An implantable medical device includes operational circuitry, such as a therapy circuit. The implantable medical device also includes a power source configured to deliver energy to the operational circuitry, and a deactivation element configured to disable the therapy circuit. A power manager is configured to detect an end-of-life condition of the power source and, in response to detecting the end-of-life condition, cause the deactivation element to reversibly disable the therapy circuit.

1. An implantable medical device comprising: operational circuitry, wherein the operational circuitry comprises at least one of a therapy circuit and a sensor circuit;a communications module;a power source configured to deliver energy to the operational circuitry;a deactivation element configured to at least partially disable the operational circuitry by interrupting delivery of energy from the power source to the operational circuitry;a power manager configured to detect, based on a behavior of at least the communications module, an end-of-life condition of the power source and, in response to detecting the end-of-life condition, cause the deactivation element to at least partially reversibly disable the operational circuitry; anda controller configured to store, in a memory component and in response to the power manager detecting the end-of-life condition, an indication of an end-of-life state of the implantable medical device. 2. The implantable medical device of claim 1, wherein the implantable medical device comprises a leadless cardiac pacing seed. 3. The implantable medical device of claim 1, wherein the operational circuitry comprises the therapy circuit. 4. The implantable medical device of claim 3, wherein the deactivation element is configured to prevent energy from being delivered to the therapy circuit. 5. The implantable medical device of claim 1, wherein the memory component comprises an active storage element. 6. The implantable medical device of claim 5, wherein the power manager is configured to allow energy to be delivered to the memory component during the end-of-life state. 7. The implantable medical device of claim 1, wherein the memory component comprises a non-volatile memory element. 8. The implantable medical device of claim 7, wherein the memory component is further configured to store a plurality of operational parameters during the end-of-life state. 9. The implantable medical device of claim 8, wherein the power source comprises a rechargeable battery. 10. The implantable medical device of claim 9, wherein the controller is configured to access the plurality of operational parameters in response to receiving an activation signal. 11. The implantable medical device of claim 10, wherein the controller is configured to restore the device to its pre-end-of-life state using the operational parameters. 12. A leadless cardiac pacing seed comprising: a therapy circuit;a communications module;a power source configured to deliver energy to the therapy circuit and the communications module;a deactivation element configured to disable at least one of the therapy circuit and the communications module by reversibly interrupting delivery of energy from the power source to the therapy circuit or the communications module;a power manager configured to detect, based on a behavior of at least the communications module, an end-of-life condition of the seed and, in response to detecting the end-of-life condition, cause the deactivation element to reversibly disable at least one of the therapy circuit and the communications module; anda controller configured to store, in a memory component and in response to the power manager detecting the end-of-life condition, an indication of an end-of-life state of the implantable medical device. 13. The leadless cardiac pacing seed of claim 12, wherein the memory component comprises an active storage element. 14. The leadless cardiac pacing seed of claim 13, wherein the power manager is configured to allow energy to be delivered to the memory component during the end-of-life state. 15. The leadless cardiac pacing seed of claim 12, wherein the memory component comprises a non-volatile memory element. 16. The leadless cardiac pacing seed of claim 15, wherein the memory component is further configured to store a plurality of operational parameters during the end-of-life state, and wherein the controller is configured to access the plurality of operational parameters in response to receiving an activation signal. 17. The implantable medical device of claim 16, wherein the controller is configured to restore the device to its pre-end-of-life state using the operational parameters.
