Abstract
The disclosure of the present application provides for a system for measuring cross-sectional areas and pressure gradients in luminal organs. The disclosure of the present application also provides a method and apparatus for measuring cross-sectional areas and pressure gradients in luminal organs, such as, for example, blood vessels, heart valves, and other visceral hollow organs. In at least one embodiment, a method for measuring a cross-sectional area of a targeted treatment site comprises the steps of introducing a device, injecting two solutions, measuring a first conductance, moving the device, injecting two solutions, measuring a second conductance, and calculating cross-sectional areas based upon the two conductance measurements.
