Abstract: A microwave ablation probe system includes a coolant delivery system to deliver coolant to a microwave ablation probe; a microwave generator to deliver microwave energy to the microwave ablation probe; and a computing system in communication with a thermal sensor on the microwave ablation probe to collect temperature data over time from the thermal sensor, wherein the computing system is configured to calculate the measured temperatures by the thermal sensor over time to determine if the coolant delivery system is cooling the microwave ablation probe, and provide feedback on ablation procedure progress.

Abstract: The present disclosure includes methods, devices, and systems for cochlear implants. One method embodiment for cochlear implant signal processing includes processing a differential analog audio signal using amplitude modulation and pulse-width modulation. The method includes driving a transmission coil on an external unit of the cochlear implant with the pulse-width and amplitude modulated signal. The method also includes driving a reception coil on an internal unit of the cochlear implant with an output of the transmission coil.
