Intended 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, kyphosis, and/or lordosis), tumor, pseudoarthrosis, and failed previous fusion.
Device Description
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.
More Information

No
The device description and performance studies focus on the mechanical properties and fixation capabilities of a cervical plate system, with no mention of AI or ML.

Yes
The device is a medical implant intended to fix the cervical spine for various conditions, directly treating and alleviating medical conditions.

No

The device description clearly states that the Tempus™ Cervical Plate System is used for fixation by inserting screws into vertebral bodies, which is a treatment modality, not a diagnostic one. Its stated intended use is to treat various conditions like degenerative disc disease or trauma, not to diagnose them.

No

The device description explicitly states that the system consists of screws and plates, which are hardware components.

Based on the provided information, the Tempus™ Cervical Plate System is not an IVD (In Vitro Diagnostic) device.

Here's why:

  • Intended Use: The intended use clearly describes a surgical implant for fixing the cervical spine. This is a therapeutic device used in vivo (within the body) during surgery.
  • Device Description: The description details screws and plates, which are physical implants.
  • Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, tissue, etc.) to provide information for diagnosis, monitoring, or compatibility testing.

IVD devices are used in vitro (outside the body) to analyze biological samples. The Tempus™ Cervical Plate System is a surgical implant used in vivo.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

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.

§ 888.3060 Spinal intervertebral body fixation orthosis.

(a)
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.(b)
Classification. Class II.

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.
