Abstract
La presente invención proporciona una vaina de rama y un sistema de introducción. La vaina de rama incluye una estructura de control, un manguito, una bobina de retención y un tubo de conexión. La estructura de control incluye un primer tubo de retención y un cable guía de rama. El tubo de conexión incluye un segundo tubo de retención y un tercer tubo de retención. El extremo proximal del segundo tubo de retención recubre el extremo distal del primer tubo de retención, y el extremo distal del segundo tubo de retención recubre el cable guía de rama y se extiende hasta una parte exterior del manguito. El extremo proximal del tercer tubo de retención recubre el extremo distal del manguito. El extremo distal de la bobina de retención está fijado al extremo proximal de la estructura de control y el extremo proximal de la bobina de retención se extiende hasta una parte exterior del manguito. El sistema de introducción incluye la vaina de rama como se describió más arriba. La presente invención puede no solo reducir efectivamente la resistencia a la liberación del stent de rama y el diámetro exterior total de la vaina de rama, sino también mejorar la fuerza de conexión entre el manguito y la estructura de control, lo cual hace que la estructura general de la vaina de rama sea más estable y mejora efectivamente la tasa de éxito en la liberación del stent de rama.The present invention provides a branch sheath and an introduction system. The branch sheath includes a control structure, a sleeve, a retaining coil and a connecting tube. The control structure includes a first retaining tube and a branch guide wire. The connecting tube includes a second retention tube and a third retention tube. The proximal end of the second retention tube overlies the distal end of the first retention tube, and the distal end of the second retention tube overlies the branch guide wire and extends to an exterior portion of the cuff. The proximal end of the third retention tube overlies the distal end of the cuff. The distal end of the retention coil is secured to the proximal end of the control structure and the proximal end of the retention coil extends to an outer portion of the sleeve. The introduction system includes the branch sheath as described above. The present invention can not only effectively reduce the release resistance of the branch stent and the total outer diameter of the branch sheath, but also improve the connection strength between the sleeve and the control structure, which makes the structure overall branch sheath more stable and effectively improves the success rate of branch stent release.
