NuVasive Gets Expanded FDA Clearance For TLX Interbody System Used In TLIF

(RTTNews) - NuVasive Inc. (NUVA) announced an expanded U.S. Food and Drug Administration 510(k) clearance of the Company's TLX interbody system, used in the leading spinal fusion surgery. New clearance introduces an expandable 20 degree cage and broader indications for use, including use with allogeneic bone graft and use in additional levels of the spine.

The TLX interbody system is a market-leading solution that is inserted through a conventional transforaminal lumbar interbody fusion (TLIF) approach. NuVasive developed a minimally invasive approach for the TLIF procedure, the MAS® TLIF or Maximum Access Surgery (MAS) TLIF. Designed to be used with a minimally invasive spine surgery approach, TLX implants can be placed seamlessly into the disc space due to their low profile, bulleted design.

Prior to the expanded 510(k) clearance, TLX interbodies were available in 15 degree lordotic options and were only indicated for use with allograft. The recent clearance includes a 20 degree expandable interbody, and additional indications for use with allogeneic bone graft comprised of cancellous and/or corticocancellous bone graft to facilitate fusion.

The new indications also include use in the thoracic spine and at the thoracolumbar junction for treatment of disc degeneration disease or degenerative spondylolisthesis at one or two adjacent levels. Use of the TLX interbody system as an adjunct to fusion in patients diagnosed with multilevel degenerative scoliosis was also cleared. The TLX system's size offerings provide multiple options for varying patient size and anatomic considerations.
