The provided text is a 510(k) Premarket Notification from the U.S. Food & Drug Administration (FDA) regarding several DePuy Synthes Craniomaxillofacial Neuro Devices. It describes changes to the labeling of these devices to indicate "MR Conditional" use.
The document consistently states that the purpose of the submission is to add MR Conditional information to the device labeling. It explicitly mentions that the intended use and technological characteristics of the devices remain unchanged. This implies that the devices are already cleared for their stated indications and the current submission is concerned with demonstrating their safety in an MR environment.
Therefore, the "acceptance criteria" and "study that proves the device meets the acceptance criteria" in this context refer to the non-clinical performance testing conducted to support the MR Conditional safety of the devices. This is not a study proving clinical effectiveness or diagnostic accuracy of an AI/algorithm-based device, but rather a set of engineering tests to confirm a physical device's compatibility with an MR environment.
Based on the provided text, here's how to address your request:
1. A table of acceptance criteria and the reported device performance:
The document repeatedly cites the ASTM standards as the basis for performance testing, which inherently contain acceptance criteria within them. The document does not provide specific quantitative performance results for each device against these criteria, but rather states that "Non-clinical testing is provided to support the conditional safety." This implies that the devices met the acceptance criteria defined by these ASTM standards.
| Acceptance Criteria (ASTM Standards) | Reported Device Performance |
|---|---|
| Magnetically Induced Displacement Force: ASTM F2052-14 | Non-clinical testing provided to support conditional safety. (Implied: Met standard) |
| Magnetically Induced Torque: ASTM F2213-06 | Non-clinical testing provided to support conditional safety. (Implied: Met standard) |
| Radio Frequency (RF) Heating: ASTM F2182-11a | Non-clinical testing provided to support conditional safety. The DUKE model places devices in the clinically relevant anatomic position. The DUKE results will be used for labeling of RF heating. (Implied: Met standard) |
| Image Artifacts: ASTM F2119-07 | Non-clinical testing provided to support conditional safety. (Implied: Met standard) |
2. Sample sized used for the test set and the data provenance:
- Sample Size: The document does not specify the number of individual devices or prototypes tested for each type of assessment (displacement, torque, heating, artifacts). These are engineering tests typically performed on representative samples.
- Data Provenance: The data provenance is "non-clinical testing" conducted by the manufacturer, DePuy Synthes. The "DUKE model" for RF heating is mentioned, which is a widely accepted phantom model for electromagnetic simulations in medical device testing. There's no information about the country of origin of the data beyond it being part of a US FDA submission. It is a prospective test in the sense that the testing was conducted to support the MR Conditional labeling.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
This question is not applicable in the context of this submission. The "ground truth" for MR Conditional safety is established by engineering tests against recognized consensus standards (ASTM), not by human expert review of clinical cases. The tests directly measure physical properties like temperature increase or magnetic force, and these measurements are compared to the limits specified in the standards.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:
Not applicable. This is not a human reader study requiring adjudication. The assessment is based on objective physical measurements and adherence to ASTM standards.
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 for physical medical devices (implants), not an AI/algorithm-based diagnostic or assistive software. No MRMC study was performed because the device is not an AI reading tool.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
Not applicable. This is not an algorithm, so standalone performance is irrelevant. The tests are for the physical properties of the implants.
7. The type of ground truth used (expert concensus, pathology, outcomes data, etc):
The "ground truth" for these tests is defined by the physical laws and empirically derived thresholds outlined in the ASTM standards for MR compatibility. For example, a certain temperature rise in a standard phantom model is deemed acceptable if it remains below a specified limit.
8. The sample size for the training set:
Not applicable. There is no "training set" as this is not a machine learning or AI model.
9. How the ground truth for the training set was established:
Not applicable, as there is no training set.
