    摘要： An evacuation sheath assembly and method of reducing or removing a blockage within a vessel without permitting embolization of particulate matter is provided. The evacuation sheath assembly includes a first elongate tubular member, having proximal and distal ends and a main lumen configured to be placed in fluid communication with a blood vessel. An expandable member is provided on a distal portion of the tubular member and is configured to form a seal with the blood vessel. The evacuation assembly further includes a second elongate tubular member having proximal and distal ends and an inflation lumen configured to be placed in fluid communication with the expandable member and a gas inflator. The gas inflator includes a high pressure gas source and a mechanism for regulating the pressure of the gas delivered by the gas inflator. The gas inflator is configured to be placed in fluid communication with the proximal end of the inflation lumen in order to provide a regulated pressure gas source for inflating the expandable member. A method of treatment of a blood vessel using the evacuation sheath assembly includes advancing the evacuation sheath assembly into the blood vessel through a guide catheter. The expandable member is inflated to provide form a seal between the blood vessel and the guide catheter and a vacuum is applied to the main lumen of the first elongate tubular member to cause retrograde blood flow and carry fluid into the main lumen of the evacuation sheath assembly.

    摘要翻译： 提供疏散护套组件以及在不允许颗粒物质栓塞的情况下减少或去除容器内的堵塞的方法。 抽真空组件包括第一细长管状构件，其具有近端和远端以及构造成与血管流体连通的主腔。 可膨胀构件设置在管状构件的远侧部分上并构造成与血管形成密封。 排气组件还包括具有近端和远端的第二细长管状构件和构造成与膨胀构件和气体充气器流体连通的膨胀腔。 气体充气机包括高压气体源和用于调节由气体充气机输送的气体的压力的机构。 气体充气器被配置成与膨胀腔的近端流体连通，以便提供用于使可膨胀构件膨胀的调节压力气体源。 使用排气鞘组件治疗血管的方法包括通过引导导管将排空鞘组件推进到血管中。 可膨胀构件被膨胀以在血管和引导导管之间形成密封，并且将真空施加到第一细长管状构件的主腔，以引起逆行血流并将流体携带到排泄鞘组件的主腔内 。
