    • A delivery system for delivering and deploying a stent graft includes a guidewire catheter, an apex release catheter, an apex capture device, a relatively rigid, hollow catheter, a sheath catheter, a relatively flexible, hollow stent graft sheath and a distal nose. The apex capture device includes a distal capture portion fixedly connected to the distal end of the guidewire catheter and having a distal portion and a proximal stopper having an exposed side facing distally in a plane approximately perpendicular to a longitudinal axis of the guidewire catheter. The apex capture device also includes a proximal capture portion fixedly connected to the distal end of the apex release catheter and has fingers extending toward the distal capture portion in a distal direction that define an interior cavity to receive the proximal stopper. The proximal and distal capture portions of the apex capture device define a stent capture state. In an embodiment, the delivery system further includes a hollow graft push catheter slidably disposed about the apex release catheter and a connected to the distal end of the graft push catheter.
    • 用于递送和部署支架移植物的递送系统包括导丝导管,顶点释放导管,顶点捕获装置,相对刚性的中空导管,鞘导管,相对柔性的中空支架移植鞘和远端鼻。 顶点捕获装置包括固定地连接到导丝导管的远端的远侧捕获部分,并且具有远侧部分和近端止动器,该远端部分和近端止动器具有面向远端的暴露侧面,该平面大致垂直于导丝导管的纵向轴线。 顶点捕获装置还包括固定地连接到顶点释放导管的远端的近端捕获部分,并且具有在远侧方向上朝向远端捕获部分延伸的指状物,该远端方向限定内腔以容纳近端塞。 顶点捕获装置的近端和远端捕获部分限定支架捕获状态。 在一个实施例中,输送系统还包括可滑动地设置在顶点释放导管周围并连接到移植物推动导管的远端的中空移植物推送导管。
