1. An infusion device configured for implantation in a patient's body, the infusion device comprising:
a housing; a pressure source associated with the housing; a reservoir in the housing including at least first and second reservoir compartments, the first and second reservoir compartments being positioned relative to one another and relative to the pressure source such that the pressure source acts directly on the first reservoir and the first reservoir separates the pressure source from the second reservoir; a pressure transmissive interior partition between the first and second reservoir compartments configured to equalize pressure within the first and second reservoir compartments; a first fluid transfer device operably connected to the first reservoir compartment and to a first fluid outlet; a second fluid transfer device operably connected to the second reservoir compartment and to a second fluid outlet; and a controller that controls at least one of the first and second fluid transfer devices.
