Abstract
A method of minimally invasively reducing a volume of a hyper-inflated target section of diseased lung comprising the steps of introducing a bronchoscope into a patient's airway to a position adjacent the target section and equilibrating air within the target section with atmospheric air to at least partially deflate the target lung section; injecting an inflammation-causing substance into the target section to precipitate adhesion of the walls within the target lung section, preventing substantial re-inflation of the target section by occluding an airway upstream of the target section for a period of time, and removing the airway occlusion after the target section has substantially permanently been reduced in volume. The injected substance can be autologous blood or a constituent thereof.
