摘要：
Devices and systems to measure luminal organ parameters using impedance. In at least one embodiment of an impedance device of the present disclosure, the impedance device comprises an elongated body having a distal body end and a pair of detection electrodes positioned in between a pair of excitation electrodes located at or near the distal body end, the pair of detection electrodes configured to obtain one or more conductance values within a mammalian luminal organ within a field generated by the pair of excitation electrodes, wherein a measured parameter of the mammalian luminal organ can be calculated based in part upon the one or more conductance values obtained by the device and a known distance between the pair of detection electrodes.
