First Claim
Patent Images
1. An aortic graft for intraluminal delivery to repair an abdominal aortic aneurysm in an aorta having two iliac arteries associated therewith at an aortic bifurcation, comprising:
- a tube having first and second ends, an intermediate portion disposed between the 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, the intermediate portion of the tube being not substantially radially expandable, and the first end of the tube being radially expandable;
a first means for securing the first end of the tube to the aorta, the first securing means having a first diameter which permits intraluminal delivery of the first securing means into the aorta and the first securing means having a second, expanded diameter, to secure the first end of the tube to the aorta; and
a second means for securing the second end of the tube at the aortic bifurcation, the second means for securing being disposed at the second end of the tube.
