## Intended Use

The Oculus-SA Lumbar Cage System is intended for spinal fusion procedures at one level (L2 to S1) in skeletally mature patients with degenerative disc disease (defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies) of the non-cervical spine. Implants are intended to be implanted via an open, anterior approach and packed with bone graft. These patients should be skeletally mature and have had at least six (6) months of non-operative treatment. In addition, these patients may have up to a Grade 1 spondylolisthesis or retrolisthesis at the involved level(s). These implants are used to facilitate fusion in the lumbar spine and are placed via an anterior (ALIF) approach. Hyperlordotic implants (those with a lordotic angle greater than or equal to 20°) are indicated for use with a supplemental spinal fixation system that has been cleared by the FDA. The Oculus-SA Lumbar Cage System implants with a lordotic angle less than 20°, when used with the internal fixation screws, do not require use of supplemental fixation.

## Device Story

Oculus-SA Lumbar Cage System is a stand-alone intervertebral fusion device for anterior lumbar interbody fusion (ALIF). Device consists of PEEK or titanium alloy cage with integrated screw holes for titanium alloy screws and locking mechanisms. Surgeon implants device via open anterior approach, packing cage with bone graft to facilitate fusion. Hyperlordotic implants (≥20°) require supplemental fixation; implants <20° do not require supplemental fixation when used with internal screws. Device provides structural support to lumbar spine during fusion process. Benefits include stabilization of spinal segment in patients with degenerative disc disease.

## Clinical Evidence

Bench testing only. Testing performed per ASTM F2077-18 (static/dynamic axial compression and compressive shear) and ASTM F2267-04 (2018) (static subsidence). Results demonstrate mechanical strength sufficient for intended use.

## Technological Characteristics

Materials: PEEK (ASTM F2026) or Ti 6Al-4V ELI (ASTM F136); Tantalum markers (ASTM F560). Design: Intervertebral cage with integrated screw holes and titanium locking mechanisms. Energy: None (mechanical). Connectivity: None. Sterilization: Non-sterile, requires sterilization by user.

## 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.

Dear Mr. Wright:

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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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.

# 510(K) SUMMARY

#### DESCRIPTION OF THE DEVICE SUBJECT TO PREMARKET NOTIFICATION:

The Oculus-SA Lumbar Cage System is a stand-alone spinal intervertebral fusion device made from medical grade PEEK (polyetheretherketone) as per ASTM F2026 or Ti 6Al-4V ELI Alloy as per ASTM F136. It is provided in a variety of footprints, styles, and sizes to accommodate various patient anatomies. The PEEK cages have one radiographic marker pin made from tantalum, per ASTM F560. The implants incorporate integrated anterior screw holes to allow for placement of titanium alloy (per ASTM F136) screws. The Oculus-SA Lumbar Cage System is offered in either a three screw or four screw configuration for anterior lumbar interbody fusion procedures. Titanium alloy locking mechanisms secure the screws in place. The Oculus-SA Lumbar Cage System implants and instruments are provided non-sterile and will require sterilization prior to each use.

## INDICATIONS FOR USE

## PERFORMANCE DATA

The Oculus™-SA Lumbar Cage System has been tested in the following test modes:

- Static axial compression per ASTM F2077-18 ●
- Static compressive shear per ASTM F2077-18 ●
- Dynamic axial compression per ASTM F2077-18 ●
- Dynamic compressive shear per ASTM F2077-18 ●
- Static subsidence per ASTM F2267-04 (2018) ●

The results of this non-clinical testing show that the strength of the Oculus™-SA Lumbar Cage System is sufficient for its intended use and is substantially equivalent to legally marketed predicate devices.

#### CONCLUSION

The overall technology characteristics and mechanical performance data lead to the conclusion that the Oculus™-SA Lumbar Cage System is substantially equivalent to the predicate device.
