its purchases under an existing private label manufacturing program with Biomateriali. We estimate that this change in purchase volume resulted in a 22% reduction, approximately, in annual net sales of Biomateriali compared to annual net sales for the year preceding the acquisition. We can provide no assurance that similar changes in purchasing volume will not occur in the future in regard to Sorin or any other private label customer of, or distributor for, a company that we acquire.

We also may experience other difficulties related to our acquisitions. For example, the products that we have acquired may need to be improved in order to gain broader market acceptance or may not compete effectively with existing products. We may have limited experience with certain technologies underlying the acquired products. There can be no assurance that we will be successful developing the desired product improvements in a timely manner, if at all.

We could also discover deficiencies withheld from us due to fraud or otherwise not uncovered in our due diligence prior to the acquisition, including deficiencies in internal controls, data adequacy and integrity, product quality, and regulatory compliance, as well as undisclosed and product liabilities, any of which could result in us becoming subject to penalties or other liabilities.

An acquisition may require debt or equity financing. Equity financing, if available, may be dilutive to our stockholders. If we raise additional capital through the issuance of debt, this debt will be senior to our outstanding shares of capital stock upon our liquidation, and interest payments to a lender may divert our capital away from alternative spends or investments.

Any of these difficulties could negatively impact our ability to realize the intended and anticipated benefits that we currently expect from our acquisitions and could harm our financial condition and results of operations.

If we are unable to expand our product offerings, we may not achieve our growth objectives and our results of operations could suffer.

We may not be able to compete effectively with our competitors unless we can keep pace with existing or new products and technologies in the vascular device market. Our success in developing and commercializing new products and new versions of our existing products is affected by our ability to:

•

identify in a timely manner new market trends and customer needs;

•

keep pace with technological changes and industry standards;

•

obtain regulatory clearance or approval of new products and technologies;

•

successfully develop cost-effective manufacturing processes for such products;

•

commercially introduce such products and technologies; and

•

achieve market acceptance.

If we are unable to expand our product offerings, we may not achieve our growth objectives and our results of operations could suffer.

We face intense competition from other companies, technologies, and alternative medical procedures and we may not be able to compete effectively.

The markets in which we compete are highly competitive, subject to change, and significantly affected by new product introductions and other activities of industry participants. Although no one company competes against us in all of our product lines, a number of manufacturers of peripheral vascular devices have substantially greater capital resources, larger customer bases, broader product lines, larger sales forces, greater marketing and management resources, larger research and development staffs, and larger facilities than ours; have established reputations with our target customers; and have developed worldwide distribution channels that are more effective than ours. Our competitors could elect to devote additional resources to the markets in which we currently enjoy less competition. Also, although we currently have leading market positions in the markets for some of our products, this is not true for the markets for all of our products, in particular our endovascular products. We have from time to time experienced difficulties competing against very large companies. For example, we believe that intense competition from Medtronic, W. L. Gore and Cook has been a significant factor in inhibiting the adoption of our TAArget Thoracic Stent Graft in European markets.

Recent industry consolidation could make the competitive environment more difficult for smaller companies like ours. Because of the size of the vascular disease market opportunity, competitors and potential competitors have dedicated, and we believe will continue to dedicate, significant resources to aggressively promote their products. Also, new product developments that could compete with us more effectively are likely because the vascular disease market is characterized by extensive research efforts and technological progress. Competitors may develop technologies and products that are safer, more effective, easier to use, less expensive, or more readily accepted than ours. Their products could make our technology and products obsolete or noncompetitive. Our competitors may also be able to achieve more efficient manufacturing and distribution operations than we can. In addition, many of our products face competition from alternative procedures that utilize a different kind of medical device that we do not currently sell. Increased competition could also result in price reductions and loss of market share, any of which could result in lower revenues and reduced gross profits.

If we fail to convert additional countries or products from distributor sales to direct sales, or encounter difficulties in effecting such conversions, our results of operations could suffer.

We intend to convert select countries and products from distributor sales to direct sales, which could result in disruptions in our sales. This transition may also have an adverse effect on our cash flow from operations because distributors, unlike direct sales personnel, pay us for inventory that they stock for later sale. In addition, switching to a direct sales force may subject us to longer customer collection times and larger bad debt expense, since we would be required to collect customer payments directly rather than through a distributor. Also, our distribution agreements are typically exclusive with terms of up to five years. These agreements may temporarily constrain our ability to convert certain countries or products from a distributor to a direct sales model. Further, even where the payment of compensation is not required by contract or local law, it may be prudent to make such a payment in order to assure a successful market transition. For example, in October 2007 we entered into an agreement with our exclusive distributor in Italy to end its distribution of our products in January 2008. Among the payments made under this agreement were consulting and transition services fees. These payments were not required under an existing contract or Italian law. These amounts were paid in part because the absence of cooperation by a distributor may result in the sudden erosion of our customer base, which could materially harm

our ability to sell our product in that country. If we elect to cooperate with a distributor, that distributor may require us to repurchase inventory that we had previously sold to that distributor, in which event we may need to make a corresponding negative adjustment to net sales.

Following termination of any distribution relationship, we may encounter difficulties in transitioning to a direct-sales model in any country in question. It may take us longer than expected to find sufficient qualified sales personnel to establish an effective sales force, which could negatively impact projected sales. If a distributor sold our products through a network of sales agents, rather than exclusively through its own personnel, we may not be able to establish relationships with all members of that network, temporarily limiting our access to the existing market. Similarly, failure to maintain or quickly re-establish a distributor’s close relationships with the physicians who use our products could cause a drop in sales. On the logistical side, if a distributor entered into an agreement with a customer relating to sales of our products or successfully completed a customer’s internal approval process, it may be difficult or impossible to assign the distributor’s rights under such agreements or approvals, and sales to that customer may be delayed until a new agreement is entered or a new approval is obtained. The transition to a direct sales model may also require us to incur additional expenses and meet regulatory requirements that were previously the responsibility solely of the distributor. As a result of these risks, there can be no assurance that we will be successful in transitioning to a direct sales model in the countries or for the products that we select, and difficulties that we encounter in this transition could negatively affect our business.

Current economic instability may harm our operating results.

Financial markets and the economies in the United States and internationally have recently experienced disruption and volatility and conditions could worsen. As a result, the economic environment may, among other things:

•

create downward pressure on the pricing of our products;

•

affect the collection of accounts receivable;

•

increase the sales cycle for certain of our products;

•

slow the adoption of new technology;

•

adversely affect our customers, causing them to reduce spending; and

•

adversely affect our suppliers, which could disrupt our ability to produce our products.

Any of these conditions could harm our operating results and liquidity.

If we are unable to increase our selling prices to customers, our rate of net sales growth might be reduced and our operating results could suffer.

In the fiscal years ended December 31, 2008 and 2009, a material portion of our increases in net sales was driven by higher average selling prices to our hospital customers across several of our product lines, particularly with respect to sales occurring in the United States. We have in the past been able to rely upon our intellectual property position, our well-known brands, our established reputation in the vascular surgery device marketplace, and, in some cases, an absence of competition, to implement price increases. If healthcare spending is reduced, particularly in the United States, in response either to government-enacted healthcare reform or to general economic conditions, if the reimbursement rates for the medical procedures in which our products are used are reduced or constrained, or if competitors introduce lower-priced products of comparable safety and efficacy, we may become unable to implement further increases in the selling prices of our products. If we become unable to raise selling prices, it might reduce our rate of net sales growth, which could harm our operating results.

If there is a disruption in the supply of products that we distribute, or if our relationships with their manufacturers are impaired, our net sales and results of operations would be harmed.

We are party to an agreement with Endologix, Inc. to distribute the Powerlink System in several European countries, including Germany, France, and the United Kingdom. We are party to agreements with Neovasc Inc. to distribute the XenoSure Biologic Vascular Patch in the United States and most of Europe. If we are unable to market these products successfully, or if our agreement with either manufacturer is terminated early, our net sales and results of operations would likely suffer. In each case, if we do not meet our minimum purchase requirements under our agreement, and do not cure this deficiency, the agreement may be terminated by the manufacturer. In the case of Endologix we have not always met these performance requirements. There can be no assurance that our minimum purchase obligations will not exceed the market demand for the Powerlink System, which is dependent upon many risks outside our control. Were Endologix to declare a default under our agreement with them, we would be permitted to cure the performance requirement by purchasing additional inventory in order to avoid a termination, but these required purchases may be material in amount, reducing our cash reserves.

In addition, even if we market our distributed products successfully, if the manufacturer is unable to produce enough of its products to meet our demands, we may not be able to meet our customers’ demands, and our net sales and results of operations may suffer.

Some of our devices have been recently introduced into the market and may not achieve market acceptance, which could adversely affect our business.

Some of our devices have been recently introduced into the market, and we cannot assure you that they will achieve market acceptance. The same is true of new devices that we may acquire or internally develop in the future. The marketing of our products requires a significant amount of time and expense in order to identify and develop relationships with the physicians who may use our products, invest in training and education with these physicians, and employ a sales force that is large enough to interact with the targeted physicians, with no assurance of success. In some cases, our devices may face competition from devices marketed by our competitors, and our customers may not prefer our devices. In other cases, our devices may be used in new procedures and techniques, and if physicians do not adopt these procedures and techniques, demand for these devices would fail to develop. For example, in 2004 we launched our InvisiGrip Vein Stripper, which has not achieved widespread market adoption because of competing products and techniques. If our products do not gain market acceptance, our business could be adversely affected.

If we are unable to manage the anticipated growth of our business, our financial condition and operating results could be adversely affected.

The growth that we have experienced, and may experience in the future, will continue to provide challenges to our organization. For example, since 1998 we have completed ten acquisitions, and we expect to pursue additional acquisitions in the future. As our operations expand, both in terms of scope and geographic coverage, we expect that we will need to manage additional relationships with various partners, suppliers, and other organizations. We also will need to manage the corresponding growth of our manufacturing operations. Our ability to manage our operations and growth requires us to continue to improve our operational, financial, and management controls and reporting systems and procedures, and may in the future require us to transition to new enterprise management software. Such growth could place a strain on our administrative and operational infrastructure. We may not be able to make improvements to our management information and control systems in an efficient or timely manner, and we may discover deficiencies in existing systems and controls. If we cannot scale and manage our business appropriately, our anticipated growth may be impaired and our financial results could suffer.

The risks inherent in operating internationally and the risks of selling and shipping our products and of purchasing our components and products internationally may adversely impact our net sales, results of operations, and financial condition.

We derive a significant portion of our net sales from operations in markets outside of the United States and Canada. For the full year ended December 31, 2009, 42% of our net sales were derived from our operations outside of the United States and Canada. Our international sales operations expose us and our representatives, agents, and distributors to risks inherent in operating in foreign jurisdictions. These risks include:

•

fluctuations in foreign currency exchange rates;

•

the imposition of additional U.S. and foreign governmental controls or regulations, including export licensing requirements, duties and tariffs, and other trade restrictions;

•

the risk of non-compliance with the Foreign Corrupt Practices Act by our sales representatives or our distributors;

•

the imposition of U.S. and/or international sanctions against a country, company, person, or entity with whom we do business that would restrict or prohibit continued business with the sanctioned country, company, person, or entity;

•

a shortage of high-quality sales personnel and distributors;

•

loss of any key personnel who possess proprietary knowledge, or who are otherwise important to our success in certain international markets;

•

changes in third-party reimbursement policies that may require some of the patients who receive our products to directly absorb medical costs or that may necessitate the reduction of the selling prices of our products;

•

the imposition of restrictions on the activities of foreign agents, representatives, and distributors;

•

scrutiny of foreign tax authorities, which could result in significant fines, penalties, and additional taxes being imposed on us;

•

pricing pressure that we may experience internationally;

•

laws and business practices favoring local companies;

•

longer payment cycles;

•

difficulties in enforcing agreements and collecting receivables through certain foreign legal systems;

•

difficulties in enforcing or defending intellectual property rights;

•

exposure to different legal and political standards; and

•

political, economic, and/or social instability.

We cannot assure you that one or more of these factors will not harm our business. Any material decrease in our international sales would adversely impact our net sales, results of operations, and financial condition.

We depend on single- and limited-source suppliers for some of the components to our products, as well as for acquired products that have not been transitioned to in-house manufacture, and if any of those suppliers are unable or unwilling to supply them on acceptable terms, it could limit our ability to deliver our products to our customers on a timely basis or at all.

We rely on single- and limited-source suppliers for some of our important product components, as well as for products we have acquired that are not manufactured in-house. For example, we obtain from a third-party supplier a key component used in our TAArget Thoracic Stent Graft and UniFit Abdominal Stent Graft.

Similarly, the EndoRE remote endarterectomy product line we added as a result of the Vascular Architects acquisition is manufactured for us by third-party suppliers. There are relatively few, or in some cases no, alternative, validated sources of supply for these components and products. We do not have supply agreements with most of these suppliers, and instead place orders on an as-needed basis. Most of these suppliers could discontinue the manufacture or supply of these components or products at any time. We do not carry a significant inventory of these components and products. Identifying and qualifying additional or replacement suppliers, if required, may not be accomplished quickly or at all and could involve significant additional costs. Any supply interruption from our vendors or failure to obtain additional vendors for any of the components used to manufacture our products would limit our ability to manufacture our products, may result in production delays and increased costs, and may limit our ability to deliver products to our customers. If we are unable to identify alternate sources of supply for the components, we would have to modify our products to use substitute components, which may cause delays in shipments, increase design and manufacturing costs, and increase prices for our products. We cannot assure you that any such modified products would be as effective as the predecessor products, or that such modified products would gain market acceptance. This could lead to customer dissatisfaction and damage to our reputation.

Any disruption in our manufacturing facilities could harm our results of operations.

Our principal worldwide executive, distribution, and manufacturing operations are located at a 27,098 square foot leased facility and a nearby 7,477 square foot leased facility located in Burlington, Massachusetts. We also manufacture our AlboGraft Vascular Graft product line and perform select other manufacturing processes in a 16,146 square foot leased facility in Brindisi, Italy. These facilities and the manufacturing equipment we use to produce our products would be difficult to replace and could require substantial lead-time to repair or replace in the event of a natural or man-made disaster. In such event, we could not shift production to alternate manufacturing facilities, and we would be forced to rely on third-party manufacturers. Although we possess insurance for damage to our property and the disruption of our business from casualties, such insurance may not be sufficient to cover all of our potential losses, including potential damage to our reputation, and may not continue to be available to us on acceptable terms, or at all.

At our facility in Brindisi, Italy, nearly all of our employees are covered by one or more collective bargaining agreements negotiated with a union-authorized employee representative (Rappresentanza Sindacale Unitaria) and the two unions (FEMCA-CISL and FILCEA-CGIL) that represent employees at this location. In February 2010, these unions declared a Stato di Agitazione, which is a method in Italy by which an employee union indicates to an employer that the union membership may be considering the initiation of a work stoppage, work slowdown or other direct action. If these unions initiate a work stoppage, the supply of our AlboGraft Vascular Graft may be interrupted, we may not be able to meet our customers’ demands for the product, and our net sales and results of operations may suffer.

Our primary focus on the needs of vascular surgeons could harm our business if interventional cardiologists and interventional radiologists perform a greater percentage of new procedures that replace those procedures traditionally performed by vascular surgeons, or if vascular surgeons increasingly specialize in procedures for which we do not sell devices.

The treatment of peripheral vascular disease is increasingly shifting from open vascular surgery to minimally invasive endovascular procedures. We market and sell our products primarily to vascular surgeons, who in addition to performing traditional open surgical procedures, in growing numbers also perform minimally invasive, image-guided interventional procedures for peripheral vascular disease. However, vascular surgeons may not adopt these procedures in the numbers we expect and instead these procedures may be largely performed by interventional cardiologists and interventional radiologists. Many of our competitors have focused their sales efforts on these interventionalists. If interventional cardiologists and interventional radiologists perform a greater percentage of these new procedures than we expect, our net sales may decline.

Moreover, demographic trends and other market factors, such as reimbursement rates, are driving vascular surgeons in the United States and potentially in other markets to increasingly specialize in certain kinds of procedures, such as endovascular therapies, the creation and maintenance of dialysis access sites, and the treatment of varicose veins. Sometimes these physicians will discontinue performing other vascular procedures. If this trend continues, it could lead to the fragmentation of our customer base, which would reduce cross-selling opportunities and the efficiency of each sales call by our sales representatives, which in turn would negatively impact our business.

We depend on our senior management team and other key scientific, sales, and technical personnel, and if we are unable to retain them or recruit additional qualified personnel we may not be able to manage our operations and meet our strategic objectives.

We depend on the continued services of our senior management team and other key scientific, sales, and technical personnel, as well as our ability to continue to attract and retain additional highly qualified personnel. Our ability to retain our skilled labor force and our success in attracting and hiring new skilled employees will be a critical factor in determining whether we will be successful in the future. Each of our key employees may terminate his or her employment with us at any time. The loss of any of our senior management team or key employees could harm our business. We compete for such personnel with other companies, academic institutions, government entities, and other organizations. We may not be able to meet our future hiring needs or retain existing personnel on acceptable terms. We could face significant challenges and risks in hiring, training, managing, and retaining engineering and sales employees. Any loss or interruption of the services of our other key personnel could also significantly reduce our ability to effectively manage our operations and meet our strategic objectives, because we cannot assure you that we would be able to find an appropriate replacement should the need arise. We maintain life insurance payable to us on our Chairman and Chief Executive Officer, George W. LeMaitre, but not on our other key personnel.

If we do not maintain our relationships with our physician customers, our growth may be limited and our business could be harmed.

Physicians typically influence the medical device purchasing decisions of the hospitals and other healthcare institutions in which they practice. Consequently, our relationships with our physician customers are critical to our continued growth. We believe that these relationships are based on our long-standing reputation and presence in the market for peripheral vascular devices, the quality of our product offerings and clinical outcomes, our marketing efforts and our presence at medical society meetings. Any actual or perceived diminution in our reputation or the quality of our products or our failure or inability to maintain these other efforts could damage our current relationships, or prevent us from forming new relationships, with physicians and cause our growth to be limited and our business to be harmed.

Our lack of customer purchase contracts makes it difficult to predict sales and plan manufacturing requirements, which could lead to lower net sales, higher expenses, and reduced margins.

