The Ambu Aura40 is the world's first reusable laryngeal mask to feature a built-in curve that carefully replicates natural human anatomy and is molded directly into the tube to make correct insertion easy without abrading the upper airway. It also features a reinforced tip, which helps prevent folds during insertion that can cause improper positioning and possible airway leak, while its extra soft cuff ensures the best possible seal with least possible internal pressure.
