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, byenforcing operational-mode-specific communication protocols whereby inter-device communication between the implantable medical device and another implantable medical device is such that level of powerdraw 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.

Description

technical field [0001] The present disclosure relates to implantable medical devices, and in particular to systems including at least one rechargeable implantable medical device and at least one non-rechargeable implantable medical device. Background technique [0002] Leadless pacing devices are examples of implantable medical devices and may confer advantages over traditional pacing devices, as the elimination of leads may translate to less complexity and thus improved patient outcomes. However, there are a number of significant technical challenges when introducing leadless pacing devices into the system as companion devices. For example, communication between medical devices may be desired to coordinate therapy and / or sensing functions, such as to enable multi-chamber pacing modes. However, such communications can consume electrical resources of the leadless pacing device. Contents of the invention [0003] There are a number of significant technical challenges when ...
