The provided FDA 510(k) clearance letter and summary for the KALA Therapy Wand (Model: KALA-03) primarily focus on demonstrating substantial equivalence to predicate devices through non-clinical testing. This type of clearance generally does not require extensive clinical performance studies with detailed acceptance criteria and human reader studies as would be seen for a new or complex AI/ML-driven diagnostic device.

Based on the provided information, the device is a light-based therapy device for over-the-counter use, intended for aesthetic purposes (facial wrinkles and mild to moderate inflammatory acne). The "study" proving the device meets acceptance criteria is a non-clinical performance testing approach demonstrating compliance with relevant electrical safety, electromagnetic compatibility, photobiological safety, battery safety, and biocompatibility standards. Software verification and validation, and usability validation were also performed.

Here's the breakdown of the information requested, as extractable from the provided document:

Acceptance Criteria and Device Performance

Since this is a non-clinical submission, the "acceptance criteria" are compliance with established safety and performance standards. There isn't a table of statistical performance metrics, but rather successful adherence to defined technical and safety requirements.

Table of Acceptance Criteria and Reported Device Performance (Non-Clinical Compliance)

Study Details (as applicable for a non-clinical submission):

1. Sample sizes used for the test set and the data provenance:

   • Test Set (Device Testing): The "test set" here refers to the device prototypes/units that underwent the non-clinical tests. The document does not specify the number of units tested for electrical safety, EMC, etc., which is typical for such submissions.
   • Data Provenance: The testing was conducted by or for the manufacturer (Shenzhen Kaiyan Medical Equipment Co., Ltd) in China, as indicated by the submitter's information. It's inherently "prospective" in the sense that the tests were performed on the device designed for submission.

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

   • This is a non-clinical submission for a device used for aesthetic purposes. The concept of "ground truth" established by medical experts (like radiologists for image analysis) is not applicable here. The "ground truth" for these tests is defined by the passing criteria of the international standards themselves (e.g., specific thresholds for electrical leakage, EMC emissions, irradiance, etc.). Compliance is assessed by qualified test engineers and labs.

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

   • Not applicable. Adjudication methods are typically used in clinical studies, especially those involving subjective assessments or disagreements among human readers. Non-clinical testing against objective standards does not involve expert adjudication in this manner.

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:

   • No. An MRMC study is not relevant for this type of aesthetic, light-based therapy device where the claim is not for assisting human readers in diagnosis. The clearance is based on safety and functional equivalence.

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

   • Not applicable. This device is not an algorithm for diagnosis or image analysis. It is a physical device providing light therapy. Its "standalone" performance refers to its ability to meet the specified technical parameters and safety standards.

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

   • The "ground truth" for demonstrating substantial equivalence and safety in this context is compliance with recognized international consensus standards (e.g., IEC, ISO). The performance is measured against these technical specifications, not against clinical outcomes or expert consensus on medical conditions.

7. The sample size for the training set:

   • Not applicable. This device does not involve a machine learning algorithm that requires a "training set" in the traditional sense of AI/ML software. The software component, as described, is for controlling device functions ("Basic Documentation Level software"), not for learning from data.

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

   • Not applicable, as there is no training set for an AI/ML algorithm.

The VMAP PRO is intended for relief of minor muscle aches and pains, temporary increase in local blood circulation and activation of connective tissue.

The VMAT PRO is a pressure pulse device that creates pneumatically generated pressure pulses caused by compressed air delivering ballistic projectile through a handpiece coming into contact with the skin. VMAT PRO is equipped with one handpieces that includes four transmitters [VAT120 (diameter of 20mm), VAT220 (diameter of 20mm), VAT215 (diameter of 15mm), and VAT 135 (diameter 35mm)] that allow radial treatments, ergonomically designed to allow the user to work in various areas of the body. To facilitate the movement of the transmitter on the skin, and guarantee a correct contact, an ultrasound gel FDA cleared should be used (i.e. Aquasonic 100 Ultrasound Transmission Gel K802146).

