Abstract
A laryngeal airway device for sealing against the laryngeal opening includes an air tube with proximal and distal ends and a sealing member attached to the distal end. The airway device includes a tubular extension or snout for delivering air directly into the laryngeal opening; the snout is tapered and “hooded” in a manner that facilitates effective positioning of the airway device. The sealing member includes a coupler for coupling the device to an introducer. Complementing the laryngeal airway device is an introducer that includes a track for receiving the coupler of the laryngeal airway device and guiding the sealing member to a sealing position with respect to the laryngeal inlet.
