Physicians Hail VNUS Device for Closing Diseased Perforating Veins

ClosureRFS Stylet 'Ideal' for Treating Condition Affecting Four Million


SAN JOSE, Calif., Nov. 1 /PRNewswire-FirstCall/ -- VNUS(R) Medical Technologies, Inc. (Nasdaq: VNUS), a worldwide leader in medical devices for the minimally invasive treatment of venous reflux disease, today announced the widespread success and rapid market growth of the VNUS ClosureRFS(TM) Stylet, an endovenous radiofrequency (RF) ablation catheter currently employed by more than 500 physicians to treat a specific varicose vein-related condition in the lower leg. The ClosureRFS Stylet is the only endovascular ablation device specifically cleared by the FDA for the treatment of incompetent perforating veins or IPVs, which can produce calf and ankle swelling and skin ulcerations in about four million Americans. Over 15,000 minimally invasive ClosureRFS procedures have been performed worldwide to heat and close diseased perforators.

"I have performed over 700 procedures with the ClosureRFS Stylet, and I consider it a giant step forward in our treatment of severe venous insufficiency," said Dr. Charles J. Rodman, MD., of Beaumont, Texas. "Our patients are primarily those with advanced venous disease, and they almost always present with large, incompetent perforating veins that unquestionably must be addressed in the course of treatment. The RFS Stylet is simple to use and small enough to handle with precision, and among physicians like myself treating this patient population, I believe there's uniform agreement that it's the best device available."

"ClosureRFS is absolutely the best way of closing perforators, with none of the drawbacks of other techniques we have researched," said Dr. Mark Whiteley, vascular surgeon and director of The Whiteley Clinic in Surrey, England. "The beauty of the RFS Stylet is that the ultrasound lets you know exactly where you are at all times during the procedure, so it reduces or eliminates the risk of complications, and you're certain of getting successful ablation of the vein exactly at the point you want it. Perforator incompetence has proven to be a common cause of varicose vein recurrence, even in patients whose truncal reflux disease has been successfully treated, so we know that where the condition exists, it must be treated -- and ClosureRFS is clearly the device of choice."

"In order to provide total vein care for venous insufficiency, I think it's vital to address perforating veins as well as the saphenous vein, because almost all of the leg ulcers and post-treatment recurrences we see are associated with diseased perforators," said Thomas Pester, MD., of El Paso, Texas. "The ClosureRFS Stylet is an ideal device for dealing with this issue -- it's very easy to use, the results are quite good and the patients are comfortable with it. I would recommend it to every physician treating patients with venous reflux disease."

ClosureRFS can be performed either as a primary outpatient procedure or as an adjunct to saphenous vein ablation procedures. VNUS has launched an improved version of the ClosureRFS Stylet, which now includes an integrated cable and a new streamlined hub designed for easier use and better ergonomics. For physicians seeking to treat the whole spectrum of venous pathology in managing patients with venous disease, the improved ClosureRFS Stylet is the only endovascular ablation device specifically cleared by the FDA for the treatment of incompetent perforator veins.

"The ClosureRFS Stylet has proven itself as a vital tool for physicians treating the perforator incompetence often seen in patients with advanced venous disease, and we're pleased with how quickly and enthusiastically it has been adopted by the medical community," said Brian E. Farley, President and CEO of VNUS. "This latest version of the RFS Stylet represents a major step forward, particularly in ease of use for physicians, and it addresses a rapidly growing market for the treatment of this form of venous insufficiency."


Founded in 1995 and headquartered in San Jose, California, VNUS Medical Technologies (Nasdaq: VNUS) is a worldwide leader in medical devices for the minimally invasive treatment of venous reflux disease, a progressive condition that causes the varicose veins afflicting 25 million Americans. The pioneering company in the field, VNUS now offers the ClosureFAST system, which consists of a proprietary radiofrequency (RF) generator and proprietary disposable endovenous catheters and devices to close diseased veins through the application of temperature-controlled RF energy.
