ABSTRACT:
An 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 sealing member has a distal portion with a pair of opposing lateral flanges for engaging the cricoid cartilage to laterally align the sealing member with respect to the laryngeal inlet. The sealing member has a compressible anterior surface that contacts and seals against the laryngeal inlet. A tubular extension of the distal end of the air tube projects through and beyond the compressible anterior surface. The sealing member has a pronounced sigmoid shape having a lower section which, together with the tubular extension, creates a hook that provides an end point for accurate cephalad-caudad depth placement of the sealing member against the rim of the laryngeal inlet.
