    • 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。
