Abstract:
1. A method for measuring a cross-sectional area of a targeted treatment site, the method comprising the steps of: introducing a device into a treatment site; injecting a volume of a first solution having a first concentration and a first conductivity and injecting a volume of a second solution having a second concentration and a second conductivity at a first position of the treatment site; measuring a first treatment site conductance at the first position of the treatment site; moving the device to a second position of the treatment site; injecting a volume of the first solution having a first concentration and a first conductivity and injecting a volume of the second solution having a second concentration and a second conductivity at the second position of the treatment site; measuring a second treatment site conductance at the second position of the treatment site; calculating cross-sectional areas of the first position and the second position of the treatment site; and calculating a total conductance for a distance between the first position and the second position of the treatment site.
