Abstract
An implantable fluid delivery apparatus for infusing medicinal fluids into a patient that includes a novel basal delivery system that includes a heat responsive polymer gel material which upon being heated by heater foil uniquely functions as an internal energy source for expelling basal doses of medicinal fluids from the device. The apparatus also includes a bolus delivery system that includes a magnetically responsive polymer gel which, upon being stimulated by an electro-magnet will delivery precise bolus doses of medicinal fluids to the patient.
