Abstract
Abstract Endovascular grafting system having a capsule catheter (12) comprising a flexible elongate tubular member (16) having proximal and distal extremities and a capsule (36) mounted on the distal extremity of the tubular member (16). The capsule (36) is generally cylindrical in shape and is formed of a helical wrap of a metal ribbon (39). The wraps are bonded into a unitary capsule permitting bending of said unitary capsule. A graft is disposed within the capsule (36). The graft is comprised of a tubular member having proximal and distal ends. Hooks are secured to the proximal and distal ends of the tubular member and face in a direction outwardly towards the inner wall of the capsule. A push rod is disposed within the capsule catheter (12) and engages the graft whereby upon relative movement between the push rod and the capsule catheter, the graft can be forced out of the capsule. <IMAGE>
