Methods for treating airways

Abstract

This relates to treating airways in a lung to decrease asthmatic symptoms. The also includes steps of measuring a parameter of an airway at a plurality of locations in a lung, identifying at least one treatment site from at least one of the plurality of locations based on the parameter, and applying energy to the treatment site to reduce the ability of the site to narrow.

1 . In a patient diagnosed with asthma, a method of treating airways in a lung of the patient to decrease symptoms of the asthma, the method comprising:
 stimulating an airway in the lung;   after stimulating the airway, measuring a parameter of the airway at a plurality of locations in the lung;   identifying a plurality of treatment sits from the plurality of locations based on the measured parameter at the plurality of locations;   inserting an instrument into the lung; and   applying thermal energy to the identified treatment sites via the instrument to reduce the resistance to airflow at the identified treatment sites.
