text: An endotracheal tube comprising an elongated flexible tube having a set curvature and provided with a distal end tapered on two opposed sides relative to said curvature and terminating in a central transverse strut, openings in said tapered sides communicating with the the usual resistance tube, said strut defining the forward ends of said open-' ings, the leading portion of said strut having a forwardly and downwardly inclined surface relative to the upper and lower tube surfaces of said set curvature and terminating in a relatively small flexible extension coextensive with said lower tube surface, and a catheter tube inserted within the endotracheal tube, said catheter tube also having a set curvature corresponding to the curvature of the endotracheal tube, and a mark on the outer end of said catheter tube aligned longitudinally with the upper for rotating said catheter tube in a direction to effect passage of the same through the distal opening desired, the inner surface of said central strut defining the forward ends of said openings'being rounded and tapered to facilitate passage of the catheter tube through the opening desired.
