1. An implantable device for delivering electrical stimulation pulses to a patient'"'"'s body, comprising:

  • a housing;

    a pair of electrodes carried by the housing;

    a piezoelectric element that is enclosed by the housing and produces voltage signals in response to receiving ultrasound energy transmitted through the patient'"'"'s body; and

    a circuit coupled to the piezoelectric element and configured to pass at least a portion of the voltage signals produced by the piezoelectric element to the pair of electrodes for delivering an electrical stimulation pulse to the patient'"'"'s body, the circuit comprising a rate limiter configured to filter a voltage signal produced by the piezoelectric element that occurs at an interval less than a maximum pulse rate interval after a preceding voltage signal has been passed to the pair of electrodes.
