Intended Use

The SOVEREIGN™ Spinal System is indicated for use with autogenous bone graft in patients with degenerative disc disease (DDD) at one or two contiguous levels from L2 to S1. DDD is defined as discogenic back pain with degeneration of the disc confirmed by history and radiographic studies. These patients should be skeletally mature and have had six months of non-operative treatment. These implants may be implanted via a laparoscopic or an open anterior approach. The SOVEREIGN™ interbody system may be used as a stand-alone device or in conjunction with supplemental fixation. When used as a stand-alone device, the SOVEREIGN™ interbody device is intended to be used with the three titanium alloy fixed or variable angle screws. The accompanying cover plate MUST be used anytime the device is used with any number of variable angle screws. If the physician chooses to use less than three or none of the provided screws, then additional supplemental fixation for use in the lumbar spine must be used to augment stability.

Device Story

Intervertebral body fusion device; lens-shaped PEEK Optima interbody implant with tantalum radiopaque markers; titanium alloy screws for internal fixation. Implanted via laparoscopic or open anterior approach by surgeons. Device stabilizes vertebral body; prevents expulsion; interior space packed with autogenous bone graft. Fixed or variable angle screw options; cover plate required with variable angle screws to prevent backout. Stand-alone use or with supplemental fixation. Modified design features larger major diameter near screw head for interference fit. Provides mechanical stability to lumbar spine; facilitates fusion.

Clinical Evidence

No clinical data. Substantial equivalence supported by bench testing: static screw push-out, static/fatigue compression (ASTM F2077-03), static/fatigue compression-shear (ASTM F2267-04), static subsidence, and particulate analysis.

Technological Characteristics

Materials: PEEK Optima (polyetheretherketone) and titanium alloy; tantalum radiopaque markers. Design: Lens-shaped interbody implant with three screw holes. Standards: ASTM F2077-03 (compression/fatigue), ASTM F2267-04 (compression-shear/subsidence). Sterilization: Not specified. Connectivity: None.

Indications for Use

Indicated for skeletally mature patients with degenerative disc disease (DDD) at one or two contiguous levels from L2 to S1, confirmed by history and radiography, following six months 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

*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.

III. Description: The SOVEREIGN™ Spinal System is an intervertebral body fusion device with internal screw fixation. The screws protrude through the interbody portion of the device and stabilize the vertebral body while preventing expulsion of the implant is lens-shaped with three holes for placement of titanium screws. The SOVEREIGN™ Spinal System contains both a fixed and a variable angle screw option. The fixed angle screw option provides an interference fit with the PEEK interbody implant. The variable angle screw option provides a slight clearance between the PEEK interbody implant and the screw which allows for a small amount of variable screw angulation. This system is intended to be radiolucent and the interior space of the product is to be used with autogenous bone graft. The accompanying cover plate is designed to resist screw backout and must be used when the variable angle screws are implanted.

The SOVEREIGN™ Spinal System interbody device is manufactured from PEEK Optima® (polyetheretherketone) and contains tantalum radiopaque markers. The screws used with this device are manufactured from titanium alloy.

IV. Indications for Use: The SOVEREIGN™ Spinal System is indicated for use with autogenous bone graft in patients with degenerative disc disease (DDD) at one or two contiguous levels from L2 to SI. DDD is defined as discogenic back pain with degeneration of the disc confirmed by history and radiographic studies. These patients should be skeletaily mature and have had six months of non-operative treatment. These implants may be imipiante via a laparoscopic or an open anterior approach.

The SOVEREIGN™ Interbody System may be used as a stand-alone device or in conjunction with supplemental fixation.

{1}------------------------------------------------

When used as a stand-alone device, the SOVEREIGN™ interbody device is intended to be used with the three titanium alloy fixed or variable angle screws. The accompanying cover plate MUST be used anytime the device is used with any number of variable angle screws. If the physician chooses to use less than three or none of the provided screws, then additional supplemental fixation for use in the lumbar spine must be used to augment stability.

#### V. Summary of the Technological Characteristics:

The purpose of this 510(k) is to include modified screws to the SOVEREIGN™ Spinal System. The new subject, screw contains a larger major diameter near the head of the screw which will allow some interference between the screw and implant.

This system is cleared for indications from levels L2 to S1. The SOVEREIGN™ Spinal System is an intervertebral body fusion device with internal screw fixation. The SOVEREIGN™ Spinal System is manufactured from PEEK Optima® (polyetheretherketone) and contains tantalum radiopaque markers. The screws used with this device are manufactured from titanium alloy.

The subject and the predicate SOVEREIGN™ Spinal System are substantially equivalent in terms of design, material, indications for use, intended use and fundamental technology.

#### VI. · Identification of Legally Marketed Devices:

The design features, materials, and indications for use of the subject SOVEREIGN™ Spinal System fixed angle screws are substantially equivalent to the previously cleared predicate SQVEREIGN™ Spinal System (K09) 8/3 -S.E. 11/17/2009).

### VII. Discussion of the Non-clinical Testing:

1. Static Screw Push-out Testing

2. Static Compression Testing in accordance with ASTM Standard F2077-03 "Test Methods for Intervertebral Body Fusion Devices"

3. Compression Fatigue Testing in accordance with ASTM Standard F2077-03 "Test Methods for Intervertebral Body Fusion Devices"

4. Static Compression-Shear Testing in accordance with ASTM Standard F2267-04 "Standard Test Method for Measuring Load Induced Subsidence of an Intervertebral Body Fusion Device under Static Axial Compression''

5. Compression-Shear Fatigue in accordance with ASTM Standard Test Method for Measuring Load Induced Subsidence of an Intervertebral Body Fusion Device under Static Axial Compression'