We generally do not have long-term purchase contracts with our hospital customers, who typically order products on an as-needed basis. As a result, it is difficult to accurately forecast our component and product requirements. Our manufacturing and operating expenses are largely based on anticipated sales volume, and a significant portion of these expenses is and will continue to be fixed. We must plan production and order product components and third-party manufactured products several months in advance of customer orders. In addition, lead times for product components and third-party manufactured products that we order vary significantly and depend on factors such as the specific supplier and demand for each component at any given time. These factors expose us to a number of risks, such as the following:

•

if we overestimate our requirements, or experience shortages, we may be obligated to carry more inventory than we need, which could result in write-offs of excess or obsolete inventory;

•

if we underestimate our requirements, we may have an insufficient product component inventory, which could disrupt manufacturing of our products and cause delays in shipments and net sales; and

•

if we experience shortages of product components from time to time, which could delay the manufacturing and shipping of our products.

If any of the foregoing occurs, it could lead to lower net sales, higher expenses, and reduced margins.

The use or misuse of our products may result in injuries that lead to product liability suits, which could be costly to our business.

Although we offer training for physicians in the use of some of our products, we do not require that physicians be trained in the use of our products. Not requiring training specific to the use of our devices may expose us to greater risk of product liability if injuries occur during a procedure involving our products. In addition, if demand for our products continues to grow, less skilled surgeons will likely use the devices, potentially leading to an increased incidence of patient injury and an increased risk of product liability.

If our products are defectively designed, manufactured, or labeled, contain defective components, or are misused, or if our products are found to have caused or contributed to injuries or death, we may become subject to costly litigation by our customers or their patients. We are from time to time involved in product liability claims. Product liability claims could divert management’s attention from our core business, be expensive to defend, and result in sizable damage awards against us. Claims of this nature may also adversely affect our reputation, which could damage our position in the market and subject us to product recalls.

We cannot assure you that our product liability insurance coverage will be sufficient to satisfy any claim made against us. Further, we may not be able to maintain the same level of coverage, and we may not be able to obtain adequate coverage at a reasonable cost and on reasonable terms, if at all. Any product liability claim brought against us, with or without merit, could increase our product liability insurance rates or prevent us from securing coverage in the future. Additionally, if any such product liability claim or series of claims is brought against us for uninsured liabilities or is in excess of our insurance coverage, our business could be harmed.

The adoption of healthcare reform in the United States may harm our business, results of operations and/or financial condition.

The United States has recently made significant reforms to the U.S. healthcare system, and further reforms are still under consideration in Congress. These reforms include provisions that, among other things, may impose new and/or increased taxes and reduce and/or limit Medicare reimbursement. In particular, the law signed by President Obama on March 23, 2010 requires the medical device industry to subsidize healthcare reform in the form of a substantial annual excise tax on medical device sales commencing in 2013. We cannot predict what healthcare initiatives will be finally implemented. Many of the proposed reforms could reduce medical procedure volumes, impact the demand for our products or the prices at which we sell our products, and/or increase our cost of doing business.

We rely on our independent distributors to market and sell our products in select markets outside of the United States and Canada.

Sales of our products through independent distributors represented 8% of our net sales for the year ended December 31, 2009. Our success in these markets depends largely upon marketing arrangements with distributors, in particular their sales and service expertise and relationships with their respective customers in the marketplace. Although we intend to replace some of these distributors with a direct sales force, this will take time and we may maintain a distribution model in some markets. We do not control our distributors and they may not be successful in implementing our marketing plans.

Many of our distributors initially obtain and maintain foreign regulatory approval for sale of our products in their respective countries. We do not have long-term contracts with many of our distributors, and our distributors may terminate their relationships with us on little or no notice. In addition, some of our distributors are not required to purchase any minimum amount of products from us, may sell products that compete with ours or devote more efforts to selling other products, and may stop selling our products at any time. If we lose any of our significant distributors, if we fail to recruit and retain additional skilled distributors in these locations, or if our distributors devote more effort to selling products other than ours, our operations could be harmed. We have experienced turnover with some of our distributors in the past that has impacted our short-term financial results while we transitioned to new distributors. Similar occurrences could happen in the future.

We may not maintain positive cash flow from operations and, as a result, we may require additional capital. Failure to attract additional capital on acceptable terms could impair our growth.

We may require additional capital to execute our strategies and further expand our business. In particular, we depend on access to capital to acquire products and technologies that complement our existing product lines. If our cash reserves, together with cash available under our credit facility and cash generated internally, are insufficient to fund our operations or our capital requirements, we will require additional debt or equity financing. Equity financing, if available, may be dilutive to our stockholders. If we raise additional capital through the issuance of debt, this debt will be senior to our outstanding shares of capital stock upon our liquidation. The availability of such financing depends in large measure on capital markets and liquidity factors over which we can exert little control. Financing may not be available or, if available, may not be available on terms satisfactory to us and could result in significant stockholder dilution. In addition, covenants in debt financing arrangements may restrict our ability to operate our business or obtain additional debt financing. These covenants may also require us to attain certain levels of financial performance and we may not be able to do so; any such failure may result in the acceleration of such debt and the foreclosure by our creditors on the collateral we used to secure the debt. We may also elect to raise additional funds through collaboration, licensing, marketing, or similar arrangements, and these arrangements may require us to relinquish valuable rights to our products or proprietary technologies, or grant licenses that are not favorable to us. If we fail to obtain sufficient additional capital in the future, we could be forced to curtail our growth strategy by reducing or delaying capital expenditures and acquisitions, delaying or postponing our product development efforts (including clinical studies), selling assets, restructuring our operations, or refinancing our indebtedness.

Our assumptions about the market for our products may not be correct.

We are focused on the market for devices used to treat peripheral vascular disease. We believe that demographic trends point towards an increase in the need for our products. However, the projected demand for our products could materially differ from actual demand if our assumptions regarding these trends and acceptance of our products by the medical community prove to be incorrect or do not materialize or if drug therapies gain more widespread acceptance as a viable alternative treatment, which in each case could adversely affect our business prospects and profitability.

From time to time we may become subject to tax audits or similar proceedings, and as a result we may owe additional taxes, interest, and penalties in amounts that may be material.

We are subject to income taxes in many countries, jurisdictions, and provinces, including the United States. In determining our global provision for income taxes, we are required to exercise judgment. Regularly, we make estimates where the ultimate tax determination is uncertain. While we believe our estimates are reasonable, we cannot assure you that the final determination of any tax audit or tax-related litigation will not be materially different from that reflected in our historical income tax provisions and accruals.

In addition, we are subject to sales, use, and similar taxes in many countries, jurisdictions, and provinces, including those states in the United States where we maintain a physical presence or have a substantial nexus.

These taxing regimes are complex. For example, in the United States, each state and local taxing authority has its own interpretation of what constitutes a sufficient physical presence or nexus to require the collection and remittance of these taxes. Similarly, each state and local taxing authority has its own rules regarding the applicability of sales tax by customer or product type. We employ a variety of strategies from time to time with respect to our international operations. There can be no assurance that these strategies will be accepted by the relevant taxing authorities.

We have reviewed the tax positions taken, or to be taken, in its tax returns for all tax years currently open to examination by a taxing authority. As of December 31, 2009, the total amount of unrecognized tax benefits, that is the aggregate tax effect of differences between tax return positions and the benefits recognized in our financial statements, was approximately $299,000. The assessment of additional taxes, interest, and penalties as a result of audits, litigation, or otherwise, could be materially adverse to our current and future results of operations and financial condition.

Risks Related to the Regulatory Environment

Our business is subject to complex, costly, and burdensome regulations. We could be subject to significant penalties if we fail to comply.

The production and marketing of our products and our ongoing research and development and clinical trial activities are subject to extensive regulation and review by numerous governmental authorities both in the United States and abroad. U.S. and foreign regulations applicable to medical devices are wide-ranging and govern, among other things, the testing, marketing, and premarket clearance or approval of new medical devices, in addition to regulating manufacturing practices, reporting, promotion and advertising, importing and exporting, labeling, and record-keeping procedures.

Our failure to comply with applicable regulatory requirements could result in governmental agencies or a court taking action, including any of the following:

•

issuing public warning letters to us;

•

imposing fines and penalties on us;

•

issuing an injunction preventing us from manufacturing or selling our products;

•

bringing civil or criminal charges against us;

•

delaying the introduction of our new products into the market;

•

ordering a recall of, or detaining or seizing, our products; or

•

withdrawing or denying approvals or clearances for our products.

If any or all of the foregoing were to occur, our business, results of operations, and reputation could suffer.

If we are not successful in obtaining and maintaining clearances and approvals from governmental agencies, we will not be able to sell our products, and our future growth will be significantly hampered.

Our products require premarket clearance or approval in the United States and the CE Mark or other approvals in foreign countries where they are sold. Each medical device that we wish to market in the United States generally must receive either 510(k) clearance, unless it is exempt, or approval of a premarket application, or PMA, from the FDA before the product can be marketed or sold. Either process can be lengthy and expensive. The FDA’s 510(k) clearance procedure usually takes from three to twelve months from the date the FDA receives the application, but may take significantly longer. Although 510(k) clearances have been obtained for all of our current products that require clearances, these clearances may be revoked by the FDA if safety or

effectiveness problems develop with the devices. Our new products or significantly modified marketed products could be denied 510(k) clearance and required to undergo the more burdensome PMA approval process if they are not found to be substantially equivalent.

The PMA approval process is much more costly, lengthy, and uncertain than the premarket notification process. It generally takes from six months to three years from the date the application is submitted to, and filed with, the FDA, and may take even longer. Achieving premarket approval typically requires extensive clinical trials and may require the filing of numerous amendments with the FDA over time. We do not have significant experience in obtaining PMA approval for our products.

Our TAArget and UniFit products must receive PMA approval before being commercially distributed in the United States. To successfully obtain PMA approval of our TAArget and UniFit devices and other devices that we may develop or acquire that are not approved for sale in the United States, we may need to develop greater regulatory and clinical study expertise than we currently possess. Our inexperience in these areas may cause significant delays in or otherwise harm our ability to successfully complete the complex undertaking of obtaining regulatory approval for these devices. We continue to evaluate the potential financial benefits and costs of our clinical studies and the products being evaluated in them. If we determine that the costs associated with obtaining regulatory approval of a product exceed the potential financial benefits of that product, or if the projected development timeline is inconsistent with our investment horizon, we may choose to discontinue a clinical study and/or the development of a product. We cannot assure you that we will ever obtain PMA approval for our TAArget or UniFit devices or any other devices that we attempt to bring to market in the United States.

In May 2008, we submitted an investigational device exemption (IDE) application to the FDA to begin a feasibility study of our TAArget Thoracic Stent Graft, which we call the ENTRUST Trial. On December 4, 2009, we received conditional approval from the FDA to commence the ENTRUST Trial, provided that we resolve the issues identified in the conditional approval letter to the FDA’s satisfaction. We intend to work with the FDA to resolve these issues, although there can be no assurance that the FDA will unconditionally approve the IDE application.

In May 2007, we commenced a pivotal trial of the UniFit Abdominal Stent Graft, which we refer to as the UNITE Trial, and as of March 25, 2010, we had enrolled 54 patients in the trial. We plan to enroll 90 patients at 22 institutions. If the institutions participating in any of our clinical studies or trials do not enroll a sufficient number of patients to provide the clinical data necessary to obtain regulatory approval of the device being evaluated, or do not enroll patients in a timely fashion, the approval or clearance of that device for sale may be prevented or delayed.

The U.S. government is currently evaluating potential modifications to the FDA’s 510(k) clearance procedure. We cannot predict the outcome of this evaluation process, but it is possible that modifications, if adopted, could reduce the availability of the 510(k) clearance procedure, or make it more costly, lengthy or uncertain than the current procedure.

Our ability to market our products outside the United States is also subject to regulatory approval, including our ability to demonstrate the safety and effectiveness of our products in the clinical setting. The products for which we are currently conducting studies are already approved for sale outside of the United States. While our studies are ongoing, unfavorable data may arise in connection with usage of our products outside the United States, which could adversely impact approval of our products in the United States. Conversely, unfavorable data from clinical studies in the United States may adversely impact sales of our products outside the United States.

Even if regulatory approval or clearance of a product is granted, the approval or clearance could limit the uses or the claims for which the product may be labeled and promoted, which may limit the market for our products. If we do not obtain and maintain foreign regulatory or FDA approval with respect to our products, as applicable, we will not be able to sell our products, and our future growth will be significantly hampered.

Modifications to our marketed devices may require new regulatory clearances or premarket approvals, or may require us to cease marketing or recall the modified devices until clearances or approvals are obtained.

Any modification to a 510(k)-cleared device that could significantly affect its safety or effectiveness, or would constitute a major change in its intended use, requires the submission of another 510(k) or PMA application to address the change. The FDA requires every manufacturer to make its own determination as to whether a modification requires a new 510(k) clearance or PMA. Although in the first instance we may determine that a change does not rise to a level of significance that would require us to make a submission, the FDA may review and disagree with our determination and can require us to submit a 510(k) or a PMA for a significant technological change or major change or modification in intended use. If the FDA requires us to submit a 510(k) or a PMA for any modification to a previously cleared device, we may be required to cease marketing the device, recall it, and not resume marketing until we obtain clearance or approval from the FDA for the modified version of the device. Delays in our receipt of regulatory clearance or approval will cause delays in our ability to sell our products, which could have a negative effect on our business, results of operations, and prospects. Also, we may be subject to regulatory fines, penalties, and/or other sanctions authorized by the Federal Food, Drug, and Cosmetic Act.

If we or some of our suppliers fail to comply with the FDA’s Quality System Regulation and other applicable postmarket requirements, our manufacturing operations could be disrupted, our product sales and profitability could suffer, and we may become subject to a wide variety of FDA enforcement actions.

After a device is placed on the market, numerous regulatory requirements apply. We are subject to inspection and marketing surveillance by the FDA to determine our compliance with all regulatory requirements. If the FDA finds that we have failed to comply with any regulatory requirements, it can institute a wide variety of enforcement actions.

We and some of our suppliers must comply with the FDA’s Quality System Regulation, which governs the methods used in, and the facilities and controls used for, the design, testing, manufacture, control, quality assurance, installation, servicing, labeling, packaging, storage, and shipping of medical devices. The FDA enforces the Quality System Regulation through unannounced inspections. We have been, and anticipate in the future being, subject to such inspections. If we or one of our suppliers fails a Quality System Regulation inspection, or if a corrective action plan adopted by us or one of our suppliers is not sufficient, the FDA may bring an enforcement action against us, and our operations could be disrupted and our manufacturing delayed.

We are also subject to the FDA’s general prohibition against promoting our products for unapproved or off-label uses and to the medical device reporting, or MDR, regulations that require us to report to the FDA if our products may have caused or contributed to a death or serious injury, or if our device malfunctions and a recurrence of the malfunction would likely result in a death or serious injury. We must also file reports with the FDA of some device corrections and removals, and we must adhere to the FDA’s rules on labeling and promotion. If we fail to comply with these or other FDA requirements or fail to take adequate corrective action in response to any significant compliance issue raised by the FDA, the FDA can take significant enforcement actions, which could harm our business, results of operations, and our reputation.

In addition, most other countries, such as Japan, require us to comply with manufacturing and quality assurance standards for medical devices that are similar to those in force in the United States before marketing and selling our products in those countries. If we fail to comply, we would lose our ability to market and sell our products in those foreign countries.

Even after receiving regulatory clearance or approval, our products may be subject to product recalls, which may harm our reputation and divert managerial and financial resources.

The FDA and similar governmental authorities in other countries have the authority to order mandatory recall of our products or order their removal from the market if the governmental entity finds that our products would cause serious adverse health consequences or death. A government mandated or voluntary recall by us could occur as a result of component failures, manufacturing errors or design defects, including labeling defects. For example, we initiated a voluntary recall of our LeverEdge Contrast Injector in April 2007 due to a packaging flaw that compromised the sterility of the product. Any future recall of our products may harm our reputation with customers and divert managerial and financial resources.

If we do not comply with foreign regulatory requirements to market our products outside the United States, our business will be harmed.

Sales of medical devices outside the United States are subject to international regulatory requirements that vary from country to country. These requirements and the amount of time required for approval may differ from our experiences with the FDA in the United States. In some cases, we rely on our non-U.S. distributors to obtain premarket approvals, complete product registrations, comply with clinical trial requirements, and complete those steps that are customarily taken in the applicable jurisdictions to comply with governmental and quasi-governmental regulation. In the future, we expect to continue to rely on distributors in this manner in those countries where we continue to market and sell our products through them. Failure to satisfy these foreign regulations would impact our ability to sell our products in these countries and could cause our business to suffer. There can be no assurance that we will be able to obtain or maintain the required regulatory approvals in these countries.

Our products are regulated in the European Union under the European Medical Devices Directive (93/42/EEC). In order to market our medical devices in the European Union, we are required to obtain CE mark certification, which denotes conformity to the essential requirements of the Medical Devices Directive.

We have received CE mark certification to sell nearly all of our products. However, there can be no assurance that we will be able to obtain a CE mark for new products in the future or for modifications to our existing products or in the manufacturing of our products, and obtaining a CE mark may involve a significant amount of time and expense, stringent clinical and preclinical testing, or modification of our products and could result in limitations being placed on the use of our products in order to obtain approval.

Maintaining a CE mark is contingent upon our continued compliance with applicable European medical device requirements, including limitations on advertising and promotion of medical devices and requirements governing the handling of adverse events. There can be no assurance that we will be successful in maintaining

the CE mark for any of our current products. In particular, adverse event reporting requirements in the European Union mandate that we report incidents which led or could have led to death or serious deterioration in health. Under certain circumstances, we could be required to initiate a recall or removal of our product from the market in order to address product deficiencies or malfunctions. Any recall of our products may harm our reputation with customers and divert managerial and financial resources.

Failure to receive or maintain approval would prohibit us from selling these products in member countries of the European Union, and would require significant delays in obtaining individual country approvals. If we do not receive or maintain these approvals, our business could be harmed.

Our manufacturing facilities are subject to periodic inspection by European regulatory authorities and Notified Bodies, and we must demonstrate compliance with the Medical Devices Directive. Any failure by us to comply with European requirements in this regard may entail our taking corrective action, such as modification of our policies and procedures. In addition, we may be required to cease all or part of our operations for some period of time until we can demonstrate that appropriate steps have been taken. There can be no assurance that we will be found in compliance with such standards in future audits.

In Japan, the Ministry of Health, Labor and Welfare (the MHLW) regulates medical devices through the Pharmaceutical Affairs Law, which was reformed effective April 1, 2005. The revisions to Japanese regulations have resulted in longer lead times for product development.

