  • a tube having a longitudinal axis, first and second ends, and a wall surface disposed between the two ends, at least a portion of the tube adapted to be disposed within the abdominal aortic aneurysm;

    means for securing the first end of the tube to the aorta, the securing means having a first diameter which permits intraluminal delivery of the securing means into the aorta and the securing means having a second, expanded diameter, to secure the first end of the tube to the aorta; and

    a means for sealing the second end of the tube within the aortic bifurcation, the sealing means being at least one deformable, malleable wire associated with the second end of the tube by the at least one wire being woven into the wall surface of the second end of the tube and being disposed substantially coplanar with the wall surface of the tube, the at least one wire in the second end of the tube having a first cross-sectional configuration which permits intraluminal delivery of the tube and the means for sealing within the aortic bifurcation, and a second enlarged cross-sectional configuration, wherein the at least one wire and the second end of the tube conform to, and sealingly engage, the interior surface of the aortic bifurcation.
