Abstract
Disclosed herein is a method for treatment of emphysema by reducing the volume of the pulmonary alveoli or alveolar sacs which have been anomalously expanded with destruction by emphysema. The method includes a step (a) of inserting a catheter into a bronchus or bronchiole, a step (b) of injecting through said catheter a film-forming agent into the respiratory region including the pulmonary alveoli or alveolar sacs, thereby forming a film on the inner wall of said respiratory region, and a step (c) of shrinking said pulmonary alveoli or alveolar sacs.