Any such delay in product registrations could have a negative impact on our results of operations.

If we fail to comply with healthcare regulations, we could face substantial penalties and our business, operations, and financial condition could be adversely affected.

While we do not control referrals of healthcare services, and we do not receive payments directly from Medicare, Medicaid, or other third-party payors, healthcare laws and regulations apply broadly and may apply to our business. We could be subject to healthcare fraud and patient privacy regulation by the federal government and the states and international jurisdictions in which we conduct our business. The regulations that may affect our ability to operate include:

•

the federal healthcare program’s Anti-Kickback Statute, which constrains, among other things, our marketing practices, educational programs, pricing and discounting policies, and relationships with healthcare providers by prohibiting persons from soliciting, receiving, or providing remuneration, directly or indirectly, to induce either the referral of an individual, for an item or service or the purchasing, recommending, furnishing, or arranging for an item or service, for which payment may be made under a federal healthcare program such as the Medicare or Medicaid programs;

•

federal false claims laws which prohibit, among other things, individuals or entities from knowingly presenting, or causing to be presented, claims for payment from Medicare, Medicaid, or other third-party payors that are false or fraudulent, and which may apply to entities like us, because we provide coding and billing advice to customers;

•

the federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, which prohibits executing a scheme to defraud any healthcare benefit program or making false statements relating to health care matters and which also imposes regulatory and contractual requirements relating to the privacy, security, and transmission of individually identifiable health information;

•

state laws analogous to each of the above federal laws, such as anti-kickback and false claims laws that may apply to items or services reimbursed by non-governmental third-party payors, including commercial insurers, state laws that regulate, and in many cases restrict, medical device sales and marketing practices, and state laws governing the privacy of health information in certain circumstances, many of which differ from each other in significant ways and often are not preempted by HIPAA, thus complicating compliance efforts;

•

federal physician self-referral prohibitions, such as The Ethics in Patient Referral Act of 1989, commonly referred to as the federal physician self-referral law or the Stark law, which under certain circumstances prohibit physicians from referring patients for services paid for by Medicare or Medicaid to any entity in which the physician or an immediate family member has an ownership, compensation, or other financial interest, unless a specific statutory or regulatory exception applies; and

•

international regulations similar in nature and scope to the above-referenced requirements, including the European Union directive on data privacy, which imposes restrictions on the collection, use, disclosure, and processing of personal data.

While we believe that our present and past operations are and have been compliant in all material respects with the laws and regulations described above, there can be no assurance that we will not be found to be, or found to have been, in violation of any of such laws or regulations and as a result we may be subject to penalties, including civil and criminal penalties, damages, fines, and the curtailment or restructuring of our operations. Any penalties, damages, fines, or curtailment or restructuring of our operations could impair our ability to operate our business and our financial results. The risk of our being found in violation of these laws or regulations is increased by the fact that many of them have not been fully interpreted by the regulatory authorities or the courts, and their provisions are open to a variety of interpretations. Any action against us for violation of these laws or regulations, even if we successfully defend against them, could cause us to incur significant legal expenses and divert our management’s attention from the operation of our business.

Compliance with environmental laws and regulations could be expensive. Failure to comply with environmental laws and regulations could subject us to significant liability.

Our manufacturing operations and our research and development programs involve the use of hazardous substances and are subject to a variety of federal, state, and local environmental laws and regulations relating to the storage, use, discharge, disposal, and remediation of, and human exposure to, hazardous substances. Our research and development and manufacturing operations produce biological waste materials, such as human and animal tissue, and waste solvents, such as isopropyl alcohol. Regulatory authorities permit these operations, and the resulting waste materials are disposed of in material compliance with environmental laws and regulations. Compliance with these laws and regulations is expensive, and non-compliance could result in substantial liabilities, which could exceed our insurance coverage. In addition, our manufacturing operations may result in the release, discharge, emission, or disposal of hazardous substances that could cause us to incur substantial liabilities, including costs for investigation and remediation.

We cannot assure you that violations of these laws and regulations will not occur in the future or have not occurred in the past as a result of human error, accidents, equipment failure, or other causes. The expense associated with environmental regulation and remediation could harm our financial condition and operating results.

Inadequate levels of reimbursement from governmental or other third-party payors for procedures using our products may cause our net sales to decline.

Sales of our products depend in part on the reimbursement by governmental and private healthcare payors to our hospital and physician customers or their patients for the purchase and use of our products. In the United States, healthcare providers that purchase our products generally rely on third-party payors, principally federal Medicare, state Medicaid, and private health insurance plans, to pay for all or a portion of the cost of procedures. Any delays in obtaining, or an inability to obtain, payor coverage and reimbursement for our products or the services in which our products are used may cause our net sales to decline. In addition, if the reimbursement policies of domestic or foreign governmental or private healthcare payors change, our customers would likely change their purchasing patterns or the frequency of their purchases of the affected products.

Changes in healthcare systems in the United States or elsewhere could adversely affect the demand for our products, as well as the way we conduct business. Third-party payors have adopted, and are continuing to adopt, a number of healthcare policies intended to curb rising healthcare costs. These policies include:

•

controls on government-funded reimbursement for healthcare services and price controls on medical products and services providers;

•

limitations on coverage and reimbursement for new medical technologies and procedures; and

•

the introduction of managed care or prospective payment systems in which healthcare providers contract to provide comprehensive healthcare for a fixed reimbursement amount per person or per procedure.

We are unable to predict whether federal, state, or local healthcare reform legislation or regulations, or private payor policies, affecting our business may be proposed or enacted in the future, or what effect any such legislation, regulations, or policies would have on our business. Any such legislation, regulations, or policies that affect the coverage and reimbursement of our current or future products, or the procedures utilizing our current or future products, could cause our net sales to decline.

Outside of the United States, reimbursement systems vary significantly by country. Many foreign markets have government-managed healthcare systems that govern reimbursement for new devices and procedures. In most markets, there are private insurance systems as well as government-managed systems. Additionally, some foreign reimbursement systems provide for limited payments within a given period. These systems are subject to the same pressures to curb rising healthcare costs and control healthcare expenditures as those in the United States. For example, the government of Japan recently announced reductions in medical device reimbursement effective as of April 1, 2010. If adequate levels of reimbursement from third-party payors outside of the United States are not obtained, sales of our products outside of the United States may decrease and we may fail to achieve or maintain significant non-U.S. sales. For example, our TAArget and UniFit stent graft do not have approved reimbursement codes in France, and, as a result, many hospital customers are unable or unwilling to purchase such products. Although we are seeking to obtain the appropriate reimbursement codes, there can be no assurance that we will be successful in doing so in timely fashion or at all, and, if we are not successful our ability to grow our stent graft sales in this market would be impaired.

Risks Related to Intellectual Property

If we fail to adequately protect our intellectual property rights, or prevent use of our intellectual property by third parties, we could lose a significant competitive advantage and our business may suffer.

Our success depends in part on obtaining, maintaining, and enforcing our patents, trademarks, and other proprietary rights, and our ability to avoid infringing on the proprietary rights of others. We take precautionary steps to protect our technological advantages and intellectual property. We rely upon patent, trade secret, copyright, know-how, and trademark laws, as well as license agreements and contractual provisions, to establish our intellectual property rights and protect our products. These measures may only afford limited protection and may not:

•

prevent our competitors from duplicating our products;

•

prevent our competitors from gaining access to our proprietary information and technology; or

•

permit us to gain or maintain a competitive advantage.

The issuance of a patent is not conclusive as to its validity or enforceability. Any patents we have obtained or will obtain in the future might also be invalidated or circumvented by third parties. In addition, our pending patent applications may not issue as patents or, if issued, may not provide commercially meaningful protection, as competitors may be able to design around our patents to produce alternative, non-infringing designs. Should

such challenges to our patents be successful, competitors might be able to market products and use manufacturing processes that are substantially similar to ours. Additionally, we may not be able to effectively protect our rights in unpatented technology, trade secrets, and confidential information. We have a policy of requiring key employees and consultants and corporate partners with access to trade secrets or other confidential information to execute confidentiality agreements. Our confidentiality agreements also require our employees to assign to us all rights to any inventions made or conceived during their employment with us. We also generally require our consultants to assign to us any inventions made during the course of their engagement by us. There can be no assurance, however, that these agreements will provide meaningful protection or adequate remedies for us in the event of unauthorized use, transfer, or disclosure of confidential information or inventions.

In addition, the laws of foreign countries may not protect our intellectual property rights effectively or to the same extent as the laws of the United States. If our intellectual property rights are not adequately protected, we may not be able to commercialize our technologies, products, or services and our competitors could commercialize similar technologies, which could result in a decrease in our sales and market share.

If third parties claim that we infringe upon their intellectual property rights, we may incur liabilities and costs, and we may have to redesign or discontinue selling the affected product.

The medical device industry is litigious with respect to patents and other intellectual property rights. Companies operating in our industry routinely seek patent protection for their product designs, and many of our principal competitors have large patent portfolios. Companies in the medical device industry have used intellectual property litigation to gain a competitive advantage. Whether a product infringes a patent involves complex legal and factual issues, the determination of which is often uncertain. We face the risk of claims that we have infringed on third parties’ intellectual property rights, and we cannot assure you that our products or methods do not infringe the patents or other intellectual property rights of third parties. Prior to launching major new products in our key markets, we typically evaluate existing intellectual property rights. However, our competitors may also have filed for patent protection that is not as yet a matter of public knowledge or claim trademark rights that have not been revealed through our availability searches. Our efforts to identify and avoid infringing on third parties’ intellectual property rights may not always be successful. Any claims of patent or other intellectual property infringement, even those without merit, could:

•

be expensive and time consuming to defend;

•

result in us being required to pay significant damages to third parties for past use of the asserted intellectual property;

•

harm our reputation;

•

cause us to cease making or selling products that incorporate the challenged intellectual property;

•

require us to redesign, reengineer, or rebrand our products, which may not be possible and could be costly and time consuming if it is possible to do so at all;

•

require us to enter into royalty or licensing agreements in order to obtain the right to use a third party’s intellectual property, which agreements may not be available on terms acceptable to us or at all;

•

divert the attention of our management and key personnel from other tasks important to the success of our business; or

•

result in our customers or potential customers deferring or limiting their purchase or use of the affected products until resolution of the litigation.

It is also possible that one of our competitors could claim that our manufacturing process violates an existing patent. If we were unsuccessful in defending such a claim, we may be forced to stop production at one or more of our manufacturing facilities.

In addition, new patents obtained by our competitors could threaten a product’s continued life in the market even after it has already been introduced. If our business is successful, the possibility may increase that others will assert infringement claims against us.

In addition, we may become subject to interference proceedings conducted in the United States Patent Office or opposition proceedings conducted in foreign patent offices challenging the priority of invention or the validity of our patents. For example, in 2005 and 2006, respectively, Boston Scientific Corporation initiated opposition proceedings in the European Patent Office claiming that we were not the first to file a patent application on certain material. As a result of these opposition proceedings, some of our patent claims were canceled. Although the cancellation of these patent claims did not affect our ability to manufacture, distribute, or sell any of our products, it could affect our right to exclude others from selling products similar to our TAArget and UniFit stent grafts in Europe.

We may become involved in lawsuits and administrative proceedings to protect, defend, or enforce our patents that would be expensive and time consuming.

In order to protect or enforce our patent rights, we may initiate patent litigation or interference or opposition proceedings against third parties in the United States or in foreign countries. The defense of intellectual property rights, including patent rights through lawsuits, interference, or opposition proceedings, and other legal and administrative proceedings can be costly and can divert our technical and management personnel from their normal responsibilities. Such costs increase our operating losses and reduce our resources available for development activities. An adverse determination of any litigation or defense proceedings could put one or more of our patents at risk of being invalidated or interpreted narrowly and could put our patent applications at risk of not issuing.

Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation. For example, during the course of this kind of litigation and despite protective orders entered by the court, confidential information may be inadvertently disclosed in the form of documents or testimony in connection with discovery requests, depositions, or study testimony. This disclosure could materially adversely affect our business and financial results.

If we fail to observe the terms of our agreements with third-party patent holders, we may lose the ability to manufacture, market, or sell some of our products.

Certain aspects of our products are the subject of patents held by third parties. We manufacture, market, and sell these products pursuant to license agreements with these third parties. These arrangements require us to pay royalties, typically determined as a percentage of our net sales for the underlying product. If we fail to make these payments or otherwise fail to observe the terms of these agreements, we may lose our ability to sell these products. For example, we manufacture, market, and sell our TAArget and UniFit stent grafts pursuant to a sublicense from Bard Peripheral Vascular, Inc., a subsidiary of C.R. Bard, Inc., to a U.S. patent covering aspects of ePTFE. Our arrangement with Bard may preclude us from assigning the sublicense to a third party, including in connection with the sale of more than 30% of our capital stock or all or substantially all of our assets, without the prior consent of Bard. The loss by us of our right to manufacture, market, and sell our TAArget and UniFit products would harm our business and results of operations.

Risks Related to Our Common Stock

Our stock price may be volatile, and your investment in our common stock could suffer a decline in value.

There has been significant volatility in the market price and trading volume of equity securities that is unrelated to the financial performance of the companies issuing the securities. These broad market fluctuations may negatively affect the market price of our common stock. You may not be able to resell your shares at or above the price at which you purchased them due to fluctuations in the market price of our common stock caused by changes in our operating performance or prospects, a low volume of trading in our common stock, and other factors.

Some specific factors that may have a significant effect on our common stock market price include:

•

actual or anticipated fluctuations in our operating results or future prospects;

•

our announcements or our competitors’ announcements of new products;

•

public concern as to the safety or efficacy of our products;

•

the public’s reaction to our press releases, our other public announcements, and our filings with the Securities and Exchange Commission;

•

strategic actions by us or our competitors, such as acquisitions or restructurings;

•

changes in our growth rates or our competitors’ growth rates;

•

developments regarding our patents or proprietary rights or those of our competitors;

•

our inability to raise additional capital;

•

changes in financial markets or general economic conditions, including those resulting from war, incidents of terrorism, and responses to such events;

•

new laws or regulations or new interpretations of existing laws or regulations applicable to our business;

•

changes in accounting standards, policies, guidance, interpretations, or principles;

•

sales of common stock by us or our directors, officers, or principal stockholders; and

•

changes in stock market analyst recommendations or earnings estimates regarding our common stock, other comparable companies, or our industry generally.

In the past, following periods of volatility in the market price of a company’s securities, securities class action litigation has often been instituted. A securities class action suit against us could result in substantial costs and divert our management’s attention and resources that would otherwise be used to benefit the future performance of our business.

Our directors, officers, and principal stockholders have significant voting power and may take actions that may not be in the best interests of our other stockholders.

Our directors, officers, and affiliated stockholders holding more than 5% of our common stock collectively control a majority of our outstanding common stock, assuming the exercise of all options held by such persons. As a result, these stockholders, if they act together, would be able to control the management and affairs of our company and most matters requiring stockholder approval, including the election of directors and approval of significant corporate transactions. This concentration of ownership may have the effect of delaying or preventing a change in control, might adversely affect the market price of our common stock, and may not be in the best interests of our other stockholders.

Future acquisitions that we make may be dilutive to our current stockholders.

We intend to pursue the acquisition of complementary products, technologies, or businesses, and in connection with these acquisitions we may use substantial portions of our available cash or make dilutive issuances of securities. In addition, an acquisition could impair our operating results by causing us to incur debt or requiring us to recognize acquisition expenses or amortize, depreciate, or impair acquired assets. This debt would be senior to our outstanding shares of capital stock upon our liquidation.

Our corporate documents and Delaware law contain provisions that could discourage, delay, or prevent a change in control of our company.

Provisions in our amended and restated certificate of incorporation and bylaws may have the effect of delaying or preventing a change of control or changes in our management. These provisions include the following:

•

the division of our board of directors into three classes;

•

the right of the board of directors to elect a director to fill a vacancy created by the expansion of the board of directors or due to the resignation or departure of an existing board member;

•

the prohibition of cumulative voting in the election of directors, which would otherwise allow less than a majority of stockholders to elect director candidates;

•

the requirement for the advance notice of nominations for election to the board of directors or for proposing matters that can be acted upon at a stockholders’ meeting;

•

the ability of our board of directors to alter our bylaws without obtaining stockholder approval;

•

the ability of the board of directors to issue, without stockholder approval, up to 5,000,000 shares of preferred stock with terms set by the board of directors, which rights could be senior to those of our common stock;

•

the elimination of the rights of stockholders to call a special meeting of stockholders and to take action by written consent in lieu of a meeting;

•

the required approval of at least 75% of the shares entitled to vote at an election of directors to adopt, amend or repeal our bylaws or repeal the provisions of our amended and restated certificate of incorporation regarding the election and removal of directors and the inability of stockholders to take action by written consent in lieu of a meeting; and

•

the required approval of at least 75% of the shares entitled to vote at an election of directors to remove directors with cause.

We are also subject to the anti-takeover provisions of Section 203 of the Delaware General Corporation Law. Under these provisions, if anyone becomes an “interested stockholder,” we may not enter into a “business combination” with that person for three years without special approval, which could discourage a third party from making a takeover offer and could delay or prevent a change of control. For purposes of Section 203, “interested stockholder” means, generally, someone owning 15% or more of our outstanding voting stock or an affiliate of ours that owned 15% or more of our outstanding voting stock during the past three years, subject to certain exceptions as described in Section 203.

Properties

Our principal worldwide executive, distribution, and manufacturing operations are located at a 27,098 square foot leased facility and a nearby 7,477 square foot leased facility, located in Burlington, Massachusetts. In addition, our international operations are headquartered at a 12,841 square foot leased facility located in Sulzbach, Germany, our AlboGraft manufacturing operations are located at a 16,146 square foot leased facility in Brindisi, Italy, and our Asian operations are located at a 2,140 square foot leased facility located in Tokyo, Japan.

On March 23, 2010, we entered into a new series of lease agreements that:

•

extend the lease of our 27,098 square foot Burlington facility until approximately 2017;

•

lease an adjacent 16,629 square foot facility in Burlington until approximately 2017, which after approximately 2.5 years will be expanded to 27,289 square feet; and

•

terminate the lease of our 7,477 square foot Burlington facility.

The leases for our Sulzbach, Brindisi, and Tokyo facilities expire in 2010, 2016, and 2010, respectively. Based on our current operating plan, we believe our current facilities are adequate.

