Abstract

La invención proporciona una vaina de derivación y un dispositivo de colocación de stent de derivación. El extremo proximal de la bobina de restricción en la vaina de derivación está conectado al extremo distal del tubo de conexión, y el extremo distal de la bobina de restricción atraviesa y se extiende fuera del manguito. El extremo distal de la bobina de restricción está configurado para extenderse fuera del extremo desnudo del stent de derivación desde la abertura del mismo, para tirar y asegurar el extremo desnudo del stent de derivación comprimido. Esto evita que el stent principal tire del stent de derivación para provocar un desplazamiento después de que se haya liberado el stent principal. El cable de control se extiende a través de la parte de la bobina de restricción que se extiende fuera del extremo desnudo desde la abertura del mismo, para controlar la liberación del stent de derivación. Después de que el stent de derivación esté fuera de la posición predeterminada durante la operación, el cable de control también se puede volver a colocar en el vaso de la derivación en cualquier momento, logrando un posicionamiento preciso. El extremo proximal de la primera bobina de fijación está conectado con el extremo distal del tubo de conexión, y el extremo distal de la primera bobina de fijación está conectado con el stent principal, lo que permite colocar la vaina de derivación como un todo. Por lo tanto, el dispositivo de colocación de la vaina de derivación y el stent de derivación según la presente invención no solo puede evitar que el stent de derivación se desplace y garantizar una posición precisa para la liberación, sino que también puede operarse fácilmente con una implementabilidad aumentada.
