Intended Use

The GS Medical QUASAR Stand-alone ACIF System is indicated for use in skeletally mature patients with degenerative disc disease (DDD) of the cervical spine with accompanying radicular symptoms at one disc level. DDD is defined as discogenic pain with degeneration of the disc confirmed by patient history and radiographic studies. The GS Medical QUASAR Standalone ACIF System is used to facilitate intervertebral body fusion in the cervical spine at the C3 to C7 disc levels using autograft bone. When the GS Medical QUASAR Standalone ACIF System is used with all the titanium alloy screws for which the implant is designed it does not require supplemental fixation. When used with fewer screws the implant should be used in conjunction with supplemental fixation that has been cleared for use in the cervical spine. Patients should have at least six (6) weeks of non-operative treatment with an intervertebral cage.

Device Story

Intervertebral body fusion device; restores disc space height; provides biomechanical stability via integrated plate; eliminates need for separate anterior cervical plate when used with all specified titanium screws. Implant consists of HA PEEK OPTIMA LT1 cage body with Ti-6Al-4V titanium alloy plates and screws. Used in cervical spine surgery; implanted by surgeons. Open architecture allows packing of autograft bone. Biomechanical performance validated via static/dynamic compression, shear, torsion, expulsion, and subsidence testing.

Clinical Evidence

Bench testing only. No clinical data provided. Performance validated via ASTM F2077 (static/dynamic axial compression, shear, torsion) and ASTM F2267 (subsidence and expulsion testing).

Technological Characteristics

Materials: HA PEEK OPTIMA LT1 (cage), Ti-6Al-4V titanium alloy (plates and screws). Design: Intervertebral cage with integrated plate and supplementary fixation screws. Standards: ASTM F2077, ASTM F2267. Sterilization: Provided in both sterile and non-sterile (end-user sterilized) versions.

Indications for Use

Indicated for skeletally mature patients with cervical degenerative disc disease (DDD) and radicular symptoms at one level (C3-C7). Requires autograft bone. Contraindicated if patient has not undergone at least 6 weeks 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.

Dear Barry Sands:

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.

#### D. INDICATIONS FOR USE

The GS Medical QUASAR Standalone ACIF System is indicated for use in skeletally mature patients with degenerative disc disease (DDD) of the cervical spine with accompanying radicular symptoms at one disc level. DDD is defined as discogenic pain with degeneration of the disc confirmed by patient history and radiographic studies. The GS Medical QUASAR Standalone ACIF System is used to facilitate intervertebral body fusion in the cervical spine at the C3 to C7 disc levels using autograft bone. When the GS Medical QUASAR Standalone ACIF System is used with all the titanium alloy screws for which the implant is designed it does not require supplemental fixation. When used with fewer screws the implant should be used in conjunction with supplemental fixation that has been cleared for use in the cervical spine. Patients should have at least six (6) weeks of non-operative treatment prior to treatment with an intervertebral cage.

#### E. DEVICE DESCRIPTION

The subject device, the QUASAR Standalone ACIF System cages are designed for restoring the height of the intervertebral space after resection of the disc while also providing biomechanical stability with the addition on an integrated plate. This integrated plate allows for the user to bypass using an additional plate as seen with traditional ACIF spacers. The QUASAR Standalone ACIF System devices consist of implants available in various heights and lordotic configurations with an open architecture to accept packing of bone graft material. The supplementary fixation screws are used along with the subject device cage and plate.

The intervertebral body fusion devices are made of hydroxyapatite polyether-ether-ketone (HA PEEK OPTIMA LT1) body with Titanium alloy plates (Ti-6Al-4V) and supplementary screws made up of Titanium alloy (Ti-6Al-4V).

#### F. PERFORMANCE DATA

The worst-case cage construct of the QUASAR Standalone ACIF System underwent testing according to ASTM 2077, specifically static and dynamic axial compression testing, shear static and dynamic compression, static and dynamic torsion testing, expulsion testing, and subsidence testing according to ASTM F2267. The results met all acceptance criteria, and the subject device cage is equivalent to the primary predicate biomechanical performance.

### G. STERILITY

The subject device, QUASAR Standalone ACIF System's cage implants are provided in both nonsterile (end-user sterilized) and sterile versions.

#### H. CONCLUSION

The technological differences between the subject device and the predicate (K222041) do not raise new questions of safety and effectiveness. Any differences in technological characteristics have been tested and documented. The subject device and predicate(s) (K222041) have been determined to be equivalent in terms of indications for use, materials, performance, sterility, and biocompatibility.