Legal Proceedings

In the ordinary course of business, we are from time to time involved in lawsuits, claims, investigations, proceedings, and threats of litigation consisting of intellectual property, commercial and other matters. While the outcome of these proceedings and claims cannot be predicted with certainty, there are no matters, as of December 31, 2009, that, in the opinion of management, might have a material adverse effect on our financial position, results of operations or cash flows.

Recent Sales of Unregistered Securities

In October 2006, we completed our initial public offering of our common stock through a Registration Statement on Form S-1 (File No. 333-133532) that was declared effective by the SEC on October 18, 2006. We registered 6,325,000 shares of our common stock with a proposed aggregate offering price of $44.3 million. All of the shares of common stock issued pursuant to the registration statement were sold at a price to the public of $7.00 per share. The managing underwriters were Goldman Sachs & Co. Incorporated, CIBC World Markets Corp., Cowen and Company, LLC and Thomas Weisel Partners LLC.

In connection with our initial public offering, we sold 5,500,000 shares and raised aggregate net proceeds of approximately $35.8 million, after deducting underwriting discounts and commission of approximately $2.7 million and offering expenses of $3.0 million. As of December 31, 2009, we have spent the net proceeds as follows:

Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion should be read in conjunction with our consolidated financial statements and the related notes contained elsewhere in this Annual Report on Form 10-K and in our other Securities and Exchange Commission filings. The following discussion may contain predictions, estimates, and other forward-looking statements that involve a number of risks and uncertainties, including those discussed under “Risk Factors” and elsewhere in this Annual Report on Form 10-K. These risks could cause our actual results to differ materially from any future performance suggested below.

Overview

We are a medical device company that develops, manufactures, and markets medical devices and implants for the treatment of peripheral vascular disease. Our principal product offerings are sold throughout the world, primarily in the United States, the European Union and, to a lesser extent, Japan. We estimate that the annual worldwide market addressed by our 15 product lines approaches $1 billion and that the annual worldwide market for all peripheral vascular devices approximates $3 billion. We have used acquisitions as a primary means of further accessing the larger peripheral vascular device market, and we expect to continue to pursue this strategy in the future. We currently manufacture most of our product lines in our Burlington, Massachusetts, headquarters.

Our products are used by vascular surgeons who treat peripheral vascular disease through both open surgical methods and more recently adopted endovascular techniques. In contrast to interventional cardiologists and interventional radiologists, neither of whom are certified to perform open surgical procedures, vascular surgeons can perform both open surgical and minimally invasive endovascular procedures, and are therefore uniquely positioned to provide patients with a wider range of treatment options.

Below is a listing of our product lines and product categories:

•

Our Endovascular product category includes our TAArget Thoracic Stent Graft, UniFit Abdominal Stent Graft, VascuTape Radiopaque Tape, LeverEdge Contrast Injector, and The UnBalloon Non-Occlusive Modeling Catheter. We also report the results of our distribution of the Endologix Powerlink System within this category.

•

Our Vascular product category includes our Expandable LeMaitre Valvulotome, Pruitt-Inahara and Pruitt F3 Carotid Shunts, InvisiGrip Vein Stripper, LeMaitre Balloon Catheters, and the five remote endarterectomy products, AnastoClip Vessel Closure System, and the AlboGraft Vascular Graft. We also report the results of our distribution of the XenoSure Biologic Vascular Patch within this category.

•

Our General Surgery product category includes our Reddick Cholangiogram Catheter and related accessories and OptiLock Implantable Port.

For the 2007, 2008 and 2009 fiscal years, we reported the net sales of our AnastoClip Vessel Closure System within the Endovascular product category, and our discussion herein maintains this presentation. Commencing in 2010 we will report these net sales in the Vascular category.

We evaluate the sales performance of our various product lines utilizing criteria that vary based upon the position of each product line in its expected life cycle. For established products, we typically review unit sales and selling prices. For faster growing products, we typically also focus upon new account generation and customer retention.

Our business opportunities include the following:

•

the addition of complementary products through acquisition;

•

the updating of existing products and introduction of new products through research and development;

•

the long-term growth of our sales force in North America, Europe and Japan; and

•

the introduction of our products in new markets upon obtainment of regulatory approvals in these markets.

We are currently pursuing each of these opportunities.

To assist us in evaluating our business strategies, we regularly monitor long-term technology trends in the peripheral vascular device market. Additionally, we consider the information obtained from discussions with the medical community in connection with the demand for our products, including potential new product launches. We also use this information to help determine our competitive position in the peripheral vascular device market and our manufacturing capacity requirements.

We sell our products primarily through a direct sales force. As of December 31, 2009, our sales force was comprised of 61 sales representatives in North America, the European Union and Japan. We also sell our products through a network of distributors in various countries outside of the United States and Canada. Our worldwide headquarters are located in Burlington, Massachusetts. Our international operations are headquartered in Sulzbach, Germany. We also have sales offices located in Tokyo, Japan, and Rome, Italy, and a manufacturing facility in Brindisi, Italy. In 2009, approximately 92% of our net sales were generated in markets in which we employ direct sales representatives.

Because we believe that direct-to-hospital sales engender closer customer relationships, and allow for higher selling prices and gross margins, we periodically enter into transactions with our distributors to transition their sales of our medical devices to our direct sales organization. In March 2009, we entered into a definitive agreement with Edwards Lifesciences to terminate its distribution of our AlboGraft Vascular Graft. We paid $3.5 million to Edward Lifesciences in exchange for this early termination, the purchase of their AlboGraft customer list, certain customer contracts and remaining AlboGraft inventory, and their provision of sales and marketing services.

Fluctuations in the rate of exchange between the U.S. dollar and foreign currencies, primarily the euro, affect our financial results. For the year ended December 31, 2009, approximately 42% of our sales were denominated in foreign currencies. We expect that foreign currencies will continue to represent a similarly significant percentage of our sales in the future. Selling, marketing, and administrative costs related to these sales are largely denominated in the same respective currency, thereby partially mitigating our transaction risk exposure. We therefore believe that the risk of a significant impact on our operating income from foreign currency fluctuations is moderated. However, most of our foreign sales are denominated in local currency, and if there is an increase in the rate at which a foreign currency is exchanged for U.S. dollars, it will require more of

the foreign currency to equal a specified amount of U.S. dollars than before the rate increase. In such cases we will receive less in U.S. dollars than we did before the rate increase went into effect.

Our strategy for growing our business includes the acquisition of complementary product lines and companies and occasionally the discontinuance or divestiture of products or activities that are no longer complementary. These actions may affect the comparability of our financial results from period to period and may cause substantial fluctuations period to period. For example, in December 2008 we entered into an agreement with Neovasc Inc. to distribute the XenoSure Biologic Vascular Patch. We began selling this product in 2009.

The following table indicates the impact of foreign currency fluctuations and changes to our business activities for each of our quarters during the three most recently completed fiscal years:

In recent years we have experienced comparatively greater success in product markets characterized by low or limited competition. In these markets, we believe that we have been able to increase selling prices without sacrificing material market share, to the benefit of our rate of net sales growth. In contrast, we have experienced comparatively lesser success in highly competitive product markets such as aortic stent grafts, where we face intense competition from larger companies with greater resources. For example, we believe that intense competition from Medtronic, W. L. Gore and Cook has affected the adoption of our TAArget Thoracic Stent Graft in European markets. While this latter trend may moderate as we continue to grow our organization, and while we believe that this trend can be mitigated by our strong relationships with our vascular surgeon customers, there can be no assurance that we will be successful in the aortic stent graft market or in other highly competitive markets.

Net Sales and Expense Components

The following is a description of the primary components of our net sales and expenses:

Net sales. We derive our net sales from the sale of our products, less discounts and returns. Most of our sales are generated by our direct sales force and are shipped and billed to hospitals or clinics throughout the world. In countries where we do not have a direct sales force, sales are primarily generated by shipments to distributors who, in turn, sell to hospitals and clinics. In those cases where our products are held on consignment at a hospital or clinic, we generate sales at the time the product is used in surgery rather than at shipment.

Cost of sales. We manufacture nearly all of the products that we sell. Our cost of sales consists primarily of manufacturing personnel, raw materials and components, depreciation of property and equipment, and other allocated manufacturing overhead, as well as freight expense we pay to ship products to customers.

Sales and marketing. Our selling and marketing expense consists primarily of salaries, commissions, stock based compensation, travel and entertainment, attendance at medical society meetings, training programs, advertising and product promotions, direct mail, and other marketing costs.

General and administrative. General and administrative expense consists primarily of executive, finance and human resource expense, stock based compensation, legal and accounting fees, information technology expense, intangible amortization expense, and insurance expense.

Research and development. Research and development expense includes costs associated with the design, development, testing, enhancement, and regulatory approval of our products. It also includes costs associated with design and execution of clinical studies and regulatory submissions and costs to register, maintain, and defend our intellectual property.

Restructuring. Restructuring expense includes costs directly associated with distribution agreement termination expenses, severance, and retention costs for terminated employees, and other expenses associated with restructuring our operations.

Other income (expense). Other income (expense) primarily includes interest income and expense, investment impairment charges, foreign currency gains (losses), and other miscellaneous gains (losses).

Income tax expense. We are subject to federal and state income taxes for earnings generated in the U.S., which include operating losses in certain foreign jurisdictions for certain years depending on tax elections made, and foreign taxes on earnings of our wholly-owned German, French, Italian, and Japanese subsidiaries. Our consolidated tax expense is affected by the mix of our taxable income (loss) in the United States, Germany, France, Italy, and Japan, permanent items, discrete items, unrecognized tax benefits, and amortization of goodwill for U.S tax reporting purposes.

Total	$	50,908	$	48,720	4	%

Net sales. Net sales increased 4% to $50.9 million in 2009 from $48.7 million in 2008. Sales in our Vascular product category grew 11%, while sales in our Endovascular product category and General Surgery product categories decreased by 7% and 2%, respectively, from the previous year. New acquisitions and business development activities added 2% to year-over-year sales growth while changes in foreign currency exchange rates subtracted 2%. Excluding these effects, net sales for 2009 grew 4%. Sales increases in 2009 were largely driven by higher average selling prices across nearly all product lines, as well as an increase in our Vascular product category of $3.3 million which included additional XenoSure Biologic Vascular Patch sales of $1.1 million, increased valvulotomes sales of $0.7 million and vascular catheter sales of $0.5 million, as well as increases in all other product lines in the Vascular product category. These gains were partially offset by a $1.2 million decrease in our Endovascular product category, primarily due to decreased TAArget Thoracic Stent Graft, Endologix Powerlink System, and AnastoClip Vessel Closure System sales, as well as the effect of negative currency exchange rate fluctuations of $0.9 million. In 2009 the volatility of the euro as compared to the dollar significantly affected the value of our sales in Europe when translated into U.S. dollars. This affect may continue into 2010.

Our Endovascular product category declined to 29% of net sales in 2009 from 33% in the prior year. Our Endovascular product category represented 27% of our revenues for the three months ending December 31, 2009. Endovascular declines were driven in part by decreased sales from our TAArget thoracic and Endologix Powerlink stent graft offerings. TAArget stent graft results were due mainly to the retirement of our largest stent graft customer in the fourth quarter of 2009, as well as strong competitor product offerings. We expect that our Endovascular product category will continue to decrease as a percentage of our revenues in 2010, in part due to the loss of this key customer.

Direct-to-hospital net sales were 92% in 2009, up from 88% in 2008. The increase was largely due to strong results from our comparatively newer sales organizations in Italy and France and the termination of Edwards Lifesciences distribution of our AlboGraft Vascular Graft.

Net sales by geography. Net sales in the Americas increased $2.5 million to $29.4 million in 2009. The increase was mainly the result of higher average selling prices across nearly all product lines as well as the addition of $1.1 million of sales of the XenoSure Biologic Vascular Patch. International net sales decreased $0.3 million in 2009 to $21.5 million. International sales were favorably impacted by sales growth of $0.8 million at our Italian sales office, $0.5 million at our French sales office, and $0.3 million at our Japanese sales office. International sales were unfavorably impacted by the effect of negative currency exchange rate fluctuations of $0.9 million and by a decrease in sales of our Endovascular product category of $0.5 million.

International direct-to-hospital net sales increased to 83% in 2009, up from 73% in 2008. The increase was largely due to strong results from our comparatively newer sales organizations in Italy and France and the termination of Edwards’ distribution of our AlboGraft Vascular Graft.

Gross profit. Gross profit increased 10% to $37.3 million in 2009 from $33.9 million in 2008 while our gross margin increased 3.7% to 73.3%. The gross margin increase was largely the result of improved manufacturing efficiencies, higher average selling prices across nearly all product lines, a reduction in inventory write-downs related to the redesign of our TAArget Thoracic Stent Graft product line in 2008, and our

direct-to-hospital AlboGraft Vascular Graft transition in Europe which commenced on March 27, 2009. The increase was partially offset by negative currency exchange rate fluctuations.

Sales and marketing. Sales and marketing expense decreased 10% to $17.7 million in 2009, from $19.8 million in 2008. Selling expense decreased $1.6 million while marketing expense decreased $0.5 million. Foreign currency exchange rate fluctuations reduced sales and marketing expense by $0.3 million compared to the prior year. Selling expense decreases were driven largely by reduced sales commissions and payroll costs of $0.8 million, decreased travel and entertainment expenses of $0.4 million, and the effects of currency exchange rate fluctuations. Marketing expense decreases were largely the result of reduced advertising expenses of $0.2 million, reduced advisory board expenses of $0.2 million, and the effects of currency exchange rate fluctuations, and were partially offset by additional payroll costs of $0.2 million. As a percentage of revenues, sales and marketing expense decreased to 35% in 2009 from 41% in the prior year. At the end of 2009, we employed 61 field sales representatives worldwide, as compared to 52 at the end of 2008. Selling expense was restrained in part by the adoption of a lower-cost compensation model for most new sales hires, and we expect to continue this hiring practice in 2010.

General and administrative. General and administrative expense decreased 1% to $9.9 million in 2009 from $10.0 million in 2008. The decrease was primarily due to a reduction in insurance premiums of $0.2 million and was partially offset by increased amortization of $0.1 million related to the termination of our AlboGraft Vascular Graft distribution agreement.

Research and development. Research and development expense increased 11% to $5.9 million in 2009 from $5.3 million in 2008. As a percentage of revenues, research and development expense increased to 12% in 2009 compared to 11% in 2008. The increase was driven by increased regulatory and clinical affairs related costs of $0.7 million as well as higher product development expense of $0.1 million, and was partially offset by a reduction in royalty expense of $0.1 million, driven by reduced TAArget Thoracic Stent Graft and UniFit Abdominal Stent Graft sales, and in processing engineering expense of $0.1 million. We had enrolled 47 patients in our UNITE clinical trial as of December 31, 2009 compared to 22 as of December 31, 2008. We anticipate that research and development expense will increase over time as more UNITE and ENTRUST Trial patients are enrolled, new products follow the regulatory pathways, and more product development is undertaken.

Restructuring. Restructuring charges increased to $1.8 million in 2009 from $1.1 million in 2008. In 2009, we incurred a $1.8 million restructuring charge related to the March 27, 2009 termination of our AlboGraft Vascular Graft distribution agreement with Edwards Lifesciences. The transaction included the payment of $3.5 million in exchange for the termination of the distribution agreement, as well as the acquisition of detailed customer information, transition services, and remaining product inventory. 2008 charges included $0.7 million related to the early termination of our distributor in Italy, and $0.4 million related to our reductions in force in February and July.

Impairment charges. We incurred $0.1 million of impairment charges in 2009 related to patents deemed to have no value based on future expected economic benefits. We recorded an impairment charge of $0.6 million in 2008. The charge was the result of the write-down of intangible assets totaling $0.5 million relating to a customer relationship at our Biomateriali subsidiary, as well as the write-down of selected patents of $0.1 million.

Other income (expense). In 2009, net interest income was $12,000 compared to $0.5 million in 2008. The decrease was a result of an unfavorable interest rate market and the allocation of our portfolio to low risk investments. Foreign exchange gains for 2009 were $0.3 million compared to foreign exchange losses of $0.1 million in 2008. Foreign exchange gains are due to the comparative weakening of the dollar versus the euro during the financial period. Other income (expense) for 2009 was primarily due to losses on the disposal of capital equipment of $17,000. In 2008, we recognized the write-down of portfolio investments totaling $0.2 million which was attributed to the other-than-temporary decline in one specific asset backed security which we held as available-for-sale in our marketable securities portfolio

Income tax expense. We recorded a provision for taxes of $0.6 million in 2009 compared to $0.5 million in 2008 on pre-tax income of $2.2 million in 2009 and on a pre-tax loss of $2.8 million in 2008. The 2009 provision was comprised of taxes on profits on certain of our foreign subsidiaries that are profitable, deferred tax liabilities related to the amortization of goodwill for U.S. tax purposes which cannot be used to reduce existing deferred tax assets, and the alternative minimum tax. Our effective tax rate differed from the U.S. statutory tax rate principally due to the utilization of net operating loss carryforwards. While it is often difficult to predict the final outcome or timing of the resolution of any particular tax matter, we believe that our tax reserves reflect the probable outcome of known contingencies. In 2009, we utilized $4.8 million of our U.S net operating loss carryforwards. During 2010, we could utilize the remaining $1.8 million of U.S net operating loss carryforwards, which may result in an increased provision for taxes on a prospective basis.

We provide a full valuation allowance for net deferred tax assets, as we believe it is more likely than not that the future tax benefits from accumulated net operating losses and deferred taxes will not be realized. However, it is possible that the realization of future profits could result in the reversal of a significant portion, or all of the valuation allowance, which would then be recorded as a tax benefit in the consolidated statements of operations in the period of reversal.

Net sales. Net sales increased 18% to $48.7 million in 2008 from $41.4 million in 2007. Sales in our Endovascular product category increased by 13%, while sales in our Vascular and General Surgery product categories grew by 22% and 1%, respectively, over the previous year. New acquisitions and business development activities added 7% to year-over-year sales growth, changes in foreign currency exchange rates added 4% and organic sales increased 7%. Sales increases were driven in part by the inclusion of our 2007 acquisitions excluding the effects of currency exchange rate fluctuations of approximately $3.0 million, higher average selling prices, the favorable impact of foreign currency fluctuations of approximately $1.5 million, and significant sales growth in various international markets, including the United Kingdom, Japan and France, and were partially offset by a decline in unit sales in several of our product lines. Due to volatility of the euro as compared to the dollar in 2008 we experienced significant changes throughout the year in the value of our sales in Europe when translated into U.S. dollars.

