Abstract
Techniques for minimizing rate of depletion of a non-rechargeable power source, to extend the operational lifetime of an implantable medical device that includes the non-rechargeable power source, by enforcing operational-mode-specific communication protocols whereby inter-device communication between the implantable medical device and another implantable medical device is such that level of power draw from the non-rechargeable power source by the implantable medical device is less than level of power draw from the rechargeable power source by the another implantable medical device for the implantable medical devices to engage in communication with each other.
Claims20
A medical device system comprising:
- a first implantable medical device comprising a leadless intracardiac pacing device configured to be positioned entirely within a heart chamber of a patient;
- a second implantable medical device operable together with the first implantable medical device as a multi-chamber pacing system;
- a memory configured to store a set of operational modes including a synchronized mode in which the first implantable medical device and the second implantable medical device operate in synchronization, and a loss of synchronization mode associated with a loss of synchronization communication protocol;
- and
- processing circuitry in communication with the memory, wherein the processing circuitry is configured to:
- determine a loss of synchronization between the first implantable medical device and the second implantable medical device;
- implement the loss of synchronization communication protocol;
- and
- via implementation of the loss of synchronization communication protocol, re-establish synchronization between the first implantable medical device and the second implantable medical device.
A method comprising:
- determining, by processing circuitry in communication with a memory, a loss of synchronization between a first implantable medical device and a second implantable medical device,
- wherein the first implantable medical device comprises a leadless intracardiac pacing device configured to be positioned entirely within a heart chamber of a patient,
- wherein the second implantable medical device is operable together with the first implantable medical device as a multi-chamber pacing system,
- wherein the memory is configured to store a set of operational modes including a synchronized mode in which the first implantable medical device and the second implantable medical device operate in synchronization, and a loss of synchronization mode associated with a loss of synchronization communication protocol;
- implementing, by the processing circuitry, the loss of synchronization communication protocol;
- and
- via implementation of the loss of synchronization communication protocol, re-establishing, by the processing circuitry, synchronization between the first implantable medical device and the second implantable medical device.
A non-transitory computer-readable storage medium comprising program instructions that, when executed by processing circuitry in communication with a memory of a medical device system comprising a first implantable medical device and a second implantable medical device operable together with the first implantable medical device as a multi-chamber pacing system, cause the processing circuitry to:
- determine a loss of synchronization between a first implantable medical device and a second implantable medical device,
- wherein the first implantable medical device comprises a leadless intracardiac pacing device configured to be positioned entirely within a heart chamber of a patient, and
- wherein the memory is configured to store a set of operational modes including a synchronized mode in which the first implantable medical device and the second implantable medical device operate in synchronization, and a loss of synchronization mode associated with a loss of synchronization communication protocol;
- implement the loss of synchronization communication protocol;
- and
- via implementation of the loss of synchronization communication protocol, re-establish synchronization between the first implantable medical device and the second implantable medical device.
