A catheter for delivery of prosthetic stent segments comprises a separator tube having a one-way grip structure near a distal end thereof. The stent segments are delivered to a treatment region on a balloon. To select a number of distal stent segments for deployment, the separator tube is advanced distally over proximal stent segments. Proximal retraction of the separator tube pulls the engaged segment(s) proximally to separate proximal segments from distal segments, freeing the distal segments for deployment.

L'invention concerne un cathéter pour délivrer des segments de stent prothétiques qui comprend une tubulure de séparation ayant une structure de saisie simple près d'une extrémité distale de celle-ci. Les segments de stent sont délivrés sur une région de traitement sur un ballonnet. Pour choisir un nombre de segments de stent distaux à déployer, la tubulure de séparation est avancée distalement sur des segments de stent proximaux. Une rétractation proximale de la tubulure de séparation tire le ou les segments engagés proximalement pour séparer des segments proximaux des segments distaux, libérant les segments distaux à déployer.
