The invention relates to stent delivery system (500) and method. A stent delivery system includes a self-expandable stent (501) and a sheath (502) configured to surround the stent in a compressed state. A catheter (504) is adapted to deliver the stent and the sheath into a predetermined deployment site. A balloon (503) is mounted on a tip of the catheter and is inflated to expand the stent. Upon deployment of the stent, the sheath is trapped between the stent and a vessel. |
