Probe devices with temperature sensors and related systems and methods
Electrode devices are provided having certain thin film components, including at least one thin film contact and a temperature sensor associated with the contact. The temperature sensor can be used to monitor the temperature during use of the electrode device, including during electrical stimulation or ablation. Further, the temperature sensor can be used to identify the most effective temperature for stimulation or ablation.
