Abstract
A method to treat a human patient including: advancing a catheter through a natural airway of the patient and positioning a distal portion of the catheter in the natural airway of a lung of the patient to a target region in the lung, injecting a conductive hypertonic saline solution having a concentration of at least 5% of sodium chloride by weight/volume from the distal portion of the catheter into the target region; delivering energy from the distal portion into the conductive hypertonic saline solution in the target region, wherein the energy heats the liquid in the portion of the airway, and ablating the target region with the heated liquid.
