Abstract

See full text

An artificial airway is provided for permitting medical personnel access to a patient's airway. The artificial airway includes a foam cuff laryngeal mask having an air tube, a pilot tube, and a laryngeal mask. The air tube and the laryngeal mask cooperate to form a gas passage that permits gases to flow through the foam cuff laryngeal mask. The laryngeal mask includes a foam cuff having a pliable sheath filled with a resilient material. Air is drawn out of the resilient material through the pilot tube which causes the foam cuff to deflate. The foam cuff laryngeal mask is then inserted into the patient's airway and positioned over the larynx. Air is allowed to enter the pilot tube and the resilient material expands so that the foam cuff forms a substantial seal with the larynx.
