First Claim
Patent Images
1. A bilateral intra-aortic bypass graft for intraluminal delivery to repair an abdominal aortic aneurysm in an aorta having a diameter and two iliac arteries associated therewith, by forming a bilateral passageway through the abdominal aortic aneurysm, comprising:
- a first tube having a diameter, first and second ends and a wall surface disposed between the two ends, at least a portion of the first tube adapted to be disposed within the abdominal aortic aneurysm;
a second tube having a diameter, first and second ends and a wall surface disposed between the two ends, at least a portion of the second tube adapted to be disposed within the abdominal aortic aneurysm; and
means for securing the first ends of the first and second tubes in an abutting relationship in the aorta, the securing means including first and second tubular members, each tubular member having first and second ends, the first tube being connected to the first tubular member and the second tube being connected to the second tubular member, the tubular members having a first diameter which permits intraluminal delivery of the tubular members and tubes into the aorta and the tubular members each having a second, expanded and deformed diameter, with at least a portion of the first and second tubular members in an abutting relationship, upon the application from the interior of the tubular members of a radially, outwardly extending force, to expand and deform the tubular members to secure the first ends of the tubular members to the aorta in an abutting relationship and to form a bilateral passageway within the abdominal aortic aneurysm.

Abstract
A bilateral intra-aortic bypass graft and method and apparatus for repairing an abdominal aortic aneurysm includes two tubular grafts which are intraluminally delivered to the aorta and secured to the aorta by the expansion and deformation of two expandable and deformable tubular members.

23. An apparatus for repairing an abdominal aortic aneurysm in an aorta having a diameter and two iliac arteries associated therewith, by forming a bilateral passageway through the abdominal aortic aneurysm, comprising:
-
(a) first and second tubes, each tube having a diameter, first and second ends and a wall surface disposed between the two ends;
(b) first and second expandable and deformable tubular members, each expandable and deformable tubular member, having first and second ends and a smooth outer wall surface disposed between the first and second ends, the first end of a tube being secured to a second and end of a tubular member, the expansion and deformation of the tubular members being controllable; and
(c) two catheters, each catheter having an expandable, inflatable portion associated therewith, the tubular members being releasably mounted upon the inflatable portions of each catheter, whereby upon inflation of the expandable, inflatable portion of each catheter, the tubular members are forced radially outwardly into contact in an abutting relationship with the aorta and each other to remain secured thereto, whereby the tubes, secured to the tubular members, provide a bilateral passageway through the abdominal aortic aneurysm. - View Dependent Claims (24, 25, 26, 27)

28. A bilateral bypass graft for a body passageway, having a diameter, for intraluminal delivery to repair the body passageway by forming a bilateral passageway through the body passageway, comprising:
-
a first tube having a diameter, first and second ends and a wall surface disposed between the two ends, at least a portion of the first tube adapted to be disposed within the body passageway;
a second tube having a diameter, first and second ends and a wall surface disposed between the two ends, at least a portion of the second tube adapted to be disposed within the body passageway; and
means for securing the first ends of the first and second tubes in an abutting relationship in the body passageway, the securing means including first and second tubular members, each tubular member having first and second ends, the first tube being connected to the first tubular member and the second tube being connected to the second tubular member, the tubular members having a first diameter which permits intraluminal delivery of the tubular members and tubes into the body passageway and the tubular members each having a second, expanded and deformed diameter, with at least a portion of the first and second tubular members in an abutting relationship, upon the application from the interior of the tubular members of a radially, outwardly extending force, to expand and deform the tubular members to secure the first ends of the tubular members to the body passageway in an abutting relationship and to form a bilateral passageway within the body passageway. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49)
