APPARATUS AND METHODS FOR DEPLOYMENT OF CUSTOM-LENGTH PROSTHESES

摘要

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.
