Abstract
An endotracheal tube is disclosed that allows a patient to speak while intubated. The endotracheal tube includes a balloon for seating against the trachea and a collapsible portion proximal to the balloon that aligns with the vocal cords. The collapsible portion may be held open by an inner tube which translates within the endotracheal tube. Suction and balloon inflation conduits span the collapsible portion so that suction and balloon inflation may be performed while the patient is speaking. A small distal tube that bypasses the balloon provides some airflow while the patient speaks.
