The summary describes a physical implantable device (shoulder prosthesis) and its intended use, materials, and mechanical testing. There is no mention of software, algorithms, data analysis, or any other components typically associated with AI/ML. The performance studies focus on mechanical properties and MRI compatibility.
Yes.
The device is intended for long-term implantation into the human shoulder joint to relieve pain and restore function, specifically addressing conditions like arthritis, avascular necrosis, and fractures, which aligns with the definition of a therapeutic device.
No
This device is an artificial shoulder joint system intended for implantation to relieve pain and restore function, not to diagnose a condition.
No
The device description clearly describes physical implants (shoulder prosthesis components) and their intended use in surgical procedures. There is no mention of software as the primary or sole component of the device.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, or tissue) to provide information for diagnosis, monitoring, or screening.
- Device Description and Intended Use: The text clearly describes the device as a shoulder prosthesis intended for long-term implantation into the human shoulder joint to relieve pain and restore function. It is a physical implant used in surgical procedures.
- Lack of Specimen Analysis: There is no mention of the device being used to analyze any biological specimens. Its function is purely mechanical and structural within the body.
Therefore, this device falls under the category of a surgical implant rather than an In Vitro Diagnostic device.

Device Description
The ASHCOM Shoulder AC-Connector is a double tapered Adaptor that allows the combination of the Anatomical Shoulder Humeral Stems with the Comprehensive Trays. The male oval cone taper of the ASHCOM Shoulder AC-Connector is compatible with the cemented, uncemented and fracture humeral stems of the Anatomical Shoulder System. The female round taper is compatible with the Comprehensive Reverse Trays. In combination with compatible Zimmer Biomet reverse glenoid the implant is intended for a reverse application. The existing Anatomical Shoulder System, for which MR conditional labeling is proposed, is a modular shoulder prosthesis designed to be used in primary or revision, total or hemi shoulder arthroplasty. The existing Anatomical Shoulder Combined System, for which MR conditional labeling is proposed, allows the combination of a Bigliani/Flatow® Head with any Anatomical Shoulder Humeral Stem.

Comparison to Predicate Device:
The ASHCOM AC-Connector allows the combination of the Anatomical Shoulder Humeral Stems with the Comprehensive Reverse Trays. The indications are shared with the reverse application of the Anatomical Shoulder predicate device. The ASHCOM AC-Connector utilizes the same material as the Anatomical Shoulder Humeral Stem and the same manufacturing process, and has similar technical features as the Anatomical Shoulder predicate device.
This submission further covers a labeling modification to the existing Anatomical Shoulder and Anatomical Shoulder Combined System. The labeling modification consists of the addition of Magnetic Resonance Imaging (MRI) compatibility information to the Package Insert, and application of the "MR
9
Conditional" symbol on the package label. No other changes are proposed.
Performance Data (Nonclinical and/or Clinical):
Results of non-clinical performance testing and analyses demonstrate that the ASHCOM Shoulder System is safe and effective and substantially equivalent to the predicate devices. Performance analyses included:
- Finite Element Stress analysis and cyclic fatigue testing under worst case conditions 2. Accelerated Corrosion Fatigue Testing 3. Static taper connection testing according ASTM F2009
The components of the ASHCOM Shoulder System, the Anatomical Shoulder System and the Anatomical Shoulder Combined System and have been evaluated for compatibility in the MRI environment, per Guidance for Industry and FDA Staff, "Establishing Safety and Compatibility of Passive Implants in the Magnetic Resonance (MR) Environment", August 2014. Based upon the results, the subject shoulder implants are recommended to bear the "MR Conditional" labeling and include MR compatibility safety information within the package insert.
Clinical Performance and Conclusions: Clinical data and conclusions were not needed to demonstrate substantial equivalence.
