Abstract
A thin, biocompatible, high-strength, composite material is disclosed that is suitable for use in various implanted configurations. The composite material maintains flexibility in high-cycle flexural applications, making it particularly applicable to high-flex implants such as a prosthetic heart valve leaflet. The composite material includes at least one porous expanded fluoropolymer layer and an elastomer present in the pores of the porous expanded fluoropolymer.
