  • Patent number: 6830049
    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.
    Type: Grant

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. The introducer may include an epiglottic engager on a distal end to engage the epiglottis and retain it while the sealing member is being tracked to engagement with the laryngeal inlet.

  • Patent number: 6338343
    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.
