Intraluminal graft

摘要

An intraluminal graft (10) includes a tubular graft body (11) formed of a film or fabric which is reinforced along its length by a plurality of separate spaced apart malleable wires (17). Each of the wires (17) has a generally closed sinusoidal or zigzag shape. A wire (17) located adjacent to one end of the graft body (11) has alternate crests or apices that project beyond that end of the graft body (11). The graft (10) may be inserted intraluminally into the body of a patient in a collapsed condition within a catheter. Once positioned to bridge across an aneurysm within the patient's arterial system the graft (10) may be expanded radially by a balloon to bridge the aneurysm and occlude the aneurysmal sack.
