Abstract
An expansible ear canal insert for treating TMJ disorders and headaches which acts directly on the TMJ and associated ligament and muscle structures to reduce stress and loads placed on the articulator disc located between the temporal bone and the mandible, as well as supportive muscles and ligaments near the TMJ. The insert is adapted to expand by application of body heat. In the expanded condition, the insert provides support to the TMJ and associated ligament and muscle structures.
Claims6
A prosthesis adapted to be inserted into an ear canal for supporting a joint between a mandible and a corresponding temporal bone, the ear canal having an entrance and an isthmus located at a position remote from the entrance, the prosthesis comprising:
- a deformable body formed from an open cell foam;
- said deformable body adapted to extend between the entrance and the isthmus of the ear canal;
- said deformable body being adapted to expand upon application of body heat such that said deformable body conforms in pressing relation against the walls of the ear canal and being adapted to contract upon the removal of body heat;
- wherein said deformable body includes plastic microspheres;
- wherein said microspheres are adapted to expand or contract upon application or removal of body heat;
- and
- wherein said deformable body is more rigid when said microspheres are in said expanded state than in said contracted state;
- a rigid hollow sound bore defining a sound transmission channel, said rigid hollow sound bore extending the length of said deformable body;
- said rigid hollow sound bore contoured to conform with the curvatures of the ear canal;
- and
- wherein said prosthesis is adapted to hold the ear canal in an open condition.
