What are the advancements of the ClosureFAST™ procedure?
The VNUS ClosureFAST catheter uses bipolar radiofrequency energy to deliver thermal energy into the vein wall. The vein is heated and maintained at a precise temperature. The passage of heat through the vein wall shrinks the vessel and causes it to collapse around the catheter. When the catheter is withdrawn, the vein remains closed. Among other advances, the longer ClosureFAST™ heating element can treat a seven-centimeter length of vein all at once in just 20 seconds. This allows the physician to treat the full length of saphenous vein in just 3-5 minutes – up to 6 times faster than the previous Closure technology.
