Abstract
A wireless charger device is configured to charge an implantable medical device (IMD). A patient controller obtains one or more power parameters from the charger device during charging of the IMD. The patient controller estimates a temperature range of the IMD using the one or more power parameters from the charger device and compares to a heating threshold. The patient controller then determines whether one or more spacers are recommended in response to the comparison. The one or more spacers are removably attached to the wireless charger device and are configured to lay in a position between the wireless charger device and a patient's skin to increase a charging path.
