Device Description
The X-PAC® TLIF Expandable Posterior Cage System and X-PAC® LLIF Expandable Lateral Cage System are lumbar interbody fusion systems comprised of a cage implant and surgical instruments. The implants are used to provide structural stability in skeletally mature individuals following discectomy and are placed via a transforaminal or lateral approach. The device is available in various sizes and footprints to accommodate varying anatomy and is designed to allow for intraoperative adjustment in the height of the cage. Surfaces of the upper plate and bottom housing that contact the vertebral endplates are "toothed" to provide stability within the intervertebral space. The outer surface teeth are designed to resist expulsion in all directions. The fenestrated cage contains openings to enhance bony ingrowth and has a bulleted nose for easier entry into the disc space. The implants are manufactured from medical grade titanium alloy per ASTM F136, and ASTM F1472. The X-PAC® TLIF Expandable Posterior Cage System and X-PAC® LLIF Expandable Lateral Cage System implants are single-use, provided non-sterile, and are intended to be steam sterilized before use. The surgical instruments are designed to facilitate precise placement of the device within the intervertebral disc body, and are re-usable, provided non-sterile, and are intended to be cleaned and steam sterilized before each use.
