ABSTRACT:
A structure suitable for in vivo implantation as a tension member to substitute for tension members such as ligaments and tendons. The structure includes an elongate member which is a biocompatible film, a biocompatible fabric which has a weave having substantially no permanent yield in one direction after said film is formed thereon and a biocompatible porous material which promotes the ingrowth of living tissue and such material is either bonded to the exterior of the elongate member or is contained within and exposed to the exterior. Also disclosed is a structure having a fabric with a film formed thereon and porous ingrowth material bonded to one or both sides thereof to form a patch for in vivo implantation. The film used on the patch may be porous or solid depending on whether the patch is to be permeable to body fluids. The method of making such implantable structures includes the steps of heat forming the plastic film on the fabric folding and forming the combined fabric and film into an elongate structure, bonding the growth material thereto and also inserting heated probes to form apertures in the structure without weakening the fibers of the fabric.
