TEMPUS CERVICAL PLATE SYSTEM

{0}------------------------------------------------ # 5.510(K) Summary | Submitter's Name: | NeuroStructures, LLC | |----------------------------|-----------------------------------------------------------------------------------------------------------------------------| | Submitter's Address: | 63 Bovet Road, Suite 135<br>San Mateo, CA 94402 | | Submitter's Telephone: | 800-352-6103 | | Contact Name: | John Stephani | | Date Summary was Prepared: | 02/16/2012 | | Trade or Proprietary Name: | Tempus™ Cervical Plate System | | Common or Usual Name: | Spinal intervertebral body fixation orthosis | | Classification: | Class II per 21 CFR §888.3060 | | Product Code: | KWQ | | Classification Panel: | Orthopedic and Rehabilitation Devices Panel | | Predicate Devices: | Synthes CSLP Cervical Plate (K030866)<br>Centerpulse Spine-Tech Trinica Select™ Anterior Cervical Plate<br>System (K012305) | ### Description of the Device Subject to Premarket Notification: The Tempus™ Cervical Plate System consists of screws and plates. Screws are available in a variety of diameter-length combinations. Plates are available in a variety of lengths to accommodate fusion procedures from one to five levels of the cervical spine. Fixation is achieved by inserting bone screws through the openings in the plate into the vertebral bodies of the cervical spine. The Tempus™ Plates include locking pins that cover the heads of the bone screws to reduce the potential for screw back-out. The locking pins come preassembled to the plate. #### Indications for Use The Tempus™ Cervical Plate System is intended for anterior cervical fixation (C2-T1) for the following indications: degenerative disc disease (DDD) (defined as neck pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies), spondylolisthesis, trauma (i.e., fracture or dislocation), spinal stenosis, deformities or curvatures (i.e., scoliosis, and/or lordosis), tumor, pseudoarthrosis, and failed previous fusion. The indication for use for the Tempus™ Cervical Plate System is similar to that of the Centerpulse Spine-Tech Trinica Select™ Anterior Cervical Plate System (K012305) and similar to that of Synthes Spine Anterior CSLP System (K030866). The Synthes device does not include deformity in the indications for use but is similar in all other aspects. As the subject device has indications that are identical to one of {1}------------------------------------------------ the predicate devices and similar to the second predicate device device does not introduce differences that are critical to the surgical use of the device. #### TECHNICAL CHARACTERISTICS The plates and screws are manufactured from titanium alloy meeting requirements of ASTM F136, Standard Specification for Wrought Titanium-6 Aluminum-4 Vanadium ELI (Extra Low Interstitial) Allov for Surgical Implant Applications (UNS R56401). Titanium alloy has a successful history of use in the spinal implant industry and use of it in these devices does not introduce any previously unaccepted patient risks. The Synthes CSLP plate is manufactured from commercially pure titanium, but the Trinica plate and Tempus™ plate are both manufactured from titanium alloy. The Tempus™ Plates include locking pins that cover the bone screws to reduce the potential for screw back-out. The locking pins come preassembled to the plate. Both of the predicate devices have an interference to the screw head with the same intent. The Synthes CSLP plate has an automatic locking mechanism that collapses over the head of the screw. The Trinica™ Plate has a manual locking cover that is engaged over the screw head after the place, similar in technical characteristics to the locking pin that is utilized in the Tempus™ plate. #### PERFORMANCE DATA The Tempus™ Cervical Plate System has been tested in static axial compression bending, static torsion, and dynamic axial compression bending in accordance with ASTM F1717–11 Standard Test Methods for Spinal Implant Constructs in a Vertebrectomy Model. The results of this non-clinical testing show that the Tempus™ Cervical Plate System can withstand the anticipated forces of the cervical spine and legally marketed predicate devices. #### CONCLUSION The overall technology characteristics and mechanical performance data lead to the conclusion that the Tempus™ Cervical Plate System is substantially equivalent to the predicate devices. {2}------------------------------------------------ #### DEPARTMENT OF HEALTH & HUMAN SERVICES Image /page/2/Picture/1 description: The image shows the logo for the U.S. Department of Health & Human Services. The logo consists of a stylized caduceus symbol, which features three diagonal lines that curve and merge into a single line at the bottom. The logo is surrounded by text that reads "DEPARTMENT OF HEALTH & HUMAN SERVICES USA" in a circular arrangement. #### Public Health Service Food and Drug Administration 10903 New Hampshire Avenue Document Control Room -WO66-G609 Silver Spring, MD 20993-0002 NeuroStructures, LLC % Meredith May, MS Empirical Testing Corp. 4628 Northpark Drive Colorado Springs, Colorado 80918 MAY 2 3 2012 Re: K120515 Trade/Device Name: Tempus Cervical Plate System Regulation Number: 21 CFR 888.3060 · Regulation Name: Spinal intervertebral body fixation orthosis Regulatory Class: Class II Product Code: K WQ Dated: February 16, 2012 Received: February 29, 2012 Dear Ms. May: We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate for too stated on the May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA).
