Indications for Use

Zeus Small Cervical Cages are 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. Zeus Cervical Cages are used to facilitate intervertebral body fusion in the cervical spine and are placed via an anterior approach at the C3 to C7 disc levels using autograft bone. Zeus Cervical Cages are to be used with supplemental fixation. Patients should have at least six (6) weeks of non-operative treatment prior to treatment with an intervertebral cage. The Zeus Lumbar Cages are indicated for intervertebral body spinal fusion procedures in skeletally mature patients with degenerative disc disease (DDD) at one level from 12-51. DDD is defined as discogenic back pain with degeneration of the disc confirmed by patient history and radiographic studies. These DDD patients may also have up to Grade I spondylolisthesis at the involved level. Zeus implants are to be used with autogenous bone graft and implanted via an anterior/transforaminal/posterior approach. The Zeus Lumbar Cages are to be used with supplemental fixation. Patients should have at least six (6) months of non-operative treatment prior to treatment with an intervertebral cage.

Device Story

Zeus Intervertebral Fusion Devices consist of PEEK-OPTIMA LT1 polymer cages designed for spinal fusion. Cervical cages are trapezoidal with a central window; lumbar cages (Anterior, Curved/T-LIF, Straight/PLIF) feature surface ridges to prevent migration and large windows for bone graft integration. Implants are placed surgically by physicians to stabilize the spinal column and facilitate fusion. Devices are used with autogenous bone graft and supplemental fixation. Benefit includes stabilization of the spinal segment and promotion of bony fusion in patients with degenerative disc disease.

Clinical Evidence

Bench testing only. Mechanical strength testing performed in accordance with ASTM F2077 and ASTM F2267 standards to verify performance requirements.

Technological Characteristics

Materials: PEEK-OPTIMA LT1 polymer (ASTM F2026). Design: Trapezoidal (cervical) or rectangular/curved (lumbar) cages with graft windows and surface ridges. Energy source: None (passive implant). Sterilization: Not specified. Connectivity: None.

Indications for Use

Indicated for skeletally mature patients with degenerative disc disease (DDD) at one level (cervical C3-C7 or lumbar L2-S1). Lumbar patients may have up to Grade I spondylolisthesis or retrolisthesis. Requires autograft/autogenous bone graft and supplemental fixation. Contraindicated for patients without prior non-operative treatment (6 weeks for cervical, 6 months for lumbar).

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.

#### ന Predicate or legally marketed devices which are substantially equivalent:

The Interbody Innovations Zeus Intervertebral Fusion Devices are substantially equivalent to similar previously cleared cervical and lumbar intervertebral body fusion devices.

#### 4. Description of the device:

The Zeus Small Cervical Cage was developed as an intercorporal implant for anterior cervical spondylodesis. The top view is trapezoidal with a trapezoidal window for bone graft. The Zeus Cervical Cage has a flat top and bottom.

The Zeus Large/Extra Large Lumbar Cage was developed as an implant for the posterior stabilization of the lumbar spinal column using an Anterior Lumbar Interbody Fusion (ALIF) technique. To eliminate migration, ridges are incorporated on both the superior and inferior surfaces. Two large windows allow bony growth to form.

The Zeus Curved Large Lumbar Cage was developed as an implant for the posterior stabilization of the lumbar spinal column using a Transforaminal Lumbar Interbody Fusion (T-LIF) technique. The Zeus Curved implant has ridges on both its inferior and superior surfaces to prevent migration, and two large graft windows which help facilitate bony integration. It is a curved shape to facilitate insertion using a T-LF approach.

The Zeus Straight Lumbar Cage was developed as an implant for the posterior stabilization of the lumbar spinal column using a Posterior Lumbar Interbody Fusion (PLIF) technique and is used in pairs. The Zeus Straight implant incorporates ridges on both its superior and inferior surfaces to help eliminate migration. A large rectangular graft space help facilitate bony integration once implanted..

### Materials:

PEEK-OPTIMA LT1 polymer (ASTM F2026 Standard Specification for Polyetheretherketone (PEEK) Polymers for Surgical Implant Applications)

### 5. Intended Use:

Zeus Small Cervical Cage s are 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. Zeus Cervical Cages are used to facilitate intervertebral body fusion in the cervical spine and are placed via an anterior approach at the C3 to C7 disc levels using autograft bone. Zeus Cervical Cages are to be used with supplemental fixation. Patients should have at least six (6) weeks of non-operative treatment prior to treatment with an intervertebral cage.

The Zeus Lumbar Cages are indicated for intervertebral body spinal fusion procedures in skeletally mature patients with degenerative disc disease (DDD) at one level from 12-51. DDD is defined as discogenic back pain with degeneration of the disc confirmed by patient history and radiographic studies. These DDD patients may also have up to Grade I spondylolisthesis at the involved level. Zeus implants are to be used with autogenous bone graft and implanted via an anterior/transforaminal/posterior approach. The Zeus Lumbar Cages are to be used with supplemental fixation. Patients should have at least six (6) months of non-operative treatment prior to treatment with an intervertebral cage.

- Comparison of the technological characteristics of the device to predicate and legally marketed devices: 6. The Interbody Innovations Zeus Intervertebral Fusion Devices have indications and material, and similar designs as previously cleared devices.
#### 7. Summary of Non-clinical Tests

Tests performed according to ASTM F2077/F2267 indicate that the Interbody Zeus Innovations Intervertebral Fusion Devices meet required mechanical strengths. Some of the predicate devices have a different geometry than the Interbody Innovations Zeus Intervertebral Fusion Devices and do not have some test results reported in their PMA summaries, therefore, additional acceptance values for testing have been utilized.
