The tube has a round cross-section along the majority of its length but includes a relatively short section that is of a triangular cross-section. This triangular cross-section is positioned along the tube to contact the larynx and matches the shape of the larynx. A cuff extends about the tube below the triangular cross-section area and a pilot tube is provided which connects via a cuff inflation lumen in the wall of the tube to the cuff. |
