Patent Primary Examiner
A treatment of obstructive lung disease includes aiming a condensable vapor towards the airway wall, causing a band-shaped lesion to grow to a depth into the airway wall. Ablation parameters are set to control the depth of the band-shaped lesion to encompass the epithelial layer and exclude the smooth muscle layer of the airway. A wide variety of configurations of the vapor delivery are described to create ablation patterns in the airways of the patient with particular emphasis on treating chronic bronchitis.
