The blockade device inside the bronchial tube which makes mucus transport possible

摘要

An obstructive device prevents air from being inhaled into a lung portion to collapse the lung portion while providing mucus transport from the lung portion. When placed in an air passageway serving the lung portion, the obstructing member defines a pathway for mucus transport between the obstructing member and the air passageway. The device may include a tubular-shaped anchor to retain the device in the air passageway. A pathway for mucus transport is provided between a portion of the anchor and a portion of the obstructing device.
