The invention relates to a laryngeal mask airway device 300 to facilitate lung ventilation in an unconscious patient, comprising a curved or flexible tube 310 opening at one end into the interior of a hollow mask portion 334, the mask portion 334 including a back plate 312 and a cuff 336. The mask portion is shaped to conform to and to fit readily into the actual and potential space behind the larynx and to seal around the circumference of the laryngeal inlet without penetrating into the interior of the larynx. The mask 300 is characterized in that at least a portion of the surface of the device includes parylene. The parylene provides a low-friction surface for improved insertion of the artificial airway device. |
