  • ACCELEROMETER FEEDBACK CONTROL LOOP FOR PATIENT ALERT
    Publication number: 20120194341
    Abstract: A system and associated method for alerting a patient of a condition detected by an implanted medical device by delivering an alert signal to cause a motion within the patient's body in response to detecting the condition. An accelerometer signal is measured during the alert signal delivery. Accelerometer signal measurements are compared to a threshold. A parameter controlling the alert signal is adjusted to maintain the accelerometer signal within a range of the threshold.

  • Reversible implantable acoustic sensor
    Patent number: 8078285
    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.
