Intended Use

The Interbody Cage is indicated for use with autogenous bone graft in patients with degenerative disc disease (DDD) at one or two contiguous levels from L2 to S1. These DDD patients may also have up to Grade I spondylolisthesis or retrolisthesis at the involved levels. DDD is defined as discogenic back pain with degeneration of the disc confirmed by history and radiographic studies. These patients should be skeletally mature and have had six months of non-operative treatment. These devices are intended for intervertebral body fusion, and are intended to be used with supplemental fixation instrumentation which has been cleared by the FDA for use in the lumbar spine.

Device Story

Interbody Cage; spinal implant for intervertebral body fusion. Used in lumbar spine (L2-S1) with autogenous bone graft and supplemental fixation. Available in various heights, widths, and lengths; styles include ALIF, Banana, Lateral, PLIF, and TLIF. Implanted by surgeons in clinical settings. PEEK versions include embedded tantalum pins for radiographic visualization. Device provides structural support to facilitate fusion in patients with degenerative disc disease. Benefits include stabilization of spinal segments and potential reduction of discogenic back pain.

Clinical Evidence

Bench testing only. Mechanical compression testing performed per ASTM F2077 to evaluate new material options (Vestakeep i4R PEEK and titanium alloy) and additional sizes. Testing demonstrated that new materials and sizes do not alter device performance or introduce a new worst-case compared to previously cleared predicate (K113478).

Technological Characteristics

Materials: PEEK (ASTM F2026, Zeniva ZA-500 or Vestakeep i4R) with tantalum markers (ASTM F560), or titanium alloy (ASTM F136). Geometry: various heights, widths, and lengths. Principle: intervertebral body fusion device. Connectivity: none. Software: none.

Indications for Use

Indicated for skeletally mature patients with degenerative disc disease (DDD) at one or two contiguous levels from L2 to S1, including those with up to Grade I spondylolisthesis or retrolisthesis, who have failed six months of non-operative treatment.

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.

# Purpose of the Submission

The purpose of this special 510(k) is to gain clearance for additional implant sizes and material options.

# Description of device

The Interbody Cage is offered in a variety of heights, widths, and lengths. The implants are manufactured from medical grade polyetheretherketone (PEEK) or titanium alloy. The devices are intended to be implanted either one device per level when used in the ALIF, Banana, or Lateral styles, and one or two devices per level when used in the PLIF/TLIF style.

Tantalum pins are embedded in the PEEK versions of the implants to help allow for radiographic visualization.

{4}------------------------------------------------

S1. These DDD patients may also have up to Grade I spondvlolisthesis or retrolisthesis at the involved levels. DDD is defined as discogenic back pain with degeneration of the disc confirmed by history and radiographic studies. These patients should be skeletally mature and have had six months of non-operative treatment. These devices are intended for intervertebral body fusion, and are intended to be used with supplemental fixation instrumentation which as been cleared by the FDA for use in the lumbar spine.

#### Materials

The devices are manufactured either from medical grade PEEK (ASTM F2026) with tantalum radiographic markers (ASTM F560), or from titanium alloy (ASTM F136). The specific grades of PEEK used may be either Zeniva ZA-500 (Solvay) or Vestakeep 4iR (Evonik).

#### Predicate Devices

Primary Predicate:

Eisertech, LLC PLIF Cage (k113478)

Additional Predicates:

Titan Spine Endoskeleton (k083714) Alphatec GLIF Cage (k090425)

Reference Predicates:

K7, LLC - K133126 - Lumbar Cages Cogent Spine - K132738 - Lumbar Cage DiFusion - K123969 - ALIF Cage SpineWorks - K133340 - ALIF Cage

#### Technological Characteristics

The Interbody Cage geometry is similar to that cleared in k113478. The worstcase size testing submitted as part of k113478 applies to all devices that are part of this current submission.

The main material of construction is either PEEK (ASTM F2026) or titanium allov (ASTM F136). When used, the PEEK may be either Zeniva ZA-500 supplied by Solvay Advanced Polymers, which is one of the materials approved in k113478, or Vestakeep i4R, supplied by Evonik, Inc, which is the new material option being requested.

#### Performance Data

The additional materials and sizes do not alter the performance of the device. The additional PEEK option is equivalent in mechanical properties. The devices

{5}------------------------------------------------

made from titanium alloy are substantially stronger than those made from PEEK. All additional sizes are larger in bearing footprint than the worst-case size tested for k113478. Additional testing (compression) per ASTFM F2077 verified that the addition of new materials did not introduce a new worst-case. Therefore, the subject Interbody Cage is substatially equivalent to its predicates.
