Abstract

An endoluminal graft includes a tubular graft material having a closed sleeve integral with the tubular graft material. The closed sleeve extends a distance along the tubular graft material. A length of wire extends at least partially along the distance and is enclosed by the sleeve. The tubular graft material and the sleeve may comprise a single piece of graft material. The sleeve may be a closed circumferential sleeve and/or a closed longitudinal sleeve.

First claim

The invention claimed is:

1. An endoluminal graft comprising:
a tubular graft having a lumen;
a first closed sleeve separate from and adjacent to the lumen, the first closed sleeve positioned at a first end of the endoluminal graft and comprising an interior void extending along a circumference of the first end about a periphery of the lumen;
a second closed sleeve separate from and adjacent to the lumen, the second closed sleeve positioned at a second end of the endoluminal graft opposite the first end, the second closed sleeve comprising an interior void extending along a circumference of the second end about a periphery of the lumen;
a first wire having a first length formed into a generally closed shape and a second length formed into a spine, wherein the first length of the first wire formed into the generally closed shape is at least partially enclosed within the first closed sleeve, and the second length of the first wire formed into the spine extends toward the second end of the endoluminal graft; and,
a second wire having a first length formed into a generally closed shape and a second length formed into a spine, wherein the first length of the second wire formed into the generally closed shape is at least partially enclosed within the second closed sleeve, and the second length of the second wire formed into the spine extends toward the first end of the endoluminal graft;
wherein the tubular graft, the first closed sleeve, and the second closed sleeve comprise a single piece of graft material;
wherein the second length of the first wire comprises a first loop formed at the second end of the endoluminal graft, and the second length of the second wire comprises a second loop formed at the first end of the endoluminal graft; and,
wherein the first loop of the first wire is anchored to the second wire.

2. The endoluminal graft of claim 1 , wherein the first closed sleeve and the second closed sleeve are integral with the tubular graft and characterized by the absence of any circumferential seam.

3. The endoluminal graft of claim 1 , wherein the single piece of graft material is a textile.

4. The endoluminal graft of claim 1 , wherein the first loop of the first wire is anchored to the second wire via a suture.

5. The endoluminal graft of claim 1 , wherein the second loop of the second wire is anchored to the first wire.

6. The endoluminal graft of claim 1 , wherein the first wire is anchored to the second wire at the locations of the first loop and the second loop.

7. The endoluminal graft of claim 1 , wherein the second length of the first wire and the second length of the second wire are positioned opposite one another along a length of the endoluminal graft.

8. The endoluminal graft of claim 1 , wherein the second length of the first wire formed into the spine is at least partially enclosed within a closed longitudinal sleeve adjacent to the lumen and extending toward the second end of the endoluminal graft.

9. The endoluminal graft of claim 1 , wherein the second length of the second wire formed into the spine is at least partially enclosed within a closed longitudinal sleeve adjacent to the lumen and extending toward the first end of the endoluminal graft.

10. An endoluminal graft comprising:
a tubular graft having a lumen;
a first closed sleeve separate from and adjacent to the lumen, the first closed sleeve positioned at a first end of the endoluminal graft and comprising an interior void extending along a circumference of the first end about a periphery of the lumen;
a second closed sleeve separate from and adjacent to the lumen, the second closed sleeve positioned at a second end of the endoluminal graft opposite the first end, the second closed sleeve comprising an interior void extending along a circumference of the second end about a periphery of the lumen;
a first wire having a first length formed into a generally closed shape and a second length formed into a spine and a first loop, wherein the first length of the first wire formed into the generally closed shape is at least partially enclosed within the first closed sleeve, and the second length of the first wire formed into the spine extends to the second end of the endoluminal graft, with the first loop being located at the second end; and,
a second wire having a first length formed into a generally closed shape and a second length formed into a spine and a second loop, wherein the first length of the second wire formed into the generally closed shape is at least partially enclosed within the second closed sleeve, and the second length of the second wire formed into the spine extends toward the first end of the endoluminal graft, with the second loop being located at the first end;
wherein the first wire is anchored to the second wire at the location of the first loop and the second loop; and,
wherein the tubular graft, the first closed sleeve, and the second closed sleeve comprise a single piece of graft material.

11. The endoluminal graft of claim 10 , wherein the second length of the first wire and the second length of the second wire are positioned opposite one another along a length of the endoluminal graft.

12. The endoluminal graft of claim 10 , wherein the single piece of graft material is a textile.

13. An endoluminal graft comprising:
a tubular graft having a lumen;
a first closed sleeve separate from and adjacent to the lumen, the first closed sleeve positioned at a first end of the endoluminal graft and comprising an interior void extending along a circumference of the first end about a periphery of the lumen;
a second closed sleeve separate from and adjacent to the lumen, the second closed sleeve positioned at a second end of the endoluminal graft opposite the first end, the second closed sleeve comprising an interior void extending along a circumference of the second end about a periphery of the lumen;
a first wire having a first length formed into a generally closed shape and a second length formed into a spine, wherein the first length of the first wire formed into the generally closed shape is at least partially enclosed within the first closed sleeve, and the second length of the first wire formed into the spine extends toward the second end of the endoluminal graft; and,
a second wire having a first length formed into a generally closed shape and a second length formed into a spine, wherein the first length of the second wire formed into the generally closed shape is at least partially enclosed within the second closed sleeve, and the second length of the second wire formed into the spine extends toward the first end of the endoluminal graft;
wherein the tubular graft, the first closed sleeve, and the second closed sleeve comprise a single piece of graft material; and,
wherein the second length of the first wire formed into the spine is at least partially enclosed within a closed longitudinal sleeve adjacent to the lumen and extending toward the second end of the endoluminal graft.

14. The endoluminal graft of claim 13 , wherein the first closed sleeve and the second closed sleeve are integral with the tubular graft and characterized by the absence of any circumferential seam.

15. The endoluminal graft of claim 13 , wherein the single piece of graft material is a textile.

16. The endoluminal graft of claim 13 , wherein the second length of the first wire comprises a first loop formed at the second end of the endoluminal graft, and the second length of the second wire comprises a second loop formed at the first end of the endoluminal graft.

17. The endoluminal graft of c
