Abstract: An enhanced endotracheal tube utilizing a fiber optic bundle positioned in its wall section to transmit light and a reflectively coated bore to transmit images is disclosed. Additional passages formed in the wall of the endotracheal tube are adapted to receive a stylette and to act as an air passage for inflating an inflatable cuff formed on the inner end of the endotracheal tube. The light transmitted through the fiber optic bundle aids in illuminating the patient's laryngeal area and the image is reflected along the reflectively coated bore to aid the physician in intubating the patient. Alternative embodiments using a bore with a sleeve having a different refractive index from that of the tube material and an enhanced endotracheal tube for use with children are shown.
