The ClosureFast™ procedure uses radiofrequency energy to precisely and effectively treat patients suffering from chronic venous insufficiency (CVI).
The ClosureFast™ catheter precisely heats a 7 cm vein segment (or 3 cm for shorter, refluxing vein lengths) in one 20-second interval.
The heat provided by the catheter shrinks and collapses the target vein, creating a fibrotic seal and occluding the vessel.
