Abstract
An infusion assembly for delivering therapeutic fluid to plural body sites is provided. The assembly includes a positive displacement pump that discharges the therapeutic fluid. The assembly also includes a flow regulator valve including a valve housing that defines a pressure chamber, an inlet bore that opens into the pressure chamber, and first and second outlet passageways. The first and second outlet passageways extend, respectively, from separate first and second outlet openings to a first catheter and a second catheter through which the therapeutic fluid is directed to the body sites. A controller cyclically regulates the operation of the pump so that, in a first phase of each cycle, the pump is actuated so as to cause a fluid pulse to be presented through the inlet bore of the valve housing to the diaphragm and in a second phase of each cycle, the pump is not actuated.
