Abstract

This invention is an endoluminal device including a stent; a tubular graft supported by the stent, wherein the graft comprises a proximal opening and a distal opening; and a variable diameter ring adjacent one of said openings, wherein the variable diameter ring comprises a coiled length of wire having two ends and forming at least one winding around the tubular graft. This invention also relates to the methods of treating an aneurysm and making the endoluminal device.

Claims

1. An endoluminal device, comprising:

a stent;

a tubular graft supported by the stent, wherein the graft comprises at least a proximal opening and a distal opening; and

a variable diameter ring at or adjacent one of said openings, wherein the variable diameter ring comprises a coiled length of wire having two ends and forming substantially at least one winding around the tubular graft.

2. The endoluminal device of claim 1, wherein the ring is a nitinol ring.

3. The endoluminal device of claim 1, wherein the ring is a self-expanding ring or a balloon-expandable ring.

4. The endoluminal device of claim 1, wherein the ring has a plurality of windings.

5. The endoluminal device of claim 4, wherein the ring has at least 5 windings.

6. The endoluminal device of claim 1, wherein the wire has a diameter in the range from about 0.005 cm to about 0.008 cm (about 0.002 inches to about 0.003 inches).

7. The endoluminal device of claim 1, wherein the tubular graft is branched and comprises a second distal opening.

8. The endoluminal device of claim 1, further comprising at least one additional variable diameter ring at or adjacent at least one other of said openings.

9. The endoluminal device of claim 1, wherein the stent is a self-expanding stent or a balloon-expandable stent.

10. The endoluminal device of claim 1, wherein the stent is a nitinol stent.

11. The endoluminal device of claim 1, comprising a plurality of stents.

12. The endoluminal device of claim 1, wherein the tubular graft comprises an extracellular matrix material.

13. The endoluminal device of claim 12, wherein the extracellular matrix material is a small intestine submucosa material.

14. The endoluminal device of claim 1, further comprising a lubricant.

15. The endoluminal device of claim 1, further comprising a hydrophillic coating.

16. A method for treating an aneurysm, the method comprising delivering the endoluminal device of claim 1 to a location near the aneurysm.

17. The method of claim 16, wherein the aneurysm is an abdominal aortic aneurysm.

18. A method of making an endoluminal device, comprising

providing a stent graft wherein the stent graft comprises at least a proximal opening and a distal opening;

and

attaching a variable diameter at or adjacent one of said openings, wherein the variable diameter ring comprises a coiled length of wire having two ends and forming substantially at least one winding around the stent graft.

19. The method of claim 18, further including attaching at least one additional variable diameter ring at or adjacent at least one other of said openings.
