The Closure procedure is a minimally invasive treatment which often results in varicose veins and other painful symptoms. Closure procedure provides a less-invasive alternative to vein stripping by closing the diseased vein instead. The Closure catheter, which is positioned into the diseased vein, delivers radiofrequency (RF) energy to the vein wall. As result the vein wall is heated, causing the collagen in the wall to shrink and the vein to close.
