AI/ML Overview

The provided document is a 510(k) summary for the Lumenis M22 and ResurFX Systems, which are laser surgical instruments. It focuses on demonstrating substantial equivalence to predicate devices rather than proving a device meets specific clinical performance acceptance criteria through studies involving human-in-the-loop or standalone algorithm performance.

Therefore, many of the requested details about acceptance criteria, study types, sample sizes, expert involvement, and ground truth establishment are not present in this type of regulatory document. This document details engineering and performance bench testing to ensure the modified device functions as intended and safely, similar to its predicate.

Here's an analysis of the information that can be extracted from the document:

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

The document doesn't present a table of specific clinical acceptance criteria with corresponding performance metrics like sensitivity, specificity, or accuracy for a diagnostic or AI-driven device. Instead, the "acceptance criteria" are implied by the performance bench testing ensuring the device meets safety and operational standards and functions as intended, similar to the predicate devices. The "reported device performance" is essentially that it passed these engineering and safety tests.

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

Not applicable. This is a 510(k) for a device modification, focusing on engineering verification and validation (V&V) and safety testing. There is no "test set" in the context of clinical data for an AI algorithm. The V&V activities involve testing the physical device and its components.

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)

Not applicable. No "ground truth" was established by clinical experts for a test set, as this is not a study of an AI or diagnostic device's clinical performance.

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

Not applicable. No clinical test set requiring adjudication was used.

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 document is not about an AI-assisted diagnostic device, but rather a laser surgical instrument. Therefore, no MRMC study was conducted or reported.

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

Not applicable. This device does not have a standalone algorithm in the sense of a diagnostic or image interpretation AI. Its "standalone" characteristic refers to the ResurFX system being made available as a separate unit rather than just a module of the M22. This is a hardware device for treatment, not an algorithm for analysis.

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

Not applicable. The ground truth for this device's performance is its physical and electrical specifications, and its ability to function safely and effectively within those parameters as demonstrated by engineering bench testing and compliance with recognized standards.

8. The sample size for the training set

Not applicable. This is not an AI/ML device that requires a training set.

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

Not applicable.
