The AuraGain™ (Ambu®, Denmark) is intended for use as an alternative to a face mask for achieving and maintaining control of the airway during routine and emergency anaesthetic procedures. The gastric channel of AuraGain™ may be used as a conduit for passing a gastric tube into the stomach for removal of air and gastric fluids. It is intended for use as a conduit for an endotracheal tube in "can't intubate – can't ventilate" scenarios. It may also be used to establish a clear airway during resuscitation in profoundly unconscious patients with absent glossopharyngeal and

The mask is designed to conform to the contours of the hypopharynx with its lumen facing the laryngeal opening. When correctly inserted, the distal tip of the cuff rests against the upper oesophageal sphincter. It is anatomically shaped with an

polyvinylchloride, it is more flexible and less traumatic. Its fixed, anatomically curved shape is elliptical in cross section and aids easier insertion. It has two separate drain channels. At the machine end, they begin as the male and female suction ports. The channels then enter a chamber behind the cuff bowl. At the patient end, the chamber ends at the tip of the cuff. The device is flexible and stays in place if the patient's head is mobilised. A built-in bite block reduces the potential for damage to, or obstruction of the airway tube in the event of biting. Additionally, the LMA-Protector™ is available with a pilot balloon or the integrated Cuff Pilot™. The Cuff Pilot™ enables constant visualisation of intracuff pressure inside the mask cuff that provides easier adjustment and is colour coded for inflation pressure [74].
