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.

Abstract
A therapeutic fluid delivery device that includes at least one controllable valve is generally described. In one example, an implantable therapeutic fluid delivery system includes a first fluid pathway configured to convey a first therapeutic fluid and a second fluid pathway configured to convey a second therapeutic fluid, the second fluid pathway being separate from the first fluid pathway. The therapeutic fluid delivery system includes a valve connected to the first fluid pathway and the second fluid pathway, and a processor configured to control actuation of the valve to open and close the first fluid pathway and to open and close the second fluid pathway.
