Intended Use

The Endoskeleton™ TA Interbody System devices including those with macro-, micro- and nano-roughened surface textured features are indicated for use in skeletally mature patients with Degenerative Disc Disease (DDD, defined as discogenic back pain with degeneration of the disc confirmed by patient history and radiographic studies), degenerative spondylolisthesis, and/or spinal stenosis at one or two contiguous levels from L2-S1 whose condition requires the use of interbody fusion. Patients should have received 6 months of non-operative treatment with the devices. The Endoskeleton™ TA Interbody System implants can also be used as an adjunct to fusion in patients diagnosed with multilevel degenerative scolosis and sagittal deformity. The device is to be used with supplemental fixation cleared by the FDA for use in the lumbar spine. These patients may also have up to Grade I spondylolisthesis at the involved level(s). Endoskeleton™ TA Interbody System is indicated to be used with autograft bone comprised of cancellous and/or corticocancellous bone, demineralized allograft with bone marrow aspirate, or a combination thereof.

Device Story

Intervertebral body fusion devices; hollow titanium cages designed to house bone graft; promote spinal fusion; stabilize disc space. Features Titan Surface Technologies™ (macro-, micro-, nano-roughened surfaces); nanoLOCK™ surface technology utilizes nanometer-scale features to elicit endogenous cellular/biochemical response. Implanted by surgeons in spinal fusion procedures. Provides structural support; facilitates bone ingrowth. Used in lumbar (L2-S1) or cervical (C2-T1) spine. Some models include integrated fixation screws; others require supplemental internal spinal fixation (e.g., pedicle screws).

Clinical Evidence

Bench testing only. No clinical data provided. Substantial equivalence established through comparison of design, materials, and intended use to previously cleared predicate devices.

Technological Characteristics

Materials: ASTM F136 Ti 6Al-4V ELI titanium alloy; ASTM F3001 additive manufactured Ti 6Al-4V ELI. Surface: Titan Surface Technologies™ (Chemtex™ or nanoLOCK™). Principle: Intervertebral body fusion via structural cage and bone graft. Form factor: Various sizes with hollow center and visualization windows. Sterilization: Sterile or non-sterile.

Indications for Use

Indicated for skeletally mature patients with DDD, degenerative spondylolisthesis, or spinal stenosis requiring interbody fusion at L2-S1 (lumbar) or C2-T1 (cervical). Patients must have failed 6 months of non-operative treatment. Used with autograft/allograft bone. Requires supplemental fixation (except specific standalone configurations).

Regulatory Classification

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.

IV. The Endoskeleton™ Interbody System implants are available in a Description: variety of sizes and designed with a large hollow region in the center to house autograft bone, allograft bone comprised of cancellous and/or corticocancellous bone, demineralized allograft with bone marrow aspirate, or a combination thereof. The design incorporates "windows" through the implant to permit visualization of the graft material and, over time, formation of new bone. Devices incorporate Titan Surface Technologies™, where superior and inferior surfaces include either Chemtex™ or nanoLOCK™ surface treatment (MMN™) designed to improve fixation to adjacent bone. nanoLOCK™ surface technology (MMN™) provides a microscopic roughened surface with nanoscale features. The nanoLOCK™ Surface Technology is specifically engineered to have nano textured features at a nanometer (10°) level, which have demonstrated the ability to elicit an endogenous cellular and biochemical response attributed to these nanotextured features in vitro. The nanoLOCK™ surface technology demonstrates the elements to be considered a nanotechnology as outlined in the FDA nanotechnology guidance document. New bone formation through the implant is intended to provide long-term structural support and fusion at the implanted disc space. Implants are composed of ASTM F136 Ti 6Al-4V ELI titanium alloy and are provided either sterile or non-sterile. The Endoskeleton™ TL Hyp. implants are composed of ASTM F3001 Ti 6Al-4V ELI titanium alloy and are provided sterile. The Endoskeleton™ TAS & TAS Hyp. and Endoskeleton™ TCS Interbody systems include integrated fixation screws for stabilizing the implants when placed in the interbody space. Screws are composed of ASTM F136 Ti 6Al-4V ELI titanium alloy and are provided either sterile or nonsterile. {12}------------------------------------------------ The Endoskeleton™ Interbody System implants should only be implanted by surgeons experienced in the use of such implants and the required specialized spinal surgery techniques. #### V.

Comparison of The subject Endoskeleton™ Interbody System implants have the same Technological intended use, fundamental scientific technology, material, sizing, and {16}------------------------------------------------ Characteristics sterilization method as the previously FDA cleared Endoskeleton™ with the Interbody System predicates. The primary difference between Predicate predicate devices and subject devices are: - Devices . The modification to the device description to identify the devices with nanoLOCK™ Surface Technology meet the FDA guidance document definition of nanotechnology. - The modification to indications to identify that the devices treat instability of the spine through spinal fusion. - The expansion of indications based on the predicates' cleared indications for EIT Cellular Titanium® Cages- K201605 (S.E. 07/15/2020) and NuVasive Interbody Systems K203201 (S.E. 01/12/2021). Please refer to the substantial equivalence section of this submission for more details. Both Subject and Predicate devices are based on the same technological characteristics of providing vertebral stability through fusion for skeletally mature patients with degenerative disc disease (DDD - defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies), degenerative spondylolisthesis, and/or spinal stenosis where the instability requires treatment through spinal fusion. The indications for use are substantially equivalent to the EIT Cellular Titanium® Cages K201605 (S.E. 07/15/2020) and the NuVasive Interbody Systems K203201 (S.E. 01/12/2021). The design features, materials and intended use of the subject devices are substantially equivalent to the previously cleared predicate Endoskeleton™ Interbody Fusion Systems K192018 (S.E. 08/13/2019). Therefore, the technological characteristics of the subject devices are identical to the predicate devices. {17}------------------------------------------------ #### VII. Performance Mechanical Testing: #### Data In accordance with, "Guidance for Industry and FDA Staff – Spinal System 510(k)'s", Medtronic has evaluated the subject devices to demonstrate substantial equivalence to the predicate devices.
