Sealing the airway with an inflatable cuff is a feature of a supraglottic airway device. The laryngeal mask airway has a cuff at its distal part that, when inflated, presses against the pharyngeal walls to create a seal around the laryngeal inlet. This keeps ventilation effective without entering the trachea. The IGEL relies on a noninflatable gel-like cuff and seals by its shape, so no inflation is used. A bag-valve mask is just a face mask for manual ventilation and has no cuff to seal around the airway. An endotracheal tube does have an inflatable cuff, but it seals inside the trachea, not around the throat. So the device secured to the throat using an inflation cuff is the laryngeal mask airway.
