Patent ID: 8469908

Claim:
An analgesic implant system for imparting vibratory massage to a bone tissue, the system comprising: an implant device configured to produce and communicate a vibration to the bone tissue, the implant device including: a case forming at least a portion of an exterior of the implant device and defining an interior of the implant device, the case having an exterior surface, the exterior surface having an elongated shape with a longitudinal axis and a first end and a second end; a vibration generator mounted on the case and configured to vibrate the at least portion of the exterior of the implant device; a tissue engaging structure located on the exterior surface of the case and configured to secure the case on the bone tissue; a first bearing structure comprising a first bearing surface configured to bear against a side of a spinous process; and a second bearing structure comprising a second bearing surface configured to bear against an opposite side of the spinous process; wherein the second bearing structure has an aperture therein configured to receive the case therein; and wherein the tissue engaging structure includes at least one helical ridge formed on the exterior surface of the case; and wherein the aperture of the second bearing structure is defined by an aperture surface, the aperture surface being generally cylindrical and including at least one helical groove formed therein complementary to the at least one ridge of the exterior surface of the case such that rotation of the second bearing structure in a first direction mounts the second bearing structure on the case and rotation of the second bearing structure in a second direction dismounts the second bearing structure from the case.
