Abstract

An implantable intraluminal device (10) includes a first porous elongate tube (12) with first and second opposed ends (14, 16) and an exterior surface and an interior luminal surface. A radially expandable member (28) is disposed about the exterior surface of the first tube. A second porous elongate tube (22) is disposed concentrically over the first tube and the radially expandable member and is secured to the first tube so that the radially expandable member is transversely mobile within a pocket (30) formed by the securement of the first tube to the second tube.

Claims

AMENDED CLAIMS[received by the International Bureau on 22 July 1998 (22.07.98); original claims 1 and 14 amended; remaining claims unchanged (5 pages)]
1. An implantable intraluminal device comprising: a first porous elongate tube having first and second opposed ends, said first tube having an exterior surface and an interior luminal surface; a second porous elongate tube disposed concentrically over said first tube, said first and second tubes defining an elongate expandable prosthesis; said first tube secured to said second tube to form a longitudinally extending pocket therebetween; and a generally annular radially expandable member disposed about the exterior surface of said first tube and located within said pocket, wherein said pocket has a longitudinal expanse greater than a longitudinal expanse of said radially expandable member, whereby said expandable member is longitudinally moveable within said pocket.
2. The implantable intraluminal device of claim 1, wherein said generally annular radially expandable member is a stent.
3. The implantable intraluminal device of claim 1 , wherein said first tube is secured to said second tube at secured locations adjacent each of said ends to form said pocket between said secured locations.
4. The implantable intraluminal device of claim 1 , wherein said first tube is secured to said second tube at a plurality of longitudinally spaced locations to form one of said pockets between each adjacent secured location.
17
5. The implantable intraluminal device of claim 1 , wherein each of said pockets support a single stent.
6. The implantable intraluminal device of claim 1 , wherein each of said pockets support a plurality of stents.
7. The implantable intraluminal device of claim 2, wherein said stent is a bio- compatible metal.
8. The implantable intraluminal device of claim 7, wherein said bio- compatible metal is selected from the group consisting of stainless steel, platinum, gold, nitinol, tantalum and alloys thereof.
9. The implantable intraluminal device of claim 1 , wherein said first and second tubes are bio-compatible.
10. The implantable intraluminal device of claim 1, wherein said first and second tubes are fabricated of expanded polytetrafiuoroethylene.
11. The implantable intraluminal device of claim 1 , wherein said first and said second tubes are secured to each other by fusion.
18
12. The implantable intra-luminal device of claim 1, wherein said first and said second tubes are secured to each other by lamination.
13. The implantable intraluminal device of claim 1, wherein said device is a balloon expandable device.
14. A process for providing an implantable intraluminal device comprising: a) providing a first porous tube having first and second opposed ends, said first tube having an exterior surface and an interior luminal surface; b) disposing a generally annular radially expandable member about the exterior surface of said first tube; c) positioning a second porous tube concentrically over said first tube and said expandable member; d) securing said first tube to said second tube at spaced apart locations to form a longitudinally extending pocket between said first and second tubes wherein said pocket has a longitudinal expanse greater than a longitudinal expanse of said radially expandable member and said expandable member is longitudinally movably confined within said pocket.
15. The process of claim 14, wherein said generally annular radially expandable member is a stent.
16. The process of claim 14, wherein said securing step includes securing said first tube to said second tube at secured locations adjacent each of said ends and forming said pocket between said secured locations.
19
17. The process of claim 14, wherein said securing step further includes securing said first tube to said second tube at a plurality of longitudinally spaced secured locations and forming one of said pockets between each adjacent secured location.
18. The process of claim 14, wherein said securing step further includes supporting a single stent in each of said pockets.
19. The process of claim 14, wherein said securing step further includes supporting a plurality of stents in each of said pockets.
20. The process of claim 15, wherein said stent is a bio-compatible metal.
21. The process of claim 20, wherein said bio-compatible metal is selected from the group consisting of stainless steel, platinum, gold, nitinol, tantalum and alloys thereof.
22. The process of claim 14, wherein said first and second tubes are bio- compatible.
23. The process of claim 14, wherein said first and second tubes are expanded polytetrafluoroethylene.
20
24. The process of claim 14, wherein said securing step further includes fusing said first tube to said second tube at spaced apart locations to form a longitudinally extending pocket between said first and second tubes wherein said expandable member is longitudinally movably confined within said pocket.
25. The process of claim 14, wherein said securing step further includes laminating said first tube to said second tube at spaced apart locations to form a longitudinally extending pocket between said first and second tubes wherein said expandable member is longitudinally movably confined within said pocket.
