Intended Use

CAVUX™ Cervical Cage is indicated for use in skeletally mature patients with degenerative disc disease (DDD) of the cervical spine (C3-C7) with accompanying radicular symptoms at one disc level. DDD is defined as discogenc pain with degeneration of the disc confirmed by patient history and radiographic studies. Patients should have received at least six weeks of non-operative treatment with the device. Devices are intended to be used with autogenous bone graft and supplemental fixation, such as an anterior plating system.

Device Story

CAVUX™ Cervical Cage is an intervertebral body fusion device; implanted into cervical spine (C3-C7) to treat degenerative disc disease. Device is hollow, titanium alloy (6AI4V-ELI) cage; filled with autogenous bone graft; features fenestrations (windows) for bone visualization and growth. Implanted via delivery instrument with physical stop to prevent over-insertion. Used by surgeons in clinical settings; requires supplemental fixation (e.g., anterior plating system). Provides structural support to interbody space; promotes fusion; benefits patients by stabilizing spine and reducing discogenic pain.

Clinical Evidence

Bench testing only. Performed static/dynamic axial compression, static/dynamic torsion, subsidence, and expulsion testing per ASTM F2077-14, ASTM F2267-04, and draft ASTM F-04.25.02.02. Pyrogenicity testing conducted per FDA guidance. Results met all acceptance criteria and exceeded predicate device performance.

Technological Characteristics

Material: Titanium-6AL-4V ELI alloy (ASTM F136). Design: Hollow cage with fenestrations; superior/inferior surfaces feature teeth, grit blasting, and acid etching. Delivery: Includes delivery instrument with physical stop. Sterilization: Sterile, single-use. Connectivity: None.

Indications for Use

Indicated for skeletally mature patients with degenerative disc disease (DDD) of the cervical spine (C3-C7) with radicular symptoms at one level, following at least six weeks of failed 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

#### Device Description:

The CAVUX™ Cervical Cage is a cervical intervertebral body fusion device. The system is comprised of a variety of implant sizes to accommodate various patient anatomies and pathology. All implantable components are manufactured from medical grade titanium alloy (6AI4V —ELI Ti). The center of the implant is hollow and is to be filled with autogenous bone material. The design incorporates "windows" through the implant to permit visualization of the graft material and, over time, formation of new bone.

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

#### Indications for Use:

CAVUX™ Cervical Cage is indicated for use in skeletally mature patients with degenerative disc disease (DDD) of the cervical spine (C3-C7) 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. Patients should have received at least six weeks of non-operative treatment prior to treatment with the device. Devices are intended to be used with autogenous bone graft and supplemental fixation, such as an anterior plating system.

#### Technological Characteristics:

The CAVUX™ Cervical Cage consists of the following:

- CAVUX™ Cervical Cage Implant .
- . Delivery Instrument packaged with the Implant

The CAVUX™ Cervical Cage implants are manufactured from Titanium-6AL-4V ELI alloy, which conforms to ASTM F136 and are available in a variety of sizes and lordotic angles to accommodate patient anatomy. Superior and inferior surfaces of the implant feature teeth that provide bony contact with the endplates while a box shape in the center of the implant with fenestrations (windows) is intended to house autogenous bone. The superior and inferior surfaces of the implant are grit blasted and acid etched to improve fixation to adjacent bone.

The CAVUX™ Cervical Cage is held within the delivery instrument which facilitates insertion of the implant into the interbody space. The delivery instrument features a physical stop to prevent over-insertion.

Devices are supplied sterile and single use only.

#### Performance Testing

The following testing was performed using the subject device and results were compared to those of the predicate device:

#### Static and Dynamic Axial Compression Testing

- ASTM F2077-14 Standard Test methods for Intervertebral Body Fusion Devices .
#### Static and Dynamic Torsion Testing

- ASTM F2077-14 Standard Test methods for Intervertebral Body Fusion Devices .
#### Subsidence Testing

- . ASTM F2267-04 Standard Test Method for Measuring Load Induced Subsidence of Intervertebral Body Fusion Device Under Static Axial Compression

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

#### Expulsion Testing

- ASTM Draft Standard F-04.25.02.02 Static Push-out Test Method for Intervertebral . Body Fusion Devices
### Pyrogenicity Testing

- . Pyrogenicity Testing was conducted and in compliance with FDA Guidance Documents listed below:
- "Submission and Review of Sterility Information in Premarket Notification o (510(k)) Submissions for Devices Labeled as Sterile: Guidance for Industry and Food and Drug Administration Staff"
- "Pyrogen and Endotoxins Testing: Questions and Answers" O

In all instances, the CAVUX™ Cervical Cage functioned as intended and met all pre-determined acceptance criteria. Bench testing results of the CAVUX™ Cervical Cage exceeded those of the predicate PMT Cervical Cage. Therefore, the performance characteristics of the CAVUX ™ Cervical Cage are substantially equivalent to those of the PMT Cervical Cage.

#### Conclusions

The CAVUX™ Cervical Cage has the same indication for use, technological characteristics, and principles of operation as the predicate device. The differences between the subject and predicate devices are that the subject device includes a surface treatment and is available in different sizes than the predicate device. These minor differences between the CAVUX™ Cervical Cage and its predicate device raise no new issues of safety or effectiveness. Performance data demonstrate that the CAVUX™ Cervical Cage is as safe and effective as the PMT Cervical Cage. Thus, the CAVUX™ Cervical Cage is substantially equivalent to the PMT Cervical Cage.
