The provided document, K192655, is a 510(k) Premarket Notification for DePuy Synthes Maxillofacial Portfolio - MR Conditional. This type of submission is a declaration from the manufacturer to the FDA that their device is substantially equivalent to a legally marketed predicate device, and it does not typically involve clinical performance studies with acceptance criteria as one would find for novel AI/ML medical devices.

Instead, the provided document focuses on demonstrating MR Conditional safety for a portfolio of existing maxillofacial bone plates and screw systems that were previously cleared by the FDA. The "acceptance criteria" and "study" described herein relate to non-clinical electromagnetic compatibility (EMC) testing in an MR environment, not clinical performance for diagnostic or therapeutic accuracy of an AI/ML algorithm.

Therefore, the requested information elements related to AI/ML device performance (e.g., sample size for test set, data provenance, number of experts for ground truth, adjudication methods, MRMC studies, standalone performance, training set details) are not applicable to this specific submission.

Here's a breakdown of the information that is available and relevant to the document's purpose:

Acceptance Criteria and Study for MR Conditional Safety (Non-Clinical)

The submission aims to add "MR Conditional" labeling to a portfolio of maxillofacial devices. This requires demonstrating that the devices are safe for use in a specified MR environment under defined conditions. The "acceptance criteria" for this type of submission are typically based on recognized international consensus standards for testing the MR compatibility of medical devices.

1. Table of Acceptance Criteria and Reported Device Performance

The document consistently references the following ASTM standards for non-clinical testing to support MR Conditional safety across all listed devices:

Note: The document states that "Non-clinical testing is provided to support the conditional safety..." for each of these parameters. While it doesn't provide specific quantitative results (e.g., exact temperature rise in °C, or N/A for displacement/torque if deemed safe), the acceptance of the 510(k) by the FDA implies that the results of these tests met the predefined safety thresholds for an MR Conditional designation as per the referenced ASTM standards. The specific numerical results (e.g., maximum temperature rises, displacement forces, etc.) would be detailed in the full test reports submitted to the FDA, which are not part of this public summary.

2. Sample Size Used for the Test Set and Data Provenance

• Sample Size: For non-clinical MR compatibility testing, the "sample size" refers to the number of device units tested. The document does not specify the exact number of physical devices or models tested for each parameter. However, standard practice for such assessments involves testing representative samples of each device type (plates, screws, meshes, distractors) and material compositions (titanium, titanium alloy) to ensure the portfolio's MR safety.
• Data Provenance: The data is "non-clinical testing" conducted by the manufacturer (Synthes - DePuy Synthes). The country of origin for the testing itself is not explicitly stated in this summary, but it would typically be conducted in a laboratory setting compliant with relevant international standards. This is retrospective in the sense that the studies were performed specifically to characterize the existing devices for MR compatibility.

3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications of those Experts

• Not Applicable. This is a non-clinical evaluation of physical device properties in an MR environment, not a clinical study involving expert interpretation of medical images or patient outcomes. The "ground truth" for MR safety is established by adherence to recognized ASTM testing standards and the physical properties of the materials and device in situ within the MR scanner, not by human expert consensus or annotations on medical data.

4. Adjudication Method for the Test Set

• Not Applicable. As this is non-clinical testing of physical device characteristics, there is no "adjudication" in the sense of resolving discrepancies between human readers or AI outputs. The test results are objective measurements against standard-defined thresholds.

5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

• Not Applicable. This submission is not for an AI-powered device.

6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done

• Not Applicable. This submission is not for an AI-powered device.

7. The Type of Ground Truth Used

• Physical Measurements against ASTM Standard Thresholds: The "ground truth" for MR Conditional safety is determined by rigorous physical measurements (e.g., temperature changes, displacement forces, torque, observable image artifacts) obtained through standardized testing protocols (ASTM F2052-14, F2213-06, F2182-11a, F2119-07) and comparison against acceptance limits defined by these standards or applicable regulatory guidance. It's about validating the device's behavior in an MR field, not diagnosing a condition. The "DUKE model" for RF heating indicates a high-fidelity computational human body model used for simulating temperature distributions due to RF fields.

8. The Sample Size for the Training Set

• Not Applicable. This is not an AI/ML device. There is no "training set" in the context of machine learning.

9. How the Ground Truth for the Training Set was Established

• Not Applicable. As there is no training set for AI/ML, this question doesn't apply.

