Abstract
Abstract An endoluminal graft which is both expandable and supportive is provided either in a longitudinal form or in a bifurcated form. The graft expands between a first diameter and a second, larger diameter. The support component is an expandable stent endoprosthesis. A cover, liner, or a liner, or both a cover and a liner are applied to the endoprosthesis in the form of a stretchable wall material that is porous, elastomeric and biocompatible in order to allow normal cellular invasion upon implantation, without stenosis, when the expandable and supportive graft is at its second diameter. Preferably, the elastomeric wall material is a polycarbonate urethane.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
110 words
An expandable supportive endoluminal graft comprising: a tubular supporting component with a longitudinal axis having a network of land areas with open areas defined between said land areas, and having an internal surface and an external surface; a liner constructed of an essentially inert biocompatible material, said liner applied to said internal surface; a cover constructed of an essentially inert biocompatible material, said cover applied to said external surface; wherein said liner is bonded to said cover at locations defined by said open areas; and wherein a window is formed through said liner and said cover at a location where said liner and said cover are bonded to each other.
Claim 2
Dependent Claim
110 words
An expandable supportive endoluminal graft comprising: a tubular supporting component with a longitudinal axis having a network of land areas with open areas defined between said land areas, and having an internal surface and an external surface; a liner constructed of an essentially inert biocompatible material, said liner applied to said internal surface; a cover constructed of an essentially inert biocompatible material, said cover applied to said external surface; wherein said liner is bonded to said cover at locations defined by said open areas; and wherein a window is formed through said liner and said cover at a location where said liner and said cover are bonded to each other.
Claim 3
Dependent Claim
36 words
The expandable supportive endoluminal graft of claim 1 wherein said liner and said cover each has a structure that allows normal cellular ingrowth from the body pathway when said expandable supportive endoluminal graft is implanted therein.
Claim 4
Dependent Claim
19 words
The expandable supportive endoluminal graft of claim 1 wherein said cover is substantially supported by said tubular supporting component.
Claim 5
Dependent Claim
131 words
An expandable supportive endoluminal graft comprising: a tubular supporting component with a longitudinal axis having an internal surface and an external surface, said tubular supporting component defining at least one passageway from one end of said tubular supporting component to a second end, said tubular supporting component having a network of land areas with open areas defined therebetween; a liner constructed of an essentially inert biocompatible material, said liner applied to said internal surface; a cover constructed of an essentially inert biocompatible material, said cover applied to said external surface; wherein said liner is bonded to said cover at locations defined by said open areas; and wherein a window is formed through said liner and said cover at a location where said liner and said cover are bonded to each other.
Claim 6
Dependent Claim
131 words
An expandable supportive endoluminal graft comprising: a tubular supporting component with a longitudinal axis having an internal surface and an external surface, said tubular supporting component defining at least one passageway from one end of said tubular supporting component to a second end, said tubular supporting component having a network of land areas with open areas defined therebetween; a liner constructed of an essentially inert biocompatible material, said liner applied to said internal surface; a cover constructed of an essentially inert biocompatible material, said cover applied to said external surface; wherein said liner is bonded to said cover at locations defined by said open areas; and wherein a window is formed through said liner and said cover at a location where said liner and said cover are bonded to each other.
Claim 7
Dependent Claim
19 words
The expandable supportive endoluminal graft of claim 4 wherein said cover is substantially supported by said tubular supporting component.
