ABSTRACT:
A delivery system for implantation of a self-expanding stent in a vessel is consists of an elongate flexible catheter for delivering a self-expanding stent to a predetermined location in a vessel. The stent surrounds the flexible catheter near its distal end and is held in a delivery configuration where the stent has a reduced radius along its entire axial length by a stent retaining and release means. The stent retaining and release means is either one or more slipping sleeves which either contain the stent themselves or form a waterproof chamber with the stent being contained by water soluble bands or swelling bands. The stent retaining and release means can also be a pair of sleeves connected to hydraulic pistons, or a pair of sleeves connected to push/pull wires.
