Abstract

Techniques are disclosed for using a rate of wireless telemetry of an implantable medical device (IMD) to estimate a remaining longevity of a power source of the IMD. For example, the IMD sets a timer indicative of a remaining power capacity of the power source until a recommended replacement time (RRT) threshold. The IMD determines a power consumption of the IMD due to telemetry and updates, based on the power consumption of the IMD due to telemetry, the timer indicative of the remaining power capacity of the power source. The IMD determines, based on expiration of the timer indicative of the remaining power capacity of the power source, that the power source has reached the RRT threshold. In some examples, the IMD may output, to an external device and for display to a user, an indication that the power source has reached the RRT threshold.
