Abstract
A system to alleviate a symptom of chronic obstructive pulmonary disease in a lung of a patient by providing a ventilation bypass pathway which allows air to exit the lung via the bronchus or trachea. The system includes a conduit connected by an airway connection device to an artificial opening through a wall of a region of a trachea or bronchus external to the lung. The other end of the conduit is connected by a lung connection device to an opening through a visceral membrane of the lung. A flow-control device such as a filter or valve is connected to the conduit to allow exhalation via the conduit but control flow from the airway to the lung. The conduit creates a direct fluid communication between the lung of the patient and the airway of the patient which permits air to exit the lung and enter the airway via the conduit.
