AI/ML Overview

The provided text is related to a 510(k) premarket notification for the OsteoCoil™ Nitinol Compression System. It describes the device, its intended use, and a summary of non-clinical tests performed to demonstrate substantial equivalence to a predicate device. However, it does not contain any information about acceptance criteria or a study proving device performance against such criteria in the context of a clinical or standalone performance study involving AI or human readers.

Instead, the document details physical and material properties testing for a medical implant (bone fixation fastener).

Therefore, I cannot provide the requested information about acceptance criteria, device performance, sample sizes for test/training sets, data provenance, expert ground truth, adjudication methods, MRMC studies, or standalone algorithm performance, as these are not present in the provided text.

The closest information available is a list of non-clinical mechanical and material tests conducted to demonstrate substantial equivalence:

Non-Clinical Test Summary:

The following non-clinical tests were performed:

ASTM F543:
- Torsional Strength
- Driving and Removal Torque
- Axial Pullout Strength
- Self-tapping Force
ASRM F1264:
- Bending Fatigue
- Static 4Pt Bending
ASTM F2129: Pitting Corrosion Testing
ASTM F2004: Transformation Temperature Testing
Additionally:
- Extension and Compression Force Testing
- Bacterial endotoxin testing based on an endotoxin limit of 20EU/device per ANSI/AAMI ST72:2011
- Applicable testing per ISO 10993

Conclusion from the document: "The results demonstrate that the OsteoCoil™ Nitinol Compression System is substantially equivalent to the legalicate devices."

This document focuses on the mechanical and material safety/performance of a physical medical device, not a software or AI-driven diagnostic tool. Therefore, the concepts of acceptance criteria for diagnostic performance (e.g., sensitivity, specificity), ground truth establishment by experts, adjudication, or AI performance studies are not applicable here.

Regulation Number and Section

§ 888.3040 Smooth or threaded metallic bone fixation fastener.

(a)
Identification. A smooth or threaded metallic bone fixation fastener is a device intended to be implanted that consists of a stiff wire segment or rod made of alloys, such as cobalt-chromium-molybdenum and stainless steel, and that may be smooth on the outside, fully or partially threaded, straight or U-shaped; and may be either blunt pointed, sharp pointed, or have a formed, slotted head on the end. It may be used for fixation of bone fractures, for bone reconstructions, as a guide pin for insertion of other implants, or it may be implanted through the skin so that a pulling force (traction) may be applied to the skeletal system.(b)
Classification. Class II.
