A fluid delivery apparatus for infusing medicinal fluids into a patient which is of a compact, low profile, laminate construction. The apparatus embodies a novel light activated expanding polymer material which uniquely functions as an internal energy source for expelling the medicinal fluids from the device. The light polymer mass is activated by a novel light source in a manner to controllably expel fluid from the device. Further, the light actuated polymer can be specifically tailored to provide precise, predictable protocol delivery of the medicinal agent stored within the reservoir of the device. In one form of the invention, the fluid delivery apparatus is implantable within the patient's body.
