摘要:
A method of treating a varicose vein involves inserting the distal portion of an intraluminal device into a varicose vein, wherein the device includes an elongated outer sheath and an expandable expansion member at the distal end of the outer sheath. The method also involves relatively moving the distal and proximal ends of the expandable spiral expansion member to reduce the distance between the distal and proximal ends of the expansion member and cause the expansion member positioned inside the varicose vein to outwardly expand to an expanded expansion member comprising a plurality of contact members in contact with the inner wall of the varicose vein. The method further includes axially moving the expanded expansion member while the contact members are in contact with the inner wall of the varicose vein and rotating the expanded expansion member during the axial movement.
