ANN ARBOR, Mich., April 4, 2008 /PRNewswire/ -- Terumo Cardiovascular Systems (Terumo CVS) announced yesterday that it is responding to a patent infringement complaint by Maquet Cardiovascular LLC.

Terumo CVS states that its policy and its practice are not to infringe on the valid intellectual property rights of any company. The VirtuoSaph system is protected by multiple Terumo patents.

"Frankly, we're surprised at this lawsuit as these patents are several years old and our product has been on the market for more than three years with great success," says Mark DiClemente, Vice President, Sales, Terumo Cardiovascular Systems. "Our competitor has only recently entered the vessel harvesting market through an acquisition."

Terumo CVS has sold the VirtuoSaph system in the United States since January 2005. The product is also distributed in Japan and Asia by Terumo Corporation and in Europe by Terumo's European subsidiary.

The VirtuoSaph system is used during coronary artery bypass grafting (CABG), the most common cardiac surgery procedure. During the procedure, the surgeon removes a healthy artery or vein from elsewhere in the body, most often the saphenous vein in the leg, and uses it to route blood around a blockage in a coronary artery. The VirtuoSaph system allows the surgical team to remove the saphenous vein using very small incisions. Endoscopic procedures have been shown to minimize scarring, morbidity and infection associated with traditional longitudinal incisions.
