  • Implantable electrodes with remote power delivery for treating sleep apnea, and associated systems and methods
    Patent number: 11986658
    Abstract: Implantable electrodes with power delivery wearable for treating sleep apnea, and associated systems and methods are disclosed herein. A representative system includes non-implantable signal generator worn by the patient and having an antenna that directs a mid-field RF power signal to an implanted electrode. The implanted electrode in turn directs a lower frequency signal to a neural target, for example, the patient's hypoglossal nerve. Representative signal generators can have the form of a mouthpiece, a collar or other wearable, and/or a skin-mounted patch.
