Abstract
An endotracheal tube has a proximal end and a distal end and includes a tracheal portion having an opening at the proximal end and a bronchial portion attached at an angle to the tracheal portion. The bronchial portion has an opening at the distal end of the endotracheal tube. A balloon is positioned within the endotracheal tube that blocks the flow of a gas through the bronchial portion of the endotracheal tube when inflated. The endotracheal tube has an opening between the proximal end and the balloon. The opening is positioned to allow ventilation of the lung opposite the lung into which the bronchial portion is adapted to extend into. The endotracheal tube may include a carinal seating mechanism which may be located near the junction between the tracheal portion and the bronchial portion of the endotracheal tube. The endotracheal tube further may also include an inflatable bronchial extension tube.
