1. An implantable medical device comprising:

  • operational circuitry, wherein the operational circuitry includes at least one of a therapy circuit and a sensor circuit;

    a power source configured to deliver energy to the operational circuitry;

    a deactivation element configured to at least partially disable the operational circuitry of the implantable medical device by interrupting delivery of energy from the power source to the operational circuitry;

    a power manager configured to detect an end-of-life condition of the power source and, in response to detecting the end-of-life condition, to cause the deactivation element to at least partially disable the operational circuitry of the implantable medical device, wherein the power manager is configured to detect the end-of-life condition by detecting an abnormality in a functionality of at least a portion of the operational circuitry; and

    a communications component, wherein the power source comprises a first energy storage component and a second energy storage component, and wherein the first energy storage component is configured to store energy for powering at least the therapy circuit and the communications component, and wherein the second energy storage component is configured to store energy for powering the deactivation element.