Net sales by geography. Net sales in the United States and Canada increased 7% to $26.9 million in 2008, as compared to $25.1 million in 2007. The increase was driven primarily by the full-year inclusion of our 2007 acquisitions of the LeverEdge Contrast Injector, aSpire Stent, and EndoRE product lines, as well as higher average selling prices and strong results from our valvulotome and embolectomy catheter product lines. Net sales outside of the United States and Canada increased 34% to $21.8 million for 2008 compared to $16.3 million in 2007. The increase outside the United States and Canada was driven primarily by growth within our endovascular product category which includes our next generation TAArget and UniFit stent grafts, the Powerlink System, the inclusion of AlboGraft Vascular Graft sales to Edwards Lifesciences, the impact of foreign currency fluctuations of approximately $1.5 million and strong results from our French, Japanese and U.K. subsidiaries. Direct-to-hospital net sales represented 73% of the total net sales outside the United States and Canada in 2008, as compared to 74% in 2007.

*	Not a meaningful percentage relationship.

Gross profit. Gross profit increased 10% to $33.9 million in 2008 from $30.7 million in 2007. The gross profit increase was driven primarily by greater net sales, higher average selling prices across several product categories, and favorable foreign currency fluctuations for the full year. The improvement was partially offset by manufacturing inefficiencies at our Burlington manufacturing facility, the write-off of $1.0 million of excess and obsolete inventory largely related to product improvements related to our TAArget and UniFit stent grafts and our TT Tortuous Tracker Delivery System, and the inclusion of Biomateriali in our consolidated results. Gross profit in 2007 was negatively impacted by a $0.1 million inventory charge in December related to the Biomateriali acquisition. The total gross margin as a percentage of net sales was 69.6% in 2008, compared with 74.1% in 2007. The decrease from 2007 was largely a result of the inclusion of the AlboGraft sales in 2008, the write-off of $1.0 million of excess and obsolete inventory largely related to product improvements, and continued strength in our international business; partially offset by higher average selling prices across several product categories.

*	Not a meaningful percentage relationship.

Sales and marketing. Sales and marketing expense increased 2% to $19.8 million in 2008, from $19.4 million in 2007. The increase was driven primarily by the addition of our direct sales efforts in France and Italy, as well as foreign currency exchange rate fluctuations of $0.5 million, and largely offset by a decrease in the total number of sales and marketing professionals and associated management during 2008. At the end of 2008, we employed 52 field sales representatives and 11 sales managers worldwide, as compared to 57 and 17, respectively, at the end of 2007.

General and administrative. General and administrative expense increased 5% to $10.0 million in 2008 from $9.5 million in 2007. The increase was primarily due to the inclusion of Biomateriali in our consolidated results of $0.6 million, as well as the addition of our French and Italian direct sales efforts, which require local administrative support, and negative foreign currency exchange rate fluctuations of $0.1 million, and was partially offset by a decrease in the number of general and administrative personnel.

Research and development. Research and development expense increased 16% to $5.3 million in 2008 from $4.6 million in 2007. The increase was driven by increases in regulatory and clinical expense and personnel costs, the inclusion of Biomateriali in the consolidated results, increased royalties of $0.1 million, higher product development costs largely related to the introduction of the TT delivery system, and foreign currency exchange rate fluctuations of $0.1 million. These increases were partially offset by decreases in process development costs.

Restructuring. Restructuring charges increased to $1.1 million in 2008 from $1.0 million in 2007. 2008 charges included $0.7 million related to the early termination of our distributor in Italy, and $0.4 million related to our reductions in force in February and July. Expenses for 2007 included charges related to the buy-out of our distributors in Ireland and Italy due to our decision to sell directly to hospitals in those countries.

Purchased research and development. In conjunction with a technology acquisition in December 2007, we acquired in-process research and development with a fair value of $0.4 million that was expensed on the date of acquisition, as the acquired technology had not yet reached technological feasibility and had no alternative future use to us at the date of acquisition.

Impairment charges. We recorded an impairment charge of $0.6 million in 2008. The charge was the result of the write-down of intangible assets totaling $0.5 million relating to a customer relationship at our Biomateriali subsidiary, as well as the write-down of selected patents of $0.1 million.

Other income (expense). In 2008 interest income was $0.5 million compared to $1.3 million in 2007. The change was due to a decrease in average cash on hand throughout the year, significantly reduced yields on portfolio investments, the write-down of portfolio investments of $0.2 million which was attributed to the other-than-temporary decline in one specific asset backed security which we held as available-for-sale in our marketable securities portfolio at December 31, 2008, and increased interest expense associated with acquisition related debt at our Biomateriali subsidiary of $0.1 million. Losses on foreign currency exchange were due to a relative decrease in the strength of the euro as compared to the U.S. dollar. Other income (expense) for 2008 was primarily due to losses on the disposal of capital equipment of $41,000.

Income tax expense. We recorded a provision for taxes of $0.5 million in 2008 compared to $0.2 million in 2007 despite pre-tax losses of $2.8 million in 2008 and $2.7 million in 2007. The 2008 provision was the result of a number of factors, including taxes on profits on certain of our foreign subsidiaries that are profitable, deferred tax liabilities related to the amortization of goodwill for U.S. tax purposes, which cannot be used to reduce existing deferred tax assets, and effects of changes in uncertain tax positions.

Liquidity and Capital Resources

At December 31, 2009, our cash, cash equivalents and marketable securities were $24.0 million as compared to $21.3 million at December 31, 2008. Our cash and cash equivalents are highly liquid investments

with maturities of 90 days or less at the date of purchase and consist of time deposits, fully collateralized overnight repurchase agreements, and U.S. government obligations, and are stated at cost, which approximates fair value. Our marketable securities are primarily marketable debt securities, corporate bonds, and U.S. government securities that we classify as available-for-sale and are carried at fair market value. We did not hold any mortgage asset-backed or auction-rate securities in our investment portfolio as of December 31, 2009.

The majority of our marketable securities have remaining maturities of two years or less. The weighted average maturity of the portfolio was 1.5 months as of December 31, 2009, a reduction of 5.0 months from December 31, 2008. As of December 31, 2009, our investment portfolio included $0.4 million of asset-backed securities collateralized by credit card debt, and auto loans. In order to limit our credit risk exposure, we reduced our asset-backed securities holdings in 2009 by $1.2 million, from $1.6 million as of December 31, 2008. In the event of a temporary decline in market value, we have the intent and ability to hold our debt investments for a sufficient period of time to allow for recovery of the principal amounts invested. We continually monitor the asset allocation of our holdings in an attempt to mitigate our credit and interest rate exposures, and we intend to continue to closely monitor developments in the credit markets and make appropriate changes to our investment policy as necessary. Although the volatility in the current global financial markets can affect the liquidity and valuation of selected securities, we do not anticipate that these events will result in significant portfolio liquidity limitations or write-downs, although we can make no assurances to this effect.

Operating and Capital Expenditure Requirements

We require cash to pay our operating expenses, make capital expenditures, and pay our long-term liabilities. Since our inception, we have funded our operations through private and public placements of equity securities, short-term borrowings, and funds generated from our operations.

For the year ended December 31, 2009, we recognized operating income of $1.9 million, net of a $1.8 million restructuring charge. Although it is our intention to generate an operating profit on an ongoing basis, excluding the impact of acquisitions and distributor terminations, there can be no assurance that we will generate an operating profit in the future due to our continued investment in growing our business. We expect to fund any increased costs and expenditures from our existing cash and cash equivalents and marketable securities, though our future capital requirements depend on numerous factors. These factors include, but are not limited to, the following:

•

the revenues generated by sales of our products;

•

the costs associated with expanding our manufacturing, marketing, sales, and distribution efforts;

•

the earn-out payments due related to The UnBalloon Non-Occlusive Modeling Catheter;

•

the rate of progress and cost of our research and development activities;

•

litigation;

•

the costs of obtaining and maintaining FDA and other regulatory clearances of our products and products in development;

•

the effects of competing technological and market developments; and

•

the number, timing, and nature of acquisitions and other strategic transactions.

Our cash balances may decrease as we continue to use cash to fund our operations, make acquisitions, make purchases under our share repurchase program, and make deferred payments related to prior acquisitions. We believe that our cash, cash equivalents, investments and the interest we earn on these balances will be sufficient to meet our anticipated cash requirements for at least the next 12 months. If these sources of cash are insufficient to satisfy our liquidity requirements beyond the next 12 months, we may seek to sell additional equity or debt securities or borrow against our credit facility. The sale of additional equity and debt securities may result in

dilution to our stockholders. If we raise additional funds through the issuance of debt securities, such securities could have rights senior to those of our common stock and could contain covenants that would restrict our operations. We may require additional capital beyond our currently forecasted amounts. Any such required additional capital may not be available on reasonable terms, if at all. Insufficient funds may require us to delay, scale back, or eliminate some or all of our business operations or may adversely affect our ability to operate as a going concern.

Credit Facility

We have a revolving line of credit with Brown Brothers Harriman & Co under which our borrowing capacity is $10 million, with a maximum principal amount of any letters of credit issued as part of this facility of $3 million. In August 2009, the maturity date for amounts borrowed was extended to August 2011. Loans made under this revolving line of credit bear interest at LIBOR plus 200 basis points or the bank’s base rate, at our discretion. Borrowings under this line of credit are collateralized by substantially all of our assets. As of December 31, 2009, we had no borrowing outstanding under this line of credit. The loan agreement requires that we meet certain financial and operating covenants including a required leverage ratio and minimum tangible net worth. As of December 31, 2009, we were in compliance with these covenants.

Cash Flows


	Year ended December 31,						Net Change
	2009			2008			Net Change
Cash and cash equivalents	$	23,192		$	15,895		$	7,297

Cash flows provided by (used in):
Operating activities	$	5,440		$	581		$	4,563
Investing activities		2,182			9,013			(6,831	)
Financing activities		(376	)		(24	)		(352	)

Operating activities. Net cash provided by operating activities was $5.4 million in 2009 and consisted of the $1.6 million net income, adjusted for non-cash items of $3.4 million (including depreciation and amortization of $1.4 million, stock-based compensation of $1.0 million, provision for inventory write-offs of $0.4 million, provision for deferred income taxes of $0.2 million, an intangibles impairment charge of $0.1 million and $0.1 million in accounts receivable loss provisions) and net cash provided by changes in working capital of $0.4 million. The net cash provided by changes in working capital was principally the result of a reduction in prepaid assets and in inventories and was partially offset by increased accounts receivable.

Net cash provided by operating activities was $0.6 million in 2008 and consisted of a $3.3 million net loss adjusted for non-cash related items of $4.4 million (including depreciation and amortization of $1.6 million, provision for inventory write-offs of $1.0 million, stock-based compensation of $0.8 million, intangibles impairment charges of $0.6 million, investment impairment write-offs of $0.2 million, and a deferred income tax provision of $0.2 million, and was partially offset by the accretion of discounts on marketable securities of $0.1 million). Net cash used from changes in operating assets and liabilities was $0.6 million. The net cash used from changes in operating assets and liabilities was primarily a result of the payment of restructuring-related liabilities and an overall decrease in operating expense spending in 2008, offset by reduced levels inventory of $1.5 million.

Investing activities. Net cash provided by investing activities was $2.2 million in 2009. This was primarily due to sales and maturities of marketable securities of $4.6 million, the purchase of technology and other intangible assets of $1.0 million, payments made related to prior year acquisitions of $0.8 million, and purchases of property and equipment of $0.6 million.

Net cash provided by investing activities was $9.0 million in 2008. This was primarily due to sales and maturities of marketable securities of $14.9 million, and partially offset by purchases of marketable securities of $4.3 million, purchases of property and equipment of $0.6 million, payments made related to prior year acquisitions of $0.8 million, and the purchase of technology and other intangible assets of $0.1 million. The net proceeds from the sale and maturities of marketable securities of $10.6 million were reinvested into cash equivalents such as time deposits and fully collateralized overnight repurchase agreements.

In December 2007, we purchased certain patent applications and in-process research and development which included earn-out payments associated with the commercialization of the device in the European Union and the United States as part of the consideration. The earn-out payments are payable quarterly at approximately the rate of two times sales for the four quarters. The European earn-out period is measured from December 23, 2009 through December 22, 2010. We recorded an intangible asset and a liability of approximately $5,000 related to the 2009 sales volume. The United States earn-out period is measured over four quarters following the first commercial sale in the United States. We anticipate that the payment of resulting future earn-out obligations may impact cash flow from investing activities in 2010.

Financing activities. Net cash used in financing activities was $0.4 million in 2009. This was primarily due to the purchase of $0.5 million of treasury stock under our stock repurchase plan and the purchase of $0.2 million of treasury stock to cover withholding taxes of restricted stock award vesting’s and was partially offset by $0.2 million from the exercise of stock options and $0.1 million from an Italian government loan program which we assumed as part of our purchase of Biomateriali. We may purchase an additional $1.5 million of treasury stock under our stock repurchase plan through December 31, 2010.

Net cash used in financing activities was $24,000 in 2008. This was primarily due to the repayment of the revolving line of credit at our Italian subsidiary of $0.3 million, and offset by proceeds from the issuance of common stock related to the exercise of common stock options and our employee purchase plan of $0.3 million.

Contractual obligations. Our principal contractual obligations consist of operating leases, inventory purchase commitments, and income tax obligations for unrecognized tax benefits. The following table summarizes our commitments to settle contractual obligations as of December 31, 2009:


Contractual obligations	Total		Less than 1 year		1-3 years		3-5 years
	(in thousands)
Operating leases	$	1,685	$	990	$	672	$	23
Purchase commitments for inventory		17,738		4,405		9,161		4,172
Unrecognized tax benefits		299		299		—		—

Total contractual obligations	$	19,722	$	5,694	$	9,833	$	4,195

The commitments under our operating leases consist primarily of lease payments for our Burlington, Massachusetts, corporate headquarters and manufacturing facility and a separate manufacturing and storage facility in Burlington, Massachusetts, each expiring in 2011; our Sulzbach, Germany office, expiring in 2010; and our Tokyo, Japan office, expiring in 2010. On March 23, 2010, we extended our lease of our manufacturing facility in Burlington, Massachusetts through 2017. Additionally, we entered into a lease for an additional 16,629 square feet in an adjacent facility in Burlington, Massachusetts through 2017 while terminating the lease to our Burlington storage facility.

The purchase commitments for inventory are to be used in operations over the normal course of business and do not represent excess commitments or loss contracts.

Critical Accounting Policies and Estimates

We have adopted various accounting policies to prepare our consolidated financial statements in accordance with U.S. generally accepted accounting principles, or U.S. GAAP. Our most significant accounting policies are described in note 1 to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K. The preparation of our consolidated financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the amounts reported in our consolidated financial statements and accompanying notes. Our estimates and assumptions, including those related to bad debts, inventories, intangible assets, sales returns and discounts, and income taxes are reviewed on an ongoing basis and updated as appropriate. Actual results could differ from those estimates.

Certain of our more critical accounting policies require the application of significant judgment by management in selecting the appropriate assumptions for calculating financial estimates. By their nature, these judgments are subject to an inherent degree of uncertainty. These judgments are based on our historical experience, terms of existing contracts, observance of trends in the industry, and information provided by physicians who use our products and information available from other outside sources, as appropriate. Different, reasonable estimates could have been used in the current period. Additionally, changes in accounting estimates are reasonably likely to occur from period to period. Both of these factors could have a material impact on the presentation of our financial condition, changes in financial condition, or results of operations.

We believe that the following financial estimates and related accounting policies are both important to the portrayal of our financial condition and results of operations and require subjective or complex judgments. Further, we believe that the items discussed below are properly recorded in our consolidated financial statements for all periods presented. Management has discussed the development, selection and disclosure of our most critical financial estimates with the audit committee of our board of directors and our independent registered public accounting firm. The judgments about those financial estimates are based on information available as of the date of our consolidated financial statements. Those financial estimates and related policies include:

Revenue Recognition

Our revenue is derived primarily from the sale of disposable or implantable devices used during vascular surgery. We sell directly to hospitals and to distributors, as described below, and, during the periods presented in our consolidated financial statements, entered into consigned inventory arrangements with either hospitals or distributors on a limited basis.

We recognize revenue when four basic criteria are met: (1) Persuasive evidence of an arrangement exists; (2) delivery has occurred or services have been rendered; (3) the fee is fixed or determinable; and (4) collectability is reasonably assured. We generally use customer purchase orders or contracts to determine the existence of an arrangement. Substantially all sales transactions are based on prices that are determinable at the time that the customer’s purchase order is accepted by us. In order to determine whether collection is probable, we assess a number of factors, including past transaction history with the customer and the creditworthiness of the customer. If we determine that collection is not reasonably assured, we would defer the recognition of revenue until collection becomes reasonably assured, which is generally upon receipt of payment. We provide for product returns at the time revenue is recognized based on our historical return product history.

Accounts Receivable

determined by a review of their current credit information. We continuously monitor aging reports, collections, and payments from customers, and maintain a provision for estimated credit losses based upon historical experience and any specific customer collection issues we identify.

We write off accounts receivable when they become uncollectible. While such credit losses have historically been within our expectations and allowances, we cannot guarantee the same credit loss rates will be experienced in the future. The allowance for doubtful accounts is our best estimate of the amount of probable credit losses in our existing accounts receivable. We review our allowance for doubtful accounts on a monthly basis and all past due balances are reviewed individually for collectability. The provision for the allowance for doubtful accounts is recorded in general and administrative expenses.

Inventory

Inventory consists of finished products, work-in-process, and raw materials. We value inventory at the lower of cost or market value. Cost includes materials, labor, and manufacturing overhead and is determined using the first-in, first-out (FIFO) method. On a quarterly basis, we review inventory quantities on hand and analyze the provision for excess and obsolete inventory based primarily on product expiration dating and our estimated sales forecast, which is based on sales history and anticipated future demand. Our estimates of future product demand may not be accurate, and we may understate or overstate the provision required for excess and obsolete inventory. Accordingly, any significant unanticipated changes in demand could have a significant impact on the value of our inventory and results of operations.

Stock-based Compensation

We recognize, as expense, the estimated fair value of all share-based payments to employees which is determined using the Black-Scholes option pricing model. We have elected to recognize the compensation cost of all share-based awards on a straight-line basis over the vesting period of the award. In periods that we grant stock options, fair value assumptions are based on volatility, interest, dividend yield, and expected term over which the stock options will be outstanding. The computation of expected volatility is based on the historical volatility of the company’s stock. The interest rate for periods within the contractual life of the award is based on the U.S. Treasury risk-free interest rate in effect at the time of grant. The expected lives of the options were estimated using the simplified method for “plan vanilla” options. Computation of expected forfeitures is based on historical forfeiture rates of our stock options. We used an expected forfeiture rate of approximately 18%, 20%, and 20% for 2009, 2008 and 2007, respectively. Share-based compensation charges are recorded net of the estimated forfeitures and will be adjusted in future periods to reflect the results of actual forfeitures and vesting.

