    • Described is a medical device and method for allowing fenestration of the aortic wall while maintaining distal perfusion and preventing external bleeding. The device isolates a segment of the aortic wall from the flowing column of blood using a balloon mounted on a metal alloy strut assembly. The strut assembly expands radially from a collapsed, low-profile configuration when uncovered by a constraining outer sheath. Aortic blood flow is allowed through the flow passage thus contained by the strut assembly within the center of the balloon. The balloon is inflated to contact the aortic wall. The balloon contains a pocket shaped to allow aortic fenestration. The balloon contains radiopaque markers to facilitate orientation and positioning of the pocket within the aorta. Other embodiments using spaced balloons are also disclosed.
    • 描述了用于允许开启主动脉壁同时保持远端灌注并防止外部出血的医疗装置和方法。 该装置使用安装在金属合金支柱组件上的球囊将主动脉壁的一段与流动的血液柱隔离。 当被约束外护套覆盖时,支柱组件从折叠的低轮廓构造径向膨胀。 允许主动脉血流通过由球囊中心内的支柱组件包含的流动通道。 气囊膨胀以接触主动脉壁。 气囊包含一个口袋形状以允许主动脉开窗。 气球包含不透射线的标记,以便于主动脉内袋的取向和定位。 还公开了使用间隔球囊的其它实施例。
