ABSTRACT:
The invention is a composite material of two or more biocompatible polymers, at least one of which is polytetrafluoroethylene (PTFE) and one of which is a bioabsorbable polymer. The nonabsorbable PTFE is used in the composite as a reinforcing binder. The reinforcing binder is a network of unsintered, interconnected micro-fibers which are formed, for example, by blending with a thermoplastic polymer vehicle, such as polymethylmethacrylate which is subsequently extracted. The bioabsorbable component is contained within the structure of the PTFE microfibrils. This composite is useful in the repair of mammalian tissue where tissue ingrowth and permenant support is required.
