Abstract: Described are systems for delivering embolic coil devices, and components useful in such systems. The systems include a flexible elongate delivery shaft having a distal region and an embolic coil device detachably connected to the distal region of the elongate delivery shaft. In some forms, as detachably connected, at least some of the coil windings of the embolic coil device, such as those in a proximal segment of the coil windings, are in a resiliently longitudinally compressed condition. When the embolic coil device is detached from the delivery shaft, the coil windings resiliently move to a longitudinally extended condition, where the coil windings in the longitudinally extended condition are more open than they are in the resiliently longitudinally compressed condition. In some forms, the systems have a coil detachment interface at a distal region of a flexible elongate delivery shaft. The coil detachment interface includes a distal tubular segment and a bridge segment proximal of the distal tubular segment. The bridge segment includes a bridge wall or other bridge component defining an upper surface, a lower surface, a proximally-facing edge spanning between the upper surface and the lower surface, and a distally-facing edge spanning between the upper surface and the lower surface. The bridge segment further defines a lumen between the lower surface of the bridge wall or other bridge component and a bottom wall of the bridge segment. Also described are embolic coil devices and bridge members configured for use in such systems.

Abstract: A stent for use in a medical procedure having opposing sets of curved apices, where the curved section of one set of apices has a radius of curvature that is greater than the curved section of the other set of apices. One or more such stents may be attached to a graft material for use in endovascular treatment of, for example, aneurysm, thoracic dissection, or other body vessel condition.
Abstract translation: 一种用于医疗过程的支架，其具有相对的一组曲面顶点，其中一组顶点的弯曲部分的曲率半径大于另一组顶点的弯曲部分。 一个或多个这样的支架可以附着到移植物材料上，以用于血管内治疗例如动脉瘤，胸部解剖或其它身体血管状态。

Abstract: A vascular occluder includes a tubular support element and a sleeve of occluding material disposed within the support element. The sleeve is twisted in the support creating a constriction which closes the lumen of the sleeve. The lumen of the sleeve can nevertheless be opened by a guide wire or cannula for over the wire delivery. Once the guide wire or cannula are withdrawn from the sleeve, the sleeve will close again by the action of blood pressure thereon. Blood pressure will act to maintain closing pressure on the sleeve, thereby avoiding or reducing the risk of recanalization.

Abstract: An embolic coil delivery system includes a delivery shaft that defines a delivery shaft lumen and an embolic coil device that is detachably connected to a distal region of the delivery shaft. The embolic coil device includes coil windings that define a coil lumen. A pull wire is positioned at least partially within the delivery shaft lumen and at least partially within the coil lumen. The pull wire includes a frangible segment that is positioned within the coil lumen. The frangible segment of the pull wire defines a predictable region of separation of the pull wire in response to tensile force so as to detach said embolic coil device from said delivery shaft.

Abstract translation: 血管阻塞器包括管状支撑元件和设置在支撑元件内的阻塞材料的套筒。 套筒在支撑件中扭转，形成一个闭合套管内腔的收缩部。 然而，套管的内腔仍然可以通过导丝或套管打开以用于导线输送。 一旦引导线或插管从套筒中取出，套管将再次通过其上的血压作用而关闭。 血压将起到保持袖套上的关闭压力的作用，从而避免或降低再通风险。
