Method for repairing an abdominal aortic aneurysm
First Claim
Patent Images
1. A method for repairing an abdominal aortic aneurysm--in an aorta having two iliac arteries associated therewith, comprising the steps of:
- (a) connecting a tube to a first expandable and deformable, tubular member having a smooth outer wall surface, by disposing a first portion of the tubular member within the tube and disposing a second portion of the tubular member outside the tube, the tubular member having a first diameter which permits intraluminal delivery of the tubular member into the aorta;
(b) disposing the tube and tubular member upon a catheter having an expandable, inflatable portion with the tubular member disposed upon the 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; and
(d) expanding the expandable, inflatable portion of the catheter to expand and deform the tubular member to a second, expanded diameter, which diameter is variable and dependent upon the force applied to the tubular member, and to force the tubular member radially outwardly to force the second portion of the tubular member into contact with the aorta to secure the tubular member and at least a portion of the tube within the aorta, without perforating the aorta by the expansion and deformation of the tubular member, whereby the tube provides a fluid passageway through the abdominal aortic aneurysm.

Abstract
An aortic graft, and method and apparatus for repairing an abdominal aortic aneurysm includes a tubular graft which is intraluminally delivered through the aorta and secured to the aorta by the expansion and deformation of a thin-walled tubular member.

14. A method for repairing an abdominal aortic aneurysm in an aorta having two iliac arteries associated therewith, comprising the steps of:
-
(a) connecting a tube to a first expandable and deformable, tubular member having a length and a smooth outer wall surface, by overlapping and covering a first portion of the length of the tubular member with a second portion of the length of the tubular member extending outwardly from the tube; (b) disposing the tube and tubular member upon a catheter having an expandable, inflatable portion with the tubular member disposed upon the 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; and (d) expanding the expandable, inflatable portion of the catheter to expand and deform the tubular member to force the second portion of the length of 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, without perforating the aorta by the expansion and deformation of the tubular member, whereby the tube provides a fluid passageway through the abdominal aortic aneurysm. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23)
