Abstract:
1. A method for treating a lung of a patient through a thoracic wall, parietal membrane, pleural cavity, and visceral membrane, the method comprising the steps of: (a) receiving a device including, (b) introducing the evacuation structure through the thoracic wall and the parietal membrane such that a proximal end of the access port is located external to the patient, and the distal end of the access port and the evacuation structure are located in the pleural cavity; (c) evacuating air from the pleural cavity through the evacuation structure and access port so that parietal and visceral membranes contact the evacuation structure; (d) delivering a chemical agent from the evacuation structure such that the chemical agent is delivered only to a localized region of the parietal and visceral membranes adjacent the evacuation structure which surrounds the distal end of the access tube, to create a localized adhesion between the parietal membrane and visceral membrane restricted to said localized region; (e) waiting until said localized adhesion has formed; and (f) introducing an instrument through the access port, through said localized adhesion, through the visceral membrane, and into parenchymal tissue of the lung wherein the evacuation structure comprises a plurality of holes in fluid communication with the access port and extending through the peripheral edge of the flat disk and wherein step (c) comprises evacuating air from the pleural cavity through the plurality of holes in the evacuation structure and through the access port so that parietal and visceral membranes contact the evacuation structure.
