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.
Claims14
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.
