Abstract: A medical system configured for nerve modulation can include an elongate shaft, having a distal end region and a proximal end region is disclosed. Adjacent the distal end region an ablation electrode can be disposed. The system can further include a first optical fiber, having a proximal end and a distal end, extending along an outer surface of the elongate shaft, and in turn a number of (fiber Bragg Grating) FBG sensors therein. The FBG sensors can be positioned adjacent to the ablation electrode. An optical read out mechanism can be optically coupled to the optical fiber to transmit light into the optical fiber and detect light reflected from the FBG sensor. Here, the detected light, reflected from FBG temperature sensors, encodes local temperatures at each of the FBG temperature sensors.
