The system is designed for use with autogenous bone graft to facilitate fusion. The NuVasive MLX - Medial Lateral Expandable Lumbar Interbody System is intended for use at either one level or two contiguous levels in the lumbar spine, from L2 to S1, for the treatment of degenerative disc disease (DDD) with up to Grade I spondvlolisthesis. DDD is defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies. Patients must have undergone a regimen of at least six (6) months of non-operative treatment prior to being treated with the NuVasive MLX - Medial Lateral Expandable Lumbar Interbody System. The NuVasive MLX - Medial Lateral Expandable Lumbar Interbody System is intended to be used with supplemental internal spinal fixation systems that are cleared by the FDA for use in the lumbar spine. ## Device Story Expandable lumbar interbody fusion device; implanted surgically to facilitate spinal fusion in patients with degenerative disc disease. Device provides structural support between vertebrae; used with autogenous bone graft and supplemental internal fixation. Manufactured from Ti-6Al-4V ELI (ASTM F136/ISO 5832-3), Ti-6Al-4V (ASTM 1472), Nitinol SE508 (ASTM F2063), and MP35N (ASTM F562). Available in various shapes/sizes to accommodate patient anatomy. Device is a mechanical implant; no electronic or software components. ## Clinical Evidence Bench testing only. Evidence includes Finite Element Analysis (FEA), anterior shear impact testing, and torsional separation testing to demonstrate mechanical equivalence to predicate devices. ## Technological Characteristics Materials: Ti-6Al-4V ELI (ASTM F136, ISO 5832-3), Ti-6Al-4V (ASTM 1472), Nitinol SE508 (ASTM F2063), and MP35N (ASTM F562). Expandable interbody fusion cage. Mechanical device; no energy source, connectivity, or software. ## Regulatory Identification An intervertebral body fusion device is an implanted single or multiple component spinal device made from a variety of materials, including titanium and polymers. The device is inserted into the intervertebral body space of the cervical or lumbosacral spine, and is intended for intervertebral body fusion. ## Special Controls *Classification.* (1) Class II (special controls) for intervertebral body fusion devices that contain bone grafting material. The special control is the FDA guidance document entitled “Class II Special Controls Guidance Document: Intervertebral Body Fusion Device.” See § 888.1(e) for the availability of this guidance document.(2) Class III (premarket approval) for intervertebral body fusion devices that include any therapeutic biologic (e.g., bone morphogenic protein). Intervertebral body fusion devices that contain any therapeutic biologic require premarket approval. (c) *Date premarket approval application (PMA) or notice of product development protocol (PDP) is required.* Devices described in paragraph (b)(2) of this section shall have an approved PMA or a declared completed PDP in effect before being placed in commercial distribution. ## Predicate Devices - NuVasive® Expandable Lumbar Interbody System ([K130820](/device/K130820.md)) - NuVasive® CoRoent® Titanium System ([K120918](/device/K120918.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Technological Characteristics As was established in this submission, the subject NuVasive MLX - Medial Lateral Expandable Lumbar Interbody System is substantially equivalent to other predicate devices cleared by the FDA for commercial distribution in the United States. The subject device was shown to be substantially equivalent and have the same technological characteristics to its predicate devices through comparison in areas including design, intended use, material composition, and function. ### G. Performance Data Finite Element Analysis (FEA), anterior shear impact testing, torsional separation testing and engineering rationale was provided as the evidence that modified design of the MLX System device does not create new worst case for performance testing. Therefore, the subject device was found to be substantially equivalent to the predicates. #### H. Conclusions Based on the indications for use, technological characteristics, and comparison to predicate devices, the subject NuVasive MLX – Medial Lateral Expandable Lumbar Interbody System has been shown to be substantially equivalent to legally marketed predicate devices. {2}------------------------------------------------ ### DEPARTMENT OF HEALTH & HUMAN SERVICES Public Health Service Food and Drug Administration 10903 New Hampshire Avenue Document Control Center - WO66-G609 Silver Spring, MD 20993-0002 July 25, 2014 Nuvasive, Incorporated Ms. Olga Lewis Regulatory Affairs Specialist 7475 Lusk Boulevard San Diego, California 92121 Re: K140770 Trade/Device Name: NuVasive® MLX™ - Medial Lateral Expandable Lumbar Interbody System Regulation Number: 21 CFR 888,3080 Regulation Name: Intervertebral body fusion device Regulatory Class: Class II Product Code: MAX Dated: June 20, 2014 Received: June 23, 2014 Dear Ms. Lewis: We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA).
