No
The description focuses on the mechanical components and intended use of a cervical plate system, with no mention of AI or ML capabilities.
Yes
The device aids in the stabilization of the anterior cervical spine to promote fusion, which is a treatment for various medical conditions like spinal stenosis, degenerative disc disease, and tumors. This function directly contributes to restoring or improving a patient's health, thus qualifying it as a therapeutic device.
No
The KASILOF Cervical Plate System is a surgical implant designed to provide mechanical support and stabilization for spinal fusion, not to diagnose medical conditions.
No
The device description explicitly states it is a "plate and screw system composed of medical grade titanium Ti-Alloy" and includes details about physical components like plates, screws, and instruments for implantation. This indicates it is a hardware-based medical device, not software-only.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body (like blood, urine, tissue) to provide information about a person's health. These tests are performed outside of the body.
- KASILOF Cervical Plate System: This device is an implantable surgical device used to stabilize the cervical spine within the body. It is a mechanical support system, not a diagnostic test.
The description clearly states its purpose is for "anterior screw fixation to the cervical spine" and "to provide mechanical support to the implanted level(s) until fusion is achieved." This is a therapeutic device, not a diagnostic one.

Intended Use / Indications for Use
The KASILOF Cervical Plate System is intended for anterior screw fixation to the cervical spine. It is to be used in skeletally mature patients as an adjunct to fusion from levels C2 through T1 of the system is indicated for use in the stabilization of the anterior cervical spine during the development of cervical spinal fusion in patients. The indications include spinal stenosis, degenerative disc disease (as defined by neck pain of discogenic origin with degeneration of the disc confirmed by patient history and radiographic studies,), tumors, deformity (defined by kyphosis, lordosis, or scoliosis), and/or pseudarthrosis (defined as failed previous fusion).

Device Description
The KASILOF Cervical Plate System is a plate and screw system composed of medical grade titanium Ti-Alloy (Ti-6A-I4V ELI) components. The titanium plates are available in a variety of lengths, addressing multiple levels of fixation. The plates contain an integrated locking mechanism which interfaces with fixed and variable angled screws, of various diameters and lengths, to accommodate anatomical variation when securing the plate-screw construct to the anterior cervical vertebral bodies. The system is intended to provide mechanical support to the implanted level(s) until fusion is achieved. To accommodate normal cervical spine lordosis, and at the same time eliminate the need for additional plate contouring, KASILOF Cervical Plates come with a pre-lordosed curve. Various instruments are available to facilitate the implantation of the device.

§ 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.

Dear Ms. Dunahoo:
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 commerce prior to 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). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's
