Abstract
A pharyngeal airway having a pharyngeal wall of a patient at least partially surrounding and defining the airway is treated by selecting an implant dimensioned so as to be implanted at or beneath a mucosal layer of the pharyngeal wall and extending transverse to said wall. The implant has mechanical characteristics for the implant, at least in combination with a fibrotic tissue response induced by the implant, to stiffen said pharyngeal wall to resist radial collapse. The implant is implanted into the pharyngeal wall transverse to a longitudinal axis of the airway.
