Abstract

An aortic stent graft and a method of deploying the aortic stent graft. The method comprises providing a tapered tubular graft having a distal end and a proximal end, providing at least one stent attached to the graft at a site adjacent the distal end of the graft, loading the graft into an introducer, inserting the introducer through an incision in the aorta, deploying the graft inside the aorta; and suturing the proximal end of the graft in place.

Claims

1. A method of deploying an aortic stent graft, comprising:

providing a tapered tubular graft having a distal end and a proximal end;

providing at least one stent attached to the graft at a site adjacent the distal end of the graft;

loading the graft into an introducer;

inserting the introducer through an incision in the aorta;

deploying the graft inside the aorta; and

suturing the proximal end of the graft in place.

2. The method of claim 1, further comprising providing barbs extending proximally from the at least one stent;

and

allowing the barbs to engage the aorta when the graft is deployed inside the aorta.

3. The method of claim 1, wherein suturing the proximal end of the graft in place comprises suturing the proximal end of the graft to the aorta.

4. The method of claim 3, wherein suturing the proximal end of the graft in place comprises suturing the proximal end of the graft to a location adjacent a left subclavian artery.

5. The method of claim 1, wherein the stent graft further comprises a fenestration, the method further comprising resecting an island from the aorta and suturing the island to the fenestration.

6. The method of claim 1, wherein loading the graft into an introducer comprises connecting trigger wires to the distal end of the stent graft to constrain the distal end of the stent graft, and wherein deploying the graft inside the aorta further comprises releasing the trigger wire so that the distal end of the stent graft is free to expand.

7. The method of claim 4, wherein the proximal end defines at least one of a scallop and a fenestration for accommodating the left subclavian artery.

8. The method of claim 1, further comprising deploying a prosthetic module and forming an overlapping interconnection-with the stent graft.

9. The method of claim 1, wherein suturing the proximal end of the graft in place comprises suturing the proximal end of the graft to a preexisting aortic graft.

10. A method of deploying an aortic stent graft, comprising:

providing a tubular graft having a distal end and a proximal end;

providing at least one stent attached to the graft at a site adjacent the distal end of the graft, wherein barbs extend proximally from the at least one stent;

loading the graft into an introducer;

inserting the introducer through an incision in the aorta;

deploying the graft inside the aorta; and

suturing the proximal end of the graft in place.

11. The method of claim 10, wherein providing the graft includes providing the graft that is tapered.

12. A stent graft for implantation in an aorta, comprising:

a tapered tubular graft having a distal end and a proximal end; and

at least one stent attached to the graft in a site adjacent the distal end of the graft;

wherein the proximal end is adapted to being connected to the aorta without the assistance of a stent.

13. The stent graft of claim 12, wherein the tubular graft is tapered proximally.

14. The stent graft of claim 12, wherein the tubular graft is tapered distally.

15. The stent graft of claim 12, further comprising barbs extending from the at least one stent in a proximal direction.

16. The stent graft of claim 12, wherein the proximal end includes at least one of a fenestration and a scallop.

17. The stent graft of claim 12, further comprising a prosthetic module capable of forming an overlapping interconnection with the stent graft.

18. A stent graft for implantation in an aorta, comprising:

a tubular graft having a distal end and a proximal end;

at least one stent attached to the graft in a site adjacent the distal end of the graft; and

barbs extending from the at least one stent;

wherein the proximal end is adapted for stent-free connection to the aorta.

19. The stent graft of claim 18, wherein the tubular graft tapers towards the distal end.

20. The stent graft of claim 18, wherein the barbs extend from the stent in a proximal direction.

21. The stent graft of claim 18, further comprising a prosthetic module capable of forming an overlapping interconnection with the stent graft.
