Laryngeal mask
Abstract:
A laryngeal mask includes an airway tube having an inner lumen and a distal end; and a mask portion connected at a proximal end thereof to the distal end of the airway tube and having a distal tip opposite the proximal end. The mask portion includes an inflatable cuff including an anterior cuff surface, and a wedge portion including a stabilization surface and two walls connected to the inflatable cuff and extending toward from the stabilization surface, the stabilization surface extending from the distal tip of the mask portion toward the distal end of the airway tube at a wedge angle of between about 12 and 30 degrees, the wedge angle formed between the stabilization surface and the anterior cuff surface when the inflatable mask is inflated. The stabilization surface is transversely and longitudinally substantially flat to stabilize the laryngeal mask in use.
