Abstract

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 (330), the mask portion including a backplate (312) and a cuff (334), the mask portion 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, 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.
