Xtant Medical's Irix-A is a standalone interbody device used in anterior lumber interbody fusions. The current product line offers a titanium and PEEK composite implant, with the additional option of a titanium plasma coating for improved osseointegration with the spinal endplate, all with 8 degrees or 12 degrees of lordosis for alignment with the curvature of the spine. This new 510k clearance adds three additional degrees of lordosis, specifically 16 degrees, 20 degrees, and 24 degrees, providing the surgeon with a wider variety of choices to correct the patient's loss of lordosis and to improve sagittal balance. The FDA clearance also expands the indications of use to include use with allograft, such as Xtant Medical's patented OsteoSponge, proprietary 3Demin, or OsteoVive viable cell allograft.
"The clearance of the additional footprints, including hyperlordotic options, further enhances our lumbar product portfolio in response to our customer's needs," said Gregory Juda, chief scientific officer. "We continue to execute on our focus of combining our hardware and biologics technologies, strengthening our position as a comprehensive supplier for spine surgeons and their patients."
The Irix-A Lumbar Integrated Fusion System consists of an integrated titanium ring, surrounded by an outer PEEK ring and three screws. It is intended for anterior spinal fusion procedures at one or two contiguous levels of the lumbosacral spine (L2-S1 inclusive) in skeletally mature patients for the treatment of degenerative disc disease.
Xtant Medical estimates the U.S. market for standalone anterior lumbar interbody fusion market to be approximately $230 million and growing. The U.S. market for demineralized bone matrix (DBM) is estimated at $410 million. The additional Irix-A interbody implants are intended to be available to customers later this year.
