The Nd: YAG Laser System is based on the Q-Switched Nd:YAG (1064 nm) and frequency doubled KTP Nd:YAG (532 nm) laser technology. There is one optical cavity containing the Nd:YAG crystal. The frequency doubled KTP Nd:YAG wavelength is achieved by directing the Nd:YAG laser beam through a frequency doubling non-linear crystal. The Nd:YAG laser is activated by means of the use of flashlamp. A red diode aiming beam is reflected onto a coaxial beam path using a beamsplitter assembly. The combined therapeutic and aiming beams are guided by articulated arm to a focusing handpiece.

Both laser wavelengths share a common power supply, control system, and cooling system. The internal microprocessor can be directed to select either the Nd:YAG or the KTP Nd:YAG laser wavelength. The physician is able to select the desired wavelength and the related output energy ,spot size ,fluence via control panel.

The provided text describes a 510(k) premarket notification for the Nd: YAG Laser System (Qmetrx 1000 (Victory 11)) and assesses its substantial equivalence to predicate devices. However, it does not include information about specific acceptance criteria related to device performance in a clinical context (e.g., efficacy rates for tattoo removal, lesion clearance), nor does it detail a study proving the device meets such criteria through clinical endpoints.

Instead, the document focuses on non-clinical testing to ensure safety and compliance with recognized standards.

Here's an analysis of the provided information, addressing your questions based on what is available:

1. Table of Acceptance Criteria and Reported Device Performance

Based on the provided text, there are no specific performance acceptance criteria (e.g., target percentages for lesion clearance or tattoo fading) or a report of the device's clinical performance against such criteria. The "Testing" section focuses on compliance with international safety and electrical standards.

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

The document explicitly states: "No Clinical Information is required." Therefore, there was no clinical test set in the traditional sense of patient data. The testing mentioned refers to laboratory testing for safety and design specifications. There is no information about data provenance (country of origin, retrospective/prospective) for a clinical test set because none was used.

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

As no clinical test set was used, no experts were utilized to establish ground truth for a clinical test set. The grounding of the device's safety and effectiveness relies on compliance with engineering standards and comparison to previously approved predicate devices by the FDA.

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

Not applicable, as no clinical test set 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 device is a laser system, not an AI-based diagnostic or assistive tool for human readers. No MRMC study was performed.

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

Not applicable. This is a physical medical device (laser system), not a software algorithm.

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

For the non-clinical testing, the "ground truth" was established by adherence to the specified international and national safety and performance standards (e.g., IEC 60825-1, IEC 60601 series, UL 60601-1). The device's "effectiveness" from the perspective of this 510(k) is primarily established through its substantial equivalence to the predicate devices, which means it shares similar indications for use, design, and functional features, implying similar efficacy outcomes based on the predicate's established history.

8. The sample size for the training set

Not applicable. There is no mention of a training set as this is not an AI/machine learning device.

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

Not applicable. There is no mention of a training set.
