Techniques for switching an implantable medical device (IMD) from a first mode to a second mode in relation to signals obtained from internal sensors are described. The internal sensors may include a temperature sensor and a biosensor. In some examples, processing circuitry of the IMD may make a first preliminary determination that the IMD is implanted based on a first signal from the temperature sensor. In response to the first preliminary determination being that the IMD is implanted, the processing circuitry may make a second preliminary determination that the IMD is implanted based on a second signal from the biosensor. The processing circuitry may switch the IMD from a first mode to a second mode based on both the first preliminary determination and the second preliminary determination being that the IMD is implanted.

Implantable medical device using internal sensors to determine when to switch operational modes

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.
