An endotracheal tube, comprising: an elongated tube with a distal end configured to be placed inside a trachea and a proximal end connectable to a ventilator, the tube having a concave and a convex surface (8, 9) which correspond to a patient's anterior and posterior side, respectively; a plurality of longitudinal passages (18,19) having predetermined diameters extending within the tube, each of the plurality of passages (18,19) configured to receive a controlling wire (4,6) therethrough; a bite block having a predetermined length positioned along the tube, the bite block having a first and second surface that align with the convex and concave surfaces (8,9) of the tube and at least one fulcrum; at least one opening formed in the first and second surface of the bite block, the at least one opening configured to receive the controlling wire (4,6); a removable lever having a ring that removably attaches to the at least one fulcrum and at least one slit that aligns with the at least one opening formed in the first and second surface of the bite block, the removable lever controlling a bi-directional movement of the distal end; a flexible portion of the tube proximate the distal end, the flexible portion comprising: a pair of diametric notches (22,23) with rounded edges formed within the tube and extending through the plurality of passages, a first notch proximate the convex surface of the tube and a second notch proximate the concave surface of the tube; a first membranous wrap surrounding the diametric notches (22,23); a first and second hole (29,30) positioned on opposite sides of the diametric notches (22,23) and configured to receive a controlling wire (5,7); a second membranous wrap encompassing the first membranous wrap and the first and second holes (29,30); and a third membranous wrap encompassing the first and second membranous wraps (3,27), the third membranous wrap in fluid communication with at least one of the plurality of passages so that air can be injected to inflate the third membranous wrap; an insertion tip formed at the distal end of the tube; and a connector mounted on the proximal end of the tube, the connector adapted to secure a video imaging stylet to the tube. an elongated tube with a distal end configured to be placed inside a trachea and a proximal end connectable to a ventilator, the tube having a concave and a convex surface (8, 9) which correspond to a patient's anterior and posterior side, respectively;
