Intubation Stylet & Endotracheal Tube

An intubation stylet apparatus for use in medical intubation of a patient, the stylet comprising:

• an elongated tube having a distal end section, a proximal end section and an intermediate section located between the distal end section and the proximal end section;
• a grip attached to the proximal end section;
• a control lever slidably coupled to the grip;
• and
• wires having one end attached to the control lever and the other end attached to the distal end of the elongated tube;
• wherein the distal end of the elongated tube has at least three trapezoid shaped cylindrical segments, each segment, other than the most distal segment, having distal and proximate ends that are flat and the distal end of the most distal segment is a semi circle, the distal end of the elongated tube being urged to bend to a modified “s” shaped curve when the control lever is pulled to apply a tension force on the wires and to return to a straight tube when the tension force on the wires is released;
• and
• wherein the distal end segment and the intermediate segments are composed of polyethylene, polypropylene or a plastic composition where the composition of the material is controlled to insure that the distal end of the elongated tube is more flexible than the intermediate section.
