Abstract
Abstract An aortic graft for intraluminal delivery to repair an abdominal aortic aneurysm is provided with at least one wire which is woven into the distal, or lower, end of the graft, which wire permits the distal end of the graft to conform to, and sealingly engage, within the aortic bifurcation region of the aneurysm.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
166 words
A method for repairing an abdominal aortic aneurysm in an aorta having two iliac arteries associated therewith at an aortic bifurcation having an interior surface, comprising the steps of: (a) connecting an upper end of a tube to an expandable tubular member; (b) disposing the tube and tubular member upon a first catheter having a first expandable, inflatable portion with the tubular member disposed upon the first expandable, inflatable portion; (c) intraluminally delivering the tube, tubular member and first catheter to the aorta and disposing at least a portion of the tube within the abdominal aortic aneurysm; (d) expanding the first expandable, inflatable portion of the first catheter to expand the tubular member to force the tubular member radially outwardly into contact with the aorta to secure the tubular member and at least a portion of the tube within the aorta; and (e) securing a lower end of the tube within the aortic bifurcation, whereby the tube provides a fluid passageway through the abdominal aortic aneurysm.
Claim 2
Independent Claim
166 words
A method for repairing an abdominal aortic aneurysm in an aorta having two iliac arteries associated therewith at an aortic bifurcation having an interior surface, comprising the steps of: (a) connecting an upper end of a tube to an expandable tubular member; (b) disposing the tube and tubular member upon a first catheter having a first expandable, inflatable portion with the tubular member disposed upon the first expandable, inflatable portion; (c) intraluminally delivering the tube, tubular member and first catheter to the aorta and disposing at least a portion of the tube within the abdominal aortic aneurysm; (d) expanding the first expandable, inflatable portion of the first catheter to expand the tubular member to force the tubular member radially outwardly into contact with the aorta to secure the tubular member and at least a portion of the tube within the aorta; and (e) securing a lower end of the tube within the aortic bifurcation, whereby the tube provides a fluid passageway through the abdominal aortic aneurysm.
Claim 3
Dependent Claim
20 words
The method of claim 1, including the step of not piercing the aorta by the expansion of the tubular member.
Claim 4
Dependent Claim
48 words
The method of claim 1, wherein the lower end of the tube is secured within the aortic bifurcation by connecting the lower end of the tube to an expandable and deformable tubular member, which is forced radially outwardly into contact with the interior surface of the aortic bifurcation.
Claim 5
Dependent Claim
37 words
The method of claim 3, wherein the expandable and deformable tubular member is forced radially outwardly by expanding a second expandable, inflatable portion of the first catheter to expand and deform the expandable and deformable tubular member.
Claim 6
Dependent Claim
48 words
The method of claim 1, wherein the lower end of the tube in secured within the aortic bifurcation by disposing an expandable and deformable tubular member within the lower end of the tube, which is forced radially outwardly into contact with the interior surface of the aortic bifurcation.
Claim 7
Dependent Claim
36 words
The method of claim 5, wherein the expandable and deformable tubular member is forced radially outwardly by expanding an expandable, inflatable portion of a second catheter to expand and deform the expandable and deformable tubular member.
Claim 8
Dependent Claim
27 words
The method of claim 1, including the step of crimping the tube to form an undulating, longitudinal cross-sectional configuration to minimize kinking or twisting of the tube.
Claim 9
Independent Claim
163 words
A method for repairing an abdominal aortic aneurysm in an aorta having two iliac arteries associated therewith at an aortic bifurcation having an interior surface, comprising the steps of: (a) connecting an upper end of a tube to an expandable, tubular member; (b) disposing the tube and tubular member upon a catheter having a first expandable, inflatable portion with the tubular member disposed upon the first expandable, inflatable portion; (c) intraluminally delivering the tube, tubular member and catheter to the aorta and disposing at least a portion of the tube within the abdominal aortic aneurysm; (d) expanding the first expandable, inflatable portion of the catheter to expand the tubular member to force the tubular member radially outwardly into contact with the aorta to secure the tubular member and at least a portion of the tube within the aorta; and (e) sealing a lower end of the tube within the aortic bifurcation whereby the tube provides a fluid passageway through the abdominal aortic aneurysm.
Claim 10
Independent Claim
163 words
A method for repairing an abdominal aortic aneurysm in an aorta having two iliac arteries associated therewith at an aortic bifurcation having an interior surface, comprising the steps of: (a) connecting an upper end of a tube to an expandable, tubular member; (b) disposing the tube and tubular member upon a catheter having a first expandable, inflatable portion with the tubular member disposed upon the first expandable, inflatable portion; (c) intraluminally delivering the tube, tubular member and catheter to the aorta and disposing at least a portion of the tube within the abdominal aortic aneurysm; (d) expanding the first expandable, inflatable portion of the catheter to expand the tubular member to force the tubular member radially outwardly into contact with the aorta to secure the tubular member and at least a portion of the tube within the aorta; and (e) sealing a lower end of the tube within the aortic bifurcation whereby the tube provides a fluid passageway through the abdominal aortic aneurysm.
Claim 11
Dependent Claim
20 words
The method of claim 8, including the step of not piercing the aorta by the expansion of the tubular member.
Claim 12
Dependent Claim
59 words
The method of claim 8, wherein the second end of the tube is sealed within the aortic bifurcation by associating at least one wire with a lower end of the tube, and forcing the at least one wire and lower end of the tube outwardly to conform to, and sealingly engage against, the interior surface of the aortic bifurcation.
Claim 13
Dependent Claim
22 words
The method of claim 10, including the step of weaving the at least one wire into the lower end of the tube.
Claim 14
Dependent Claim
20 words
The method of claim 11, including the step of weaving the at least one wire in a generally zigzag pattern.
Claim 15
Dependent Claim
39 words
The method of claim 11, including the step of weaving the at least one wire into the lower end of the tube with portions of the at least one wire extending outwardly of the lower end of the tube.
Claim 16
Dependent Claim
38 words
The method claim 11, including the step of weaving the at least one wire into the lower end of the tube with portions of the at least one wire extending inwardly of the lower end of the tube.
Claim 17
Dependent Claim
17 words
The method of claim 10, including the step of utilizing at least one wire made of gold.
Claim 18
Dependent Claim
17 words
The method of claim 10, including the step of utilizing at least one wire made of tantalum.
Claim 19
Dependent Claim
27 words
The method of claim 10, including the step of crimping the tube to form an undulating, longitudinal cross-sectional configuration to minimize kinking or twisting of the tube.
