Patent Images
1. A system for locating an acoustic receiver-stimulator, comprising:
- an implantable acoustic controller-transmitter comprising an array of acoustic transducers configured to transmit focused acoustic energy to a tissue location;
at least one implantable acoustic receiver-stimulator adapted to receive the focused acoustic energy and convert the focused acoustic energy into electrical energy;
wherein the receiver-stimulator further comprises two electrodes configured to be in electrical connection with tissue and to deliver the electrical energy to the tissue;
wherein the controller-transmitter is configured to detect the delivered electrical energy to determine whether the receiver-stimulator is present at the tissue location; and
wherein the controller-transmitter is further configured to adjust the transducer array to transmit focused acoustic energy to the tissue location associated with the detected electrical energy.

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.
