Optimizing energy transmission in a leadless tissue stimulation system
First Claim
Patent Images
1. A system for transferring acoustic energy, comprising:
- an implantable acoustic controller-transmitter comprising an acoustic transducer array configured to transmit acoustic energy into tissue;
an implantable acoustic receiver-converter adapted to receive the acoustic energy and convert the acoustic energy to electrical energy, wherein the controller-transmitter is configured to transmit an acoustic locator signal and the receiver-converter is configured to generate an electrical location signal in response to the locator signal, wherein the controller-transmitter is configured to detect the location signal and to direct a focused acoustic beam towards the receiver-converter by adjusting the transducer array to transmit focused acoustic energy to a region of the tissue associated with the detected electrical location signal using one or more characteristics of said location signal.

Abstract
Method and systems for optimizing acoustic energy transmission in implantable devices are disclosed. Transducer elements transmit acoustic locator signals towards a receiver assembly, and the receiver responds with a location signal. The location signal can reveal information related to the location of the receiver and the efficiency of the transmitted acoustic beam received by the receiver. This information enables the transmitter to target the receiver and optimize the acoustic energy transfer between the transmitter and the receiver. The energy can be used for therapeutic purposes, for example, stimulating tissue or for diagnostic purposes.
