    • A system and method for treating a defect. The system may comprise a first expandable barrier insertable into a defect interior space in a compact state and then expanded once positioned inside the defect. The first expandable barrier is expanded to be positioned against the inner surface of the defect. The system may also comprise a second barrier which may be expandable, positioned against the outer surface of the defect. Each of the first and second barriers may expand laterally to a greater extent than axially. The first and second barriers may be in communication through a connection member which couples the two barriers together. The barriers each obliterate the defect and can prevent subsequent CSF or other fluid leaks. Fibrin glue may be introduced into the defect to seal and secure the barriers to the defect. Each barrier may comprise a mesh, a basket, an umbrella or a balloon.
    • 一种用于处理缺陷的系统和方法。 该系统可以包括第一可膨胀屏障,该第一可膨胀屏障能够以紧凑状态插入缺陷内部空间中,并且随后一旦定位在缺陷内部就膨胀。 第一可膨胀屏障扩展到靠着缺陷的内表面定位。 该系统还可以包括第二屏障,该第二屏障可以是可膨胀的,抵靠缺陷的外表面定位。 第一屏障和第二屏障中的每一个可以比轴向横向地扩展到更大的程度。 第一和第二屏障可以通过将两个屏障连接在一起的连接构件连通。 每个屏障都会消除缺陷并可以防止后续的CSF或其他流体泄漏。 可以将纤维蛋白胶引入缺陷中以密封并固定缺陷的屏障。 每个屏障可以包括网格,篮子,伞或气球。
