The Raven Lumbar Plate System Anterior and Lateral Plates are indicated for use via a lateral or anterolateral surgical approach above the bifurcation of the great vessels in the thoracic and thoracolumbar (TI-LS) spine or via an anterior approach below the bifurcation of the great vessels in the treatment of lumbar and lumbosacral (L1-S1) spine. The system is intended to provide additional support during fusion in skeletally mature patients in the treatment of the following acute and chronic instabilities or deformities:

· Degenerative Disc Disease (defined as back pain of discogenic origin with degeneration of the disc confirmed by patient history and radiographic studies);

· Pseudoarthrosis;
· Spondylolysis;
· Spondylolisthesis:
· Spinal stenosis;
Tumors;
· Trauma (i.e. Fractures or Dislocation);
· Deformities (i.e. Scoliosis, Kyphosis or Lordosis);
Failed Previous Fusion

The Raven Lumbar Plate System Buttress Plate is intended to stabilize the allograft at one level (T1-S1) as an aid to spinal fusion and to provide temporary stabilization and augment of a solid spinal fusion. It may be used alone or with other anterior, anterolateral, or posterior spinal systems made of compatible materials. This device is not intended for load bearing applications.

Device Description

Raven Lumbar Plate System is an anterior/anterolateral/lateral plate system that may be used in the thoracic, lumbar, and sacral spine (T1-S1). Raven Lumbar Plate System consists of plates and screws manufactured from titanium alloy (Ti-6Al-4V ELI) per ASTM F136, as well as associated manual general surgical instrumentation. The implants are available in a variety of sizes to accommodate various patient anatomies.

AI/ML Overview

The provided text is a 510(k) summary for the Raven Lumbar Plate System, a spinal intervertebral body fixation orthosis. It primarily describes the device, its indications for use, and its substantial equivalence to predicate devices through a risk analysis and mechanical testing.

Crucially, this document does not contain information about the performance of a software algorithm or AI device. The acceptance criteria mentioned refer to mechanical testing of the physical implant (Static and dynamic compression testing per ASTM F1717-15, and Static torsion testing per ASTM F1717-15), not the performance of a device that uses data, ground truth, or human experts as described in your request.

Therefore, I cannot extract the information required in your prompt based on the provided text. The prompt asks for details pertaining to the rigorous evaluation of a software or AI device, including aspects like sample size for test and training sets, expert adjudication, MRMC studies, and ground truth establishment. None of these concepts are addressed in the provided FDA 510(k) letter for a physical orthopedic implant.

If you have a document describing the evaluation of a medical device that is a software or AI product, please provide that text, and I will do my best to answer your questions.

Dear Kim Finch:

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 requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for

{1}------------------------------------------------

devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/CombinationProducts/GuidanceRegulatoryInformation/ucm597488.html; good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to http://www.fda.gov/MedicalDevices/Safety/ReportaProblem/default.htm.

For comprehensive regulatory information about medical devices and radiation-emitting products, including information about labeling regulations, please see Device Advice (https://www.fda.gov/MedicalDevices/DeviceRegulationandGuidance/) and CDRH Learn (http://www.fda.gov/Training/CDRHLearn). Additionally, you may contact the Division of Industry and Consumer Education (DICE) to ask a question about a specific regulatory topic.

Regulation Number and Section

§ 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.
