An implantable drug delivery pump includes a reservoir, a dispensing chamber adjacent to the reservoir, a dispensing passage provided along an interior surface of the dispensing chamber, and an actuator for applying a moving compressive force onto the dispensing passage. The pump is subcutaneously implantable in a patient, and a drug is injected into the reservoir through a septum provided on a housing for the reservoir. As the compressive force applied by the actuator moves along the dispensing passage, the drug preparation is simultaneously pushed out of the dispensing passage into a catheter for delivery to the desired site, and additional drug preparation is drawn into the dispensing passage from the reservoir. The actuator includes a rotating arm driven by an motor at a controllable rate.
