I apologize, but I cannot fulfill your request to create a table of acceptance criteria and reported device performance, nor can I describe a study that proves the device meets specific acceptance criteria based solely on the provided FDA 510(k) Clearance Letter for TRUDERMAL Pro (ZLD-390).

Here's why:

• No Performance Data or Acceptance Criteria in the Document: The provided 510(k) clearance letter and its associated summary (510(k) Summary) do not contain any information about specific performance acceptance criteria or the results of clinical performance studies that demonstrate the device meets such criteria.
  • The document states, "Clinical testing was not needed for this 510(k). The non-clinical performance testing described above is sufficient to support that the device can be used safely and effectively." This explicitly indicates that no clinical performance data (which would typically include performance against acceptance criteria) was provided or evaluated for this 510(k) submission.
  • The non-clinical tests mentioned (electrical safety, EMC, biocompatibility, software V&V) are regulatory compliance tests, not performance studies assessing the therapeutic efficacy against specific clinical endpoints or acceptance criteria.

Therefore, I cannot extract or infer the following information from the provided text:

1. Table of acceptance criteria and reported device performance: This data is not present. The document explicitly states clinical testing was not needed.
2. Sample size used for the test set and data provenance: Since no clinical performance study was conducted or reported, there is no test set, sample size, or data provenance information.
3. Number of experts used to establish ground truth & qualifications: Not applicable, as no clinical performance study data relying on expert ground truth is provided.
4. Adjudication method for the test set: Not applicable.
5. MRMC comparative effectiveness study: Not conducted or reported. The device is a phototherapy device, not an AI-powered diagnostic tool, so an MRMC study is generally not relevant.
6. Standalone (algorithm only) performance study: Not applicable. This is a physical phototherapy device, not an algorithm.
7. Type of ground truth used: Not applicable.
8. Sample size for the training set: Not applicable, as this is a phototherapy device, not an AI model that would have a "training set" in the traditional sense.
9. How ground truth for the training set was established: Not applicable.

What the document does provide regarding "performance" is:

• Comparison to Predicate Devices: The submission argues for substantial equivalence by comparing the TRUDERMAL Pro's technical characteristics (wavelengths, irradiance, treatment time) to legally marketed predicate devices. The claim is that "The subject device's wavelengths, treatment time, irradiance and radiation dose are similar and close to those of the predicate devices," and this, combined with non-clinical tests, "supports that the subject device is safe and as effective as the predicate devices for its intended use."
• Non-Clinical Test Summary: This section lists the electrical safety, electromagnetic compatibility, biocompatibility, and software verification/validation tests performed, demonstrating compliance with relevant industry standards (IEC, ISO). These tests ensure the device is safe and functions as designed electrically and mechanically, but they do not prove clinical efficacy against specific performance metrics related to wrinkle reduction, acne treatment, or pain relief.

In summary, the provided FDA document is a clearance letter and 510(k) summary that emphasizes substantial equivalence to existing predicate devices based on design, intended use, and non-clinical safety testing, rather than presenting a performance study with defined acceptance criteria and clinical results.

This device is an LED light therapy mask intended for treatment of full-face wrinkles, falling under the regulation 21 CFR 878.4810 (Laser Surgical Instrument For Use In General And Plastic Surgery And In Dermatology). The primary focus of the regulatory review for such a device is safety and effectiveness based on its physical properties and intended use for cosmetic purposes, rather than diagnostic accuracy or AI-driven image analysis.

Therefore, many of the requested elements are not applicable to the information provided in this document. The document explicitly states:

• "Clinical testing is not needed for this 510(k)."
• "The non-clinical performance testing described above is sufficient to demonstrate that the device can be used safely and effectively."

This indicates that the device's clearance was based on demonstrating substantial equivalence to a predicate device through non-clinical tests (electrical safety, EMC, photobiological safety, battery safety, biocompatibility, and software verification/validation) and not on clinical performance metrics like sensitivity, specificity, or reader studies for diagnostic accuracy.

Addressing the Request Based on the Provided Document:

Given the nature of the device and the clearance documentation, I will answer the applicable points and explain why others are not present.

Acceptance Criteria and Device Performance for CurrentBody Skin™ LED Light Therapy Mask Series 2 (K250966)

The CurrentBody Skin™ LED Light Therapy Mask Series 2 is an LED phototherapy device for the treatment of full-face wrinkles. The acceptance criteria and performance evaluation for this device, as detailed in the 510(k) summary, are primarily focused on safety, electrical performance, material compatibility, and functional equivalence to a predicate device, rather than diagnostic performance metrics (e.g., accuracy in identifying wrinkles).

1. Table of Acceptance Criteria and Reported Device Performance

The concept of "acceptance criteria" for this device is primarily based on compliance with specific international safety and performance standards, and demonstrating substantial equivalence to a predicate device for its intended use. "Device performance" is therefore reported in terms of compliance with these standards and matching key operational parameters with the predicate.

