Designed by Mike O'Neil, Consultant Anaesthetist at Huddersfield Royal Infirmary and ex-Sheffield junior anaesthetist, who was seeking improvements on the LMA system. Whilst sitting on a beach in Barbados in 1995 he came up with the idea of a single tube with donut cuff at the lower end, and a larger pharyngeal cuff higher up. The design prevented rotation, sealed the oesophagus from the larynx, allowed suction catheterisation of the oesophagus, allowed assisted ventilation, allowed bronchoscopy and blind intubation whilst maintaining oxygenation and ventilation, is not traumatic and didn't require a catheter mount. The Airway Management Device was introduced in 2000, and modified in 2002. Our example is the earlier version
