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 control. El mecanismo de control incluye un alambre guía y una porción de tracción dispuesta en el alambre guía. El alambre guía se extiende a lo largo de una dirección axial del stent y se dispone de forma móvil en la pared interior del stent; el stent tiene una fenestración, el stent también tiene una porción de conexión y una porción limitante, y la porción de conexión se proporciona en un lado del stent donde está ubicada la fenestración y está configurada para conectarse con la porción de tracción; la porción limitante está configurada para limitar la posición del alambre guía en las direcciones circunferencial y radial del stent; cuando el stent se encuentra en estado expandido, el alambre guía aplica una fuerza de tracción a la porción de conexión a través de la porción de tracción, de modo que la pared del stent alrededor de la fenestración se encastra en la cavidad interior del stent, por lo cual está separada de la pared del vaso, y evita la isquemia en el vaso ramificado provocada por un bloqueo del vaso ramificado que resulta de una inexacta alineación entre la fenestración y el vaso ramificado.The invention relates to a stent device and a stent system. The stent device includes a stent and a control mechanism. The control mechanism includes a guide wire and a traction portion disposed on the guide wire. The guidewire extends along an axial direction of the stent and is movably arranged on the inner wall of the stent; the stent has a fenestration, the stent also has a connecting portion and a limiting portion, and the connecting portion is provided on a side of the stent where the fenestration is located and is configured to connect with the pulling portion; the limiting portion is configured to limit the position of the guidewire in the circumferential and radial directions of the stent; when the stent is in an expanded state, the guide wire applies a pulling force to the connecting portion through the pulling portion, so that the stent wall around the fenestration is embedded in the inner cavity of the stent, thus it is detached from the vessel wall, and prevents ischemia in the branch vessel caused by blockage of the branch vessel resulting from inaccurate alignment between the fenestration and the branch vessel.
