    • Apparatus and methods for delivering prosthetic segments to a body lumen include an elongated flexible member having both proximal and distal ends along with a plurality of prosthetic segments releasably arranged axially along the elongated flexible member near the distal end. Additionally, the apparatus has a sheath slidably disposed over at least a portion of the prosthetic segments and an outer shaft slidably disposed over at least a portion of the sheath. A separator is disposed on the outer shaft and is biased into engagement with at least one prosthetic segment so that the outer shaft may be retracted to separate a proximal group of prosthetic segments from a distal group of prosthetic segments which are to be deployed into the body lumen. The sheath is positionable between the separator and the prosthetic segments to selectively disengage the separator from the prosthetic segments.
    • 用于将假肢段递送到体腔的装置和方法包括细长的柔性构件,其具有近端和远端以及沿着远端的细长柔性构件沿轴向可释放地布置的多个假体段。 此外,该装置具有可滑动地设置在假肢段的至少一部分上的护套和可滑动地设置在护套的至少一部分上的外轴。 分离器设置在外轴上并且被偏压成与至少一个假肢段接合,使得外轴可以缩回以将近端组的假肢段与要部署到身体中的假肢段的远侧组分离 流明。 护套可定位在分离器和假肢段之间以选择性地使分离器与假肢段脱离。

    • An apparatus for providing a seamless supply of fluid from a first exhaustible fluid supply and a second fluid supply is described, said apparatus comprising: a switching vessel having at least one first inlet for receiving fluid from the first exhaustible fluid supply and at least one second inlet for receiving fluid from the second fluid supply and at least one fluid outlet; and a regulating mechanism arranged to provide fluid from said first exhaustible supply for output at said at least one fluid outlet whilst said first exhaustible supply is not exhausted, and fluid from said second fluid supply when said first exhaustible fluid supply becomes exhausted; the apparatus being further provided with means arranged such that fluid is retained substantially within said first exhaustible fluid supply and said second fluid supply when fluid is not required from said at least one outlet. A helical float valve arrangement for use with such an apparatus is also described.
    • 描述了一种用于提供来自第一可排出流体供应源和第二流体供应源的流体的无缝供应的设备,所述设备包括:切换容器,其具有至少一个用于从第一可排出流体供应源接收流体的第一入口和至少一个第二 用于接收来自第二流体供应源和至少一个流体出口的流体的入口; 以及调节机构,其布置成当所述第一可消耗供应源不被排出时,提供来自所述第一可排出供应源的流体,以在所述至少一个流体出口处输出;以及当所述第一可排出流体供应源耗尽时来自所述第二流体供应源的流体; 该装置还设置有这样的装置,使得当不需要所述至少一个出口的流体时,流体基本保持在所述第一可排出流体供应源和所述第二流体供应源内。 还描述了与这种装置一起使用的螺旋浮阀装置。
