Abstract
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.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
120 words
A collapsible medical device, comprising a fabric including a plurality of woven strands, said device having a proximal end and a distal end, each end having attached thereto means for securing the woven strands, thereby inhibiting unraveling of the fabric, said device having a relaxed cylindrical configuration, wherein said relaxed cylindrical configuration includes a passageway extending through a central portion between each end, wherein a plane of at least one end intersects a longitudinal axis of said cylindrical configuration at an angle of at least one of acute and obtuse, the means for securing having means for attachment to a delivery device, said device further having a stretched collapsed configuration for percutaneous delivery through a channel in a patient's body.
Claim 2
Dependent Claim
120 words
A collapsible medical device, comprising a fabric including a plurality of woven strands, said device having a proximal end and a distal end, each end having attached thereto means for securing the woven strands, thereby inhibiting unraveling of the fabric, said device having a relaxed cylindrical configuration, wherein said relaxed cylindrical configuration includes a passageway extending through a central portion between each end, wherein a plane of at least one end intersects a longitudinal axis of said cylindrical configuration at an angle of at least one of acute and obtuse, the means for securing having means for attachment to a delivery device, said device further having a stretched collapsed configuration for percutaneous delivery through a channel in a patient's body.
Claim 3
Dependent Claim
24 words
The device according to claim 1 , wherein at least one end includes markers spaced a predetermined distance around an edge of said end.
