Intubation system, method, and device

An intubation device utilizes a steerable endotracheal tube guide, a novel mechanism to automatically position an endotracheal tube at the laryngeal opening, and a novel system for soft tissue retraction to improve visualization of the laryngeal opening. An ETT is positioned within an overtube having proximal and distal ends and a flexible tip. The distal end houses a feeder mechanism for displacing the endotracheal tube through the overtube. A hood includes a stem, base, and expandable body, and may be affixed to the overtube's distal end. The ETT-containing overtube is precisely positioned at a laryngeal opening via positioning effects of body expansion, activation of a tip director, and/or flexible tip articulation. Unhindered visualization of the laryngeal opening is achieved by the expandable body, pushing the soft tissue outwardly and extensibly. An actuation module controls the feeder mechanism as well as the flexible tip to position flexible tip and endotracheal tube.