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

Not applicable for performance evaluation in the context of typical AI/ML diagnostic devices. The clearance is based on non-clinical engineering and safety testing, component material equivalence, and functional equivalence to a predicate device. There is no "test set" of patient data or images in the conventional sense for evaluating diagnostic accuracy or clinical outcomes directly in this 510(k) submission.

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

Not applicable. No ground truth established by experts for a test set of clinical data, as no clinical performance study was conducted or required for this 510(k). Approval is based on safety, hardware specifications, and substantial equivalence.

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 is not a diagnostic AI device. No MRMC study was conducted or is relevant for this product's intended use (treatment of wrinkles).

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

Not applicable. This device is a hardware LED light therapy mask. While it has software for control (e.g., timer), it is not a standalone diagnostic algorithm.

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

The "ground truth" for this device's clearance is not related to clinical data or diagnostic accuracy. Instead, the "truth" is established by:

• Compliance with recognized international standards for electrical safety, electromagnetic compatibility, photobiological safety, battery safety, and biocompatibility.
• Demonstration of substantial equivalence (same intended use, similar technological characteristics, and no new questions of safety or effectiveness) to a legally marketed predicate device (K221946).

For the purpose of treatment effectiveness validation in general, the underlying scientific basis for LED light therapy's effect on wrinkles (which is outside the scope of this specific 510k submission's clearance process details) would typically stem from clinical trials and dermatological research. However, this 510(k) relies on the predicate's established performance without new clinical studies.

8. The sample size for the training set

Not applicable. This device is not an AI/ML algorithm that requires a training set of data for learning or inference.

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

Not applicable. As above, no training set for an AI/ML algorithm.

In summary, the provided 510(k) clearance letter details an approval based on substantial equivalence and compliance with safety and performance standards for a hardware medical device, not on the clinical performance or diagnostic accuracy of an AI/ML driven system. Therefore, many of the requested details regarding AI/ML study methodologies are not present in this document.

2. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable.
3. Adjudication method for the test set: Not applicable.
4. 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 generally for diagnostic AI devices, not a therapeutic device like this).
5. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable.
6. The type of ground truth used: Not applicable.
7. The sample size for the training set: Not applicable (referring to clinical training data for performance, not engineering/software validation training).
8. How the ground truth for the training set was established: Not applicable.

Summary of Device Performance Claim Basis for Hair Growth:

The claim about promoting hair growth is based on:

• Substantial Equivalence: The primary strategy for clearance is demonstrating that the CurrentBody Skin Dual Light Hair Growth Helmet is substantially equivalent to legally marketed predicate devices (K231153: Neuhat Hair Growth System; K240456: Bosley Booster Laser Caps). The predicate devices were previously cleared for the same indication (promote hair growth in specific Norwood-Hamilton and Ludwig-Savin classifications with Fitzpatrick Skin Phototypes I-IV).
• Similarity in Design and Parameters: The submission highlights similarities in the intended use, indications for use, type of light (low-level laser and LED), wavelength (very close to predicates), number of diodes, energy per laser diode, and treatment time/irradiance (very close to predicates). The argument is that these similarities mean the subject device will have a similar therapeutic effect to the already-cleared predicate devices.
• Non-Clinical Data: As detailed in the table above, the non-clinical testing ensures the device meets safety standards (electrical, EMC, photobiological, battery, biocompatibility, software) which indirectly supports its safe use for its intended purpose without raising new questions of safety or effectiveness compared to the predicates.

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

   • Not applicable. No clinical performance studies were conducted or provided in this 510(k) submission to establish acceptance criteria for device performance or report device performance against such criteria. The "performance" assessment was primarily through comparison to predicate devices and non-clinical testing.

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. No clinical test set was used for performance evaluation in this 510(k).

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 clinical test set requiring expert ground truth was used for performance evaluation in this 510(k).

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

   • Not applicable. No clinical test set requiring adjudication was used for performance evaluation in this 510(k).

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 light-based therapy device, not an AI-powered diagnostic or assistive tool, and no MRMC study was conducted.

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

   • Not applicable. This device is a physical light-based therapy device, not an algorithm, and no standalone performance study was conducted.

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

   • Not applicable. No clinical ground truth was established as no clinical studies were performed. The "ground truth" for substantial equivalence was based on existing predicate device characteristics and regulatory standards.

8. The sample size for the training set:

   • Not applicable. This device is a physical light-based therapy device, not a machine learning model, and therefore does not have a "training set" in the context of AI/ML.

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

   • Not applicable. As above, no training set for an AI/ML model was used.

