Claim:
1. An endotracheal tube with a main tracheal tube that defines a longitudinal cylindrical internal space that is divided lengthwise by a dividing wall to define two internal and adjacent tracheal lumens within the main tracheal tube, the endotracheal tube being adapted for a tracheal cuff sealing by way of a tracheal cuff of a patient's trachea, the tracheal cuff being supported from the main tracheal tube and being further adapted for a bronchial cuff sealing by way of a bronchial cuff of a bronchus of the patient, the bronchial cuff being supported from a bronchial tube that extends downward from the main tracheal tube and which defines an internal bronchial tube lumen extending one of the tracheal lumens comprising: a) the dividing wall forms two sealing attachment lines lengthwise down an inside surface of the main tracheal tube, whereby the two sealing attachment lines are offset from a midline of the tracheal tube such that the dividing wall extends away from the inside surface at points that are offset from the midline of the tracheal tube, wherein the cross section areas of the two internal and adjacent tracheal lumens are about equal when the dividing wall is at rest; b) at a lower end of the main tracheal tube, the tracheal cuff is located above a first opening of the main tracheal tube defined at a distal end of the tracheal lumen that does not extend to the bronchial tube lumen; and c) the bronchial tube lumen terminates at a distal bronchial opening and the bronchial cuff is located above the distal bronchial opening.
