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.

# Substantial Equivalence:

The proposed modifications to the Endoskeleton® devices are identical to predicate devices previously cleared by Titan Spine:

- Predicate: Endoskeleton TAS K111626 .
- . Other predicates: Endoskeleton TA - K080615, Endoskeleton TT - K083714, Endoskeleton TO - K102067, Endoskeleton TC - K100889, Endoskeleton TL -K140055 and Endoskeleton TA VBR - K032812

{8}------------------------------------------------

The subject Endoskeleton® device is identical to the predicate devices with respect to indications for use, design, dimension, and materials. The only difference to the currently marketed devices is the change in surface treatment.

# Technological Characteristics

There are no changes between the predicate devices and the subject devices with respect to indications for use, design, dimension, and materials. The only difference to the currently marketed devices is the change in surface treatment. There are additional processing steps for the new surface treatment when compared to the previous surface treatment.

# Performance Testing:

Mechanical testing was performed to establish mechanical strength of the devices (ASTM F2077). Surface specific characterization and integrity testing were completed to support biocompatibility through ISO 10993-1. Pre-clinical testing performed included axial fatigue testing per ASTM F2077. Additionally, wear testing was done using a modified protocol of ASTM F1160 with particulate characterization. Biocompatibility per ISO 10993 was established through ISO 10993-1 assessment and an implantation animal model. The testing indicated that the Endoskeleton® devices are adequate for the intended use and substantially equivalent to the predicate systems.
