1. An implantable therapeutic fluid delivery system comprising:

  • a first fluid pathway configured to convey a first therapeutic fluid;

    a second fluid pathway configured to convey a second therapeutic fluid, the second fluid pathway being separate from the first fluid pathway;

    a valve connected to the first fluid pathway and the second fluid pathway;

    a pump, the first fluid pathway being fluidly connected to the pump;

    a reservoir, the first fluid pathway being fluidly connected to the reservoir;

    an inlet port configured to receive the first therapeutic fluid and the second therapeutic fluid, wherein the valve is interposed between the inlet port and the reservoir along the first fluid flow pathway;

    a processor configured to actuate the valve to selectively open and close the first fluid pathway to control access to the reservoir, and to selectively open and close the second fluid pathway;

    a housing configured to be implanted in a patient, wherein the first fluid pathway, the second fluid pathway, the valve, and the reservoir are housed within the housing; and

    a catheter connection port configured to connect to a catheter;

    wherein the first fluid pathway extends from the inlet port to the catheter connection port and is fluidly connected to the catheter connection port, and the reservoir is interposed between the valve and the catheter connection port along the first fluid pathway, andwherein the second fluid pathway extends from the inlet port to the catheter connection port and is directly fluidly connected to the catheter connection port without passing through any reservoir or any pump, and the valve is interposed between the inlet port and the catheter connection port along the second fluid pathway;

    wherein the system is configured to deliver;

    the first therapeutic fluid, via the first fluid pathway, from the inlet port, through the valve, through the reservoir, through the pump, and out the catheter connection port; and

    the second therapeutic fluid, via the second fluid pathway, from the inlet port, through the valve, and out the catheter connection port.
