    • A catheter device for transferring fluid material to or from one or more selected-length segment of a vessel. The device includes first and second catheters, each having a tube with distal and proximal ends, an inflatable balloon carried on the tube, adjacent the distal tube end, and a fluid conduit for supplying the balloon, with such operatively positioned in the vessel. A central region of the second-catheter tube is axially shiftable within the first-catheter tube, allowing the balloons to be placed at desired relative positions in the vessel. Fluid is injected into the region between the two balloons through a fluid passageway formed in a channel in the first-catheter tube.
    • 一种导管装置,用于将流体材料输送到或从容器的一个或多个选定长度的段进行传送。 该装置包括第一和第二导管,每个导管具有带有远端和近端的管,邻近远端管端承载在管上的可膨胀气囊,以及用于供应气囊的流体导管,可操作地定位在容器中。 第二导管管的中心区域在第一导管管内可轴向移动,允许气囊放置在容器中期望的相对位置。 流体通过形成在第一导管中的通道中的流体通道注入到两个气囊之间的区域中。
