Abstract

Claims (32)

1. A system, comprising:

a) a graft ( 361 ), the graft having an interior and an outer surface, and includes flap portions ( 369 ) formed in a side of the graft ( 361 ) defining a pilot hole ( 365 ) and cuts ( 367 ); and

b) a ring-shaped patch ( 340 ) that defines an internal edge and is coupled to an area of the graft surrounding the flap portions;

c) wherein the graft is an endograft; and

d) an outer patch that is coupled to the flap portions and to the ring-shaped patch, thereby further securing the flap portions in place.

2. The system of claim 1 , wherein the graft includes eight flap portions, thereby defining eight cuts.

3. The system of claim 1 , wherein the edges of the cuts are aligned with the internal edge of the ring-shaped patch.

4. The system of claim 1 , wherein the ring-shaped patch is formed of a radiopaque material.

5. The system of claim 1 , wherein the ring-shaped patch is coupled to the graft by an adhesive, sutures or welding.

6. The system of claim 1 , wherein the flap portions are pulled proximally away from the interior of the graft and folded toward the outer surface of the graft.

7. The system of claim 6 , wherein the flap portions are attached to the ring-shaped patch.

8. The system of claim 7 , further including a plurality of fasteners, whereby the flap portions are secured to the ring-shaped patch.

9. The system of claim 6 , further including fasteners, whereby the flap portions are attached to the graft.

10. The system of claim 9 , wherein the fasteners include at least one of sutures, staples, rivets or microrivets.

11. The system of claim 1 , further including an adhesive on a side of the outer patch that is in contact with the flap portions and the ring-shaped patch, and that secures the ring-shaped patch to the outer patch.

12. The system of claim 1 , further including fasteners that fasten the outer patch to the flap portions and to the ring-shaped patch.

13. The system of claim 12 , wherein the fasteners include at least one of sutures, staples, and rivets.

14. The system of claim 1 , further including fasteners, wherein the outer patch is fastened to at least one of flap portions, the patch, and the graft.

15. The system of claim 14 , wherein the fasteners include at least one of sutures, staples, and rivets.

16. The system of claim 1 , further including fasteners, wherein the outer patch is fastened to the flap portions, the ring-shaped patch, and the graft.

17. The system of claim 16 , wherein the fasteners include at least one of sutures, staples, and rivets.

18. A system, comprising:

a) a graft ( 361 ), the graft having an interior and an outer surface, and includes flap portions ( 369 ) defining a pilot hole ( 365 ) and cuts ( 367 ); and

b) a ring-shaped patch ( 340 ) that defines an internal edge and is coupled to an area of the graft surrounding the flap portions; wherein flap portions are attached to the ring-shaped patch and the flap portions lie flat against a surface of a ring-shaped patch, thereby forming a fenestration.

19. The system of claim 18 , wherein the ring-shaped patch is coated in pressure-sensitive adhesive, such that the flap portions are secured to the ring-shaped patch.

20. The system of claim 18 , wherein the fasteners include at least one of sutures, staples, rivets or micro-rivets.

21. The system of claim 18 , wherein the fasteners include a material with radiopaque properties.

22. The system of claim 18 , wherein the flap portions are welded to the ring-shaped patch.

23. A system, comprising:

a) a graft ( 361 ), the graft having an outer surface, and includes flap portions ( 369 ) defining a pilot hole ( 365 ) and cuts ( 367 ), wherein the flap portions are folded against the outer surface of the graft; and

b) an outer patch ( 342 ) that is coupled to the graft such that the flap portions are sandwiched between the outer surface of the graft and the outer patch.

24. The system of claim 23 , wherein the graft is an endograft.
