    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: Devices, systems, and techniques for selecting a period for charging an implantable rechargeable power source are disclosed. Implantable medical devices may include a rechargeable power source that can be transcutaneously charged. A system may control a charging module to begin charging the rechargeable power source of the implantable medical device with a high power level. The system may then determine an estimated heat loss based on power initially delivered to the rechargeable power source when beginning the charging. Based on this estimated heat loss during the initial period of recharging, the system may select a boost period that includes a duration of time that the rechargeable power source is charged with the high power level.

    Abstract: Medical device recharging systems include a controller and a separate recharge device that communicate wirelessly together to provide recharging to an implantable medical device. Either the controller or the recharge device may also communicate wirelessly with the implantable medical device to obtain recharge status and other information. There may be multiple recharge devices present within communication range of the controller, and the controller may determine which recharge device to activate depending upon proximity of each recharge device to the implantable medical device. The controller may allow the recharge device that is active at any given time to change so that the patient having the implantable medical device can move about in the area where the recharge devices are located while recharging continues.

    Abstract translation: 医疗装置再充电系统包括一个控制器和一个单独的再充电装置，它们以无线方式通信在一起以向可植入医疗装置提供再充电。 控制器或充电设备也可以与可植入医疗设备进行无线通信，以获得充电状态和其他信息。 在控制器的通信范围内可能存在多个充电设备，并且控制器可以根据每个再充电设备与可植入医疗设备的接近度来确定要激活的再充电设备。 控制器可以允许在任何给定时间处于活动状态的再充电设备改变，使得具有可植入医疗设备的患者可以在充电设备所在的区域中移动，同时继续充电。

    Abstract: Devices, systems, and techniques for controlling charging power based on a cumulative thermal dose to a patient are disclosed. Implantable medical devices may include a rechargeable power source that can be transcutaneously charged. An external charging device may calculate an estimated cumulative thermal dose delivered to the patient during charging over a predetermined period of time. Based on the estimated cumulative thermal dose, the external charging device may select a power level for subsequent charging of the rechargeable power source. In one example, the charging device may select a high power level when the cumulative thermal dose has not exceeded a thermal dose threshold and select a low power level when the cumulative thermal dose has exceeded the thermal dose threshold.
