  • Patent number: 10314993
    Abstract: A laryngeal mask (1) comprising an air-way tube (2) and a mask portion (6) with an inflatable cuff (8) which is arranged around the airway tube (2) at the distal end thereof. A gastric tube (12) which extends at least partially along the outer surface of the airway tube (2), penetrates through the wall of said inflatable cuff (8) at a first location, extends through said inflatable cuff (8), and ends in a connection to an opening (12) in the wall of the cuff at a second location at the tip part of the laryngeal mask, so as to provide a passage through said circumferential cuff. With respect to a central mirror symmetry plane said gastric tube extends along the outer surface of the airway tube (2) in an asymmetrical manner, through said inflatable cuff (8) at the first location arranged asymmetrically with respect to said central plane, through said inflatable cuff (8), and ends in the connection to the wall of the cuff (8) at the second location at the tip part.

  • Publication number: 20160101254
    Abstract: A laryngeal mask for use in a patient comprises 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 comprises an inflatable cuff including an anterior cuff surface configured to contact the patient's tissue when the inflatable cuff is inflated; and a wedge portion including a stabilization surface and two walls connected to the inflatable cuff and extending therefrom 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, whereby the stabilization surface is transversely and longitudinally substantially flat to stabilize the laryngeal mask in use.
