Abstract:
1. A system for acoustically powering a satellite pacing device located within a patient's body, the system comprising: a satellite pacing device configured to deliver therapy to the body, the satellite pacing device including at least one ultrasonic transducer configured for converting acoustic energy into electrical energy for powering one or more components of the satellite pacing device; and an energy delivery device configured to transmit an acoustic field through the body to the satellite pacing device, the energy delivery device including an array of ultrasonic transducer elements coupled to a controller, the controller configured to selectively control one or more of the ultrasonic transducer elements of the array for focusing the acoustic field within the body based at least in part on one or more response signals received from the satellite pacing device; wherein the one or more response signals includes an acoustic feedback signal transmitted by the at least one ultrasonic transducer and received on the array of ultrasonic transducer elements, the acoustic feedback signal including a measure of an acoustic signal amplitude of an acoustic signal transmitted by each individual ultrasonic transducer element of the array received by the satellite pacing device.
