THERMAL MANAGEMENT OF MEDICAL DEVICES

A rechargeable implantable neuro stimulator may include a neuro stimulation waveform generator configured to generate neuro stimulation signals. The neurostimulator may further include at least one electrode, at least one rechargeable battery configured to power the neurostimulator, and a coil for receiving power. The coil may be electrically connected to the circuitry for use in recharging the battery using the power received by the coil. The neurostimulator may further include two or more sensors configured for use in determining temperature and a controller. The controller may be configured to: control generation of neurostimulation signals from the neurostimulation waveform generator to deliver neurostimulation using the at least one electrode, perform sensor processing using the two or more sensors to determine a temperature event, and control recharging of the rechargeable battery using a recharging process including modify the recharging process to reduce heating in response to determining that the temperature event occurred.
