Patent Images
1. An implantable medical device, comprising:
- an acoustic element;
a control module coupled to the acoustic element for controlling the function of the acoustic element;
an acoustic sensing module coupled to the control module for receiving acoustical signals from the acoustic element via the control module; and
a patient alert driver module coupled to the control module and generating a patient alert drive signal for activating the acoustic element via the control module to emit a patient alert signal;
the control module configured to detect the patient alert drive signal and comprising an isolation circuit for isolating the acoustic sensing module from the acoustic element in response to the patient alert drive signal.

Abstract
An implantable medical device having an acoustic element includes a control module coupled to the acoustic element, an acoustic sensing module coupled to the control module, and a patient alert driver module coupled to the control circuit. The patient alert driver module generates a patient alert drive signal for activating the acoustic element to emit a patient alert signal. The control module includes an isolation circuit for isolating the acoustic sensing module from the acoustic element in response to the patient alert drive signal.
