Abstract

cobertura multicamada para uma válvula cardíaca protética. a presente invenção refere-se a uma válvula cardíaca protética incluindo uma armação, estrutura do folheto e elemento de vedação disposto em torno de uma superfície externa da armação, que é divulgada. como um exemplo, o elemento de vedação inclui uma camada interna e uma camada externa felpuda compreendendo uma superfície externa felpuda. a camada interna está disposta contra a superfície externa da armação e a camada externa está disposta contra e ligada à camada interna. a camada interna é dobrada sobre as extremidades de influxo e escoamento, em uma direção axial em relação a um eixo longitudinal central da armação, para se sobrepor às respectivas extremidades da camada externa e formar dobras afuniladas nas extremidades opostas do elemento de vedação, cada dobra afunilada incluindo uma primeira parte mais estreita onde a camada interna se dobra e entra em contato com ela mesma e uma segunda parte mais ampla onde a camada interna se sobrepõe a uma superfície externa de uma parte de extremidade da camada externa.
