<p>A collateral ventilation bypass trap system (100) directly linked with a patient's lung or lungs may be utilized to increase the expiratory flow from the diseased lung or lungs (108), thereby treating one aspect of chronic obstructive pulmonary disease. The system (100) includes a trap (102), a filter/one-way valve (106), an air carrying conduit (104) and a retention device for securing system elements in position. The system (100) also includes a flow restriction device (1200) for controlling the flow of air through the air carrying conduit (104). In one embodiment a flow control valve assembly for a collateral ventilation bypass system (100) is described. The valve comprises at least one device connected, at a predetermined site, to at least one lung (108) for removing trapped gases in the lung; and a valve assembly for adjusting the flow of gases from the at least one lung through the at least one device.</p> |
