The provided text describes a 510(k) premarket notification for the Viora V-VR Handpiece compatible with V30, V20, V10 Systems. The document focuses on demonstrating substantial equivalence to predicate devices rather than providing a detailed study proving the device meets specific performance acceptance criteria for a new clinical claim.

Therefore, much of the requested information regarding acceptance criteria, study methodologies, sample sizes, expert involvement, and ground truth establishment, which are typical for studies validating a new clinical claim or an AI/ML device, are not present in this regulatory submission. This submission is for a modified accessory (handpiece) with similar intended use to an already cleared device, primarily relying on bench testing and software validation to show equivalence and safety, not on a new clinical study.

However, based on the information provided, here's what can be extracted:

1. Table of Acceptance Criteria and Reported Device Performance:

The document outlines performance standards for safety and electrical characteristics rather than clinical efficacy metrics. The primary "acceptance criterion" demonstrated through bench testing is the capability of the V-VR Handpiece to safely maintain superficial skin therapeutic temperature between 40-45 ℃ during 14 minutes of treatment.

2. Sample size used for the test set and the data provenance:
The document does not mention a clinical test set or patient data. The validation relies on bench testing for performance, electrical safety, EMC, and software. There is no mention of country of origin or whether data was retrospective or prospective, as it's not a data-driven clinical study.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
Not applicable as no clinical test set requiring expert ground truth for a diagnostic or AI claim was conducted. The "ground truth" for the engineering and safety tests is based on established industry standards (IEC, ISO) and internal device specifications.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:
Not applicable as no clinical test set requiring adjudication was conducted.

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 is not an AI/ML device for diagnostic or interpretive purposes, nor a device that assists human readers.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
Not applicable. This is a medical device (handpiece) that performs a physical therapeutic action, not an algorithm.

7. The type of ground truth used (expert concensus, pathology, outcomes data, etc):
The "ground truth" for this regulatory submission is adherence to safety and performance standards (IEC, ISO), as measured by technical bench tests and software validation. For the clinical claims (temporary relief of minor muscle aches and pain, etc.), the device relies on substantial equivalence to the predicate devices which had already established these indications.

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.

Summary of the Study:

The "study" described in this 510(k) summary is primarily a series of non-clinical bench tests and engineering analyses to demonstrate that the new V-VR Handpiece, when used with existing Viora systems (V10, V20, V30), is as safe and effective as the predicate V-ST Handpiece, and meets applicable safety standards. The core argument for acceptance is substantial equivalence to already cleared devices, rather than a de novo clinical demonstration of efficacy.

The key tests performed were:

• V-VR IR temperature assessment: To verify its capability to safely maintain superficial skin therapeutic temperature (40-45 ℃ for 14 minutes).
• Electrical Safety & EMC Testing: Conformance to IEC standards (60601-1, 60601-1-2, 60601-2-57, 60601-2-22, 60825-1).
• Biocompatibility Testing: Conformance to ISO 10993-1.
• Software Verification and Validation: To ensure the software supporting the handpiece functions correctly and as intended.

The acceptance criteria are therefore implicit in meeting these standards and demonstrating performance per device specifications, without needing a separate clinical study with patient samples or expert adjudication for this specific submission.

The FDA 510(k) clearance letter and summary for the Viora V30, V20, V10 Systems and V-FR Handpiece (K201064) provides information about the device's substantial equivalence to predicate devices, but it does not include acceptance criteria or the specifics of a study proving the device meets those criteria in the typical sense of a clinical performance study with predefined endpoints and statistical analysis.

Instead, the document focuses on demonstrating substantial equivalence through:

• Comparison of technological characteristics with predicate devices.
• Non-clinical testing, including electrical safety, electromagnetic compatibility, performance bench tests, biocompatibility, and software verification/validation.
• An animal study to evaluate safety and effectiveness for the indicated use.

Therefore, many of the requested categories for a study proving acceptance criteria cannot be directly extracted from this document in the traditional format. However, I can provide the available information:

1. Table of "Acceptance Criteria" (interpreted as performance standards and study findings) and Reported Device Performance:

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

• Test Set (Animal Study): "female domestic pigs (Sus scrofa domestica)" were used, but the specific number (sample size) is not provided.
• Data Provenance: The animal study was "prospective" as described, but the country of origin of the data is not explicitly stated.

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

• The document mentions "Histopathological evaluation of the tissue samples" but does not specify the number or qualifications of experts performing this evaluation in the animal study.

4. Adjudication Method for the Test Set:

• The document does not describe an adjudication method for the animal study.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study:

• No MRMC comparative effectiveness study involving human readers and AI assistance was mentioned or conducted, as this device (V-FR Handpiece) is a fractional radiofrequency device, not an AI-assisted diagnostic tool.

6. Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study:

• This is not applicable as the device is a physical medical device (RF handpiece) and not an AI algorithm. Its performance is evaluated through bench testing and animal studies.

7. Type of Ground Truth Used (Animal Study):

• Histopathology/Histopathological evaluation: This involved examining skin biopsies for depth/width of ablated tissue, coagulative necrosis, and signs of healing/complications.
• Macroscopic evaluation: Local reactions were evaluated grossly.

8. Sample Size for the Training Set:

• Not applicable/Not provided: This device does not involve an AI algorithm with a distinct "training set" in the context of machine learning. The "training" for the device, if one considers it, would be its design, engineering, and manufacturing based on existing medical device knowledge and standards.

9. How the Ground Truth for the Training Set Was Established:

• Not applicable: As noted above, there is no AI training set in the context of this device. Ground truth for the device's design and functionality would stem from established medical physics, dermatology principles, and engineering standards.
