Intended Use

The SEMIALTM Spinal Implant is indicated for use to replace a vertebral body that has been resected or excised due to tumor or trauma/fracture. The device is intended for use as a vertebral body replacement in the thoracolumbar spine (from T1 to L5) and is intended for use with supplemental internal fixation. The SEMIALTM is intended to be implanted singularly. The supplemental internal fixation systems that may be used with the SEMIALTM Spinal Implant are the same as the Curved PEEK Tetris Spinal Implant and include, but are not limited to, DePuy AcroMed titanium plate or rod systems (Kaneda SR, University Plate, M2, ISOLA, VSP, Moss, TiMX, and Profile).

Device Story

SEMIAL Spinal Implant is a hollow, semi-cylindrical, slightly curved frame with tapered edges and spikes for vertebral body anchorage. Forged from radiolucent PEEK (PEEK-OPTIMA LT1) with embedded Titanium alloy (TiAl6V4) marker pins for radiographic localization. Available in various heights (9-49 mm), diameters (38-43 mm), and angles (2.5° or 5.2°) to facilitate lordosis control. Implanted by surgeons in clinical settings to replace resected or excised vertebral bodies in the thoracolumbar spine. Used in conjunction with supplemental internal fixation systems (e.g., plates or rods) to stabilize the spine. Provides structural support to the vertebral column following tumor or trauma-related resection.

Technological Characteristics

Material: PEEK-OPTIMA LT1; Marker pins: Titanium alloy (TiAl6V4) per ASTM F-136 and ISO 5832/3. Form factor: Hollow, semi-cylindrical, curved frame with spikes. Dimensions: 9-49 mm height, 38-43 mm diameter, 2.5° or 5.2° angle. Radiopaque markers for localization. Mechanical fixation via supplemental internal fixation systems.

Indications for Use

Indicated for vertebral body replacement in the thoracolumbar spine (T1-L5) following resection or excision due to tumor or trauma/fracture. Must be used with supplemental internal fixation. Implanted singularly.

Regulatory Classification

Identification

A spinal intervertebral body fixation orthosis is a device intended to be implanted made of titanium. It consists of various vertebral plates that are punched into each of a series of vertebral bodies. An eye-type screw is inserted in a hole in the center of each of the plates. A braided cable is threaded through each eye-type screw. The cable is tightened with a tension device and it is fastened or crimped at each eye-type screw. The device is used to apply force to a series of vertebrae to correct “sway back,” scoliosis (lateral curvature of the spine), or other conditions.

| Trade Name: | SEMIALTM |
| Classification<br>Name and No: | 21 CFR 888.3060 |
| Product Code: | MQP |
| Predicate Device | Curved PEEK Tetris™ cleared under K041888 on 10-Aug-2004. |
| Device Description: | The SEMIALTM Spinal implant is a hollow, semi-cylindrical form,<br>slightly curved frame with tapered edges. The upper and lower aspects<br>of the implant are open and the walls feature spikes which assist in the<br>positive anchorage and seating of the implant between the superior and<br>inferior vertebral bodies.<br><br>The frame is forged from PEEK (PEEK-OPTIMATM LT1), which is<br>radiolucent, and incorporates small Titanium alloy (TiAl6V4) marker<br>pins so the device can be located within the body. The marker pins<br>meet ASTM F-136 and ISO 5832/3.<br><br>The SEMIALTM Spinal Implant is available in a variety of sizes ranging<br>in height from 9 mm to 49 mm with a enrolling diameter of either<br>43mm or 38mm and either a 2.5° or a 5.2° angle. A list of SEMIALTM<br>sizes and model numbers maybe found in Appendix A. The provision<br>of varying heights, together with a wedge shaped option, to allow better<br>lordosis control, enables the surgeon to choose the size suited to the<br>individual pathology and anatomical condition. The SEMIALTM may be<br>implanted individually. |
| Intended Use: | The SEMIALTM Spinal Implant is indicated for use to replace a vertebral<br>body that has been resected or excised due to tumor or trauma/fracture.<br>The device is intended for use as a vertebral body replacement in the<br>thoracolumbar spine (from T1 to L5) and is intended for use with<br>supplemental internal fixation.<br><br>The SEMIALTM is intended to be implanted singularly.<br><br>The supplemental internal fixation systems that may be used with the<br>SEMIALTM Spinal Implant are the same as the Curved PEEK Tetris<br>Spinal Implant and include, but are not limited to, DePuy AcroMed |
| Statement of<br>Technological<br>Comparison | titanium plate or rod systems (Kaneda SR, University Plate, M2,<br>ISOLA, VSP, Moss, TiMX, and Profile).<br>The subject device have the following similarities:<br>The same indication for use; The same operating principle; The same basic design; The same materials; Implanted using the same surgical techniques and equipment; Used in conjunction with the same types of supplemental internal fixation systems; The same manufacturing environment; The same sterilization process; and The same packaging configurations. In summary, the SEMIALTM, as described in this submission is, in the<br>opinion of Signus GmbH, substantially equivalent to the predicate<br>device. |
| Conclusion: | The SEMIALTM as modified in this submission, is substantially<br>equivalent to the predicate device, Curved PEEK TETRISTM cleared<br>under K041888. This conclusion is based upon the similarities of the<br>devices in terms of functional design, indication for use, principles of<br>operation, materials, and performance characteristics. |
