(57) ABSTRACT
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 to 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.
