The ClosureFast™ procedure

The ClosureFast™ procedure is a minimally invasive treatment option for varicose veins and venous reflux.

The ClosureFast catheter is inserted into the vein through a tiny incision at or around the knee. Guided by ultrasound imaging, the physician treats a 7 cm segment of vein with a 20-second burst of radiofrequency energy (heat), causing the vessel to shrink around the catheter. The physician withdraws the catheter, treating each segment until the entire length of the vein has been sealed. An average 45 cm length vein can be treated in this manner in just three to five minutes.

Unlike painful vein stripping surgery or laser ablation, the catheter delivers uniform, consistent heat to each segment and temperatures do not exceed 120° C. As a result, the ClosureFast procedure causes less bruising and allows for rapid patient relief and recovery. The ClosureFast procedure is commonly performed in-office or same-day hospital setting.
