Acoustic Telemetry System for Communication with an Implantable Medical Device
First Claim
1. An implantable medical device comprising:
- a transducer that receives an acoustic carrier signal incident on the transducer; and
a control unit that modulates a reflected portion of the acoustic carrier signal with data to be transmitted from the implantable medical device.

Abstract
A telemetry module of an IMD operating in accordance with the techniques of this disclosure receives an unmodulated acoustic carrier signal from another device and modulates a reflected portion of the acoustic carrier signal with data for transmission to the other device. In one instance, the telemetry module may modulate the reflected portion of the carrier signal with data by selectively adjusting a reflectance of the transducer of the IMD. For example, the IMD may set the reflectance to be high or low depending on the information, e.g., digital 1 or 0, to be transmitted. The reflectance may be set high by leaving the electrical terminals of the transducer open such that there is no electrical dissipation and the reflectance may be set low by shorting the electrical terminals of the transducer such that energy is dissipated.
