Concerned Physicians Urge Total Vein to Establish Legal Defense Fund

HOUSTON, TX--(Marketwire - November 20, 2008) - On September 8, 2008, VNUS Medical Technologies, Inc. brought a patent infringement lawsuit against Total Vein Systems, a small privately held company with 12 employees based in Houston, Texas. Since that time, Total Vein Systems has received countless phone calls from physicians around the country offering their personal as well as financial support in the lawsuit with VNUS. In response to these numerous requests and rising legal costs, Total Vein Systems is pleased to announce that it plans to establish a TVS LEGAL DEFENSE FUND TRUST.

The patent lawsuit brought by VNUS does not allege that TVS has been selling radiofrequency catheters like the ones sold by VNUS for the endovenous treatment of varicose veins -- TVS does not sell such devices. Instead, VNUS alleges that TVS has somehow infringed five VNUS patents by selling a number of a unpatented commodity medical supplies, including unpatented laser fibers, unpatented micro-introducer kits, unpatented procedure packs, and even unpatented guidewires.

TVS believes that the VNUS allegations of patent infringement are without merit. We also believe that the VNUS lawsuit is an improper attempt to raise prices on generic, unpatented medical supplies, thereby promoting VNUS's more expensive radiofrequency catheter products.

As we begin the costly process of defending our company in United States Federal District Court in San Francisco, we thank all of the physicians and vein clinics that have supported us since we began operations in 2004.

Total Vein Systems remains dedicated to providing physicians and vein centers with the highest quality products at competitive prices.
