The Curiteva Porous PEEK Laminoplasty System is intended for use in the lower cervical and upper thoracic spine (C3 to T3) in laminoplasty procedures. The Curiteva Porous PEEK Laminoplasty System is used to hold or buttress the allograft or autograft material in place in order to prevent the graft material from expulsion or impinging the spinal cord.

The Curiteva Porous PEEK Laminoplasty System is an internal fixation device for spinal surgery that consists of various configurations of plates and screws. The implant configurations are available in different types and sizes so that adaptations can be made to take into account pathology and individual patient anatomy. The plates come preformed with holes to receive bone screws. Screws are used to attach the plates to bone. System plate configurations may be used with allograft or autograft material. A hinge plate is provided when additional stabilization is necessary.

All system components are manufactured from Titanium alloy (Ti-6A1-4V ELI) that conforms to ASTM F136, or PEEK (Polyetheretherketone) as described by ASTM F2026.

The Curiteva Porous PEEK Laminoplasty implants are sterile, single-use devices and available in a variety of different sizes to accommodate the individual pathology and anatomical conditions of the patient. The implants have solid and porous PEEK regions.

The Curiteva Porous PEEK Laminoplasty implants are manufactured from implant-grade PEEK (per ASTM F2026). Each porous PEEK implant has been surface treated with a hydroxyapatite (HA) coating that is approximately 20nm thick.

The provided text is a 510(k) Premarket Notification from the FDA regarding the Curiteva Porous PEEK Laminoplasty System. This document is a clearance letter for a medical device and does not contain information about an AI/ML (Artificial Intelligence/Machine Learning) device or its performance study.

Therefore, I cannot provide the requested information regarding acceptance criteria and the study that proves an AI/ML device meets those criteria, as the input document is not about such a device. The key information points requested (test set sample size, data provenance, expert panels, adjudication, MRMC studies, standalone performance, ground truth establishment, training set details) are specific to the validation of AI/ML models, which is not discussed in this medical device clearance document.
