摘要：
A catheter for delivery of sclerosant to a tubular member or vein of the body to cause ablation. The catheter has one or more balloons located near the distal end to enhance effectiveness of the sclerosant and prevent its delivery to the deep venous system. The catheter has an orifice located near the distal end of the catheter to direct the sclerosant into the vessel and one or more effluent openings to provide for removal of the sclerosant fluid. A heating member such as an electrical resistance element, a Laser probe, or an RF electrode located within the catheter lumen or on the outside of the catheter shaft heats the sclerosant fluid to improve its ablation effectiveness.
