The VNUS Closure™ Procedure
Radiofrequency (RF) endovenous ablation is a minimally invasive procedure for treating venous reflux disease, using RF to heat and seal diseased veins thereby reducing or eliminating existing varicose veins. With the VNUS ClosureFAST™ catheter, the only RF ablation device on the market today for the treatment of venous reflux, radiofrequency energy is delivered through a heating element seven centimeters long to heat the collagen within the vein walls and cause the shrinkage and collapse of the vessel.
The Closure™ procedure is generally performed using local anesthesia, typically in a physician’s office or an outpatient surgical facility. The ClosureFAST catheter is inserted into the vein through a tiny incision below the knee. Guided by ultrasound imaging, the physician treats each 7cm. segment of vein with a 20-second burst of RF energy, causing the vessel to shrink around the catheter. The physician withdraws the catheter, treating each segment until the entire vessel has been sealed. An average 45cm length vein can be treated in this manner in three to five minutes.
In a clinical trial comparing Closure to laser, patients treated with Closure experienced less pain, less bruising and fewer complications with the Closure system.1 And one-year clinical data has shown the ClosureFAST™ catheter to be more than 97.4% effective in preventing reflux recurrence.2