As disclosed more fully in the notes of our financial statements, we recorded expense of approximately $1.0 million in connection with share-based payment awards for the year ended December 31, 2009. The future expense of non-vested share-based awards of approximately $1.9 million is to be recognized over a weighted-average period of 3.5 years. During 2009, we granted stock options at a weighted average exercise price of $3.12 and restricted stock units with fair value weighted average price of $2.99.

Valuation of Goodwill, Other Intangibles

When we acquire a business, the purchase price is allocated, as applicable, among acquired tangible net assets, identifiable intangible assets, and goodwill as required by U.S. GAAP. Goodwill represents the excess of the aggregate purchase price over the fair value of net assets of the acquired businesses. Goodwill is tested for impairment annually or more frequently if changes in circumstance or the occurrence of events suggest impairment exists. We evaluate the December 31 balance of the carrying value of goodwill based on a single reporting unit. The first step of our goodwill impairment test, used to identify potential impairment, compares the fair value of our reporting unit with its carrying amount, including goodwill. If the fair value of our reporting unit exceeds its carrying amount, the goodwill of the reporting unit is considered not impaired, and thus the second

step of the impairment test, used to measure the amount of the impairment loss, is unnecessary. If the carrying amount of our reporting unit exceeds its fair value, the second step of the goodwill impairment test is performed to measure the amount of impairment loss, if any. The second step of the goodwill impairment test, used to measure the amount of impairment loss, compares the implied fair value of the reporting unit goodwill as of the date of the impairment review with the carrying amount of that goodwill. The implied fair value of our goodwill is determined on the same basis as the amount of goodwill recognized in connection with a business combination. Specifically, we allocate the fair value of our reporting unit to all of the assets and liabilities of that unit (including any unrecognized intangible assets) as if the reporting unit had been acquired in a business combination as of the date of the impairment review and as if the fair value of the reporting unit was the price paid to acquire the reporting unit. The excess of the fair value of a reporting unit over the amounts assigned to its assets and liabilities is the implied fair value of goodwill. If the carrying amount of the reporting unit goodwill exceeds the implied fair value of that goodwill, an impairment loss shall be recognized in an amount equal to that excess. We have determined that no impairment charges were required during the year ended December 31, 2009 as the market capitalization of the Company as a whole has exceeded the carrying amount, and on that basis we concluded that goodwill was not impaired. Goodwill was $11.0 million as of December 31, 2008 and 2009. Our annual impairment testing indicated no significant risk of impairment based upon changes in value that are reasonably likely to occur. However, changes in these estimates and assumptions could materially affect the estimated fair value of our reporting unit.

Other intangible assets consist primarily of purchased developed technology, patents, customer relationships, and trademarks and are amortized over their estimated useful lives, ranging from two to 17 years. We review intangible assets quarterly to determine if any adverse conditions exist for a change in circumstances has occurred that would indicate impairment. Conditions that may indicate impairment include, but are not limited to, a significant adverse change in legal factors or business climate that could affect the value of the asset, a change in the operating cash flows associated with the asset, or adverse action or assessment by a regulator. If an impairment indicator exists we test the intangible asset for recoverability. If the carrying value of the intangible asset exceeds the undiscounted cash flows expected to result from the use and eventual disposition of the intangible asset, we will write the carrying value down to the fair value in the period identified. We generally calculate fair value of our intangible assets as the present value of estimated future cash flows we expect to generate from the asset using a risk-adjusted discount rate. In determining our estimated future cash flows associated with our intangible assets, we use estimates and assumptions about future revenue contributions, cost structures, and remaining useful lives of the asset. These estimates and assumptions require significant judgment and actual results may differ from assumed or estimated amounts. Other intangible assets, net of accumulated amortization, were $2.9 million as of December 31, 2008, and $3.3 million as of December 31, 2009. We recognized impairment charges on our intangible assets of $0.6 million in 2008 and $0.1 million in 2009.

Contingencies

In the normal course of business, we are subject to proceedings, lawsuits, and other claims and assessments for matters related to, among other things, patent infringement, business acquisitions, employment, and product recalls. We assess the likelihood of any adverse judgments or outcomes to these matters as well as potential ranges of probable losses. A determination of the amount of reserves required, if any, for these contingencies is made after careful analysis of each individual issue. The required reserves may change in the future due to new developments in each matter or changes in approach such as a change in settlement strategy in dealing with these matters. We record charges for the costs we anticipate incurring in connection with litigation and claims against us when we determine a loss is probable and we can reasonably estimate these costs. During the years ended December 31, 2007, 2008, and 2009, we were not subject to any material litigation, claims or assessments.

Restructuring

We record restructuring charges incurred in connection with consolidation or relocation of operations, exited business lines, or shutdowns of specific sites. These restructuring charges, which reflect our commitment

to a termination or exit plan that will begin within twelve months, are based on estimates of the expected costs associated with site closure, legal matters, contract terminations, or other costs directly related to the restructuring. If the actual cost incurred exceeds the estimated cost, an additional charge to earnings will result. If the actual cost is less than the estimated cost, a credit to earnings will be recognized.

Income Taxes

As part of the process of preparing our consolidated financial statements we are required to determine our income taxes in each of the jurisdictions in which we operate. This process involves estimating our actual current tax expense together with assessing temporary differences resulting from recognition of items for income tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included within our consolidated balance sheet. We must then assess the likelihood that our deferred tax assets will be recovered from taxable income during the carryback period or in the future; and to the extent we believe that recovery is not likely, we must establish a valuation allowance. To the extent we establish a valuation allowance or increase this allowance in a period, we must reflect this increase as an expense within the tax provision in the statement of operations. We do not provide for income taxes on undistributed earnings of foreign subsidiaries, as our current intention is to permanently reinvest these earnings.

We recognize, measure, present and disclose in our financial statements, uncertain tax positions that we have taken or expects to take on a tax return. We operate in multiple taxing jurisdictions, both within the United States and outside of the United States and may be subject to audits from various tax authorities regarding transfer pricing, the deductibility of certain expenses, intercompany transactions, and other matters. Within specific countries, we may be subject to audit by various tax authorities operating within the country and may be subject to different statutes of limitation expiration dates. Management’s judgment is required in determining our provision for income taxes, our deferred tax assets and liabilities, liabilities for uncertain tax positions, and any valuation allowance recorded against our net deferred tax assets. We will continue to monitor the realizability of our deferred tax assets and adjust the valuation allowance accordingly. We have recorded a valuation allowance on our net deferred tax assets of $6.5 million in 2009 and $5.4 million in 2008.

Marketable Securities

Our investments consist primarily of marketable debt securities and U.S. government securities, and are classified as available-for-sale and are carried at fair market value at December 31, 2009. The unrealized gains (losses) on available-for-sale securities are recorded in accumulated other comprehensive income (loss). We consider all highly liquid investments with maturities of 90 days or less at the time of purchase to be cash equivalents, and investments with maturities of greater than 90 days at the time of purchase to be short-term investments. When a marketable security incurs a significant unrealized loss for a sustained period of time, we review the instrument to determine if it is other-than-temporarily impaired. If we conclude an instrument is other-than-temporarily impaired, we record the unrealized loss in the consolidated statement of operations.

Off-Balance Sheet Arrangements

We did not have any off-balance sheet arrangements as of December 31, 2009. We do not currently have, nor have we ever had, any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. In addition, we do not engage in trading activities involving non-exchange traded contracts. As a result, we are not materially exposed to any financing, liquidity, market, or credit risk that could arise if we had engaged in these relationships.

Recent Accounting Pronouncements

In December 2007 the Financial Accounting Standards Board (the FASB) revised the accounting rules concerning business combinations. This revised guidance requires the acquiring entity in a business combination to recognize the full fair value of assets acquired and liabilities assumed in the transaction; requires certain contingent assets and liabilities acquired to be recognized at their fair values on the acquisition date; requires contingent consideration to be recognized at its fair value on the acquisition date and changes in the fair value to be recognized in earnings until settled; requires the expensing of most transaction and restructuring costs; and generally requires the reversals of valuation allowances related to acquired deferred tax assets and changes to acquired income tax uncertainties to also be recognized in earnings. The revised guidance was effective for business combination transactions consummated after December 31, 2008. There was no impact upon adoption; however, the rule changes may materially affect the accounting for any future business combinations.

In December 2007, the FASB issued new rules on noncontrolling interests in consolidated financial statements. The noncontrolling interest guidance changed the accounting for minority interests, which are reclassified as noncontrolling interests and classified as a component of equity. We adopted this guidance effective January 1, 2009. The adoption did not have an effect on our consolidated results of operations or financial condition.

In February 2008, the FASB delayed the effective date of the fair value accounting standard for all nonfinancial assets and nonfinancial liabilities, except for those that are recognized or disclosed at fair value in the financial statements on a recurring basis. The Company adopted the provisions of the standard for nonfinancial assets and nonfinancial liabilities as of January 1, 2009. The adoption did not have an effect on our consolidated results of operations or financial condition.

In March 2008, the FASB issued a pronouncement pertaining to disclosures about derivative instruments and hedging activities. This guidance requires disclosures of how and why an entity uses derivative instruments; how derivative instruments and related hedged items are accounted for; and how derivative instruments and related hedged items affect an entity’s financial position, financial performance and cash flows. We adopted this guidance effective January 1, 2009. The adoption did not have an effect on our consolidated results of operations or financial condition.

In April 2008 the FASB provided guidance for determining the useful life of recognized intangible assets and to improve consistency between the period of expected cash flows used to measure the fair value of a recognized intangible asset and the useful life of the intangible asset. We adopted this guidance effective January 1, 2009 and will apply its provisions prospectively to recognized intangible assets acquired after that date. The adoption did not have an effect on our consolidated results of operations or financial condition.

In April 2009, the FASB issued guidance on the recognition and presentation of other-than-temporary impairments. This guidance amends the prior other-than-temporary impairment guidance for certain debt securities and will require the investor to assess the likelihood of selling the debt security prior to recovery of its cost basis. If an investor is able to meet the criteria to assert that it does not intend to sell the debt security and more likely than not will not be required to sell the debt security before its anticipated recovery, impairment charges related to credit losses would be recognized in earnings whereas impairment charges related to non-credit losses would be reflected in other comprehensive income. We elected early adoption of this rule in the first quarter of 2009. The adoption of the new other-than-temporary guidance had no impact on our consolidated results of operations or financial condition.

disclosures that an entity shall make about events or transactions that occurred after the balance sheet date. We adopted the pronouncement for the our second quarter 2009, and there was no effect from adoption.

In June 2009, the FASB issued guidance on the FASB Accounting Standards Codification and hierarchy of generally accepted accounting principles. The FASB Accounting Standards Codification (the Codification), is the single source of authoritative nongovernmental generally accepted accounting principles in the U. S. GAAP. The Codification is effective for interim and annual periods ending after September 15, 2009. The adoption of the Codification had no impact on our consolidated results of operations or financial condition.

In September 2009, the Emerging Issues Task Force issued the new rules pertaining to the accounting for revenue arrangements with multiple deliverables. The new rules provide an alternative method for establishing fair value of a deliverable when vendor specific objective evidence cannot be determined. The guidance provides for the determination of the best estimate of selling price to separate deliverables and allows the allocation of arrangement consideration using this relative selling price model. The guidance supersedes the prior multiple element revenue arrangement accounting rules that we previously used. The new guidance is effective for fiscal years beginning on or after June 15, 2010 and can be early or retrospectively adopted. We have elected to adopt the new revenue recognition guidance retrospectively as of January 1, 2009. The adoption of the new revenue recognition guidance had no impact on our consolidated results of operations or financial condition as we generally do not enter into multiple element revenue arrangements.

Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Based on their evaluation as of December 31, 2009, our Chief Executive Officer and Chief Financial Officer, with the participation of management, have concluded that our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934) were effective at reasonable assurance levels.

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) to provide reasonable assurance regarding the reliability of our financial reporting and the preparation of financial statements for external purposes in accordance with U.S. generally accepted accounting principles.

Management assessed the effectiveness of our internal controls over financial reporting as of December 31, 2009. Management based its assessment on criteria established in the Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Management’s assessment included evaluation of elements such as the design and operating effectiveness of key financial reporting controls, process documentation, accounting policies, and our overall control environment.

Based on this assessment under the criteria set forth in the Internal Control—Integrated Framework, management has concluded that our internal control over financial reporting was effective as of December 31, 2009.

This Annual Report on Form 10-K does not include an attestation report of our registered public accounting firm regarding internal control over financial reporting. Management's report was not subject to attestation by our registered public accounting firm pursuant to temporary rules of the Securities and Exchange Commission that permit us to provide only management's report in this Annual Report on Form 10-K.

Pursuant to Item 308T of Regulation S-K, this management’s report on internal control over financing reporting shall not be deemed filed for purposes of Section 18 of the Exchange Act or otherwise subject to the liabilities of that section.

Changes in Internal Control over Financial Reporting

There was no change in the our internal control over financial reporting that occurred during the fiscal quarter ended December 31, 2009, that has materially affected, or is reasonably likely to materially affect our internal control over financial reporting.

Inherent Limitations of Internal Controls

Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures or our internal controls will prevent all error and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, control may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

Item 9B.

Other Information

On March 23, 2009, we entered into a series of agreements with Roger P. Nordblom and Peter C. Nordblom, as Trustees of Northwest Associates (Northwest Associates) amending and extending the lease for our principal executive, distribution and manufacturing operations in Burlington, Massachusetts and entering into a substantially co-terminus lease agreement for space in a building on a neighboring parcel. We intend to connect these buildings via a covered walkway and treat both buildings as a single operating facility that will continue to serve as our worldwide headquarters.

More specifically, we entered into a Fifth Amendment to Lease with Northwest Associates (the Amendment) for our worldwide headquarters at 63 Second Avenue, Burlington, Massachusetts, pursuant to which we lease a 27,098 square foot facility. The Amendment extends the term of this lease from 2011 until approximately 2017, with the precise date to be determined by reference to the commencement date of our lease of space in the facility located at 53 Second Avenue, Burlington, Massachusetts. The Amendment reduces the monthly base rental payment from approximately $25,000 to approximately $20,000. In addition to base rent, we will pay the annual real estate taxes and most operating expenses of the building. The Amendment also makes certain other amendments to the terms of the original lease to be consistent with the terms of the new 53 Second Avenue lease.

We also entered into a new Lease (the Lease) with Northwest Associates, initially for 16,629 square foot facility at 53 Second Avenue, Burlington, Massachusetts, for a term of seven years, expected to commence in 2010 upon the completion of a build-out of the new facility. The Lease requires Northwest Associates to contribute up to $100,000 to the build-out. Pursuant to the Lease, during the first 30 months of the Lease following the commencement date, the monthly base rental payment will be approximately $11,000. Thereafter, for the remaining term of the Lease, the facility is expanded by 10,660 square feet, creating a total 27,289 square foot facility, and the monthly base rental payment increases to approximately $18,000. In addition to base rent, we will pay the annual real estate taxes and most operating expenses of the building. Following the commencement of the Lease, our separate lease for a nearby 7,477 square foot facility that we lease from an affiliate of Northwest Associates will become terminable upon 30 days notice by either us or the landlord.

The foregoing statement does not purport to be a complete statement of the parties’ rights and obligations under either the Amendment or the Lease, or the transactions contemplated by either. The foregoing description is qualified in its entirety by reference to the Amendment, a copy of which is filed herewith as Exhibit 10.33, to previously filed documents pertaining to our 63 Second Avenue facility, which are Exhibits 10.1, 10.24., 10.27, and 10.28 to this Annual Report on Form 10-K, and the Lease, a copy of which is filed herewith as Exhibit 10.34, all of which are incorporated herein by reference.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders of LeMaitre Vascular, Inc.

We have audited the accompanying consolidated balance sheets of LeMaitre Vascular, Inc. as of December 31, 2009 and 2008, and the related consolidated statements of operations, stockholders' equity and comprehensive income (loss), and cash flows for each of the three years in the period ended December 31, 2009. Our audit also included the financial statement schedule listed at Item 15(a)2. These financial statements and schedule are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements and schedule based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. We were not engaged to perform an audit of the Company's internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of LeMaitre Vascular, Inc. at December 31, 2009 and 2008, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2009, in conformity with U.S. generally accepted accounting principles. Also, in our opinion, the related financial statement schedule, when considered in relation to the basic financial statements taken as a whole, presents fairly in all material respects the information set forth therein.

LeMaitre Vascular, Inc.

Notes to Consolidated Financial Statements

December 31, 2009

1. Significant Accounting Policies and Related Matters

Description of Business

Unless the context requires otherwise, references to LeMaitre Vascular, we, our, and us refer to LeMaitre Vascular, Inc. LeMaitre Vascular develops, manufactures, and markets medical devices and implants used primarily in the field of vascular surgery. We operate in a single segment in which our principal product lines are thoracic stent grafts, abdominal stent grafts, anastomotic clips, radiopaque tape, valvulotomes, carotid shunts, arterial prostheses, remote endarterectomy devices, covered stents, contrast injectors, balloon catheters, vascular grafts, vein strippers, cholangiogram catheters and vascular access ports. We also distribute in 12 European countries an abdominal stent graft manufactured by a third party. In addition, we distribute in the United States and European Union a biological vascular patch manufactured by a third party. Our offices are located in Burlington, Massachusetts, Sulzbach, Germany, Rome, Italy, Brindisi, Italy, and Tokyo, Japan.

Consolidation and Basis of Presentation

Our consolidated financial statements include the accounts of LeMaitre Vascular and the accounts of our wholly-owned subsidiaries, LeMaitre Vascular GmbH, LeMaitre Vascular GK (successor to LeMaitre Vascular KK, reorganized in June 2007), LeMaitre UK Acquisition LLC, Vascutech Acquisition LLC, LeMaitre Acquisition LLC, LeMaitre Vascular SAS (organized in 2007), Biomateriali S.r.l. (acquired in 2007), and LeMaitre Vascular S.r.l. (organized in 2007). All significant intercompany accounts and transactions have been eliminated in consolidation.

Certain prior year amounts have been reclassified in the consolidated financial statements and accompanying notes to conform to the current year presentation.

