Abstract
Impedance devices and methods to use the same to obtain luminal organ measurements. 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 first electrode located along the elongated body at or near the distal body end, the first electrode configured to obtain one or more conductance values within a mammalian luminal organ within an electric field, 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 first electrode.

An impedance device, comprising:
- an elongated body having a distal body end;
- and
- a first electrode located along the elongated body at or near the distal body end, the first electrode configured to obtain one or more conductance values within a mammalian luminal organ within an electric field;
- 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 first electrode.
A method of using an impedance device, the method comprising the steps of:
- introducing at least part of an impedance device into a mammalian luminal organ at a first location, the impedance device comprising:
- an elongated body having a distal body end, and
- a first electrode located along the elongated body at or near the distal body end, the first electrode configured to obtain one or more conductance values within a mammalian luminal organ within an electric field;
- providing electrical current to the first electrode and a first external electrode not coupled to the elongated body to generate the electric field, the first external electrode positioned upon or within a mammalian body having the mammalian luminal organ;
- obtaining at least one conductance value using the impedance device within the electric field;
- and
- calculating a measured parameter of the mammalian luminal organ based in part upon the at least one conductance value.