The provided text is a 510(k) Summary for the VMAT PRO device, seeking substantial equivalence to a predicate device (D-Actor 200 Vibration Massage System). It focuses on demonstrating that the new device is as safe and effective as the legally marketed predicate. However, this document does not describe a study involving human readers, AI assistance, or the establishment of ground truth by multiple experts for a test set.

The closest information provided is about performance testing to establish that the VMAT PRO control unit performs as intended, and a comparison of its technological characteristics with the predicate device.

Therefore, I cannot fully address all the points in your request as the information is not present in the provided document. I will fill in what can be inferred and explicitly state where information is missing.

Here's an analysis based on the provided document:

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

The document does not explicitly state "acceptance criteria" in the format of a threshold that must be met. Instead, it aims to demonstrate "substantial equivalence" to a predicate device. The performance is assessed by comparing various technical specifications. The acceptance criterion is implicit: the device's performance characteristics must be sufficiently similar to the predicate device, or any differences must not impact safety or efficacy.

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

This document describes technical and performance testing of the device itself (e.g., electrical safety, EMC, acoustic characteristics), not a clinical study or a study involving a "test set" of patient data for AI evaluation. Therefore, this information is not applicable to this 510(k) summary. The testing refers to the device unit's performance, not a dataset.

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. This document does not concern an AI/clinical diagnostic device requiring expert adjudicated ground truth. The "ground truth" for the device's technical specifications is established through engineering and physical measurements according to international standards (IEC).

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

Not Applicable. As no diagnostic test set is used, no adjudication method is relevant.

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

No. The document explicitly states: "Clinical Evidence – N/A. No clinical studies were conducted as part of this submission." Therefore, no MRMC study was performed.

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

No. This is not an AI algorithm but a physical therapeutic device. The "performance testing" described refers to the device's physical and electrical characteristics as per IEC standards, not an algorithm's output.

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

For the technical characteristics comparison, the "ground truth" is derived from:

• Engineering measurements and specifications of the VMAT PRO device itself, conducted in a laboratory setting (e.g., "measured in a laboratory, using ultrasound" for applicator displacement).
• Published specifications of the predicate device (D-Actor 200) from its own 510(k) submission or technical documentation.
• Adherence to international standards such as IEC 60601-1, IEC 60601-1-2, and IEC 63045:2020 for safety, EMC, and ultrasonic characteristics.
• Biocompatibility testing according to ISO 10993-1:2018.

For the purpose of this 510(k) submission, the "ground truth" is primarily device-centric technical specifications and compliance with recognized standards, not clinical diagnostic outcomes or human expert interpretations of patient data.

8. The sample size for the training set

Not Applicable. This is not an AI/machine learning device; therefore, there is no "training set."

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

Not Applicable. As there is no training set.

This document is a 510(k) summary for the Indiba S.A.U. Reverso Pro System (K243139). It details the device's technical specifications, indications for use, and a comparison to predicate devices to establish substantial equivalence.

Based on the provided text, the device in question is an electrosurgical cutting and coagulation device. The information provided outlines the non-clinical (bench) performance data for the device, and a qualitative assessment of its similarities to predicate devices to establish substantial equivalence. However, there is no detailed clinical study or acceptance criteria table in the format requested, nor is there information about AI/ML algorithm performance.

The document states:

• "Clinical Performance Data: Not Applicable" (Page 8)
• The "Non-Clinical (Bench) Performance Data" section primarily discusses the device's RF performance specifications and thermal effects. It does not describe a study involving human or expert evaluation for determining accuracy or clinical efficacy in the context of an AI/ML device.
• The entire submission focuses on establishing substantial equivalence to predicate devices based on technological characteristics and safety standards, rather than proving the device meets specific performance criteria through a rigorous clinical trial or AI/ML validation study.

