A stent deployment system includes a catheter shaft, an expandable member mounted to the catheter shaft, and one or more stents or stent segments slidably positioned on the expandable member. The stent deployment system is adapted for deployment of stents or stent segments in very long lesions and in tapered and curved vessels. The stent deployment system facilitates slidable movement of a stent in a distal direction relative to the expandable member while inhibiting slidable movement in a proximal direction relative to the expandable member.

Cette invention concerne un système de déploiement de stents comprenant une tige de cathéter, un élément extensible monté sur la tige de cathéter et un ou plusieurs stents ou segments de stents disposés coulissants sur l'élément extensible. Le système de déploiement de stents est conçu pour déployer des stents ou des segments de stents dans de très longues lésions et dans des vaisseaux coniques et courbes. Ce système de déploiement de stents permet à un stent de coulisser plus facilement dans une direction distale par rapport à l'élément extensible tout en l'empêchant de coulisser dans une direction proximale par rapport à l'élément extensible.
