Abstract

The present invention is a system, apparatus, and method for treating, repairing, and/or replacing an aneurysm, preferably an aortic aneurysm, and 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 comprising a first prosthesis and at least one second prosthesis communicating with the first prosthesis, and at least one third prosthesis communicating with the first prosthesis;

said first prosthesis comprising a proximal end configured to engage a section of artery upstream of a junction between a first artery and a second artery, said second prosthesis being configured to bypass the aneurysm, and said third prosthesis being configured to provide a fluid flow channel from the first artery into the second artery.

2. The system of claim 1 wherein the first prosthesis comprises a stent and a gasket material communicating with the stent.

3. The system of claim 2 wherein said stent and gasket material seal the system in an artery.

4. The system of claim 1 wherein said first prosthesis comprises a proximal end comprising a first matrix comprising proximally extending struts.

5. The system of claim 4 wherein the struts form at least one geometric shape.

6. The system of claim 4 wherein said first matrix is configured to receive at least one second prosthesis.

7. The system of claim 6 wherein said first matrix is configured to receive two second prostheses.

8. The system of claim 4 wherein the first matrix is configured to anchor the prosthesis in an artery.

9. The system of claim 1 wherein the second prosthesis comprises a stent and a graft material communicating with the stent.

10. The system of claim 9 wherein said stent and graft material defines a fluid flow path through the prosthesis.

11. The system of claim 10 wherein the fluid flow path is a channel that bypasses the aneurysm.

12. The system of claim 1 wherein the third prosthesis comprises a stent and a graft material communicating with the stent.

13. The system of claim 12 wherein said stent and graft material defines a fluid flow path through the prosthesis.

14. The system of claim 11 wherein the fluid flow path is a channel from a proximal end of the first prosthesis into the second artery.

17. The method of claim 13 further comprising anchoring a distal end of the second prosthesis in an artery downstream of the aneurysm.

18. The method of claim 13 further comprising anchoring a distal end of the third prosthesis in the second artery.

15. A system for bypassing an aneurysm comprising a first prosthesis, at least two second prostheses communicating with the first prosthesis, and at least two third prosthesis communicating with the first prosthesis;

said first prosthesis comprising a proximal end configured to engage a section of artery upstream of a junction between a first artery and a second artery, said second prosthesis being configured to bypass the aneurysm and anchor in an artery downstream of the aneurysm, and said third prosthesis being configured to provide a fluid flow channel from the first artery into the second artery.

16. A method for bypassing an aneurysm downstream of a junction between a first artery and a second artery comprising positioning a first prosthesis in a first section of the first artery;

engaging at least one second prosthesis with the first prosthesis, said second prosthesis forming a fluid flow path that bypasses the aneurysm; and

engaging at least one third prosthesis with the first prosthesis, said third prosthesis forming a fluid flow path into the second artery.

19. A method for bypassing an aneurysm comprising anchoring a first portion of a first prosthesis upstream of a branch artery, seating a second portion of the first prosthesis downstream of the branch artery, and engaging a second prosthesis to the second portion of the first prosthesis.
