    • A device for transferring fluids between an internal structure in a living body and an exterior thereof, comprises a housing including a pressure activated lumen extending to a distal end opening to a power injection lumen that extends to a distal port configured for connection t a fluid conduit extending to a target structure within the body and a pressure activated valve extending across the pressure activated lumen and controlling fluid flow therethrough, the pressure activated valve opening to permit fluid flow therethrough into the power injection lumen when a fluid pressure differential thereacross is at least a first predetermined threshold level and remaining sealed when the fluid pressure differential thereacross is less than the first threshold level in combination with a proximal port coupled to the housing for movement between a first position in which a proximal end of the power injection lumen opens to the proximal port and a second position in which a proximal end of the pressure activated lumen opens to the proximal port.
    • 一种用于在活体内部结构和其外部之间传送流体的装置,包括壳体,该壳体包括延伸到动力注射腔的远端开口的压力活化腔,其延伸至构造成连接的远端口, 到主体内的目标结构,以及压力激活的阀,其延伸穿过压力激活的腔并且控制通过其中的流体流动,压力激活的阀开口,以允许流体流过动力注射腔,当其中的流体压力差异为至少第一 预定的阈值水平并且当其相交的流体压差小于第一阈值水平时保持密封,其结合耦合到壳体的近端口,用于在第一位置和第二位置之间移动,在第一位置中,动力注射腔的近端与近端口 以及第二位置,其中的近端 压力激活的管腔通向近端口。
