Abstract

"VáLVULA CARDìACA ARTIFICIAL". Uma válvula artificial para corrigir uma válvula cardíaca danificada tendo uma pluralidade de cúspides separando uma região a montante de uma região a jusante. A válvula artificial inclui uma estrutura flexivelmente resiliente dimensionada e formada para a inserção em uma posição entre a região a montante e a região a jusante. A estrutura tem uma pluralidade de apoios periféricos para apoiar a estrutura na posição entre a região a montante e a região a jusante e uma porção central localizada entre a pluralidade de apoios periféricos. A válvula também inclui um elemento de válvula flexível preso na estrutura e na porção central da estrutura tendo um lado a montante confrontando com a região a montante quando a estrutura está apoiada na posição entre a região a montante e a região a jusante e um lado a jusante oposto ao lado a montante confrontando com a região a jusante quando a estrutura está apoiada na posição entre a região a montante e a região a jusante. O elemento de válvula move-se para uma posição aberta quando a pressão do fluido na região a montante é maior do que a pressão do fluido na região a jusante para permitir fluxo a jusante da região a montante para a região a jusante. O elemento de válvula move-se para uma posição fechada quando a pressão do fluido na região a jusante é maior do que a pressão do fluido na região a montante para evitar a inversão do fluxo da região a jusante para a região a montante.
