1. An intraluminal or bronchoscopic method for treating obstructive lung disease comprising:
determining at least one discrete band-shaped area along a surface of an airway to ablate to form a band-shaped lesion having a width and a depth;
computing a dose of vapor to aim at the surface of the airway to form the band-shaped lesion based on a set of ablation parameters, the set of ablation parameters selected from the group consisting of (a) anatomic, (b) device and controller, and (c) treatment-specific parameters;
advancing a vapor ablation catheter into the airway of a patient lung and aiming at least one egress port of the vapor ablation catheter directly towards the surface of the airway; and
delivering vapor from the at least one egress port into the surface of the airway and according to said computed dose of vapor, thereby causing formation of the band-shaped lesion wherein the dose of vapor from the computing step is predetermined to cause the band-shaped lesion to have a depth in the range from 0.1 to 0.7 mm, and a width in the range from 5 to 20 mm.
