NEW YORK, Nov 17, 2010 (BUSINESS WIRE) --
Covidien (NYSE:COV), a leading global provider of healthcare products, today announced that results from a prospective, multicenter study using the VNUS ClosureFAST(TM) catheter , demonstrated clinical efficacy and improvement in quality of life for patients. The ClosureFAST catheter is an endovenous radiofrequency (RF) ablation  catheter designed to heat and close diseased veins, the major underlying cause of varicose veins.
The results were presented at the American College of Phlebology's 24th Annual Congress in Orlando, Florida on November 5, and here today at the 37th Annual VEITH Symposium on Vascular and Endovascular Issues.
Alan Dietzek, M.D., Chief of Vascular Surgery and the Linda and Stephen R. Cohen Chair in Vascular Surgery at Danbury Hospital in Connecticut, presented three-year follow-up results of patients treated with the ClosureFAST catheter from a study conducted at 13 centers in the U.S. and Europe. Two-hundred sixty-seven greater saphenous veins  were evaluated at the follow-up and demonstrated a 93% occlusion rate using Kaplan-Meier analysis.
In addition to clinical efficacy, the study has shown a venous clinical severity score reduction at three-year follow up, which indicates an improvement in patients' relief of symptoms, such as pain or inflammation, from the baseline score at time of treatment.
These results were consistent with those presented this month for the seven European study sites by Professor Thomas M. Proebstle, M.D., PhD, of the Department of Dermatology, University of Mainz, Germany, and the University of PÃ©cs, Hungary, in his presentation titled, "Three Year Follow-Up After Radiofrequency Segmental Thermal Ablation of Great Saphenous Veins." The European study was presented at the American College of Phlebology.
"These study results continue to support and strengthen clinicians' confidence in the ClosureFAST technology and its effectiveness in treating millions of venous insufficiency patients who suffer from varicose veins," said Joe Woody, President, Vascular Therapies, Covidien.
