Abstract

The present invention is a system, apparatus, and method for treating, repairing, and/or replacing an aneurysm, preferably an aortic aneurysm, the most preferably, an abdominal aortic aneurysm. The systems, devices, and methods of the present invention include a first prosthesis or stent gasket, and at least one second prosthesis for bypassing the aneurysm, and at least one third prosthesis for establishing a fluid flow channel from the abdominal aorta into another artery, such as a renal artery.

Claims

1. A system for bypassing an aneurysm in an artery comprising:

a first prosthesis having a proximal end, a distal end and a substantially tubular body;

a gasket covering at least a portion of the proximal end and a portion of the substantially tubular body, said gasket including a plurality of apertures in a portion of the gasket covering the proximal end of the first prosthesis such that the apertures are in line with the substantially tubular body;

at least one second prosthesis matingly engaged with the proximal end of the first prosthesis through one of the plurality of apertures, said second prosthesis being configured to provide a fluid flow path that extends through the aneurysm; and

a pair of third prostheses matingly engaged with the proximal end of said first prosthesis through respective ones of the plurality of apertures, each one of said pair of third prostheses being configured to provide a fluid flow path that extends into a cross artery upstream of the aneurysm.

2. The system of claim 1 wherein said pair of third prostheses are configured to be anchored in respective cross arteries.

3. The system of claim 1 wherein each one of the pair of third prostheses is configured to provide a fluid flow path that extends from the proximal end of the first prosthesis into respective renal arteries.

4. The system of claim 1 wherein said first prosthesis is configured to be anchored in the artery upstream from the aneurysm and upstream from the cross arteries.

5. The system of claim 4 wherein the first prosthesis is configured to be anchored in the abdominal aorta upstream from the aneurysm and upstream from the renal arteries.

6. The system of claim 1 wherein said second and third prostheses are expandable.

7. The system of claim 6 wherein a diameter of the one of the plurality of apertures engaged with the at least one second prosthesis is slightly smaller than an expanded diameter of the at least one second prosthesis.

8. The system of claim 6 wherein a diameter of the respective ones of the plurality of apertures engaged with the pair of third prostheses is slightly smaller than an expanded diameter of each of the pair of third prostheses.
