Abstract
Abstract The present invention provides a soft-tissue prosthesis which is formed from a tubular textile substrate and a liner. The liner is affixed to the intraluminal surface of the tubular textile portion of the soft-tissue prosthesis to form a fluid-tight barrier on the intraluminal surface of the prosthesis. The liner is preferably formed from a polymer. Thus, the soft-tissue prosthesis formed in accordance with the present invention provides the advantages of both a textile prosthesis and a polymer prosthesis.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
94 words
A soft tissue, implantable, tubular prosthesis comprising: a first component comprising a tubular textile substrate consisting essentially of a single material and having an intraluminal surface; and a second component comprising a smooth, microporous liner positioned within and directly in contact with said intraluminal surface of said textile substrate wherein said liner renders the tubular prosthesis substantially fluid-tight and wherein the textile substrate includes fibers having a melting temperature and bonding compatibility substantially similar to a material forming said liner, wherein said liner and said textile substrate are fusibly attached upon application of heat.
Claim 2
Dependent Claim
94 words
A soft tissue, implantable, tubular prosthesis comprising: a first component comprising a tubular textile substrate consisting essentially of a single material and having an intraluminal surface; and a second component comprising a smooth, microporous liner positioned within and directly in contact with said intraluminal surface of said textile substrate wherein said liner renders the tubular prosthesis substantially fluid-tight and wherein the textile substrate includes fibers having a melting temperature and bonding compatibility substantially similar to a material forming said liner, wherein said liner and said textile substrate are fusibly attached upon application of heat.
Claim 3
Dependent Claim
16 words
A soft-tissue prosthesis as defined in claim 1, wherein the liner is formed from a polymer.
Claim 4
Dependent Claim
25 words
A soft-tissue prosthesis as defined in claim 2, wherein the polymer is selected from the group consisting of polytetrafluoroethylene, urethanes, silicones, polyester and mixtures thereof.
Claim 5
Dependent Claim
14 words
A soft-tissue prosthesis as defined in claim 2, wherein the polymer is expanded polytetrafluoroethylene.
Claim 6
Dependent Claim
34 words
A soft-tissue prosthesis as defined in claim 1, wherein the liner includes an inner surface and an outer surface defining a wall thickness, said wall thickness being sufficient to make the tubular prosthesis fluid-tight.
Claim 7
Dependent Claim
29 words
A soft-tissue prosthesis as defined in claim 1, wherein the textile substrate is selected from the group consisting of woven, knitted or braided yarns to form a tubular structure.
Claim 8
Dependent Claim
18 words
A soft-tissue prosthesis as defined in claim 6, wherein the textile substrate is formed from a thermoplastic polymer.
Claim 9
Dependent Claim
27 words
A soft-tissue prosthesis as defined in claim 7, wherein the thermoplastic polymer is selected from the group consisting of polyesters, polytetrafluoroethylene, polyethylenes, polyurethanes, polypropylenes and mixtures thereof.
Claim 10
Dependent Claim
18 words
A soft-tissue prosthesis as defined in claim 1, wherein the textile substrate includes at least one bioabsorbable component.
Claim 11
Dependent Claim
24 words
A soft-tissue prosthesis as defined in claim 1, wherein the textile substrate includes a colored axial yarn as a visual alignment aid during implantation.
Claim 12
Dependent Claim
36 words
A soft-tissue prosthesis as defined in claim 1, wherein the textile substrate includes a fusible fiber having a low melting temperature, lower than the textile substrate such that when heated, the fiber fuses to said liner.
Claim 13
Dependent Claim
43 words
A soft-tissue prosthesis as defined in claim 11, wherein the liner contains micropores and wherein the fusible fiber has melt flow properties which allow the melted fiber to flow into the micropores of the liner, thereby securing said liner to said textile substrate.
Claim 14
Dependent Claim
18 words
A soft-tissue prosthesis as defined in claim 1, wherein the textile substrate is a woven single-velour tubular structure.
Claim 15
Dependent Claim
29 words
A soft-tissue prosthesis as defined in claim 1, wherein the textile substrate is a woven singular-velour tubular structure having a velour on an outer surface of said textile substrate.
