Abstract
Abstract An implantable intraluminal device includes a multilayer composite tubular device supporting one or more stents between the layer thereof. A first porous elongate tube includes an exterior surface and an interior luminal surface. A radially expandable member is disposed about the exterior surface of the first tube. A second porous elongate tube is disposed concentrically over the first tube and is secured thereto so that the radially expandable member is longitudinally immobilized therebetween.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
135 words
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 the first tube and secured to the exterior surface thereof; and a radially expandable stent disposed between said first and second tubes and being longitudinally immobilized therebetween by securement of said first tube to said second tube and wherein said stent comprises an elongate element with a first end and a second opposed end, said elongate element being formed in a generally circular configuration with said first end immediately adjacent to and overlapping said second end and wherein said first end of said element is moveable with respect to said second end of said element to effect radial expansion.
Claim 2
Dependent Claim
135 words
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 the first tube and secured to the exterior surface thereof; and a radially expandable stent disposed between said first and second tubes and being longitudinally immobilized therebetween by securement of said first tube to said second tube and wherein said stent comprises an elongate element with a first end and a second opposed end, said elongate element being formed in a generally circular configuration with said first end immediately adjacent to and overlapping said second end and wherein said first end of said element is moveable with respect to said second end of said element to effect radial expansion.
Claim 3
Dependent Claim
16 words
The implantable intraluminal device of claim 1, wherein said radially expandable stent includes a longitudinal expanse.
Claim 4
Dependent Claim
20 words

Claim 6
Dependent Claim
27 words
The implantable intraluminal device of claim 4, wherein said bio-compatible metal is selected from the group consisting of stainless steel, platinum, gold, nitinol, tantalum and alloys thereof.
Claim 7
Dependent Claim
15 words
The implantable intraluminal device of claim 1, wherein said first and second tubes are bio-compatible.
Claim 8
Dependent Claim

The implantable intraluminal device of claim 6, wherein said first and second tubes are made from expanded polytetrafluoroethylene.
Claim 9
Dependent Claim
20 words
The implantable intraluminal device of claim 1, wherein said stent is placed adjacent one of said first or second ends.
Claim 10
Dependent Claim
27 words
The implantable intraluminal device of claim 1, wherein a first stent is disposed about said first end and a second stent is disposed about said second end.
Claim 11
Dependent Claim
33 words
The implantable intraluminal device of claim 9, wherein a plurality of stents are disposed about the exterior surface of said first tube and being longitudinally spaced therealong between said first and second stents.
Claim 12
Dependent Claim
19 words
The implantable intraluminal device of claim 1, wherein said second tube is secured to said first tube by fusion.
Claim 13
Dependent Claim
19 words

Claim 14
Dependent Claim
150 words
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 the first tube and secured to the exterior surface thereof; and a radially expandable stent disposed between said first and second tubes and being longitudinally immobilized therebetween by securement of said first tube to said second tube and wherein said stent comprises an elongate element with a first end and a second opposed end having an elongate open-ended channel, said elongate element being formed in a generally circular configuration with said first and second ends of said elongate member being in radial alignment to each other, and wherein said first end of said element can be inserted into said open-ended channel of said second end for movement therein upon radial expansion of said stent.
Claim 15
Dependent Claim
150 words
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 the first tube and secured to the exterior surface thereof; and a radially expandable stent disposed between said first and second tubes and being longitudinally immobilized therebetween by securement of said first tube to said second tube and wherein said stent comprises an elongate element with a first end and a second opposed end having an elongate open-ended channel, said elongate element being formed in a generally circular configuration with said first and second ends of said elongate member being in radial alignment to each other, and wherein said first end of said element can be inserted into said open-ended channel of said second end for movement therein upon radial expansion of said stent.
Claim 16
Dependent Claim
156 words
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 the first tube and secured to the exterior surface thereof; and a radially expandable stent disposed between said first and second tubes and being longitudinally immobilized therebetween by securement of said first tube to said second tube and wherein said stent comprises an elongate element with a first end and a second opposed end, said elongate element being formed in a generally circular configuration with said first end adjacent to and overlapping said second end and wherein an end extent of said first end of said stent includes a plurality of second end engagement means for engaging a distal end of said second end of said stent at plural discrete locations along said end extent for providing finite adjustability therebetween.
