    • A surgical fastening apparatus including at least one self-closing clip and a deployment device. The self-closing clip comprises a wire defining an intermediate portion interconnecting opposing, first and second side portions having a memory set loop shape. The deployment device includes a clip holding assembly and an actuator. The clip holding assembly includes first and second containment arms and a transfer rod. The containment arms have a distal segment defining a lumen extending from an open, distal end. The transfer rod is associated with at least one of the containment arms in an axially movable fashion and forms an engagement feature. The actuator is connected to the transfer rod for controlling movement of the rod. Upon final assembly in a pre-deployment state, the engagement feature of the transfer rod engages the intermediate portion of the clip, and the side portions are captured by the containment arms.
    • 一种外科紧固装置,其包括至少一个自闭合夹和展开装置。 自闭合夹具包括限定中间部分的导线,该中间部分互连具有存储器组环形状的相对的第一和第二侧部分。 展开装置包括夹子夹持组件和致动器。 夹子保持组件包括第一和第二容纳臂和转移杆。 容纳臂具有限定从开放的远端延伸的内腔的远侧段。 传递杆以可轴向移动的方式与至少一个容纳臂相关联并且形成接合特征。 致动器连接到传动杆,用于控制杆的移动。 在预先展开状态下最终组装时,传递杆的接合特征与夹子的中间部分接合,并且侧部被容纳臂捕获。

    • This is an implantable vaso-occlusive device. The device has a complex, three-dimensional structure in a relaxed configuration that may be used in the approximate shape of an anatomical cavity. It may be deployed in the approximate shape of a sphere, an ovoid, a clover, a box-like structure or other distorted spherical shape. The loops forming the relaxed configuration may pass through the interior of the structure. The device is a self-forming shape made from a pre-formed linear vaso-occlusion member. Fibers may be introduced onto the device and affixed to the pre-formed linear member. The constituent member may be also be covered with a fibrous braid. The device is typically introduced through a catheter. The device is passed axially through the catheter sheath and assumes its form upon exiting the catheter without further action. The invention also includes methods of winding the anatomically shaped vaso-occlusive device into appropriately shaped forms and annealing them to form various devices.
    • 这是一种植入式血管闭塞装置。 该装置具有可以以解剖腔的近似形状使用的松弛构造中的复杂的三维结构。 它可以以球体,卵球形,三叶草,盒状结构或其它变形球形的大致形状部署。 形成松弛构型的环可以穿过结构的内部。 该装置是由预先形成的线性血管闭塞构件制成的自形成形状。 纤维可以引入到装置上并固定到预成形的线性构件上。 构成部件也可以用纤维编织物覆盖。 该装置通常通过导管引入。 该装置轴向穿过导管护套,并且在离开导管时采取其形式,而无需进一步的动作。 本发明还包括将解剖形状的血管闭塞装置卷绕成适当形状的形状并将其退火以形成各种装置的方法。
