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: 12
Claim 1
Independent Claim
96 words
A soft-tissue, implantable, tubular prosthesis comprising: a first component comprising a tubular textile substrate having a textile pattern and an intraluminal surface, said textile substrate incorporating a fusible fiber into said textile pattern, said fusible fiber having a melting temperature below that of said textile substrate; 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 said tubular prosthesis substantially fluid-tight and wherein said fusible fiber is capable of fusing and thereby securing said liner to said textile substrate.
Claim 2
Dependent Claim
96 words
A soft-tissue, implantable, tubular prosthesis comprising: a first component comprising a tubular textile substrate having a textile pattern and an intraluminal surface, said textile substrate incorporating a fusible fiber into said textile pattern, said fusible fiber having a melting temperature below that of said textile substrate; 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 said tubular prosthesis substantially fluid-tight and wherein said fusible fiber is capable of fusing and thereby securing said liner to said textile substrate.
Claim 3
Dependent Claim
37 words
A soft-tissue prosthesis as defined in claim 1, wherein said fusible fiber is a bi-component fiber having a core and a sheath, said sheath having a melting temperature below that of said core and said textile substrate.
Claim 4
Dependent Claim
45 words
A soft-tissue prosthesis as defined in claim 1, wherein said liner contains micropores and wherein said fusible fiber has melt flow properties which allow said fusible fiber to flow into the micropores of said liner upon melting, thereby securing said liner to said textile substrate.
Claim 5
Dependent Claim
16 words
A soft-tissue prosthesis as defined in claim 1, wherein said liner is formed from a polymer.
Claim 6
Dependent Claim
26 words
A soft tissue prosthesis as defined in claim 4, wherein said polymer is selected from the group consisting of polytetrafluoroethylene, urethanes, silicones, polyester and mixtures thereof.
Claim 7
Dependent Claim
34 words
A soft-tissue prosthesis as defined by claim 1, wherein said liner includes an inner surface and an outer surface defining a wall thickness, said wall thickness being sufficient to make said tubular prosthesis fluid-tight.
Claim 8
Dependent Claim
29 words
A soft-tissue prosthesis as defined in claim 1, wherein said textile substrate is selected from the group consisting of woven, knitted and braided yarns to form a tubular structure.
Claim 9
Dependent Claim
18 words
A soft-tissue prosthesis as defined in claim 7, wherein said textile substrate is formed from a thermoplastic polymer.
Claim 10
Dependent Claim
27 words
A soft-tissue prosthesis as defined in claim 8, wherein said thermoplastic polymer is selected from the group consisting of polyesters, polytetrafluoroethylene, polyethylenes, polyurethanes, polypropylenes, and mixtures thereof.
Claim 11
Dependent Claim
18 words
A soft-tissue prosthesis as defined in claim 1, wherein said textile substrate includes at least one bioadsorbable component.
Claim 12
Dependent Claim
25 words
A soft tissue prosthesis as defined in claim 1, wherein said textile substrate includes a colored axial yarn as a visible alignment aid during implantation.
