Abstract:
A device for fully or partially closing a blood vessel that has a wall, an outer surface and a lumen extending therethrough, said device comprising:a catheter that is advanceable into the lumen of said blood vessel;an elongate, resilient member having a distal end and at least one vessel engaging member formed thereon, said elongate member being biased to a coiled configuration;said elongate member being initially disposed in said catheter and subsequently deployable out of said catheter after the catheter has been advanced into the lumen of said blood vessel such that a) the elongate member passes distal-end-first from the lumen of the blood vessel outwardly through the wall of the blood vessel, b) the elongate member advances at least part of the way around the outer surface of the blood vessel without re-penetrating the wall of the blood vessel, and c) said at least one vessel engaging members engages the outer surface of the blood vessel and d) the bias of the elongate member causes it to assume a coiled configuration thereby causing the lumen of the blood vessel to become at least partially closed.
