Abstract

A delivery system and device for re-lining bodily vessels. A stent is attached to a distal end of a tubular lining made of biocompatible material and loaded into a hollow atraumatic tip. A semi-rigid shaft connects the atraumatic tip to a stopper and runs through the center of the tubular lining. The proximal end of the tubular lining is attached to a sliding hub. Optionally, a balloon is positioned near the stent in fluid communication with the shaft. The assembled device is introduced into a bodily vessel following an endarterectomy or atherectomy procedure. The atraumatic tip is delivered to a predetermined location and upon reaching that destination, the stent is released from the tip to expand against the vessel wall. If a balloon is utilized, it is inflated to ensure that the stent is fully deployed within the vessel. The balloon is then deflated arid the tip and shaft are pulled through the expanded stent and tubular lining. The sliding hub is cut off of the tubular lining and the proximal anastomosis is completed.
