Methods and devices comprised of a collapsible insert member and shaping member for treating obstructive sleep apnea are described. The insert member is placed in the tongue or other tissue forming the airway of the patient and has a lumen to accommodate the shaping member. The shaping member is inserted into the insert member by the patient just prior to sleep and removed upon waking. A variety of shaping members are available to treat patients on an individual basis, i.e., to match their particular anatomic condition that is causing their apnea or snoring. The shaping member can be made from nitinol, stainless steel, or any other known biocompatible implant material capable of providing a change in the tissue response to stress.
