Abstract
A pulmonary treatment system includes a compact configuration for delivery to an airway of a patient. An energy delivery system of the pulmonary treatment system delivers ultrasound energy to target nerve tissue in or along an airway wall of the airway radially outward from surface tissue to reduce airway resistance in a downstream airway. The pulmonary treatment system may protect tissue in the airway wall of the airway located between the target nerve tissue and the ultrasound energy delivery system by a coolant system that may also act as a coupling fluid for the emitted ultrasound energy.
