Abstract
An implantable medical device includes operational circuitry and a power source configured to deliver energy to the operational circuitry. The operational circuitry includes, for example, a therapy circuit. The implantable medical device also includes a deactivation element configured to disable the therapy circuit. The implantable medical device also includes 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 disable the therapy circuit.
Claims20
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;
- and
- 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.
A leadless cardiac pacing seed comprising:
- a therapy circuit;
- a power source configured to deliver energy to the therapy circuit;
- and
- a deactivation element configured to disable the therapy circuit by interrupting delivery of energy from the power source to the therapy circuit;
- a power manager configured to detect an end-of-life condition of the seed and, in response to detecting the end-of-life condition, cause the deactivation element to disable the therapy circuit.
A cardiac pacing system comprising:
- an implantable leadless cardiac pacing seed configured to deliver electrostimulation therapy to a patient, the implantable leadless cardiac pacing seed comprising:
- a therapy circuit;
- a communications component configured to receive a deactivation signal from an external device;
- a power source configured to deliver energy to the therapy circuit and the communications component;
- and
- a power manager configured to detect an end-of-life condition of at least one of the power source and the therapy circuit and, in response to detecting the end-of-life condition, place the implantable leadless cardiac pacing seed in an end-of-life state;
- and
- a deactivation element configured to interrupt delivery of energy from the power source to the therapy circuit so as to disable at least the therapy circuit in response to the deactivation signal being received by the communications component;
- and
- an external device configured to provide the deactivation signal to the communications component.