Therefore, I cannot provide a detailed answer to your request regarding acceptance criteria and a study proving the device meets them, specifically for an AI/ML algorithm with human-in-the-loop performance, ground truth establishment, or sample sizes for test/training sets, because this submission is for a medical device that does not appear to involve an AI/ML component or a clinical performance study in the way typically required for AI/ML-driven devices.

The information provided relates to the physical device's electrical and mechanical safety, electromagnetic compatibility, and thermal performance.

Based on the provided text, the device is a radiofrequency aesthetic device, not an AI/ML-driven diagnostic or therapeutic device. As such, the types of studies and acceptance criteria you've asked about (e.g., sample size for test set, number of experts for ground truth, MRMC studies, standalone algorithm performance) are not applicable to the information presented in this 510(k) summary. The "study" mentioned for performance is a skin temperature test on 3 human volunteers for the Quadro RF Applicator, which is a very different type of study than an AI/ML validation.

Therefore, providing a specific table and detailed answers to your questions on AI/ML performance would be misleading as the document does not contain this information.

Breo Laser Hair Growth Comb is a hand-held comb-shaped low level laser therapy device that emits laser light designed to promote hair growth in women and men. The device provides distributed laser light to the scalp while the comb teeth simultaneously part the user's hair to ensure the laser light reaches the user's scalp. The device also has a massage function which is a mechanical vibration function.

This document is a 510(k) Premarket Notification from the FDA for a medical device called the "Breo Laser Hair Growth Comb (Scalp 3L)". It primarily focuses on demonstrating substantial equivalence to a predicate device, rather than providing detailed clinical study results with specific acceptance criteria and performance metrics for a novel AI/medical device.

Therefore, many of the requested elements for describing acceptance criteria and a study proving a device meets them (especially those related to AI algorithm performance or direct clinical efficacy studies with specific metrics) are not present in the provided text. The document states "Clinical study: Not applicable" (Section 9), indicating that a clinical trial to prove efficacy or safety in the traditional sense was not required for this 510(k) clearance due to the device's similarity to an already cleared predicate.

Here's what can be extracted and what cannot:

Acceptance Criteria and Device Performance (Based on Substantial Equivalence)

The acceptance criteria here are implicitly met by demonstrating substantial equivalence to a predicate device (Laser Therapy Hair Growth Comb, Lasercomb-001, K230134). This means the device performs similarly in terms of its technical specifications and intended use.

Study Details (Based on the Provided Document)

As noted, the document explicitly states "Clinical study: Not applicable." The demonstration of the device meeting acceptance criteria is primarily through the comparison of technical specifications and safety standards compliance to a legally marketed predicate device. Therefore, many standard questions about AI/medical device study design are not applicable here.

1. Sample size used for the test set and the data provenance: Not applicable. No clinical test set data is described for efficacy. Safety testing (biocompatibility, electrical safety, EMC) is done on the device itself, not on a human population test set for efficacy.
2. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. No clinical ground truth establishment is described for a test set.
3. Adjudication method (e.g. 2+1, 3+1, none) 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 not an AI-assisted diagnostic or therapeutic device that involves human readers.
5. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable. This is not an algorithm-only device.
6. The type of ground truth used (expert consensus, pathology, outcomes data, etc.): Not applicable for effectiveness/clinical performance. For safety and functional performance, the "ground truth" is compliance with established international standards (IEC, ISO) and the comparable performance of the predicate device.
7. 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 requiring such.
8. How the ground truth for the training set was established: Not applicable.

The ShockPhysio Mobile (model SW3200 Basic) is indicated for:

• Relief of minor muscle aches and pains
• Temporary increase in local blood circulation
• Activation of connective tissue

Not Found

This document is a 510(k) clearance letter from the FDA for a therapeutic massager, the "ShockPhysio Mobile (model SW3200 Basic)".

It does not contain any information regarding acceptance criteria, device performance, sample sizes, expert involvement, ground truth establishment, or specific study details like those expected for AI/software-based medical devices.

