Abstract

são revelados materiais finos, biocompatíveis, de alta resistência e compósitos que são adequados para uso em uma válvula protética para regular a direção do fluxo sanguíneo. em um aspecto, o material do folheto mantém flexibilidade em aplicações de flexão de alto ciclo, tornando-o particularmente aplicável a implantes de alta flexão, como um folheto de válvula cardíaca protética. o material folheto inclui uma camada única aderente e um elastômero, em que o elastômero está presente nos poros da camada única porosa e aderente.
