Abstract
Disclosed is a flow control device for a bronchial passageway. The device can includes a valve member that regulates fluid flow through the flow control device, a frame coupled to the valve member, and a membrane attached to the frame. At least a portion of the flow control device forms a seal with the interior wall of the bronchial passageway when the flow control device is implanted in the bronchial passageway. The membrane forms a fluid pathway from the seal into the valve member to direct fluid flowing through the bronchial passageway into the valve member.
