ABSTRACT:
An implantable drug delivery device includes a pump motor that is driven by electrical energy from a storage capacitor. At the end of each pump delivery cycle, electrical energy stored in the pump motor is recovered and returned to the storage capacitor, so that it can be used in subsequent delivery cycles.
