Abstract
Single injection methods for obtaining conductance measurements within luminal organs using impedance devices. In at least one method embodiment, the method is performed by introducing at least part of an impedance device into a mammalian luminal organ, the impedance device comprising an elongated body and a detector positioned along the elongated body, obtaining conductance measurements indicative of a fluid native to the mammalian luminal organ and indicative of a fluid injection while the detector is present within and outside of the lumen of the outer sheath, and calculating a size parameter of the mammalian luminal organ based in part upon some of the obtained conductance measurements.
