    Abstract: Devices, systems, and techniques for monitoring the temperature of a device used to charge a rechargeable power source are disclosed. Implantable medical devices may include a rechargeable power source that can be transcutaneously charged. The temperature of an external charging device and/or an implantable medical device may be monitored to control the temperature exposure to patient tissue during a charging session used to recharge the rechargeable power source. In one example, a temperature sensor may sense a temperature of an internal portion of a device, wherein the housing of the device is not directly thermally coupled to the temperature sensor. A temperature for the housing of the device may then be estimated based on the sensed temperature provided by the non-thermally coupled temperature sensor. A processor may then control charging of the rechargeable power source based on the determined temperature for the housing.

    Abstract: Techniques for estimating the temperature of an external portion of a medical device are described. In an example, processing circuitry may determine a temperature sensed by at least one temperature sensor of an internal portion of the device, and determine, based on an algorithm that incorporates the temperature of the internal portion of the device, an estimated temperature of a second portion of the device, wherein the algorithm is representative of an estimated temperature difference between the first portion of the device and the second portion of the device based at least in part on a dynamic transfer function that operates in a time-domain.

    Abstract: Devices, systems, and techniques are configured for cooling tissue during recharge of an implantable medical device (IMD) battery. In one example, a method includes charging, by an inductive charger, a rechargeable battery of an implantable medical device (IMD) within a patient, wherein the IMD comprises a housing that houses the rechargeable battery, and wherein a primary coil of the inductive charger is positioned above a region of skin of the patient proximate to the IMD. The example method further includes cooling, by a heat exchanger, the region of skin below a normal ambient surface temperature of the region of skin, wherein the heat exchanger is interposed between the primary coil and the region of skin.
