Abstract
A laryngeal mask assembly has a tubular shaft with a mask portion formed by a resilient skirt towards its patient end, which seals with tissue in the region of the hypopharynx. An inflatable cuff, with several annular reinforcing members, projects axially at the patient end of the assembly into the laryngeal inlet. Towards its patient end, the cuff has a flap that normally closes the passage through the cuff and prevents entry of the epiglottis. A pull cord attached with the flap enables the flap to be pulled to one side, deflecting the epiglottis and opening the passage through the cuff.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
