Which airway device is secured in the throat via an inflation cuff, though its seal is not as effective as an endotracheal tube?

The device being described is a laryngeal mask airway. It is a supraglottic airway that sits in the pharynx with an inflatable cuff around the laryngeal inlet to create a seal. This seal is adequate for ventilation but not as robust or protective as the seal an endotracheal tube achieves inside the trachea, which is why an endotracheal tube provides a more secure airway and better protection against aspiration. The iGel uses a gel-like, non-inflatable cuff, so its sealing mechanism differs from an inflated cuff. The nasal cannula simply delivers oxygen and does not secure the airway.
