Vertera Spine announced first implantations with the COHERE™ Cervical Interbody Fusion System, which features porous PEEK Scoria™ biomaterial. COHERE is reportedly the first device in clinical use to be manufactured entirely out of PEEK and contain porosity.
The COHERE system received FDA 510(k) clearance to market in early 4Q15. Full market launch is slated for coming months.
Scoria is designed to grow directly from the solid PEEK Zeniva material, creating a seamless surface-to-solid material interface that is more durable than metal coatings and 2x stronger under shear loading than trabecular bone. Further, Scoria can be fabricated onto the device without additive material; thus, implants with this porous technology may be priced competitively against current PEEK device offerings and may be more cost effective than titanium-coated fusion devices.
Other companies addressing surface technologies for spine are shared in the BONEZONE article, "Materials in Motion."
