Abstract
estrutura de válvula cardíaca protética com comissões flexíveis. uma válvula protética pode incluir possuindo uma parte de forma de fio e uma parte de stent. as partes em forma de fio e de stent podem ser acopladas de forma não destacável através de uma pluralidade de longarinas retas de modo a formar não destacável através de uma pluralidade de longarinas retas de modo a formar uma estrutura de válvula cardíaca protética de peça única. alternativamente, uma parte de forma de fio de expansão automática e uma parete de stent expansível tipo balão podem ser acopladas através de uma ou mais cúspides e um subconjunto possuindo um stent de suporte de cúspide flexível e um anel de vedação. a parte de forma de fio incluir cúspides e comissuras configuradas para suportat a pluralidade de cúspides. a válvula protética pode ser radialmente desmontável para técnicas de distribuição transcatéter e/ou minimamente invasivas. as modalidades descritas também podem fornecer flexão da parte de forma de fio (por exemplo, das comissuras) em resposta ao carregamento púlsatil fisiológico quando a válvula é implantada no anel de válvula nativa de um paciente. métodos de fabricação e utilização de válvulas cardíacas protéticas também são descritos.
