The VNUS Closure® procedure is a minimally
invasive treatment alternative to traditional vein stripping surgery
for venous reflux, a common underlying cause of varicose veins.
The Closure System was cleared for marketing in the US in March
1999. The Closure procedure is becoming increasingly popular. The procedure is performed by placing a very small tube (catheter) into the vein to deliver radiofrequency energy to the vein wall, causing it to collapse and seal shut. Once the diseased vein is sealed, healthy veins will take over and redirect the blood flow.
The procedure is minimally invasive and can be performed under local anesthesia in a doctor's office. Patients have reported feeling little, if any, pain during the procedure and most return to their normal activity within a day. Some common side effects may include temporary tenderness and numbness.

Within 1-2 weeks after the procedure, patients report good cosmetic outcomes and noticeable improvement in their symptoms with little to no pain, scarring, or bruising.
The Closure procedure is covered by most insurance companies when deemed medically necessary.
As with other treatments, the Closure procedure will not prevent new varicose veins from developing in alternate veins.
