IMPLANTABLE MEDICAL DEVICE FOR DETECTING ACOUSTIC COMMUNICATION SIGNALS AND ACOUSTIC BIOMETRIC SIGNALS

In some examples, a medical device system includes an implantable medical device (IMD) configured to be implanted underneath a skin of a patient, the IMD comprising: acoustic receiving circuitry configured to: receive one or more acoustic communication signals; and receive one or more acoustic biometric signals from the patient. The medical device system includes communication circuitry configured for wireless communication according to a communication protocol. Additionally, the medical device system includes processing circuitry configured to: receive, via the acoustic receiving circuitry, a sequence of acoustic communication signals that are separate from the one or more acoustic biometric signals; decode the sequence of acoustic communication signals to identify one or more requested actions; and control the IMD to perform the one or more requested actions.
