    Abstract: Devices, systems, and techniques for estimating energy transfer to tissue of a patient during battery charging for an implantable medical device are disclosed. Implantable medical devices may include a rechargeable power source that can be transcutaneously charged. An external charging device may calculate an estimated energy transfer to tissue of the patient that may include a resistive heat loss from the rechargeable power source and/or electromagnetic energy transfer directly to tissue. Based on the estimated energy transfer, the external charging device may select a power level for charging of the rechargeable power source. In one example, the charging device may select a high power level when the estimated energy transfer has not exceeded an energy transfer threshold and select a low power level when the estimated energy transfer has exceeded the energy transfer threshold.

    Abstract: Devices, systems, and techniques for managing heat generated in coils for wireless energy transmission are disclosed. Inductive coupling between two coils (e.g., a primary coil and a secondary coil) may be used to recharge the power source of an implantable medical device. A phase change material may be thermally coupled to the primary coil to absorb heat generated during the inductive coupling and reduce temperature increases of the primary coil. In one example, the phase change material may be configured to absorb heat from an energy transfer coil. A housing may be configured to contain the phase change material and a coupling mechanism may be configured to removably attach the housing to the energy transfer coil.

    Abstract: Far field telemetry operations are conducted between an external device and an implantable medical device while power is being transferred to the implantable medical device for purposes of recharging a battery of the implantable medical device. The far field operations may include exchanging recharge information that has been collected by the implantable medical device which allows the external device to exercise control over the recharge process. The far field operations may include suspending far field telemetry communications for periods of time while power continues to be transferred where suspending far field telemetry communications may include powering down far field telemetry communication circuits of the implantable medical device for periods of time which may conserve energy. The far field operations may further include transferring programming instructions to the implantable medical device.

    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. In one example, a temperature sensor may sense a temperature of a portion of a device, wherein the portion is non-thermally coupled to the temperature sensor. A processor may then control charging of the rechargeable power source based on the sensed temperature.

    Abstract: System for transcutaneous energy transfer. An implantable medical device, adapted to be implanted in a patient, has componentry for providing a therapeutic output. The implantable medical device has an internal power source and a secondary coil operatively coupled to the internal power source. An external power source, having a primary coil, provides energy to the implantable medical device when the primary coil of the external power source is placed in proximity of the secondary coil of the implantable medical device and thereby generates a current in the internal power source. An alignment indicator reports the alignment as a function of the current generated in the internal power source with a predetermined value associated with an expected alignment between the primary coil and secondary coil.
