Stent delivery system and method using a balloon for a self-expandable stent

摘要

The invention relates to stent delivery system and method. A stent delivery system includes a self-expandable stent and a sheath configured to surround the stent in a compressed state. A catheter is adapted to deliver the stent and the sheath into a predetermined deployment site. A balloon 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.
