Abstract:
1. A method that uses a lung-volume-reduction device having a housing adapted to be secured to a chest of a patient, a conduit projecting from the housing, and a gas outlet positioned within the housing and in fluid communication with the conduit, wherein the method comprises: (a) inserting the conduit through an aperture in the chest wall of the patient into the lung of the patient, wherein the aperture passes from external to the patient through skin of the chest wall, through a parietal membrane and through a visceral membrane into the lung, and wherein the visceral membrane is sealed to the parietal membrane around the aperture to prevent pneumothorax; and (b) securing the housing to the chest of the patient external to the patient so that air within the lung may vent to atmosphere external to the patient through the conduit via the housing.
