MANSFIELD, Mass.--(BUSINESS WIRE)--Covidien (NYSE:COV), a leading global provider of healthcare products, today announced the five-year results of the ClosureFast™ Long-Term European Multi-Center Study in patients with Chronic Venous Insufficiency (CVI). This study evaluates the five-year outcomes of a minimally invasive endovascular therapy for treatment of CVI. The ClosureFast Study was conducted prospectively at eight centers in Europe. The Venefit™ procedure (using the ClosureFast radiofrequency ablation catheter) was used to treat 295 lower limbs in 225 patients diagnosed with superficial venous reflux, the underlying cause of varicose veins and CVI. This progressive medical condition affects the veins in the leg and compromises their ability to carry blood back to the heart. This is a worldwide issue and, in fact, impacts over 30 million Americans in the United States alone.1 If left untreated, varicose veins can advance to CVI, which, in severe cases, may result in lower leg pain, skin damage, and leg ulcerations.
