Patent ID: 8301262

Claim:
A system for communicating with or powering one or more remote devices located within the body of a patient, the system comprising: an interrogator device located outside of the patient's body, the interrogator device including an energy source and an inductor for transmitting an inductive or RF signal into the patient's body; an implantable medical device including an energy translator circuit, the energy translator circuit comprising an LC resonance loop formed by the inductance of an inductor in wireless communication with the inductor of the interrogator device and the capacitance of an ultrasonic transducer, wherein the LC resonance loop has an electrical resonance mode adapted to convert the inductive or RF signal received from the interrogator device into an acoustic signal for driving the ultrasonic transducer at or near a resonance frequency or natural harmonic frequency of the transducer; and one or more remote devices adapted to sense a physiologic parameter within the body, at least one of the remote devices including an acoustic transducer adapted to receive an acoustic field transmitted by the implantable medical device.
