Abstract
A collapsible medical device and associated method for grafting a lumen of selected organs and vessels, wherein the medical device is shaped from a shape memory fabric. The device is preferably made from a continuous tubular fabric and each end terminates with an open end for passage there through. Each end further includes a securing member attached to an outer perimeter of the end, wherein a substantial plane formed by the perimeter intersects the longitudinal axis of the tubular fabric at either an acute or obtuse angle. The fabric may be heat treated within a mold in order to substantially set a desired shape of the device. The securing member may also attach to the end of a guide wire or delivery catheter, thereby allowing deployment and later retrieval after deployment of the device.
