First Claim
Patent Images
1. 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 for transmitting an inductive or RF signal into the patient'"'"'s body;
an implantable medical device including an energy translator circuit adapted to convert the inductive or RF signal received from the interrogator device into an acoustic signal for driving an acoustic 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.

23. A medical device implantable within the body of a patient, comprising:
-
an energy translator circuit configured to convert inductive or RF signals received from one or more devices located outside of the patient'"'"'s body into an electrical signal, the energy translator circuit including; an inductor coil magnetically coupled to an inductor coil located externally of the patient'"'"'s body; and an acoustic transducer operatively coupled to the inductor coil of the energy translator circuit and configured to produce an acoustic field based on the electrical signal.
