Abstract
Abstract A minimally invasive percutaneous ligation method for treating a varicose vein is provided. The junction between the varicose vein and the deep veins of the patient's leg are first ligated by conventional techniques. Then, a sterile closure is pierced through a skin layer adjacent to a varicose region of the vein such that at least a portion of the sterile closure remains external to the skin layer. The varicose vein is at least partially obstructed with the sterile closure to promote intentional scarring of the vein. Finally, the sterile closure is removed back through the skin layer after a sufficient amount of scarring of the vein has occurred. The sterile closure may comprise a surgical staple, a pin or a screw.
