The VNUS Closure procedure is a minimally invasive treatment alternative with less pain and less bruising when compared to traditional vein stripping surgery and laser treatment. Using the Closure system, physicians close the diseased veins by inserting the Closure catheter into a vein and heating the vein wall using temperature-controlled RF energy. Heating the vein wall causes collagen in the wall to shrink and the vein to close. After the vein is sealed shut, blood then naturally reroutes to healthy veins.
Venous reflux or venous insufficiency develops when the valves that usually keep blood flowing out of your legs become damaged or diseased.
