Abstract

dispositivo de stent para uma válvula cardíaca protética. a presente invenção pertence ao campo da substituição de uma válvula cardíaca atrioventricular defeituosa, em particular uma válvula tricúspide, incluindo dispositivos de stent, válvulas cardíacas protéticas, sistemas de entrega e métodos correspondentes, que fornecem uma fixação melhorada sem distorção da anatomia nativa da válvula tricúspide. consequentemente, um dispositivo de stent (10) para uma válvula cardíaca protética é sugerido, compreendendo um corpo em forma de malha (12) que se estende em uma direção axial, em que o corpo (12) é configurado para encaixar em um orifício e define um canal interno (15) para fornecer uma passagem a partir de uma extremidade proximal (16) para uma extremidade distal (17) do corpo (12), e pelo menos três braços de suporte externos (18) se estendendo a partir do corpo (12) a partir da extremidade distal (17) do corpo (12) para a extremidade proximal (16), em que cada braço de suporte (18) compreende uma primeira região de suporte (20) na extremidade distal (17), e uma segunda região de suporte (22) na extremidade proximal (16), em que a segunda região de suporte (22) se estende radialmente para fora no estado implantado. cada braço de suporte (18) compreende uma região flexível (24) entre a primeira região de suporte (20) e a segunda região de suporte (22), que é formada como uma seção afunilada do braço de suporte (18) em uma direção axial e / ou cada braço de suporte (18) é afunilado em direção à extremidade proximal (16).
