Claim One:
1. A method of treating a subject, comprising: moving a delivery device including an elongate shaft through which coolant is capable of flowing, and an ablation assembly into an airway of a bronchial tree, the ablation assembly including a cooling element coupled directly to a distal end of the elongate shaft, and an energy emitter assembly, the energy emitter assembly including a cooling channel also coupled directly at a first end thereof to a distal end of the elongate shaft, and an energy emitter coupled to the cooling channel; expanding the cooling element to an expanded position such that the cooling element is in contact with a wall of the airway, and the energy emitter extends at least partially circumferentially around the cooling element; causing energy to be delivered from the energy emitter to damage nerve tissue of a nerve trunk extending along the airway; and circulating the coolant through the elongate shaft, the cooling element, and the cooling channel of the energy emitter assembly while causing the energy to be delivered so as to cool the wall of the airway to limit or prevent cell death in tissue located between the nerve tissue and the energy emitter, and adjacent to the energy emitter.
