AI/ML Overview

The provided text is a 510(k) summary for the Stellar M22 for Intense Pulsed Light (IPL) and Laser system. This document outlines the device's intended use, technological characteristics, and compares it to a predicate device (M22 System, K170060) to establish substantial equivalence.

However, the summary does not include specific acceptance criteria or details of a study that proves the device meets those criteria in a quantitative sense as often seen in clinical performance studies with specific endpoints. Instead, it describes "Performance Data" in the context of design verification, compliance with standards, and software validation to demonstrate that modifications to the device do not raise new questions of safety or effectiveness compared to the predicate device.

Therefore, many of the requested items (e.g., sample size for test set, number of experts for ground truth, MRMC study, standalone performance) are not detailed in this type of regulatory submission, as it focuses on demonstrating substantial equivalence rather than proving a specific diagnostic accuracy or treatment efficacy de novo.

Below is a summary based on the information provided, with "N/A" for information not present in the document.

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

The document does not explicitly present acceptance criteria in a quantitative table format that measures specific performance metrics against a defined threshold. Instead, it focuses on demonstrating that the Stellar M22 device's modifications do not introduce new safety or effectiveness concerns compared to its predicate. The "reported device performance" is framed in terms of functional verification and compliance with standards.

Acceptance Criteria CategoryReported Device Performance/Compliance
Design Verification & ValidationTests performed to validate modifications to the device (specifics not detailed)
Risk AnalysisCompliance with ISO 14971
Electrical SafetyCompliance with IEC 60601-1
Electromagnetic Compatibility (EMC)Compliance with IEC 60601-1-2
IPL CompatibilityCompliance with IEC 60601-2-57
Software Verification & ValidationTests performed (specifics not detailed)
Technological Characteristics EquivalenceThe device's technological characteristics (wavelength, pulse duration, maximum fluence, etc.) are substantially equivalent to the predicate, with minor modifications not raising new safety/effectiveness questions (see detailed comparison table in the source text).

2. Sample size used for the test set and the data provenance

N/A - The document describes general performance data related to engineering verification and validation, and compliance with standards. It does not refer to a clinical "test set" with a specific sample size of patients or images for diagnostic or therapeutic performance evaluation. The data provenance is also not specified in terms of country of origin or retrospective/prospective nature, as this is not a clinical study report.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

N/A - No clinical "test set" requiring ground truth established by experts is described in this regulatory submission for substantial equivalence.

4. Adjudication method for the test set

N/A - No clinical "test set" or adjudication method is described.

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

N/A - This document does not describe an MRMC comparative effectiveness study or involve AI assistance for human readers. The device is a laser and IPL system for dermatological procedures, not an AI-powered diagnostic tool.

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

N/A - This device is a medical instrument (laser and IPL system), not an algorithm or AI system. Therefore, standalone algorithm performance is not applicable.

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

N/A - As there is no clinical "test set" for performance evaluation in the context of diagnostic accuracy or treatment efficacy against a reference standard, the concept of ground truth in that sense is not detailed. The performance data focuses on engineering and safety compliance.

8. The sample size for the training set

N/A - The document does not describe a "training set" in the context of machine learning or AI algorithms.

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

N/A - Not applicable, as there is no mention of an AI training set or related ground truth.
