Abstract

La invención está relacionada con un dispositivo de stent y un sistema de stent. El dispositivo de stent incluye un stent y un mecanismo de sujeción. El stent incluye una porción principal y una porción ramificada proporcionada en la porción principal, y la porción ramificada se proporciona con una parte de conexión; el mecanismo de sujeción incluye una parte de tracción que tiene un extremo proximal configurado para conectarse con la parte de conexión, y un extremo distal configurado para conectarse con un mecanismo externo de posicionamiento; la parte de tracción está configurada para aplicar una fuerza de tracción sobre la parte de conexión bajo la acción del mecanismo externo de posicionamiento para así mantener el stent en una posición predeterminada, por lo cual se evita que el stent se desplace durante la operación quirúrgica y la extracción del dispositivo de entrega.
