First Claim
Patent Images
1. A balloon device for implanting an intraluminal aortic or aortodiiliac prosthesis for repairing aneurysms, comprising:
- a catheter having a longitudinal axis and at least three internal passages;
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 passages 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; and
the second end of the second balloon having an outlet for the catheter, the outlet being displaced from the longitudinal axis of the second balloon at an angle of approximately thirty degrees.

5. A method for implanting an intraluminal aortic or aortodiiliac prosthesis for repairing aneurysms, the prosthesis having first and second ends with a tubular liner disposed therebetween, and first and second stents attached to the liner at each of its ends comprising the steps of:
-
disposing upon a catheter, having a longitudinal axis, first and second inflatable balloons separated by a predetermined distance, each balloon having first and second ends, the first end of the second balloon being disposed closer to the first balloon than the second end of the second balloon, the second balloon having a longitudinal axis which is substantially parallel to the longitudinal axis of the catheter; disposing the catheter to enter the second end of the second balloon at an angle of approximately thirty degrees with respect to the longitudinal axis of the second balloon; mounting the prosthesis upon the catheter; disposing the first and second stents respectively upon the first and second balloons; introducing the catheter, having the prosthesis disposed thereon, into the aneurysm by catheterization; inflating the first and second balloons to implant the prosthesis within the aneurysm; and deflating the first and second balloons and removing the catheter from the aneurysm. - View Dependent Claims (6, 7, 8, 9)

10. A balloon device for implanting an intraluminal aortic or aortodiiliac prosthesis for repairing aneurysms, comprising:
-
a catheter having a longitudinal axis and at least three internal passages; 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 passages, wherein the second balloon has a substantially tubular cross-sectional configuration with a radial dimension R, 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; and the second end of the second balloon having an outlet for the catheter, the outlet being displaced from the longitudinal axis of the second balloon at an approximate distance of 1/2R. - View Dependent Claims (11, 12)

13. A method for implanting an intraluminal aortic or aortodiiliac prosthesis for repairing aneurysms, the prosthesis having first and second ends with a tubular liner disposed therebetween, and first and second stents attached to the liner at each of its ends, comprising the steps of:
-
disposing upon a catheter having a longitudinal axis, first and second inflatable balloons separated by a predetermined distance, each balloon having first and second ends, the first end of the second balloon being disposed closer to the first balloon than the second end of the second balloon, the second balloon having a substantially tubular cross-sectional configuration about the longitudinal axis of the catheter; disposing the catheter to enter the second end of the second balloon at a distance from the longitudinal axis of the second balloon of approximately 1/2 of the radial dimension of the second balloon; mounting the prosthesis upon the catheter; disposing the first and second stents respectively upon the first and second balloons; introducing the catheter, having the prosthesis disposed thereon, into the aneurysm by catheterization; inflating the first and second balloons to implant the prosthesis within the aneurysm; and deflating the first and second balloons and removing the catheter from the aneurysm. - View Dependent Claims (14, 15)
