Abstract

The invention is a system, apparatus, and method for treating or repairing, an aneurysm in a large vessel, such as a thoracic aneurysm. The systems, devices, and methods of the present invention include a first prosthesis for anchoring a proximal end of the system in the blood vessel, a second prosthesis for anchoring a distal end of the system, and at least one third second prosthesis for bypassing the aneurysm, the first prosthesis optionally further comprising a seat or the like adapted and configured to receive the third prosthesis.

Claims (26)

1. A system for repairing an aneurysm in a large blood vessel comprising a first prosthesis, a second prosthesis, and at least one third prosthesis, said first prosthesis comprising a stent and a gasket for sealing the system; said second prosthesis comprising a stent and a gasket material for anchoring a distal portion of the system; said third prosthesis comprising a stent and a graft material for establishing a fluid flow path therethrough;
wherein the first prosthesis, the second prosthesis, and the third prosthesis form at least one fluid flow path through the aneurysm.
2. The system of claim 1 wherein the first prosthesis is matingly engaged with the second prosthesis.
3. The system of claim 2 further comprising a first prosthesis having a stent comprising at least one distally extending leg that matingly engages a proximal portion of the second prosthesis.
4. The system of claim 1 wherein the first prosthesis and the second prosthesis form a unitary structure.
5. The system of claim 1 wherein the first prosthesis further comprises at least one seat for receiving a proximal portion of the third prosthesis.
6. The system of claim 1 wherein the second prosthesis further comprises at feast one seat for receiving a distal portion of the third prosthesis.
7. The system of claim 5 wherein said seat is a gasket having a hole configured to sealingly engage the third prosthesis.
8. The system of claim 6 wherein said seat is a gasket having a hole configured to sealingly engage the third prosthesis.
9. The system of claim 7 wherein the gasket comprises a compressible foam.
10. The system of claim 8 wherein the gasket comprises a compressible foam.
11. The system of claim 9 wherein the gasket comprises at least one first thread defining a first region for receiving the third prosthesis.
12. The system of claim 10 wherein the gasket comprises at least one first thread defining a first region for receiving the third prosthesis.
13. The system of claim 1 wherein the first prosthesis comprises at least one receptacle, said receptacle comprising at least one portion configured to receive a third prosthesis.
14. The system of claim 1 wherein the second prosthesis comprises at least one receptacle, said receptacle comprising at least one portion configured to receive a third prosthesis.
15. The system of claim 13 wherein the first prosthesis is moveable between a closed condition and an expanded condition, and said receptacle sealingly engages the third prosthesis when the first prosthesis is in the expanded condition.
16. The system of claim 14 wherein the second prosthesis is moveable between a closed condition and an expanded condition, and said receptacle sealingly engages the third prosthesis when the second prosthesis is in the expanded condition.
17.

and delivering a conduit having a proximal end and a distal end, and positioning the proximal end of the conduit in the proximal end of the prosthesis, and positioning the distal end of the conduit in the distal end of the prosthesis.
20. The method of claim 19 wherein positioning the proximal end of the conduit in the proximal end of the prosthesis includes engaging the proximal end of the conduit in a receptacle configured to receive the conduit.
21. The method of claim 19 wherein positioning the distal end of the conduit in the distal end of the prosthesis includes engaging the distal end of the conduit in a receptacle configured to receive the conduit.
22. The method of claim 19 wherein delivering a prosthesis includes delivering the prosthesis in an unexpanded condition.
23. The method of claim 19 wherein positioning the proximal end and positioning the distal end further include expanding the prosthesis.
24. The method of claim 23 wherein expanding the prosthesis further comprises forming a fluid tight seal around the proximal end of the conduit.
25. A system for bypassing a thoracic aneurysm comprising a first prosthesis and a second prosthesis, each of said first and second prostheses being configured to engage a portion of a thoracic artery, wherein said first prosthesis is adapted to engage a portion of a thoracic artery upstream of said aneurysm, wherein said second prosthesis is adapted to engage a portion of a thoracic artery downstream of said aneurysm; and at least one third prosthesis configured to provide a fluid flow path that bypasses said aneurysm.
26. A system for bypassing a thoracic aneurysm comprising a first prosthesis and a second prosthesis, wherein said first prosthesis comprises a matrix of interconnected struts and a gasket material covering at least a portion of said matrix; and wherein said second prosthesis comprises a matrix of interconnected struts and a gasket material covering at least a portion of said matrix; wherein said first prosthesis is adapted to engage a portion of an artery upstream of said aneurysm, wherein a distally extending portion of the matrix of the first prosthesis communicates with the matrix of the second prosthesis; and at least one third prosthesis configured to provide a fluid flow path that bypasses said aneurysm.