Foreign Currency Translation

Balance sheet accounts of foreign subsidiaries are translated into U.S. dollars at year-end exchange rates. Operating accounts are translated at average exchange rates for each year. Net translation gains or losses are adjusted directly to a separate component of other comprehensive income (loss) within stockholders’ equity.

Foreign exchange transaction gains (losses), substantially all of which relate to intercompany activity between us and our foreign subsidiaries, amounted to $0.3 million in 2009, ($0.1) million in 2008, and $0.3 million in 2007 and are included in other income (expense) in the accompanying consolidated statements of operations.

Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles (GAAP) requires us to make estimates and assumptions that affect the amounts reported in our consolidated financial statements and accompanying notes. Our estimates and assumptions, including those related to bad debts, inventories, intangible assets, sales returns and discounts, and income taxes are reviewed on an ongoing basis and updated as appropriate. Actual results could differ from those estimates.

Revenue Recognition

F-9

After the delivery of the product, there is no uncertainty about customer acceptance due to the nature of the product. There is no contingency for acceptance, warranty, or price protection. We do not recognize revenue on consigned sales until the customer notifies us that the products have been used. In order to determine whether collection is probable, we assess a number of factors, including past transaction history with the customer and the creditworthiness of the customer. If we determine that collection is not reasonably assured, we defer the recognition of revenue until collection becomes reasonably assured, which is generally upon receipt of payment. We provide for product returns at the time revenue is recognized based on our historical product return history.

Based on these policies, we recognize revenue, net of allowances for returns and discounts, as products are shipped, based on shipping point terms, at which time title passes to customers. Customers returning products are entitled to full or partial credit based on the condition and timing of the return. To be accepted, a returned product must be unopened (if sterile), unadulterated, and undamaged, and must have at least 18 months remaining prior to its expiration date, or 12 months for our hospital customers in Europe. These return policies apply to sales to both hospitals and distributors. Our products are subject to a limited warranty that our products have been manufactured with due care. The amount of products returned to us, either for exchange or credit, has not been material. Nevertheless, we provide for an allowance for future sales returns based on historical return experience. Our cost of replacing defective products has not been material and is accounted for at the time of replacement.

Research and Development Expense

Research and development costs, principally salaries and supplies, are expensed as incurred.

Shipping and Handling Costs

Shipping and handling fees paid by customers are recorded as sales, with the related expense recorded in cost of sales.

Advertising Costs

Advertising costs are expensed as incurred and are included as a component of sales and marketing expense in the accompanying Consolidated Statements of Operations. Advertising costs amounted to $0.4 million in 2009, $0.6 million in 2008, and $0.6 million in 2007.

Cash and Cash Equivalents

We consider all highly liquid instruments purchased with maturity dates of 90 days or less to be cash equivalents. Cash and cash equivalents are primarily invested in fully collateralized overnight repurchase agreements. These amounts are stated at cost, which approximates fair value.

Marketable Securities

Our investments consist primarily of marketable debt securities and U.S. government securities, which are classified as available-for-sale and are carried at fair market value at December 31, 2009 and December 31, 2008. The unrealized gains (losses) on available-for-sale securities are recorded in accumulated other comprehensive income (loss). We consider all highly liquid investments with maturities of 90 days or less at the time of purchase

F-10

to be cash equivalents, and investments with maturities of greater than 90 days at the time of purchase to be marketable securities. When a marketable security incurs a significant unrealized loss for a sustained period of time, we review the instrument to determine if it is other-than-temporarily impaired. If we conclude an instrument is other-than-temporarily impaired, we record the unrealized loss in the consolidated statement of operations.

Concentrations of Credit Risk

Our financial instruments that are exposed to concentrations of credit risk consist primarily of cash and cash equivalents, marketable securities, and accounts receivable. Cash equivalents represent highly liquid investments with maturities of 90 days or less at the date of purchase. Marketable securities are investment grade, interest-earning securities and are diversified by type and industry. Credit risk related to cash, cash equivalents, and marketable securities are limited based on the creditworthiness of the financial institutions at which these funds are held.

Our accounts receivable are with customers based in the United States and internationally. Accounts receivable generally are due within 30 to 90 days of invoice and are stated at amounts due from customers, net of an allowance for doubtful accounts and sales returns, other than in certain European markets where longer payment terms are customary. We perform ongoing credit evaluations of the financial condition of our customers and adjust credit limits based upon payment history and the current creditworthiness of the customers, as determined by a review of their current credit information. We continuously monitor aging reports, collections, and payments from customers, and maintain a provision for estimated credit losses based upon historical experience and any specific customer collection issues we identify.

Fair Value of Financial Instruments

Our financial instruments include cash and cash equivalents, marketable securities, accounts receivable, trade payables, and notes payable. The fair value of the majority of these instruments approximates their carrying value based upon their short-term nature or variable rates of interest. The deferred payments associated with the Biomateriali S.r.l. acquisition were recorded at the present value using our incremental borrowing rate in the consolidated balance sheet for the year ended December 31, 2008. The difference between the present value and the amount due was amortized using the effective interest method over the period that each of liabilities is outstanding. The amortization was recorded as interest expense.

Inventory

F-11

Property and Equipment

Property and equipment are recorded at cost. Depreciation is provided over the estimated useful lives of the related assets using straight-line method as follows:


Description		Useful Life
Computers and equipment		3–5 years
Machinery and equipment		3–10 years
Leasehold improvements		The shorter of its useful life or lease term

Expenditures for maintenance and repairs are charged to operations when incurred, while additions and betterments are capitalized. When assets are retired or disposed, the asset’s original cost and related accumulated depreciation are eliminated from the accounts and any gain or loss is reflected in the statement of operations.

Valuation of Business Combinations

We record intangible assets acquired in business combinations under the purchase method of accounting by allocating the amounts paid for each acquisition to the assets acquired and liabilities assumed based on their fair values at the dates of the acquisition. The purchase price in excess of net tangible assets acquired is allocated to the identifiable intangible assets based on their fair value. The fair value of identifiable intangible assets is usually based upon detailed valuations performed by independent appraisers that use information and assumptions provided by management. We allocate any excess purchase price over the fair value of the net tangible and intangible assets acquired to goodwill.

Contingent Consideration

Certain of our business combinations from 2007 and 2008 involve the payment of contingent consideration. We establish a contingent consideration liability at the acquisition date when the initial purchase price before including any contingent consideration is less than the sum of the fair value assigned to the assets acquired and the liabilities assumed (the excess). The liability established equals the lesser of the maximum amount of the potential contingent consideration or the excess. When the contingencies are resolved, any excess of the fair value of the contingent payments over the amount that was recognized as if it were a liability shall be recognized as an additional cost of the related acquisition (see Note 3). If the amount initially recognized as if it were a liability exceeds the fair value of the contingent payments made, the excess shall be allocated as a pro rata reduction of the amounts initially assigned to the identifiable intangible assets acquired.

For business combinations completed after January 1, 2009, the FASB requires contingent consideration be recognized at the date of acquisition, based on the fair value at that date, and then re-measured periodically through adjustments to net income.

Impairment of Long-lived Assets

We review the carrying value of our long-lived assets (primarily property and equipment and intangible assets) to assess the recoverability of these assets when indicators of impairment occur. We record impairment losses on long-lived assets used in operations when events and circumstances indicate that the assets might be impaired and the undiscounted cash flows estimated to be generated by those assets are less than the carrying amount of those assets. Impairment is measured based on the fair market value of the affected asset using discounted cash flows.

In January 2008 we were notified by one of the customers of our Biomateriali subsidiary that they would no longer purchase a certain product line from us, and, as a result, we recorded an impairment charge of $0.4 million due to the write-down of related intangible assets. As of December 31, 2008, we determined that an impairment

F-12

indicator existed with respect to the remaining product line with this Biomateriali customer. Consequently, we recorded an impairment charge of $84,000 to reduce the carrying value of these assets to their estimated fair value of $0.1 million. Fair value was determined by projected future cash flows discounted to their net present value.

In 2008, we also recognized impairment charges of $78,000 related to patents and trademarks which were deemed to have no value based upon a lack of future expected economic benefits. In March 2009 we determined that certain patents within our endovascular product category portfolio in the United States and Europe had no value based upon an analysis of expected economic benefits. As a result, we recorded an impairment charge of $0.1 million for the write-down of these patents. In 2009, we also recognized impairment charges of $30,000 related to patents and trademarks which were deemed to have no value based upon a lack of future expected economic benefits.

Goodwill

Goodwill represents the amount of consideration paid in connection with business acquisitions in excess of the fair value of assets acquired and liabilities assumed. Goodwill is evaluated for impairment annually or more frequently if indicators of impairment are present or changes in circumstances suggest that impairment may exist. We evaluate the December 31 balance of the carrying value of goodwill based on a single reporting unit annually. The first step of our goodwill impairment test, used to identify potential impairment, compares the fair value of our reporting unit with its carrying amount, including goodwill. If the fair value of our reporting unit exceeds its carrying amount, the goodwill of the reporting unit is considered not impaired, and the second step of the impairment test, used to measure the amount of the impairment loss, is unnecessary. If the carrying amount of our reporting unit exceeds its fair value, the second step of the goodwill impairment test is performed to measure the amount of impairment loss, if any. The second step of the goodwill impairment test, used to measure the amount of impairment loss, compares the implied fair value of the reporting unit goodwill as of the date of the impairment review with the carrying amount of that goodwill. The implied fair value of goodwill is determined on the same basis as the amount of goodwill recognized in connection with a business combination. Specifically, the fair value of a reporting unit is allocated to all of the assets and liabilities (including any unrecognized intangible assets) as if the reporting unit had been acquired in a business combination as of the date of the impairment review and as if the fair value of the reporting unit was the price paid to acquire the reporting unit. The excess of the fair value of a reporting unit over the amounts assigned to its assets and liabilities is the implied fair value of goodwill. If the carrying amount of the reporting unit goodwill exceeds the implied fair value of that goodwill, an impairment loss shall be recognized in an amount equal to that excess. We have determined that no goodwill impairment charges were required for the years ended December 31, 2009, 2008, or 2007.

Other Intangible Assets

Other intangible assets consist primarily of patents, trademarks, technology licenses, and customer relationships acquired in connection with business acquisitions and are amortized over their estimated useful lives, ranging from 2 to 17 years.

Stock-based Compensation

F-13

estimated using the simplified method for “plan vanilla” options. Computation of expected forfeitures is based on historical forfeiture rates of our stock options. We used an expected forfeiture rate of approximately 18%, 20%, and 20% for 2009, 2008 and 2007, respectively. Share-based compensation charges are recorded net of the estimated forfeitures and will be adjusted in future periods to reflect the results of actual forfeitures and vesting.

The components of share-based compensation expense included in net loss are as follows:


	2009		2008			2007
	(in thousands)
Stock option awards to employees	$	300	$	310		$	241
Restricted common stock awards		685		499			303
Employee stock purchase plan		—		—			8
Stock option awards to non-employees		—		(8	)		9

Total stock-based compensation	$	985	$	801		$	561

We expect to record the unamortized portion of share-based compensation expense of $1.9 million for existing stock options and restricted stock units (RSUs) outstanding at December 31, 2009, over a weighted-average period of 3.5 years.

Commitments and Contingencies

In the normal course of business, we are subject to proceedings, lawsuits, and other claims and assessments for matters related to, among other things, patent infringement, business acquisitions, employment, and product recalls. We assess the likelihood of any adverse judgments or outcomes to these matters as well as potential ranges of probable losses. A determination of the amount of reserves required, if any, for these contingencies is made after careful analysis of each individual issue. The required reserves may change in the future due to new developments in each matter or changes in approach such as a change in settlement strategy in dealing with these matters. We record charges for the costs we anticipate incurring in connection with litigation and claims against us when we conclude a loss is probable and we can reasonably estimate these costs. During the years ended December 31, 2009, 2008, and 2007, we were not subject to any material litigation or claims and assessments.

Income Taxes

We account for income taxes under the asset and liability method of accounting for income taxes. Under the asset and liability method, deferred taxes are determined based on the difference between the financial reporting and tax bases of assets and liabilities using enacted tax rates in effect in the years in which the differences are expected to reverse. The provision for income taxes includes taxes currently payable and deferred taxes resulting from the tax effects of temporary differences between the financial statement and tax bases of assets and liabilities. We maintain valuation allowances where it is more likely than not that all or a portion of a deferred tax asset will not be realized. Changes in the valuation allowances are included in our tax provision in the period of change. In determining whether a valuation allowance is warranted, we evaluate factors such as prior earnings history, expected future earnings, carry-back and carry-forward periods and tax strategies that could potentially enhance the likelihood of the realization of a deferred tax asset.

We recognize, measure, present and disclose in our financial statements, uncertain tax positions that we have taken or expect to take on a tax return. We recognize in our financial statements the impact of tax positions that meet a “more likely than not” threshold, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position should be measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement.

Our policy is to classify interest and penalties related to unrecognized tax benefits as income tax expense, which is consistent with that of prior years.

F-14

Comprehensive Income (Loss)

Comprehensive income (loss) is defined as the change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources. Other than reported net income (loss), comprehensive income (loss) includes foreign currency translation adjustments and unrealized gains and losses on available-for-sale marketable securities, which are disclosed in the accompanying consolidated statements of stockholders’ equity and comprehensive income (loss).

As of December 31, 2009, accumulated other comprehensive loss consisted of unrealized gains on available-for-sale securities of $4,000 and foreign currency translation adjustment gains of $90,000. As of December 31, 2008, accumulated other comprehensive loss consisted of unrealized losses on available-for-sale securities of $91,000 and foreign currency translation adjustment losses of $181,000.

Restructuring

We record restructuring charges incurred in connection with consolidation or relocation of operations, exited business lines, shutdowns of specific sites, or distributor terminations. These restructuring charges, which reflect our commitment to a termination or exit plan that will begin within 12 months, are based on estimates of the expected costs associated with site closure, legal matters, contract terminations, employee separation arrangements, or other costs directly related to the restructuring. If the actual cost incurred exceeds the estimated cost, an additional charge to earnings will result. If the actual cost is less than the estimated cost, a credit to earnings will be recognized.

Net Income (Loss) Per Share

We compute basic earnings per share by dividing net income available for common stockholders by the weighted average number of shares outstanding during the year. Except where the result would be anti-dilutive to income from continuing operations, diluted earnings per share has been computed using the treasury stock method for the vesting of restricted common stock and the exercise of stock options, as well as their related income tax effects.

The computation of basic and diluted net income (loss) per share is as follows:


	Year ended December 31,
	2009		2008			2007
	(in thousands, except per share data)
Basic:
Net income (loss) available for common stockholders	$	1,598	$	(3,314	)	$	(2,934	)

Weighted average shares outstanding		15,687		15,572			15,398

Basic net income (loss) per share	$	0.10	$	(0.21	)	$	(0.19	)

Diluted:
Net income (loss) available for common stockholders	$	1,598	$	(3,314	)	$	(2,934	)

Weighted-average shares outstanding		15,687		15,572			15,398
Common stock equivalents, if dilutive		229		—			—

Shares used in computing diluted net income (loss) per common share		15,916		15,572			15,398

Diluted net income (loss) per share	$	0.10	$	(0.21	)	$	(0.19	)

F-15

For 2009 shares used in computing diluted net income per common share excludes 303,958 weighted-average shares of common stock issuable upon exercise of outstanding stock options and vesting of RSUs, as the effect of including those shares would be anti-dilutive.

For 2008 shares used in computing diluted net loss per common share excludes 394,257 weighted-average shares of common stock issuable upon exercise of outstanding stock options and vesting of RSUs, as the effect of including those shares would be anti-dilutive. An additional 232,845 of common stock equivalents were excluded as a result of our net loss for the period.

For 2007 shares used in computing diluted net loss per common share excludes 737,053 weighted-average shares of common stock issuable upon exercise of outstanding stock options and vesting of RSUs, as the effect of including those shares would be anti-dilutive. An additional 451,864 of common stock equivalents were excluded as a result of our net loss for the period.

Recent Accounting Pronouncements

F-16

In May 2009, the FASB issued a pronouncement on subsequent event accounting that establishes the period after the balance sheet date during which management shall evaluate events or transactions that may occur for potential recognition or disclosure in the financial statements; the circumstances under which an entity shall recognize events or transactions occurring after the balance sheet date in its financial statements; and the disclosures that an entity shall make about events or transactions that occurred after the balance sheet date. We adopted the pronouncement for our second quarter 2009, and there was no effect from adoption.

2. Marketable Securities

Marketable securities are primarily available-for-sale investments and consist of the following:


	As of December 31, 2009								As of December 31, 2008
	Amortized Cost		Gross Unrealized Gains		Gross Unrealized Losses		Fair Value		Amortized Cost		Gross Unrealized Gains		Gross Unrealized Losses			Fair Value

Total marketable securities	$	804	$	4	$	—	$	808	$	5,450	$	1	$	(92	)	$	5,359

Gross realized gains and losses on the sales of available-for-sale marketable securities were not material and have been included in interest income in the consolidated statements of operations for 2009, 2008, and 2007.

F-17

In 2008, we recorded an investment impairment charge of $0.2 million which was attributed to the other-than-temporary decline in one asset backed security which we held as available-for-sale in our marketable securities portfolio at December 31, 2008.

The amortized cost and estimated fair value of available-for-sale marketable securities as of December 31, 2009, by contractual maturity, were as follows:


	2009
	Amortized Cost		Fair Value
	(in thousands)
Contractual maturities:
Due in 1 year or less	$	557	$	557
Due in 1–2 years		247		251

Total	$	804	$	808

3. Acquisitions

Biomateriali

In December 2007 we acquired all of the stock of Biomateriali, S.r.l. (Biomateriali) a privately held Italian company. Biomateriali manufactures polyester grafts for use in open abdominal aortic aneurysm and peripheral vascular procedures, which we branded the AlboGraft Vascular Graft. Our consolidated financial statements include the operating results for Biomateriali from the date of the acquisition.

The aggregate purchase price was $3.4 million in cash and included: a $1.9 million cash payment on the date of the acquisition; $1.1 million deferred payment for the assumption of outstanding debt to their shareholders and their officers, of which $0.5 million was paid in 2008 and $0.6 million was paid in 2009; $0.2 million of direct acquisition costs; and $0.2 million for a deferred purchase price payment which was paid in 2009. The deferred payments have been included in Acquisition-related obligations in the December 31, 2008 balance sheet.

