Abstract
A sensor delivery device and methods of using the device are provided, wherein the sensor delivery device includes a sensor that is adapted to obtain a measurement that can be used to calculate cross-sectional area of a surrounding anatomical structure. In certain cases, the sensor is an electrode arrangement, wherein the electrode arrangement generates a current and measures voltage resulting from the current. The voltage measurement is then used to calculate conductivity of fluid in the surrounding anatomical structure and thus cross-sectional area.
