Abstract

Disclosed is an ablation method and apparatus used to close veins for treatment of venous insufficiency disease. The apparatus includes a catheter body, and an ablation electrode array disposed between the balloons. According to the disclosed method, the catherter is introduced into the vein to be treated and the balloons are distented. Blood is flushed and aspirated from the site between the balloons. RF power is applied to the electrode array, causing scarring of the vessel walls and eventual sealing of the vein.
