Balloon device for use in repairing an abdominal aortic aneurysm
First Claim
Patent Images
1. A balloon device for use in repairing an abdominal aortic aneurysm in an aorta having two iliac arteries associated therewith at an aortic bifurcation, comprising:
- a catheter having a longitudinal axis and at least three internal passageways;
first and second inflatable balloons disposed upon the catheter and separated by a predetermined distance, each balloon connected to at least one of the internal passageways, the second balloon having first and second ends and a longitudinal axis which is substantially parallel to the longitudinal axis of the catheter, the first end of the second balloon being disposed closer to the first balloon than the second end of the second balloon;
the first and second balloons having a generally cylindrical cross-sectional configuration upon being inflated defined by an outer wall surface;
the second end of the second balloon including an end wall surface which is disposed substantially perpendicular to the longitudinal axis of a first portion of the catheter disposed within the second balloon and substantially perpendicular to the outer wall surface of the second balloon, whereby the second balloon may be readily disposed within the aortic bifurcation; and
a second portion of the catheter located adjacent the second end, and outside, of the second balloon is disposed at an angle of approximately thirty degrees with respect to the longitudinal axis of the second balloon, whereby the second portion of the catheter may be readily disposed in an iliac artery adjacent the aortic bifurcation.

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.

6. A balloon device for use in repairing an abdominal aortic aneurysm in an aorta having two iliac arteries associated therewith at an aortic bifurcation, comprising:
-
a catheter having a longitudinal axis and at least three internal passageways; first and second inflatable balloons disposed upon the catheter and separated by a predetermined distance, each balloon connected to at least one of the internal passageways, the second balloon having first and second ends and a longitudinal axis which is substantially parallel to the longitudinal axis of the catheter, the first end of the second balloon being disposed closer to the first balloon than the second end of the second balloon; the first and second balloons having a generally cylindrical cross-sectional configuration upon being inflated defined by an outer wall surface; and the second end of the second balloon including an end wall surface which is disposed substantially perpendicular to the longitudinal axis of a first portion of the catheter disposed within the second balloon and substantially perpendicular to the outer wall surface of the second balloon, whereby the second balloon may be readily disposed within the aortic bifurcation; and a second portion of the catheter located adjacent the second end, and outside, of the second balloon is more flexible than the first portion of the catheter to permit the second portion of the catheter to be readily disposed at an angle of approximately thirty degrees with respect to the longitudinal axis of the second balloon, whereby the second portion of the catheter may be readily disposed in an iliac artery adjacent the aortic bifurcation. - View Dependent Claims (7, 8)
