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 anmotor at a controllable rate.

[ I claim:] [1.]1. An implantable drug delivery device, comprising:a dispensing chamber having an upper surface, said dispensing chamber comprising:a dispensing passage formed along an interior surface of said dispensing chamber and having an intake end and an outlet end; andan actuator for applying to said dispensing passage a rotational compressive force moving in a direction from said intake end towards said outlet end; anda reservoir housing provided adjacent said upper surface of said dispensing chamber and having a reservoir provided therein, said reservoir being in fluid communication with said intake end of said dispensing passage; andmeans for filling said reservoir, wherein said means for filling is provided in relation to a surface of said reservoir housing which is not adjacent to said upper surface of said dispensing chamber.
