Intended Use

The UniVise™ Spinous Process Fixation Plate is a posterior, non-pedicle supplemental fixation device intended for use at a single level in the non-cervical spine (T1-S1). It is intended for plate fixation/attachment to spinous processes for the purposes of achieving supplemental fusion in the following conditions: Degenerative disc disease (defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies); spondylolisthesis; trauma (i.e. fracture or dislocation); and/or tumor. The UniVise™ Spinous Process Fixation Plate is intended for use with bone graft and is not intended for stand alone use

Device Story

UniVise™ Spinous Process Fixation Plate is a one-piece bilateral locking plate; attaches to posterior non-cervical spine by grasping adjacent spinous processes. Used as supplemental fixation in interbody fusion procedures. Implanted via conventional or minimally-invasive surgical methods using proprietary manual instrumentation. Surgeon operates device to provide stability during fusion. Benefits patient by providing supplemental fixation for spinal conditions; not intended for stand-alone use.

Clinical Evidence

No clinical data generated for this submission. Device design is identical to the predicate VertiFlex® Spinous Process Fixation Plate (K122509).

Technological Characteristics

One-piece bilateral locking plate; material: titanium 6Al-4V alloy. Designed for posterior non-cervical spine fixation. Manual instrumentation used for implantation. No software or electronic components.

Indications for Use

Indicated for patients requiring supplemental fusion at a single level in the non-cervical spine (T1-S1) for degenerative disc disease, spondylolisthesis, trauma (fracture/dislocation), or tumor. Not for stand-alone use; must be used with bone graft.

Regulatory Classification

Identification

A spinal interlaminal fixation orthosis is a device intended to be implanted made of an alloy, such as stainless steel, that consists of various hooks and a posteriorly placed compression or distraction rod. The device is implanted, usually across three adjacent vertebrae, to straighten and immobilize the spine to allow bone grafts to unite and fuse the vertebrae together. The device is used primarily in the treatment of scoliosis (a lateral curvature of the spine), but it also may be used in the treatment of fracture or dislocation of the spine, grades 3 and 4 of spondylolisthesis (a dislocation of the spinal column), and lower back syndrome.

Predicate Devices

• Affix® Spinous Process Plate System (K131238)
• VertiFlex® Spinous Fixation Plate (K122509)

| Classification Name<br>and Number | Spinal interlaminal fixation orthosis, 21 C.F.R. 888.3050 |
| Product Code | PEK |
| Predicate Devices | The UniVise™ Spinous Process Fixation Plate was shown to be<br>substantially equivalent to the devices listed below:<br>• Affix® Spinous Process Plate System, NuVasive Incorporated,<br>K131238<br>• VertiFlex® Spinous Fixation Plate, VertiFlex Incorporated,<br>K122509 |
| Device Description | The UniVise™ Spinous Process Fixation Plate is a one-piece bilateral<br>locking plate device which attaches to the posterior non-cervical spine<br>by securely grasping two adjacent spinous processes. The S.P.F.P is<br>available in multiple sizes to accommodate different anatomical<br>requirements, and it is composed entirely of titanium 6Al-4V alloy. The<br>UniVise™ Spinous Process Fixation Plate may be implanted by either<br>conventional surgical methods, or via minimally-invasive techniques.<br>Proprietary manual instrumentation for implantation of the S.P.F.P is<br>available for both conventional and minimally-invasive surgical<br>procedures. When the UniVise™ Spinous Process Fixation Plate is used<br>as supplemental fixation in interbody fusion procedures, its use is<br>limited to the treatment of degenerative disc disease (DDD) of the<br>lumbosacral spine (L2-S1). |
| Intended Use | The UniVise™ Spinous Process Fixation Plate is a posterior, non-<br>pedicle supplemental fixation device intended for use at a single level in<br>the non-cervical spine (T1-S1).

| Summary of the Technological<br>Characteristics | As was established in this submission, the UniVise™ Spinous<br>Process Fixation Plate is substantially equivalent and has<br>equivalent technological characteristics to other predicate<br>devices cleared by the FDA as demonstrated through<br>comparison in areas such as design, labeling, intended use,<br>material composition, and function. |
|-------------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| Summary of the Performance<br>Data | The purpose of this 510(k) is to modify the Surgical<br>Technique for the subject UniVise™ Spinous Process<br>Fixation Plate. No device design changes have been made to<br>the predicate VertiFlex® Spinous Process Fixation Plate<br>(commercially distributed as the UniVise™ Spinous Process<br>Fixation Plate by Stryker Spine) previously cleared in<br>K122509. No new performance data was generated for the<br>purpose of this submission. |
| Conclusions | The UniVise™ Spinous Process Fixation Plate is as safe and<br>effective as the predicate devices as it has the same intended<br>uses and similar indications for use, technological<br>characteristics, and principles of operation as its predicate<br>devices. |
