Abstract
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.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
44 words
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, and a second tubular graft attached at one end to said lateral opening.
Claim 2
Dependent Claim
44 words
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, and a second tubular graft attached at one end to said lateral opening.
Claim 3
Dependent Claim
28 words
The bifurcated endovascular prosthesis according to claim 1, wherein said first and second grafts are made of a material selected from the group consisting of dacron and PTFE.
Claim 4
Dependent Claim
15 words
The bifurcated endovascular prosthesis according to claim 1, wherein the support comprises a metallic mesh.
Claim 5
Dependent Claim
17 words
The bifurcated endovascular prosthesis according to claim 1 further comprising a platinum wire situated around said opening.
Claim 6
Dependent Claim
18 words
The bifurcated endovascular prosthesis according to claim 1, wherein the length of said first graft is 4-5 centimeters.
Claim 7
Dependent Claim
18 words
The bifurcated endovascular prosthesis according to claim 1, wherein the length of said second graft is 0.5-1.5 centimeters.
Claim 8
Dependent Claim
14 words
The bifurcated endovascular prosthesis according to claim 1, wherein said first graft is tapered.
Claim 9
Dependent Claim
17 words
The bifurcated endovascular prosthesis according to claim 1, further comprising a wire extending from said second graft.
Claim 10
Independent Claim
47 words
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.
Claim 11
Independent Claim
47 words
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.
Claim 12
Independent Claim
59 words
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.
Claim 13
Independent Claim
59 words
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.
Claim 14
Dependent Claim
14 words
The method according to claim 10, further comprising expanding said graft with balloon angioplasty.
