What is the VNUS Closure procedure?
The VNUS Closure procedure is the first minimally-invasive surgical treatment for venous reflux disease, which causes varicose veins. The Closure procedure uses radiofrequency (RF) energy to occlude, or close, the saphenous vein. A catheter is used to deliver heat to the vein wall. As the energy is delivered and the catheter is withdrawn, the vein wall is heated causing the collagen in the wall to shrink and the vein to close. Once the diseased vein is closed, blood is re-routed to other healthy veins.
