ABSTRACT:
High-strength, high-modulus, polymeric implants are produced from highly oriented monofilaments and/or films by solvent welding technique. This avoids loss of orientation, as well as thermal and oxidative degradation, which is the common case with the state of art techniques, namely melt extrusion, injection molding and heat compression molding. The invention leads to uniform bonding of the separate structural units (monofilaments or films) into compound-filament or compound-laminate which protects the implant against delamination. Monofilaments of films are swollen at the surface with a suitable solvent which does not destroy the orientation in the core. A bundle, resp. a sandwich of the swollen monofilaments or films is pulled through an orifice generating compressive stresses between the filaments, resp. films. Solvent removal from the swollen compressed interfaces leads to a homogenous welding of the monofilaments or films.
