Abstract
A partially-implantable pneumostoma management device maintains the patency of a pneumostoma while controlling the flow of material through the pneumostoma. A tube of the pneumostoma management device is placed through the chest wall into the lung. The tube comprises a plurality of holes in the distal end to allow the entry of gases and non-gaseous discharge from the lung. A contact surface prevents over-insertion of the tube while releasably securing the device to the chest of the patient. The contact surface has features to reduce irritation of the skin of the chest.
