Claim:
1. An impedance system, comprising: an impedance device comprising: a first external electrode for placement upon or within a mammalian body, the first external electrode not coupled to the elongated body; and a second external electrode for placement upon or within a mammalian body, the second external electrode not coupled to the elongated body; wherein the first electrode is configured to generate the electric field within a mammalian body when the first external electrode is positioned upon or within the mammalian body and when the first electrode and the first external electrode are activated; wherein the second electrode and the second external electrode are configured to detect the electric field generated by the first electrode and the first external electrode when the second external electrode is positioned upon or within the mammalian body; and wherein a measured parameter of the mammalian luminal organ calculatable from at least one conductivity measurement can be calculated based in part upon the one or more conductance values obtained by the first electrode.
