    • A vasoocclusive embolic delivery system for use in placement of an embolic coil at a treatment site within a vessel. The embolic coil includes an elongated stretch resistant fiber having its distal end bonded to the distal end of the embolic coil. The stretch resistant fiber extends through a central lumen of the coil and extends beyond the proximal end of the coil. Also included is a generally cylindrical stabilization bead, having a diameter slightly smaller than the diameter of the central lumen of the coil, mounted on the stretch resistant fiber within the lumen of the embolic coil. The stabilization bead serves to keep the stretch resistant fiber centered within the lumen of the embolic coil. Additionally, a headpiece is mounted on the proximal end of the stretch resistant fiber and serves to couple the embolic coil to the delivery system.
    • 一种用于在血管内的治疗部位放置栓塞线圈的血管闭塞栓塞递送系统。 栓塞线圈包括细长的抗拉纤维,其远端结合到栓塞线圈的远端。 抗拉纤维延伸穿过线圈的中心腔并延伸超过线圈的近端。 还包括一般为圆柱形的稳定化珠,其直径略小于线圈的中心腔的直径,安装在栓塞线圈内腔内的抗拉纤维上。 稳定珠用于将抗拉纤维保持在栓塞线圈的内腔中心。 此外,头盔安装在抗拉纤维的近端上,并用于将栓塞线圈耦合到输送系统。
