Devices, systems, and methods for measuring parallel tissue conductance, luminal cross-sectional areas, fluid velocity, and/or determining plaque vulnerability using temperature. In at least one embodiment of a device to obtain a parallel tissue conductance within a luminal organ, the device comprises an elongated body having a longitudinal axis extending from a proximal end to a distal end, a pair of excitation electrodes located on the elongated body at or near the distal end, a pair of detection electrodes located on the elongated body in between the pair of excitation electrodes, and a thermistor positioned along the longitudinal axis, located near the distal end and positioned proximal to the first excitation electrode and the second excitation electrode. |
