Abstract: Charging a battery of an implanted device involves positioning an external charging coil proximal to a charging locale. An implant recipient and the implanted device are expected to occupy the charging locale from time to time. The charging coil has a coil area which is significantly larger than a coil area of an implanted coil, and is configured to produce an electromagnetic field throughout the charging locale. When an implant recipient is within the charging locale, the external charging coil is driven with a signal which transmits electromagnetic power from the charging coil to the implanted coil.

Abstract: The present invention generally relates to a control system for a rotary blood pump adapted to move blood in a patient. The control system comprises a means for measuring and varying the speed of the pump and a means for measuring the pulsatility index of a patient, and the control system is adapted to maintain the pulsatility index at or near a predetermined value by varying the speed of the pump.
