BRONCHIOPULMONARY OCCLUSION DEVICES AND LUNG VOLUME REDUCTION METHODS

机译:支气管肺闭塞装置和肺体积减少方法

摘要

Lung volume reduction is performed by the placement of a device (2) into a branch of the airway (34) to prevent air from entering that portion of lung. This will result in adsorption atelectasis of the distal portion of lung. The physiological response in this portion of lung is hypoxic vasoconstriction. The net effect is for a portion of lung to be functionally removed, i.e. a selected portion of lung is removed from both the circulation and ventilation. The build up of secretions is accommodated by using a valve (5, 15, 29) in the obstructive device, the valve opening upon coughing etc.
