The Bougie ET tube introducer is a device that assists the Intermediate or Paramedic in difficult intubations. Once the Bougie is passed through the vocal cords, the curved tip of the Bougie will rub along the cartilagenous rings on the inside of the trachea and cause the Bougie to vibrate in the provider's fingers. I use the example of the "rumble strips" along an interstate highway. The ET tube can then be passed over the Bougie. The Bougie is removed, the ET cuff inflated, proper intubation verification is performed, and the tube is secured.
