First Claim
Patent Images
1. A bifurcated endovascular prosthesis comprising:
- a first tubular graft exhibiting a lateral opening;
a compressible and self-expandable mesh support attached to substantially the entire outside surface of said first tubular graft, anda second tubular graft attached at one end to said lateral opening.

Abstract
A small bifurcated graft is described which may be placed in each hypogastric artery to maintain patency both to it and to the external iliac artery and the leg below. The purpose is to maintain flow to the hypogastric artery while stenting the whole of the aorta-iliac system with endovascular overlapping straight tube grafts. Without this bifurcated device, aorto-iliac stenting would result in colonic ischemic.

9. A method for the treatment of disease in an aorto-iliac segment compromising:
-
percutaneously introducing and placing a bifurcated arterial prosthesis into a hypogastric artery, and reconstructing contiguous portions of the aorto-iliac segment using percutaneously introduced tube grafts which are made to overlap in their final resting positions.

10. A method for introducing and positioning a bifurcated hypogastric arterial graft in a hypogastric artery comprising:
-
introducing a catheter containing said graft into the femoral artery opposite the target hypogastric artery; feeding said catheter containing said graft around the aortic bifurcation; positioning said catheter in a predetermined location within the hypogastric artery, and releasing said graft from said catheter. - View Dependent Claims (11)
