Abstract: A medicament delivery device (“MDD”) having a delivery tube and a laryngeal mask having an anterior patient-contacting surface. In some embodiments of the invention, the laryngeal mask has an epiglottis-holding ridge. In some embodiments of the invention, the laryngeal mask has a cuff-portion providing at least a portion of an anterior patient-contacting surface, the cuff-portion being shaped and positioned to create a side-groove facing away from the anterior patient-contacting surface. In some embodiments of the invention, the laryngeal mask has a plurality of ridges on a posterior-side of the laryngeal mask opposite the anterior patient-contacting surface (the “posterior-side ridges”), the posterior-side ridges being shaped and positioned relative to the anterior patient-contacting surface so as to push against the patient and thereby push the anterior patient-contacting surface against the patient.

Abstract: Methods of delivering medicament and a medicament delivery device (“MDD”) are described. Such an MDD may have a laryngeal mask configured to fit against a patient at an area surrounding the patient's laryngeal inlet, and thereby cover a laryngeal inlet of the patient, and a delivery tube having interior wall surfaces defining a medicament channel. Medicament may be conveyed via the medicament channel toward the laryngeal mask. The MDD may have at least two gas channels. The gas channels may be in gas-communication with the laryngeal mask.
