Intended Use

The TiBow™ Expandable Spacer System is intended for spinal fusion procedures in skeletally mature patients with degenerative disc disease (DDD) at one or two contiguous levels (L2-S1). DDD is defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies. DDD patients may also have up to Grade 1 spondylolisthesis at the involved level(s). It is to be used in patients who have had at least six months of nonoperative treatment. This device is intended to be used with autogenous bone graft and a supplemental internal spinal fixation system (e.g., pedicle screw or anterolateral plating system) that is cleared for use in the lumbosacral spine.

Device Story

Intervertebral body fusion device; used in spinal fusion procedures. Implant features expandable mechanism for in situ footprint adjustment; hollow design for autogenous bone graft packing; superior/inferior teeth for endplate fixation. Fabricated from titanium alloy. Used in lumbosacral spine; requires supplemental internal fixation (e.g., pedicle screws). Surgeon-operated; provides structural support to facilitate fusion in patients with degenerative disc disease.

Clinical Evidence

Bench testing only. Performance data included static compression, dynamic compression, and shear testing per ASTM F2077, alongside Finite Element Analysis.

Technological Characteristics

Titanium alloy (Ti-6Al-4V ELI) per ASTM F136. Expandable intervertebral spacer; hollow geometry for bone graft; serrated superior/inferior surfaces. Mechanical testing per ASTM F2077.

Indications for Use

Indicated for skeletally mature patients with degenerative disc disease (DDD) at one or two contiguous levels (L2-S1), including those with up to Grade 1 spondylolisthesis, who have failed at least six months of nonoperative 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.

Dear Mr. 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). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting (reporting of medical device

#### Device Description:

The TiBow™ Expandable Spacer System is intended to serve as an intervertebral body fusion device. The implant is available in a range of sizes and footprints to suit the individual pathology and anatomical conditions of the patient. It is fabricated and manufactured from titanium alloy (Ti-6Al-4V ELI) as described by ASTM F136. The device contains an expandable mechanism that allows it to achieve its final footprint in situ. The implant is hollow to permit packing with autogenous bone graft to help promote intervertebral body fusion. The superior and inferior surfaces have teeth to assist in the interface with the vertebral endplates to prevent rotation and/or migration.

#### Technological Characteristics:

The TiBow™ Expandable Spacer System is substantially equivalent to the predicate systems in terms of design, materials, indications for use and sizing.

#### Performance Data:

Static compression, dynamic compression and shear testing in accordance with ASTM F2077, in addition to Finite Element Analysis and engineering rationale, was presented to demonstrate the substantial equivalency of The TiBow™ Expandable Spacer System.

#### Conclusions:

The TiBow™ Expandable Spacer System was shown to be substantially equivalent to the predicate devices in indications for use, design, function, materials used and mechanical performance.