The subject device is a fixation system consisting of plates and screws in a variety of shapes and sizes. All plates are made of commercially pure titanium conforming to ASTM F67, and all screws are made of Ti-6Al-4V alloy conforming to ASTM F136. The subject device includes the following groups: 1.5 System Plate, 2.0 System Plates, 2.4 System Plates, Orthognathic Plates, Blocking Screws (for intermaxillary fixation, 2.0 mm diameter), and screws for use with the various plates ranging in diameter from 1.5 mm to 2.7 mm.

It looks like the provided text is a 510(k) Summary for a CranioMaxillofacial Fixation (CMF) System, which is a medical device. This document focuses on demonstrating substantial equivalence to predicate devices rather than proving the device meets specific acceptance criteria through a clinical study.

Therefore, the input request asking for:

1. A table of acceptance criteria and reported device performance
2. Sample sizes for test set and data provenance
3. Number and qualifications of experts for ground truth
4. Adjudication method
5. MRMC comparative effectiveness study results
6. Standalone performance
7. Type of ground truth
8. Sample size for training set
9. How ground truth for training set was established

cannot be fully answered from the provided text. The document describes non-clinical data (mechanical testing, dimensional analysis, biocompatibility) to show equivalence, not clinical study results with acceptance criteria.

Here's what can be extracted and inferred from the text:

1. A table of acceptance criteria and the reported device performance

There isn't a table of "acceptance criteria" for clinical performance. The "performance data" reported in the document is non-clinical, demonstrating mechanical and material properties. The acceptance criterion for the 510(k) submission itself is "substantial equivalence" to predicate devices.

Non-clinical Performance Data Reported:

2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

This information is not provided as the submission relies on non-clinical engineering and laboratory testing, not a clinical test set.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

This information is not applicable/not provided as there was no clinical test set requiring expert ground truth for performance evaluation.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

This information is not applicable/not provided for the same reason as above.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

This information is not applicable/not provided. The device is not an AI-assisted diagnostic tool; it's a physical fixation system. No clinical comparative effectiveness study is mentioned, particularly an MRMC study.

6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done

This information is not applicable/not provided. The device is not an algorithm.

7. The type of ground truth used (expert concensus, pathology, outcomes data, etc)

For the non-clinical tests, the "ground truth" implicitly refers to established engineering standards (ASTM, ISO) for mechanical properties, material composition, and sterilization. For the comparison to predicate devices, the "ground truth" is the design and performance characteristics of the legally marketed predicate devices.

8. The sample size for the training set

This information is not applicable/not provided as the device is not an AI/ML algorithm requiring a training set.

9. How the ground truth for the training set was established

This information is not applicable/not provided for the same reason as above.

Summary of what the document focuses on instead:

The document describes a substantial equivalence claim for the CranioMaxillofacial Fixation (CMF) System - CMF Visionare. This means the manufacturer is asserting their device is as safe and effective as a legally marketed predicate device, and does not raise new questions of safety or effectiveness. This is primarily established through:

• Comparison of Indications for Use: The indications for use are reported as "identical" to the primary predicate device (K102641), with the only difference being the device names.
• Comparison of Technological Characteristics: Detailed tables (Tables 1-6) are provided comparing the subject device's plates (1.5 System, 2.0 System, 2.4 System, Orthognathic) and screws (Blocking, other screws) to those of the primary predicate device and several reference devices. These comparisons cover plate designs, dimensions (thickness, overall sizes, hole configurations), screw dimensions (diameter, threaded length), and material composition.
• Non-clinical Performance Data:
  • Sterilization validation: Conformed to ANSI/AAMI/ISO 17665-1 and ANSI/AAMI/ISO 14937.
  • Biocompatibility testing: Conformed to ISO 10993-5 and ISO 10993-12 (cytotoxicity testing).
  • Dimensional analysis: Engineering analysis of cross-sectional dimensions and bending moments of inertia "compared favorably" to predicate/reference devices.
  • Mechanical testing: Performed according to ASTM F382 (single cycle bending fatigue) and ASTM F543 (torsional properties, driving torque, axial pullout, self-tapping performance). The implication is that these tests demonstrate performance comparable to predicate devices.
• Material Equivalence: All subject device plates are CP titanium, and all screws are Ti-6Al-4V alloy, which are stated to be substantially equivalent to the materials of the primary predicate and most reference devices. A minor difference in screw alloy (Ti-6Al-7Nb) for some reference devices is identified but deemed not to affect intended use or raise new safety/effectiveness questions.

In essence, the study presented is a design and performance comparison against existing, cleared devices and recognized standards, rather than a clinical trial with specific performance acceptance criteria.
