Abstract: An oropharyngeal device, for example, an endotracheal tube or a laryngeal mask airway, intended for insertion into a patient includes a tube portion defining a lumen which permits flow of a ventilating gas to the patient who may be under anesthesia for performance of surgery. The device includes a reinforcement member in a bite-resistant zone, which keeps the lumen open during patient biting to prevent occlusion of the lumen and/or interruption of the flow of ventilating gas. The reinforcement member can have a number of adjacent or closely-spaced wire turns or another suitable structure, and can cooperate with the tube portion to provide good bite-resistance. The tube portion optionally can be yieldable in the bite-resistant zone and provide cushioning during biting to inhibit dental or other damage.
