Miniaturized Wireless Ultrasound Energy Transfer System for Powering a Bio-Implantable Medical Device

A system for providing energy to a bio-implantable medical device, the system comprising:

• an acoustic energy delivery device configured to be secured to a patient's skin and apposed superficial tissue, the acoustic energy delivery device comprising:
• a delivery device housing;
• a multi-dimensional array of transmitting electroacoustical transducers disposed on or in the delivery device housing, the multi-dimensional array of transmitting electroacoustical transducers arranged in a substantially regular two-dimensional geometric shape;
• a signal generator and power output board disposed in the delivery device housing, the signal generator in electrical communication with the multi-dimensional array of transmitting electroacoustical transducers;
• a microprocessor-based controller disposed in the delivery device housing, the microprocessor-based controller in electrical communication with the signal generator and the multi-dimensional array of transmitting electroacoustical transducers;
• and
• a battery disposed in the delivery device housing, the battery electrically coupled to the multi-dimensional array of transmitting electroacoustical transducers, the signal generator and power output board, and the microprocessor-based controller;
• a bio-implantable electroacoustical energy converter configured to be electrically coupled to the bio-implantable medical device, the bio-implantable electroacoustical energy converter coupled to the patient's skin tissue comprising:
• a converter device housing;
• one or more receiving electroacoustical transducers disposed on or in the converter device housing, the one or more receiving electroacoustical transducers configured to convert acoustic energy received from the acoustic energy delivery device into converted electrical energy;
• and
• an energy rectification and storage device disposed in the converter device housing, the energy storage device in electrical communication with the one or more receiving electroacoustical transducers to store at least a portion of the converted electrical energy.
