Abstract
A method for decreasing responsiveness or decreasing resistance to airflow of airways involves the transfer of energy to or from the airway walls to prevent or reduce airway constriction and other symptoms of lung diseases. The treatment reduces the ability of the airways to contract during an acute narrowing of the airways, reduces mucus plugging of the airways, and/or increases the airway diameter. The methods according to the present invention provide a longer duration and/or more effective treatment for lung diseases than currently used drug treatments, and obviate patient compliance issues.
