Abstract
The present disclosure comprises a system, catheter and method for measuring the cross-sectional areas and pressure gradients in any hollow organ, such as, for example, blood vessels. One embodiment of such a method includes the steps of introducing an impedance catheter into a treatment site, providing electrical current flow to the treatment site, injecting a first solution and measuring a first conductance value, injecting a second solution and measuring a second conductance value, and calculating the cross-sectional area of the treatment site, in part, based on the first and second conductance values.
