The Coflex® Interlaminar Stabilization® Technology is an interlaminar functionally dynamic implant designed to impart a stabilization effect at the operative level(s) after a decompression surgery while retaining natural motion. It consists of a single, U-shaped component, fabricated from medical grade titanium alloy (Ti6Al4V, per ASTM F136 and ISO 5832-3). In clinical use, the “U” is positioned horizontally, with its apex oriented anteriorly and the two long arms of the “U” paralleling the long axis of the spinal processes. The implant bears load on interlaminar bone, and compresses upon spinal extension. The bone-facing surfaces are ridged to provide resistance to migration.
