Intraluminal graft
View Patent ↗An intraluminal graft includes a tubular graft body extending along a cylindrical axis, a plurality of wires spaced apart from each other and arranged to circumferentially reinforce said tubular graft body along a substantial portion of its length, and a body surface including an inner surface region and an outer surface region. The body surface defines a plurality of apertures extending from an exterior space, and a first portion of a first wire is in the interior space while a second portion of the first wire is in the exterior space.
1. A method of placing an intraluminal graft in an aortic artery, comprising:
positioning, in said aortic artery, an intraluminal graft;
wherein said intraluminal graft includes a wire apice connected to a first graft body;
wherein said wire apice extends from an aortic artery first region of said aortic artery, said aortic artery first region being between a femoral artery and a renal artery, to an aortic artery second region, said aortic artery second region being on an opposite side of said renal artery from said femoral artery, wherein said renal artery has an opening where said renal artery joins said aortic artery, and such that said wire apice extends across said opening of said renal artery.
2. The method of claim 1 wherein said first graft body does not occlude said renal artery.
3. The method of claim 1 wherein said first graft body resides in said aortic artery below said renal artery.
4. The method of claim 3 wherein said first graft body resides between said renal artery and said femoral artery.
5. The method of claim 1 wherein said positioning places graft body material of said intraluminal graft facing an aneurysm.
6. The method of claim 1 wherein said positioning places graft body material of said intraluminal graft facing an occlusion.
7. The method of claim 1 wherein said first graft body has a tubular shape.
8. The method of claim 1 wherein said positioning comprises pressing said wire apice against an inner surface of said aortic artery using a balloon.
9. The method of claim 1 wherein said wire apice is part of a first wire, and said first wire has a shape that is generally closed sinusoidal.
10. The method of claim 1 wherein said wire apice is part of a first wire, and said first wire has a shape that is generally closed zig-zag.
11. The method of claim 1 wherein said wire apice is part of a first wire, and further comprising at least a second wire not at an end of said intraluminal graft.
12. The method of claim 11 wherein said first wire forms a closed loop and said second wire forms a closed loop.
13. The method of claim 12 wherein said first wire and said second wire are not connected by wire to one another.
14. The method of claim 1 wherein said wire apice is part of a first wire, and further comprising at least a second wire not at an end of said first graft body and a third wire not at an end of said first graft body.
15. The method of claim 14 wherein said first wire, said second wire, and said third wire are not connected by wire to one another.
16. The method of claim 1 wherein said wire apice is part of a first wire, and wherein said wire apice is one of a plurality of wire apices of said first wire, and wherein at least two of said plurality of wire apices extend beyond said first graft body.
17. The method of claim 1 further comprising securing said intraluminal graft in place in said aortic artery while said wire apice extends from said aortic artery first region to said aortic artery second region, wherein said securing comprises forcing said wire apice into contact with an inside surface of said aortic artery.
18. A method of placing a prosthesis in an aortic artery, said prosthesis having a first end and a second end, said prosthesis comprising a graft body and a wire structure, said wire structure including a plurality of wire apices that extend beyond said first end, said method comprising:
positioning said prosthesis such that said plurality of wire apices extend across an opening of a renal artery, such that said graft body does not occlude said renal artery, wherein said opening is where said renal artery joins said aortic artery.
19. The method of claim 18 further comprising expanding a balloon to press said wire apices against an inner surface of said aortic artery.
20. A method of placing a prosthesis in an aortic artery, said prosthesis having a first end and a second end, said prosthesis comprising a graft body and a wire structure, said wire structure including a plurality of wire apices that extend beyond said first end, said method comprising:
positioning said prosthesis such that said plurality of wire apices extend across an opening of a renal artery, such that said graft body does not reside in said renal artery, wherein said opening is where said renal artery joins said aortic artery.
21. The method of claim 20 further comprising expanding a balloon to press said plurality of wire apices against an inner surface of said aortic artery.
22. A method of placing a prosthesis in an aortic artery, said prosthesis having a first end and a second end, said prosthesis comprising a graft body and a wire structure, said wire structure including a plurality of wire apices that extend beyond said first end, said method comprising:
positioning said prosthesis such that said plurality of wire apices extend across an opening of a renal artery, such that said graft body does not face said renal artery, wherein said opening is where said renal artery joins said aortic artery.
23. The method of claim 22 further comprising expanding a balloon to press said plurality of wire apices against an inner surface of said aortic artery.
24. A method of placing a prosthesis in an aortic artery, said prosthesis having a first end and a second end, said prosthesis comprising a graft body and a wire structure, said wire structure including a plurality of wire apices that extend beyond said first end, said method comprising:
positioning said prosthesis such that said plurality of wire apices extend across an opening of a renal artery, such that said graft body is not in an intersection of said aortic artery with said renal artery, wherein said opening is where said renal artery joins said aortic artery.
25. The method of claim 24 further comprising expanding a balloon to press said plurality of wire apices against an inner surface of said aortic artery.
