Abstract
A closed suction system module is provided. In one embodiment, the closed suction system module includes a coupling member configured to couple to a suction port of a multi-port manifold or endotracheal tube adapter (e.g., dual-port or tri-port adapter). In one embodiment, the closed suction system module includes a suction catheter configured to clean the interior surfaces of body-inserted tubes or artificial airways (alone or in addition to suctioning natural airways or portions of the respiratory tract or other body lumens). The suction catheter may include a cleaning portion at a distal portion of the suction catheter (e.g., near the distal end or tip of the suction catheter). In some embodiments, the cleaning portion includes at least one expandable cleaning member (e.g., balloon, sleeve, wiper).