Summary of what was reported instead:

The 510(k) submission relied on:

• Non-Clinical Tests:
  • Electrical safety (e.g., IEC 60601-1, IEC 60601-1-11, IEC 60601-2-57, IEC 60601-1-2)
  • Photobiological safety (IEC 62471)
  • Battery safety (IEC 62133-2)
  • Biocompatibility (ISO 10993-5, ISO 10993-10, ISO 10993-23)
  • Software verification and validation (classified as "moderate" concern)
• Comparison to Predicate Devices: The document extensively compares the Solawave 2-in-1 Skincare Mini with several predicate and reference devices regarding features like intended use, regulation class, product code, power source, irradiance source, wavelengths, irradiances, and treatment time to establish substantial equivalence. The argument for equivalent "treatment effect (wrinkle treatment)" is made based on similar wavelengths, and irradiances/treatment times being "very close to those of reference devices 1 and 2."

In conclusion, for this specific 510(k), the acceptance criteria and proof of device performance were primarily established through substantial equivalence to existing legally marketed devices and successful completion of non-clinical safety testing, rather than through new clinical performance studies.

The CurentBody™LED 4 in 1 Zone Facial Mapping Mask is a home wearable light-emitting diode phototherapy device whose purpose is to produce an even, cool, narrow band of light for the treatment of mild to moderate acne vulgaris of the face. The system consists of a flexible silicone mask that contains LEDs and a controller. The mask is worn on the face and is held in place by adjustable Velcro straps. The mask compromises of 2 surfaces. An inner surface that contacts the skin and an outer surface, Both surfaces are constructed of silicone The CurentBody™LED 4 in 1 Zone Facial Mapping Mask has 4 models, MK-90C, MK-90M, MK66RB-F and MK-90N.The controller contains a rechargeable lithium battery. The user charges the controller by connecting the charging cable with an adapter (AC100-240V, 50Hz/60Hz 5V 2A).The LED Light Therapy Mask cannot be operated while charging.

This document describes the FDA's decision to clear the CurrentBody™ LED 4 in 1 Zone Facial Mapping Mask based on its substantial equivalence to previously marketed devices. As such, it does not include a detailed study proving the device meets acceptance criteria specific to a new AI/imaging algorithm. Instead, it relies on demonstrating that the new device is as safe and effective as existing, cleared devices through non-clinical testing and comparison.

Therefore, many of the specific questions about AI/imaging algorithm acceptance criteria, ground truth establishment, expert adjudication, and MRMC studies are not applicable to this 510(k) submission, which is for a light therapy device.

However, I can extract information related to the device's technical specifications and how its performance and safety were evaluated against predicate devices.

Here's a breakdown of the available information, addressing the relevant points and noting where information is not applicable due to the nature of the device and submission type:

1. Table of acceptance criteria and reported device performance:

The document doesn't present "acceptance criteria" in the traditional sense of a specified performance threshold (e.g., >X% accuracy). Instead, the acceptance criteria for this 510(k) submission are implicitly met by demonstrating substantial equivalence to predicate devices in areas of safety and effectiveness. The "reported device performance" is largely framed as compliance with recognized standards and similarity to the predicate devices.

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

• Sample Size: Not applicable. This submission relies on substantial equivalence through non-clinical performance and safety testing against recognized standards, and comparison to predicate devices, rather than a clinical trial with a "test set" of patients.
• Data Provenance: Not applicable in the context of patient data. The provenance of the testing data would be from the manufacturer's internal labs or contracted testing facilities for engineering, electrical, and biocompatibility tests.

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

• Not applicable. This device is not an AI/imaging algorithm that requires ground truth established by experts for a test set. Its performance relies on physical specifications, light output, electrical safety, and biocompatibility, as measured against engineering standards.

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

• Not applicable. There is no "test set" of patient cases requiring adjudication by experts.

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 a light therapy device, not an AI-assisted diagnostic tool.

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 for diagnostic or interpretative performance.

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

• Not applicable. "Ground truth" in the context of clinical outcomes or imaging interpretation is not relevant here. The "ground truth" for this device's safety and effectiveness is established through adherence to recognized international and electrical safety standards (e.g., IEC 60601 series, IEC 62471, ISO 10993 series) and demonstration that its physical and functional characteristics are "substantially equivalent" to already cleared predicate devices.

8. The sample size for the training set:

• Not applicable. The device is not based on a machine learning model that requires a training set.

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

• Not applicable. The device is not based on a machine learning model that requires ground truth for a training set.

Summary of Study Type:

The "study" that proves this device meets the "acceptance criteria" (defined as substantial equivalence to predicates and compliance with safety standards) is a non-clinical performance and safety testing program, as outlined in section 5.1 and 5.2 (Non-Clinical Test, Biocompatibility Test, Light output, and Software verification and validation). No clinical studies were deemed necessary for this 510(k) submission, as stated in section 5.5. The performance is assessed through technical specifications and their adherence to established safety and performance norms for similar devices.
