Abstract

Ejemplos de dispositivos de reparación de válvulas para reparar una válvula nativa de un paciente incluyen porciones de coaptación expandibles. Una porción de coaptación tiene una abertura y una porción expandible que está configurada para expandirse hacia afuera a través de la abertura. Un elemento de accionamiento o miembro de accionamiento se acopla con la parte expandible para expandir y retraer la parte expandible. Otra porción de coaptación expandible tiene un eje central, un tubo de accionamiento y un espaciador expandible. Un primer extremo del espaciador expandible está asegurado al eje central. Un segundo extremo del espaciador expandible está asegurado al tubo de bloqueo. La rotación del tubo de accionamiento con respecto al eje central hace que se expanda el espaciador expansible
