1. A method for supporting or reshaping a palatopharyngeal muscle with a device, wherein the device comprises a central load bearing section having a first end and a second end, a first filament section having a first free end and a second end connected to the first end of the load bearing section, and a second filament section having a first free end and a second end connected to the second end of the load bearing section comprising the steps of:
- a) passing the free end of the first filament section in a first direction leaving the load bearing section around the palatopharyngeal muscle and into a first supporting tissue;
b) passing the free end of the second filament section into tissue in a different direction from the first direction and into a second supporting tissue while maintaining the load bearing section around the palatopharyngeal muscle wherein the passing of the filaments follow a helical path; and
c) applying tension to the free ends of the first and second filament sections to sufficiently support or reshape the palatopharyngeal muscle to achieve multi-vector retraction.

Abstract
Obstructive Sleep Apnea (OSA) may be caused by a collapse of the pharyngeal wall as a result of increasing negative airway pressure. This invention is directed to systems and methods to resist collapse of the pharyngeal wall by minimally invasive upper pharyngeal airway surgery.

8. A method for increasing a patency of an airway of a patient, the airway comprising palatopharyngeal muscles and palatoglossal muscles, the method comprising the step of retracting or supporting one or both of the palatopharyngeal muscles, wherein the step of retracting or supporting the palatopharyngeal muscle(s) comprises:
-
a) piercing at least one of the palatopharyngeal muscles at a point with a device comprising a filament extending from a tab wherein the filament pierces at least one of the palatopharyngeal muscles; b) drawing the filament through the at least one palatopharyngeal muscle until the tab rests at the point where the palatopharyngeal muscle had been pierced wherein the drawing of the filament follows a helical path; and c) applying tension to the filament to retract or support the at least one of the palatopharyngeal muscles. - View Dependent Claims (9, 10)
