    • A catheter for a self-expanding stent includes a proximal shaft with a longitudinal guide way along the length of the proximal shaft, a guide member for accessing a guidewire lumen defined by the proximal shaft and for drawing a guidewire into and out of the guidewire lumen along the proximal shaft. In one aspect, the catheter includes a proximal sliding mechanism coupled to a link, which is coupled to a distal outer shaft retaining a self-expanding stent in a compressed state. The sliding mechanism draws the link proximally, which draws the distal outer shaft proximally thereby allowing the stent to radially expand. In another aspect, the proximal sliding mechanism is coupled to a proximal shaft, which is coupled to the distal outer shaft. The sliding mechanism draws the proximal shaft proximally, which draws the distal outer shaft proximally to thereby allow the stent to radial expand.
    • 用于自扩张支架的导管包括:近轴,其具有沿着近端轴的长度的纵向引导方式;导向构件,用于接近由近端轴限定的导丝腔,并用于将导丝拉入和拉出导丝管腔 沿近轴。 在一个方面,导管包括联接到连杆的近侧滑动机构,其联接到保持处于压缩状态的自扩张支架的远侧外轴。 滑动机构向近侧拉伸连杆,其将远端外轴向近侧拉出,从而允许支架径向扩张。 在另一方面,近侧滑动机构联接到近端轴,该近端轴联接到远侧外轴。 滑动机构向近侧拉近近端轴,其将近端外轴向近侧拉动,从而允许支架径向膨胀。
