Abstract
A ventilation bypass system which alleviates symptoms of chronic obstructive pulmonary disease by allowing air to exit the lung of a patient through the thoracic wall bypassing the natural airways. A pleurodesis is formed between the visceral and parietal membranes surrounding a lung and an opening is made through the thoracic wall into the lung via the pleurodesis. The ventilation bypass system includes a conduit placed through the opening in the thoracic wall into the lung, a flange for securing the conduit to the thoracic wall and preventing over-insertion of the conduit, and a flow control device for controlling flow of material out of the lung.
