What is the Endovenous Radio Frequency (Closure®) procedure?
The Closure procedure is a minimally invasive treatment for superficial venous reflux. VNUS, the company that developed this device, got FDA approval in 1999. Although they like to credit themselves with being the first to use heat to close the saphenous vein, in Europe a surgeon presented a paper on the use of laser to close the saphenous vein in 1989.
