Abstract
Abstract A valve adapted to be inserted into an interior passage of a living creature, such as a vas valve. The valve has inner and outer components with said outer component carrying at an exterior surface thereof a structure for promoting ingrowth of tissue into tight engagement with the exterior surface of the outer component. This structure for promoting the ingrowth of tissue may take the form of a fine gold wire which is wound around and carried by the exterior valve component or it may take the form of a body carried by the exterior surface of the outer component and having pores which are sufficiently great for promoting the ingrowth of tissue.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
138 words
For use in the body of a living creature, valve means adapted to be inserted into an interior passage of the body for controlling the flow of fluid therethrough, and filamentary means extending around and carried by an exterior surface of said valve means for promoting ingrowth of tissue into tight engagement with said exterior surface, said exterior surface surrounding a given axis and said filamentary means being wound continuously around and engaging said exterior surface without interruption circumferentially around said axis, said living creature being a human being and said valve means being small enough to be inserted into a human vas and being made of a material compatible with the interior of the body, said valve means having outer and inner components and said filamentary means being carried by said outer component of said valve means.
Claim 2
Dependent Claim
