AI Technical Summary

Benefits of technology

This system enables efficient and adaptive energy delivery to implants, improving treatment efficacy by aligning power transmission with the subject's needs, extending battery life, and maintaining reliable power over larger distances, thus enhancing the management of neurological disorders.

Problems solved by technology

Many neurological disorders reduce or eliminate voluntary recruitment of muscles, which may result in loss of ability to perform motor tasks or to maintain systems that depend on muscle activity for their function.

Embodiment Construction

[0175]Reference is made to FIGS. 1A-B and 2, which are schematic illustrations of a system 20, and use thereof, for treating a condition of a subject 10, in accordance with some applications of the invention. System 20 comprises an implant 30, a first extracorporeal controller 40, and a second extracorporeal controller 50.

[0176]Implant 30 comprises one or more tissue-contacting electrodes 32, an antenna 34 configured to receive wireless power, and circuitry 35 configured to be powered by the wireless power received by antenna 34, and to responsively drive the electrodes to apply a treatment current to tissue that is in contact with the electrodes (e.g., circuitry 35 defines and / or comprises a control unit 36). Typically, implant 30 does not comprise a battery or other non-transient power storage element, advantageously reducing the size of the implant. (However implant 30 may comprise a capacitor.) The current is configured, and the implant is positioned, to treat the condition of t...

Abstract

An implant includes tissue-contacting electrodes; at least one implant antenna configured to receive wireless power; and implant circuitry configured to use the received wireless power to drive the one or more electrodes to apply a current. A hand-held controller includes: (i) one or more controller antennas, configured to transmit the wireless power, and to communicate with a consumer device; (ii) a battery configured to store battery power; and (iii) controller circuitry configured to: (a) use the battery power to drive at least one of the controller antennas to transmit the wireless power, (b) identify a position of the controller with respect to the implant, and (c) drive at least one of the controller antennas to transmit juxtaposition information to the consumer device about the position of the controller with respect to the implant.
