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.
