    • A medical device for placing an embolic device at a predetermined site within a vessel of the body including a delivery catheter and a flexible pusher member having a lumen therethrough and being slidably disposed within the lumen of the catheter. An embolic device is retained within the delivery catheter by a mechanical interlocking mechanism which includes an engagement member which is attached to the distal end of the pusher member and extends through a retaining ring at the proximal end of the embolic device. A detachment member extends through an aperture at the distal end of the engagement member thereby locking the embolic device onto the pusher member. When the embolic device is advanced to the predetermined site within the vessel, the detachment member is withdrawn from the aperture to thereby release the embolic device at the treatment site.
    • 一种用于将栓塞装置放置在身体的容器内的预定位置处的医疗装置,包括输送导管和具有通过其的腔的柔性推动器构件,并且可滑动地设置在导管的腔内。 栓塞装置通过机械互锁机构保持在输送导管内,该联动机构包括接合构件,该接合构件附接到推动器构件的远端并延伸穿过栓塞装置的近端处的保持环。 分离构件延伸穿过接合构件的远端处的孔,从而将栓塞装置锁定到推动器构件上。 当栓塞装置前进到血管内的预定位置时,分离构件从孔中取出,从而在治疗部位释放栓塞装置。

    • An occlusive device suitable for endovascular treatment of an aneurysm in a region of a parent vessel in a patient, including a structure having a fixed porosity and having dimensions suitable for insertion into vasculature of the patient to reach the region of the aneurysm in the parent vessel. The device further includes a frangible material supported by the structure which initially provides a substantial barrier to flow through the frangible material and is capable of at least one of localized rupturing and localized eroding, in the presence of a pressure differential arising at an ostium of a perforator vessel communicating with the parent vessel, within an acute time period to minimize ischemia downstream of the perforator vessel.
    • 一种闭塞装置,适用于在患者的母体血管的区域内血管内治疗动脉瘤,包括具有固定孔隙度并具有适于插入患者血管的尺寸的结构,以到达母体血管的动脉瘤区域 。 该装置还包括由结构支撑的易碎材料,其最初提供流过易碎材料的实质屏障,并且能够在存在压力差异的情况下产生局部破裂和局部侵蚀中的至少一种 穿孔器容器在急性期间与母体血管连通,以最小化穿孔器下游的缺血。
