The Biocore9 Humeral Head Resurfacing Shoulder Component is intended for the reconstruction of painful and/or severely disabled shoulder joints resulting from osteoarthritis. For proper function of this device, the humeral head and neck must be of sufficient bone stock to support the loads on it. Also, the presence of an intact or reconstructable rotator cuff is important for proper functioning and dislocation resistance. Porous-coated components are intended for cemented use only. This device is indicated for hemi-arthroplasty only.

The Biocore9 Humeral Head Resurfacing Shoulder Component is intended for the reconstruction of painful and/or severely disabled shoulder ioints resulting from osteoarthritis and rheumatoid arthritis. For proper function of this device, the humeral head and neck must be of sufficient bone stock to support the loads on it. Also, the presence of an intact or reconstructable rotator cuff is important for proper functioning and dislocation resistance. Porous-coated components are intended for cemented use only. This device is indicated for hemi-arthroplasty only.

The Biocore9 Humeral Head Resurfacing component is a non-constrained orthopedic implant intended to replace the articular surface of the existing humeral head in the patient's shoulder joint. It is intended for the reconstruction of painful and or severely disabled shoulder joints resulting from osteoarthritis or rheumatoid arthritis for patients who would be candidates for total shoulder procedure, whose proximal humerus has not been excessively damaged by disease or trauma and where damage is primarily associated with the articular surface of the humeral head. It is primarily intended to articulate with intact, natural, glenoid. Components are available in five sizes with available outside diameters from 40 mm to 56 mm in 4 mm increments.

The Biocore9 Humeral Resurfacing Head Component is manufactured from Ti-6Al-4V alloy (ASTM F136-13) with a Titanium Nitride (TiN) thin film ceramic coating. The Humeral Resurfacing component is axisymmetric with a truncated shell and a tapered central stem. The component consists of a thin walled spherical shell. The Humeral resurfacing Component's rim is anatomical with a rounded relief. The exterior of the spherical surface is intended to articulate with the Glenoid.

The internal surface of the spherical shell is covered with a porous coating consisting of titanium beads. The stem is not porous coated.

This document describes the Biocore9 Humeral Resurfacing System, a medical device. However, it does not contain information about studies proving the device meets acceptance criteria related to a machine learning or AI model's performance. The sections detailing "Non-Clinical Performance Testing" relate to the physical properties and performance of the implant itself (e.g., tensile strength, wear resistance), not the evaluation of an AI model's output.

Therefore, I cannot provide the requested information about acceptance criteria and study details for an AI/ML device per your prompt. The provided text describes a traditional medical device (a prosthetic humeral head) and its materials, design, intended use, and non-clinical engineering performance testing for substantial equivalence to a predicate device.
