Abstract:
1. A device for transferring fluids between an internal structure in a living body and an exterior thereof, comprising: a housing including a pressure activated lumen and a power injection lumen, wherein the power injection lumen extends to a distal port configured for connection to a fluid conduit extending to a target structure within the body; a pressure activated valve configured to fluidly connect the pressure activated lumen to the power injection lumen and controlling fluid flow therebetween, 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; and 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.
