Abstract

A tube of a medical device is inserted into the lung of a patient through a passage, sealed from the pleural cavity, which passes through the chest wall, parietal membrane and visceral membrane into the lung. A flange of the medical device is secured to the chest of the patient. Thus secured, a proximal opening of the tube is positioned within the lung of the patient and an external opening is positioned external to the patient, permitting gasses within the lung of the patient to escape through the chest wall by entering the distal opening, passing through the tube and venting to atmosphere through the proximal opening.
