Abstract:
1. A bio-implantable energy capture and storage assembly, for implantation into tissue comprising: i. an acoustic energy transmitter and an acoustic energy receiver, said acoustic energy receiver also functioning as an energy converter for converting acoustic energy to electrical energy at a rate of at least 5 Watts; ii. an electrical energy storage device electrically connected to said energy converter, wherein said acoustic energy receiver-converter is contained within the device for implantation in said tissue; iii. an acoustic energy transmitter external to the body and separate from said implant, and wherein the transmitter comprises at least one transducer comprising a 2-dimensional array of elements arranged in a substantially regular 2-dimensional geometric shape on a support; and iv. a cooling system including a circulating coolant and heat exchanger for removing heat from the energy transmitter, tissue, and implant at a rate of at least 3 Watts; wherein said transmitter operates at a frequency in the range of 0.75 to 1.5 MHz.
