Claim Text:
1. A method of removing a stenotic lesion from a vessel, comprising the steps of: (a) measuring a first luminal size parameter at a first location within a vessel and a second luminal size parameter at a second location within the vessel; (b) determining a preferred luminal size parameter range based upon the first luminal size parameter and the second luminal size parameter; (c) operating a treatment device positioned at the second location to increase the second luminal size parameter, the treatment device comprising at least one sizing portion configured to obtain the first luminal size parameter and the second luminal size parameter using impedance and at least one treatment portion operable to remove at least part of a stenotic lesion; (d) measuring a then-current luminal size parameter at the second location; (e) comparing the then-current luminal size parameter to the preferred luminal size parameter range; and (f) if the then-current luminal size parameter does not fall within the preferred luminal size parameter range, repeating steps (c), (d), and (e) until the then-current luminal size parameter falls within the preferred luminal size parameter range.
