ENDOLUMINAL ANGEBRACHTES VASKULARES TRANSPLANT

摘要

A delivery system and device for re-lining bodily vessels. A stent (22) is attached to a distal end of a tubular lining made of biocompatible material and loaded into a hollow atraumatic tip (32). A semi-rigid shaft (30) connects the atraumatic tip to a stopper (36) and runs through the center of the tubular lining (20). The proximal end of the tubular lining (20) is attached to a sliding hub (28). Optionally, a balloon (34) is positioned near the stent in fluid communication with the shaft. The assembled device is introduced into a bodily vessel (40) following an endarterectomy or atherectomy procedure. The atraumatic tip (32) is delivered to a pre-determined location and upon reaching that destination, the stent (22) is released from the tip (32) to expand against the vessel wall. If a balloon (34) is utilized, it is inflated to ensure that the stent (22) is fully deployed within the vessel. The balloon (34) is then deflated and the tip (32) and shaft (30) are pulled through the expanded stent (22) and tubular lining (20). The sliding hub (28) is cut off of the tubular lining and the proximal anastomosis is completed.
