Abstract:
1. An acoustic energy delivery system for delivering acoustic energy to an implantable medical device (“IMD”) located within a patient's body, the system comprising: an IMD including a power source and at least one ultrasonic transducer; and an energy delivery device configured to deliver acoustic energy for recharging the power source of the IMD, the energy delivery device including a controller and an array of ultrasonic elements electrically coupled to the controller and configured to transmit an acoustic field through the body to the IMD; wherein the controller is configured to selectively control one or more ultrasonic elements of the array for manipulating the acoustic field within the body based at least in part on one or more acoustic feedback signals transmitted by the at least one ultrasonic transducer of the IMD and received on the array of ultrasonic elements.
