Terumo Cardiovascular Systems (Terumo CVS) has filed a patent infringement complaint in Germany against two affiliates of Maquet Cardiovascular LLC: Maquet GmbH & Co. KG and Maquet Vertriebs und Service Deutschland GmbH.
The complaint alleges that two Maquet products, Vasoview® 6 and Vasoview® 7 Endoscopic Vessel Harvesting Systems, infringe a patent for which Terumo CVS owns the rights in Germany. The complaint also requests an injunction against further sales of the product there.
Terumo Corporation is a premier global medical device company with annual sales of nearly three billion dollars for the year ending March 31, 2008. Founded in 1921, the company develops, manufactures and distributes world-class medical devices for use in cardiothoracic surgery, interventional procedures, transfusion medicine, and needle and syringe products.
Terumo CVS sells the VirtuoSaph(TM) Endoscopic Vessel Harvesting System in the United States. The VirtuoSaph system is 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.
