Abstract
Abstract A prosthesis comprising a graft and an expandable stent underlying the graft, the stent and graft being linked together only at or near their distal ends. The difference in stent length between compressed and expanded radial configurations may exceed the difference in graft length between such configurations. An introducer for such prosthesis comprises an interior sheath axially mounted inside an exterior sheath, with the graft positioned between the interior and exterior sheaths and the stent compressed at least partially inside the interior sheath. A method for deploying the prosthesis using such an introducer may include positioning the introducer distal end upstream relative to proximally flowing endoluminal fluid so that the endoluminal fluid may flow between the graft and inner sheath during stent deployment.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
99 words
A prosthesis adapted for deployment inside a body lumen in a distal deployment location from a proximal access location outside the body lumen, the prosthesis comprising: a graft having flexible walls and a distal end; and an expandable stent underlying said graft and having a distal end, wherein said stent and said graft are linked together only at or near the distal end of said stent and the distal end of said graft, and said prosthesis is adapted to allow endoluminal fluid flow proximally across said stent and within the walls of said graft during deployment of said prosthesis.
Claim 2
Dependent Claim
99 words
A prosthesis adapted for deployment inside a body lumen in a distal deployment location from a proximal access location outside the body lumen, the prosthesis comprising: a graft having flexible walls and a distal end; and an expandable stent underlying said graft and having a distal end, wherein said stent and said graft are linked together only at or near the distal end of said stent and the distal end of said graft, and said prosthesis is adapted to allow endoluminal fluid flow proximally across said stent and within the walls of said graft during deployment of said prosthesis.
Claim 3
Dependent Claim
66 words
The prosthesis of claim 1 wherein: said stent has a first axial length in a compressed radial configuration and a second axial length in an expanded radial configuration, the first axial length of the stent exceeding the second axial length of the stent; and said graft has a first axial length in a compressed radial configuration and a second axial length in an expanded radial configuration.
Claim 4
Dependent Claim
24 words
The prosthesis of claim 2 wherein the first axial length of the graft is essentially equal to the second axial length of the graft.
Claim 5
Dependent Claim
27 words
The prosthesis of claim 2 wherein the first axial length of the graft exceeds the second axial length of the graft by a difference in graft length.
Claim 6
Dependent Claim
39 words
The prosthesis of claim 4 wherein the first axial length of the stent exceeds the second axial length of the stent by a difference in stent length and the difference in stent length exceeds the difference in graft length.
Claim 7
Dependent Claim
23 words
The prosthesis of claim 2 wherein the second axial length of the stent is greater than the second axial length of the graft.
Claim 8
Dependent Claim
27 words
The prosthesis of claim 1 wherein the graft distal end is attached near the stent distal end at a location proximally spaced from the stent distal end.
Claim 9
Dependent Claim
22 words
The prosthesis of claim 1 wherein the stent comprises a thermosensitive self-expanding stent or a stent that is self-expanding through structural elasticity.
Claim 10
Dependent Claim
19 words
The prosthesis of claim 1 wherein said graft and said stent are linked together at a single axial location.
Claim 11
Dependent Claim
16 words
The prosthesis of claim 1 wherein the stent underlies the graft approximately co-extensively with the graft.
Claim 12
Dependent Claim
12 words
The prosthesis of claim 1 wherein the stent comprises a solitary stent.
Claim 13
Dependent Claim
115 words
A prosthesis adapted for deployment inside a body lumen in a distal deployment location from a proximal access location outside the body lumen, the prosthesis comprising: a graft having flexible walls, a distal end, a first axial length in a compressed radial configuration, and a second axial length in an expanded radial configuration; an expandable stent underlying said graft and having a proximal end, a distal end, a first axial length in a compressed radial configuration, and a second axial length in an expanded radial configuration, the first axial length of the stent exceeding the second axial length; wherein said stent and said graft are linked together only at or near the distal ends thereof.
Claim 14
Dependent Claim
115 words
A prosthesis adapted for deployment inside a body lumen in a distal deployment location from a proximal access location outside the body lumen, the prosthesis comprising: a graft having flexible walls, a distal end, a first axial length in a compressed radial configuration, and a second axial length in an expanded radial configuration; an expandable stent underlying said graft and having a proximal end, a distal end, a first axial length in a compressed radial configuration, and a second axial length in an expanded radial configuration, the first axial length of the stent exceeding the second axial length; wherein said stent and said graft are linked together only at or near the distal ends thereof.
Claim 15
Dependent Claim
74 words
A prosthesis adapted for deployment inside a body lumen in a distal deployment location from a proximal access location outside the body lumen, the prosthesis consisting of: a graft having flexible walls and a distal end; an expandable stent underlying said graft and having a distal end, and a link at or near the distal end of said stent and the distal end of said graft for linking said stent and said graft together.
Claim 16
Dependent Claim
