A low profile occlusion device for percutaneous or direct transcutaneous placement into a vein or other tubular vessel of the body. Two wires form one or more loops having a thin cover disposed between them. The loop forms a beveled angle within the blood vessel and the cover prevents blood flow through the vessel. An additional loop can be present to prevent device embolization or device migration. The occlusion device is delivered to a vein such as an incompetent perforator vein or other incompetent vein through a small flexible sheath. Ultrasound guidance is used to position the occlusion device which can be repositioned within the vessel if necessary.
