    • The invention is directed to a self-expanding stent for implantation into a body lumen, such as an artery. The stent consists of a plurality of radially expandable cylindrical elements generally aligned on a common longitudinal stent axis and interconnected by a plurality of interconnecting members placed on the stent in a collinear arrangement such as to create at least one continuous spine which extends along the length of the stent. The invention is also directed to a stent delivery system for implantation of a stent in a vessel which includes an outer tubular member having a restraining sheath and an inner tubular member having a distal end which has a compressed stent mounted thereto. The proximal end of the inner tubular member is connected to a housing assembly which prevents the inner tubular member from moving when the outer tubular member is retracted to deploy the stent. The proximal end of the outer tubular member is attached to a pull-back handle which is slidably mounted on the base of the housing assembly. When the pull-back handle is retracted, the restraining sheath is retracted to deploy the sheath, while the inner tubular member remains stationary.
    • 本发明涉及用于植入体腔如动脉的自扩张支架。 支架由多个可径向扩张的圆柱形元件组成,通常在共同的纵向支架轴线上对准并且通过以共线布置放置在支架上的多个互连构件相互连接,以产生至少一个连续的脊柱,其沿着 支架 本发明还涉及用于将支架植入容器中的支架输送系统,该支架包括具有约束护套的外管状构件和具有安装在其上的压缩支架的远端的内管状构件。 内部管状构件的近端连接到壳体组件,当外部管状构件缩回以展开支架时,壳体组件防止内部管状构件移动。 外管状构件的近端附接到可滑动地安装在壳体组件的基部上的拉回手柄。 当拉回手柄缩回时,约束护套被缩回以展开护套,同时内部管状构件保持静止。
