Abstract: A lesion characterization process is disclosed. According to one aspect, a method includes obtaining measurements of at least one of an impedance magnitude, impedance phase, a temperature, and electrical properties of tissue of the lesion. The method further includes determining at least one lesion property including at least one of a depth of the lesion, percent transmurality of the lesion, lesion surface area and lesion volume based on at least one of the obtained measurements.

Abstract: A method of treating or preventing acute respiratory distress syndromes (ARDS) includes advancing a cryogenic treatment element into a target bronchus of a mammal and exchanging cryogenic energy between the target bronchus and the cryogenic treatment element for a predetermined period of time until a target temperature of the target bronchus is reached to cause neuropraxia of nerves within the target bronchus.
