Abstract

A device and system for remotely interrogating a diagnostic implant device utilizes acoustic energy to power and/or interrogate the device. Acoustic energy is utilized to excite the device from outside the body of a patient. By analyzing the response of the device to such excitation, it is possible to ascertain the condition of the device. Additionally, acoustic energy may be used to provide operating power to the device.
