Abstract: A catheter is disclosed including an elongated shaft having a distal end and a proximal end, where the catheter includes a thermal element at the distal end thereof. The thermal element may be used in an ablation procedure or other procedure to heat a tissue adjacent a vessel. The configuration of the distal end of the elongated shaft at or near the distal tip may encourage the cooling of or transferring of heat from the vessel wall. The configurations may include protrusions extending from and indentations extending into the shaft, which may manipulate the flow of fluid through a vessel in which the catheter has been inserted. Alternatively or additionally, a cap or thin insulative layer may be placed at or near the distal tip of the catheter shaft to cool the wall of the vessel.

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.
