Abstract
Methods are presented that provide a thin, biocompatible, high-strength, composite material that is suitable for use in prosthetic valves. The composite material maintains flexibility in high-cycle flexural applications, making it particularly applicable to prosthetic valve leaflets. The composite material includes more than one porous expanded fluoropolymer layer and an elastomer present in the pores of the porous expanded fluoropolymer.
