Zusammenfassung:	PCT No. PCT/US94/12050 Sec. 371 Date Jun. 18, 1997 Sec. 102(e) Date Jun. 18, 1997 PCT Filed Oct. 20, 1994 PCT Pub. No. WO95/11055 PCT Pub. Date Apr. 27, 1995A 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 a single layer sheath retaining sleeve means for retaining the stent in its delivery configuration attached to a slipping sleeve means for releasing the stent to self-expand. A balloon may optionally be used to seat the stent in the vessel after self-expansion. The stent may also optionally be retained by water soluble or swelling bands.