The following table summarizes the final purchase accounting for the fair value of the assets acquired and liabilities assumed at the date of the acquisition:


	Allocated Fair Value
	(in thousands)
Current assets	$	2,205
Property, plant, and equipment		456
Intangible assets		1,238
Other assets		1,186
Goodwill		100

Total assets acquired		5,185
Current liabilities		(1,417	)
Other liabilities		(388	)

Total liabilities assumed		(1,805	)

	$	3,380

F-18

Of the $1.2 million of acquired intangible assets, the following table reflects the allocation of the acquired intangible assets and related estimated useful lives:


	Allocated Fair Value		Weighted Average Useful Life
	(in thousands)
Customer and contract relationships	$	622	7.5 years
Patents		283	9.5 years
Trade names		283	9.5 years
Non-compete agreement		50	4.0 years

Total intangible assets	$	1,238

Based on developments since the date of acquisition, we recorded impairment charges of $0.5 million on the Biomateriali intangible assets in 2008 as discussed in Note 1.

AlboGraft Distribution Agreement

In March 2009, we entered into a series of agreements with Edwards Lifesciences AG (“Edwards”) to terminate their distribution of our AlboGraft Vascular Graft product line in Europe and certain other international markets, for which they had exclusive rights through 2011, and to acquire certain assets and rights from Edwards. We paid $3.5 million to Edwards in exchange for this early termination, the purchase of their AlboGraft customer list, certain licenses and most of their remaining AlboGraft inventory. We allocated the payment to the tangible and intangible assets acquired, and to the settlement of our pre-existing relationship with Edwards, based on the estimated fair value of each of these elements to the transaction. As such, we recorded $1.0 million of intangible assets, recognized a $1.8 million restructuring charge related to the early termination of the distribution agreement, and $0.7 million of inventory.

Vascular Architects

In September 2007 we acquired substantially all of the assets of Vascular Architects (VA), a privately held medical device company. VA marketed and sold devices for remote endarterectomy, a hybrid open/endovascular medical procedure. The aggregate purchase price was $2.9 million in cash and assumed liabilities. Under the terms of the purchase agreement, we acquired certain customer contracts, patents, and other intellectual property, in exchange for the assumption of certain liabilities. Approximately $2.5 million was paid upon the execution of the purchase agreement and $0.3 million was paid on the first anniversary of the signing in September 2008.

The following table summarizes final purchase accounting for the fair value of the assets acquired and liabilities assumed at the date of the acquisition:


	Allocated Fair Value
	(in thousands)
Current assets	$	543
Property, plant, and equipment		3
Intangible assets		658
Goodwill		1,758

Total assets acquired		2,962

Customer relationships	$	375	7.5 years
Patents		141	8.0 years
Trade names		34	8.0 years
Non-complete agreement		108	5.0 years

Total intangible assets	$	658

Acquisitions of Technology

In December 2007 we purchased certain patents and in-process research and development, and entered into a non-compete agreement with Arizona Heart Innovative Technologies, LLC. Total consideration paid included $0.5 million in cash at the acquisition date and certain earn-out payments associated with the receipts of approvals to commercialize the device in the European Union and the United States. Additionally, we are obligated to pay a milestone payment of $100,000 upon the issuance of any U.S. patent that matures from any of the applications acquired in the transaction. The fair value of the acquired in-process research and development of $373,000 was expensed on the date of acquisition, as it had not yet reached technological feasibility and had no alternative future use at the date of acquisition. The fair value of this acquired in-process research and development is reported as purchased research and development in our 2007 consolidated statement of operations. The purchase price was allocated to the identifiable intangible assets based on their fair values at the date of the acquisition as determined by a valuation from an independent appraiser. We considered the $100,000 milestone payment and earn-out payments associated with the receipts of approvals to commercialize the products in Europe and the United States to be contingent consideration that will be recorded as additional intangible assets in the period that the contingency is resolved.

In November 2007 we also acquired patents and patent applications in process for a total purchase price of $62,500, and these have been capitalized as patents. We are contractually obligated to make royalty payments on any sales from the technology purchased. In 2009, we determined that we had failed to meet two product development milestones relating to this agreement, and subsequently determined that the patents had no value based upon an analysis of expected economic benefits. As a result, we recorded $0.1 million charge associated with the missed milestones, which we paid in December 2009, and we recorded an impairment charge of $0.1 million for the write-down of these patents. In November 2009, we amended the agreement to license additional intellectual property in consideration for a revised royalty payment on any future products brought to market under the protection of the licensed intellectual property.

7. Financing Arrangements

We maintain a $10.0 million revolving line of credit that provides for up to $3.0 million in letters of credit. Loans made under this revolving line of credit bear interest at the bank’s base rate or LIBOR plus 200 basis points, at our discretion, and are collateralized by substantially all of our assets. The loan agreement requires that we meet certain financial and operating covenants including a required leverage ratio and minimum tangible net worth. On August 23, 2009, we extended the revolving line of credit to August 23, 2011. The extended agreement requires us to pay an annual commitment fee equal to 0.30% of the commitment amount, which is currently $10.0 million. As of December 31, 2009 and December 31, 2008, we did not have an outstanding balance under this facility and we were in compliance with these covenants.

Our Biomateriali subsidiary had two existing revolving lines of credit with their bank for a total of approximately $0.7 million to be used in connection with the financing of sales to certain customers at the date we acquired it. Loans made under these lines bear interest at 20% per annum. Both lines were paid in full and closed in January 2008.

Also, as part of the purchase of Biomateriali, we assumed a loan from the Italian government under a program that provides funding to certain businesses in Italy through a combination of grants and loans if certain requirements are met. In September 2009, the Italian government issued the second and final portion of the loan for approximately $0.1 million. The loan is payable in ten annual payments of principal and interest at an interest rate of 0.74%. The present value of the loan was recorded as of the date the proceeds were received using our incremental borrowing rate. Interest is being imputed on the loan, and the difference between the present value and the amount due will be amortized using the effective interest method over the period that the loan is outstanding. The amortization will be recorded as interest expense. The amount of the loan outstanding was approximately $0.2 million and $0.1 million as of December 31, 2009 and December 31, 2008, respectively, and has been included in our balance sheet in long-term debt. The loan is due in installments through 2018.

9. Commitments and Contingencies

Leases

We conduct certain of our operations in leased facilities, which are accounted for as operating leases. Certain leases include renewal options. Rent expense was $1.3 million in 2009, $1.5 million in 2008, and $1.2 million in 2007. In addition, we lease automobiles and equipment under operating leases. There were no assets held under capital leases at December 31, 2009, 2008 and 2007.

At December 31, 2009, the minimum rental commitments under all non-cancelable operating leases with initial or remaining terms of more than one year, for each of the following fiscal years, are as follows:


	Operating Leases

2011		555
2012		117
2013		14
2014		9

Total	$	1,685

On March 23, 2010, we extended our lease of our manufacturing facility in Burlington, Massachusetts through 2017. Additionally, we entered into a lease for an additional 16,629 square feet in an adjacent facility in Burlington, Massachusetts through 2017 while terminating the lease to our Burlington storage facility. The operating lease commitments resulting from these amendments are not included in the table above.

Purchase Commitments

As part of our normal course of business, we have purchase commitments to purchase $18.4 million of inventory through 2015. The purchase commitments for inventory are to be used in operations over the normal course of business and do not represent excess commitments or loss contracts.

Other Commitments

As discussed in Note 3, we purchased certain patent applications and in-process research and development which included earn-out payments associated with the commercialization of the device in the European Union and the United States as part of the consideration. The earn-out payments are payable quarterly at approximately the rate of two times sales for the four quarters. The European earn-out period is measured from December 23, 2009 through December 22, 2010. We recorded an intangible asset and a liability of approximately $5,000 related to the 2009 sales volume. The United States earn-out period is measured for four quarters following the first commercial sale in the United States. We consider the earn-out payments associated with the commercialization of the products in Europe and the United States to be contingent consideration that will be recorded as additional intangible assets in the periods that the contingency is resolved.

We have reviewed the tax positions taken, or to be taken, in its tax returns for all tax years currently open to examination by a taxing authority. As of December 31, 2009, the gross amount of unrecognized tax benefits exclusive of interest and penalties was $299,000. We have identified no uncertain tax positions for which it is reasonably possible that the total amount of unrecognized tax benefits will significantly increase or decrease within the 12 months ending December 31, 2010. We remain subject to examination until the statute of limitations expires for each respective tax jurisdiction. A reconciliation of beginning and ending amount of our unrecognized tax benefits is as follows:

Non-current deferred tax liability	($	1,546	)	($	1,260	)

We have assessed the need for a valuation allowance against our deferred tax assets and concluded that a valuation allowance against substantially all deferred tax assets is warranted at December 31, 2009 and 2008 because, based on the weight of available evidence, we believe it is more likely than not that such assets will not be realized. In reaching this conclusion, we evaluated all relevant criteria including the existence of temporary differences reversing in the carryforward period. The valuation allowance against these deferred tax assets may require adjustment in the future based on changes in the mix of temporary differences, changes in tax laws, and operating performance.

As of December 31, 2009, we have net operating loss carryforwards in the United States of $1.8 million that begin to expire in 2028. We also have state net operating loss carryforwards of $2.3 million that expire at various times beginning in 2013 through 2029. In addition, we have net operating loss carryforwards in France of $2.0 million that have no expiration, Japan of $1.2 million that begin to expire in 2013 and Italy of $5.0 million of which $0.6 million does not expire and $4.4 million begin to expire in 2013. We also have federal research and development tax credit carryforwards of approximately $0.5 million and state tax credit carryforwards of approximately $0.4 million that are available to reduce future tax liabilities, which expire at various dates beginning in 2011 through 2029. Included in the net operating loss carryforwards are stock option deductions of approximately $0.1 million. The benefit of these tax deductions will be credited to additional paid-in capital upon being realized. Ownership changes, as defined by Internal Revenue Code, may limit the amount of net operating losses and research and experimentation credit carryforwards that can be utilized annually to offset future taxable income and taxes payable.

We are not currently under audit in any tax jurisdictions.

We were examined by the Internal Revenue Service (IRS) for our 2004 and 2005 income tax returns. In 2007 the IRS proposed and we agreed to a final adjustment to the previously reported returns resulting in a payment of $0.4 million in April 2007, which amount was included in accrued expenses as of December 31, 2006. We were examined by the German federal tax authority in 2007, for our 2004, 2005, and 2006 tax returns. The German federal tax authority proposed and we agreed to a final adjustment to the previously reported returns resulting in an assessment of $0.3 million in 2007, which provision had been previously made as of December 31, 2006.

As of January 1, 2010, a summary of the tax years that remain subject to examination in our most significant tax jurisdictions are:

11. Stockholders’ Equity

Stock Award Plans

Under our 1997, 1998, 2000, and 2004 stock option plans, we authorized for the granting of options in the form of incentive stock options or nonqualified options to employees, directors, and consultants to purchase up to 1,688,702 shares of common stock. The stock options provide the holder the right to purchase common stock at a specific exercise price and the expected term will not exceed ten years. Incentive stock options are required to be issued at not less than fair market value at the date of the grant and generally vest over four or five years. The term of the options is determined by our Board of Directors but in no event will exceed ten years from date of grant, except with respect to one non-qualified option issued under our 1997 stock option plan.

In May 2006 we approved a 2006 Stock Option and Incentive Plan (the 2006 Plan), which became effective upon the initial public offering. In June 2009, we amended the 2006 Plan to increase the aggregate pool of available shares from 750,000 to 1,500,000 of common stock. The plan allows for granting of incentive stock options, non-qualified stock options, stock appreciation rights, restricted stock units, unrestricted stock awards, and deferred stock awards to our officers, employees, directors, and consultants. We have reserved for issuance of an aggregate of 1,500,000 shares of common stock under the 2006 Plan. In connection with the adoption of the 2006 Plan, no further option grants are permitted under the 1997, 1998, 2000, and 2004 stock option plans and any expirations, cancellations, or terminations under the previous plans are available for issuance under the 2006 Plan. We may satisfy awards upon exercise of stock options or RSUs with either newly issued or treasury shares. The total number of shares currently authorized for stock award plans is 3,118,003 of which approximately 221,513 remain available for grant as of December 31, 2009.

We account for stock options issued to non-employees using the fair value method. We compute the fair value of non-employee stock options using the Black-Scholes option-pricing model using an appropriate volatility factor and record the fair value of non-employee stock options as expense over either the vesting term of the option or the service period with the following assumptions:


	2008		2007
Dividend yield	0.0	%	0.0	%
Volatility	57.0	%	65.0	%
Risk-free interest rate	3.5	%	4.7	%
Weighted average expected option term (in years)	2.0		3.5

We recorded approximately ($8,000) during 2008, and $9,000 during 2007 of compensation (credits) expense related to stock options granted to non-employees. There were no unvested options to non-employees in 2009.

Restricted Stock Units

Beginning in 2006, we also issue restricted stock units as an additional form of equity compensation to our employees, officers, and directors, pursuant to our stockholder-approved 2006 Plan. RSUs entitle the grantee to an issuance of stock at no cost and generally vest over a period of time determined by our Board of Directors at the time of grant based upon the continued service to the Company. Unvested RSUs are forfeited and canceled as of the date that employment or service to the Company terminates. RSUs are settled in shares of our common stock upon vesting. We may repurchase common stock upon our employees’ vesting in RSUs in order to cover any minimum tax withholding liability as a result of the RSUs having vested. During the year ended December 31, 2009, we repurchased 43,281 of our $0.01 par value common stock at a per-share price of $3.80 and an aggregate purchase price of approximately $165,000. During the year ended December 31, 2008, we repurchased 23,432 of our $0.01 par value common stock at a per-share price of $2.84 and an aggregate purchase price of approximately $67,000. The value of the shares represented the amount required to satisfy the employees’ minimum obligations with respect to withholding taxes in connection with the vesting of shares of RSUs.

A summary of our RSU activity, which is subject to fair value accounting requirements, is as follows:


	Shares		Weighted Average Grant Date Fair Value
Balance outstanding at December 31, 2007	247,935		$	6.24
Granted	387,536		$	3.46
Vested(1)	(65,439	)	$	6.20

Canceled	(18,072	)	$	3.72

Balance outstanding at December 31, 2009	547,533		$	3.60

(1)	The number of RSUs vested includes the shares that we withheld on behalf of employees to satisfy minimum statutory tax withholding requirements.

The fair values of the RSUs that vested during 2009, 2008, and 2007 were $0.6 million, $0.4 million, and $0.2 million, respectively.

F-28

Employee Stock Purchase Plan

On July 13, 2009, our Board of Directors elected to terminate our Employee Stock Purchase Plan effective following the six-month offering period ending July 31, 2009. Our employee stock purchase plan had enabled eligible employees to purchase shares of our common stock. Eligible employees could purchase shares during six-month offering periods commencing on February 1 and August 1 of each year at a price per share equal to 90 percent of the fair market value of our common stock on the last date of each six-month offering period. Participating employees could elect to have up to ten percent of their base pay withheld and applied toward the purchase of such shares. The rights of participating employees terminate upon voluntary withdrawal from the plan at any time or upon termination of employment. On February 1, 2009, 10,698 shares were purchased at a purchase price of $1.91 per share. On July 31, 2009, 7,680 shares were purchased at a purchase price of $3.11 per share.

12. Profit-Sharing Plan

We offer a 401(k) profit-sharing plan (the Plan) covering eligible U.S. employees to make tax deferred contributions, a portion of which are matched by us. We may make discretionary matching contributions to the Plan in an amount determined by our Board of Directors. Company contributions vest ratably over six years of employment and amounted to approximately $0.1 million for 2009, $0.2 million for 2008, and $0.3 million for 2007.

13. Restructuring Charges

In September 2007, we entered into termination agreements with two former distributors in Europe. The termination fee payments amounted to $1.1 million in total, including $0.7 for contractual obligations associated with termination agreements with our former distributor in Italy. No further costs are expected to be incurred with respect to these agreements.

In 2008, we initiated reductions in force of 32 and eight employees in the first and third quarters, respectively. We incurred $0.4 million of severance charges related to the reductions in force in 2008, of which $0.1 million was paid in February 2009. No further costs are expected to be incurred with respect to these reductions in force.

In March 2009, we incurred $1.8 million of one-time restructuring charges, related to the termination of our Biomateriali subsidiary’s distribution agreement with Edward Lifesciences as discussed in Note 3.

The components of the restructuring charges are as follows:


	Year ended December 31,

14. Segment and Enterprise-wide Disclosures

The FASB establishes standards for reporting information regarding operating segments in annual financial statements. Operating segments are identified as components of an enterprise about which separate, discrete financial information is available for evaluation by the chief operating decision-maker in making decisions on how to allocate resources and assess performance. We view our operations and manage our business as one operating segment. No discrete operating information other than product sales is prepared by us, except by geographic location, for local reporting purposes.

We sell products in three product categories; Endovascular, Vascular, and General Surgery, and have also derived a limited amount of revenue from manufacturing devices under private label manufacturing arrangements. Net sales in these product categories were as follows:


	Year ended December 31,
	2009		2008		2007

OEM		444		273		0

Net sales	$	50,908	$	48,720	$	41,446

Most of our revenues were generated in the United States, Europe, and Japan, and substantially all of our assets are located in the United States. We analyze our sales using a number of approaches, including sales by legal entity. LeMaitre Vascular GmbH, our German subsidiary, records all sales in Europe and to distributors worldwide, excluding sales in France (LeMaitre Vascular SAS); Italy (LeMaitre Vascular S.r.l.); Japan, Korea, and Taiwan (LeMaitre Vascular GK); and private label manufacturing sales (Biomateriali S.r.l.). Net sales to unaffiliated customers by legal entity were as follows:

16. Fair Value Measurements

The fair value accounting guidance requires that assets and liabilities carried at fair value be classified and disclosed in one of the following three categories:

•

Level 1—Quoted prices in active markets for identical assets or liabilities

•

Level 2—Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.

•

Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs.

Our available-for-sale investments are subject to fair value accounting which includes cash equivalents and short-term investments. The following table details the fair value measurements within the fair value hierarchy of our financial assets (in thousands) as of December 31, 2009, which were valued using Level 2 inputs (significant and observable assumptions) as follows:


Corporate bonds	$	450
Asset backed securities		358

	$	808

As of December 31, 2009, we had cash equivalents in repurchase agreements and US treasury notes that were valued using Level 1 inputs (quoted market prices for identical assets) as follows:


Repurchase agreements	$	12,300
US Treasury Notes		7,499
