Abstract

a presente invenção refere-se a uma válvula cardíaca protética que inclui uma estrutura anelar que tem uma extremidade de entrada e uma extremidade de saída e é radialmente compressível e expansível entre uma configuração comprimida radialmente e uma configuração expandida radialmente. a válvula cardíaca protética inclui ainda uma estrutura de folheto posicionada dentro da estrutura e presa à mesma, e um elemento de vedação externo montado fora da estrutura e adaptado para vedar contra o tecido circundante quando a válvula cardíaca protética é implantada dentro de um anel de válvula cardíaca nativa de um paciente. o elemento de vedação pode incluir uma camada de malha e uma camada de pelo compreendendo uma pluralidade de fios de pelo que se estendem para fora a partir da camada de malha.
