ClosureFast™ Treatment






ClosureFast™ System

The ClosureFast™ procedure is a minimally invasive treatment that uses radiofrequency (RF) energy to effectively treat patients with varicose veins or chronic venous insufficiency (CVI). Because the valves in the legs cannot be repaired, the only alternative is to re-route the blood flow from the diseased veins to the healthy veins.

To do this, a vein specialist inserts a catheter into the diseased vein through a tiny incision below the knee. Guided by ultrasound imaging, a vein specialist will treat the vein in 7 cm segments for 20 seconds each. The catheter delivers consistent and uniform heat to contract the collagen in the vein walls, causing them to collapse and close. After the vein is sealed shut, blood is then naturally redirected to healthy veins. The treated vein then becomes fibrous tissue and will gradually be absorbed into surrounding tissue.
