  • Patent number: 5033466
    Abstract: An improved double-cuffed endotracheal tube designed for insertion through the mouth of a patient to provide a passage for artificial respiration. The device includes an elongated flexible tube having proximal and distal end portions, the distal end portion designed for insertion into a patient and the proximal end portion capable of connection to an artificial respirator. The tube includes a lower inflatable-deflatable cuff located above the distal end portion and secured to and encircling the tube. When properly positioned and inflated, the lower cuff sealingly engages the inner wall of the trachea below the larynx and prevents secretions from traveling into the upper trachea or larynx. The tube also includes an upper inflatable-deflatable foam-filled cuff secured to and encircling the tube above the lower cuff. The upper cuff is located on the tube at a predetermined point for positioning in the larynx between the vocal cords and cricoarytenoid joint.