The letter explicitly states: "We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976...". This indicates a substantial equivalence (SE) determination, which often relies on demonstrating that the new device is as safe and effective as a legally marketed predicate device, rather than requiring extensive de novo clinical trials or performance studies against specific acceptance criteria.

Therefore, I cannot provide the requested table and study information based on the provided text. The document is for a Class I Therapeutic Massager (a device with lower regulatory controls), and the FDA clearance process for such devices often focuses more on substantial equivalence to existing devices and adherence to general controls, rather than complex performance studies.

The GENEO X ELITE system with the OxyGeneo Applicator is intended to provide massage by a mechanical vibration of an electrically powered applicator. The OxyGeneo treatment is suitable for all skin types.

The GENEO X ELITE device is a non-invasive, tabletop console with a graphical user interface (GUI), which supports two applicator types: the TriPollar Radiofrequency (RF) Applicator utilizing bipolar radiofrequency technology for facial wrinkles treatments and the OxyGeneo Applicator utilizing mechanical vibration for facial massage sensation.

The GENEO X ELITE device is manufactured by Pollogen Ltd. Similar to the predicate device, the STOP U Model UXV device, the GENEO X ELITE device constitutes the same underlying TriPollar technology to employ bipolar RF energy in a non-invasive manner utilizing the TriPollar RF Applicator.

In addition to the TriPollar RF applicator the GENEO X ELITE device comprises the OxyGeneo Applicator. The OxyGeneo Applicator is an electrically powered massager utilizing mechanical vibration generated by an electrically powered motor housed in the applicator.

The provided document is a 510(k) summary for the Pollogen Ltd. GENEO X ELITE device and does not contain detailed information about specific acceptance criteria or a dedicated study setup to prove device performance against those criteria in the way typically found for AI/ML devices.

However, based on the non-clinical and clinical performance data sections, and the general context of a 510(k) submission for an electrosurgical device, we can infer some "acceptance criteria" based on compliance with recognized standards and successful completion of various tests related to safety and functionality. The study described is primarily a Human Factors (Usability) study and various bench performance tests, rather than a clinical efficacy study with quantitative performance metrics.

Here's an attempt to structure the information based on your request, with the understanding that direct quantitative acceptance criteria and corresponding performance from a single study are not explicitly detailed for clinical efficacy in this document.

1. Table of Acceptance Criteria and Reported Device Performance

As the document is a 510(k) summary focused on substantial equivalence rather than a detailed clinical trial report, specific quantitative acceptance criteria for clinical effectiveness (e.g., specific reduction in wrinkle severity) and their statistically proven performance are not explicitly stated. Instead, "acceptance criteria" are inferred from compliance with recognized safety and performance standards and successful completion of bench and human factors testing.

2. Sample Sizes Used for Test Set and Data Provenance

• Human Factors Validation Testing (Phase II):
  • Sample Size: The document does not explicitly state the number of participants (users or cases) in the Human Factors Validation Testing (Phase II). It only mentions that the study involved "use of the device by the device target users (estheticians / cosmeticians) and performing device operation and knowledge tasks."
  • Data Provenance: The document states that the GENEO X Human Factors (Usability) validation test further validated the device "in a real-world environment." Phase I (formative assessment) was performed "on the GENEO X TriPollar RF device (precursor to the GENEO X) in the EU (Belgium and Switzerland) and Canada." The Phase II validation study's specific location is not detailed beyond "real-world environment." This study is prospective, as it involves testing with target users.

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

• For the Human Factors Validation Testing, "ground truth" would relate to the assessment of usability and the effectiveness of training materials. The document implies that "target users (estheticians / cosmeticians)" performed the tasks and their performance/feedback constituted the data for assessing usability. No explicit mention of independent "experts" establishing a separate "ground truth" for usability, outside of the direct user experience and observation during the study, is made.

4. Adjudication Method for the Test Set

• The document does not describe a clinical performance study with an adjudication method (like 2+1, 3+1). The Human Factors study's assessment method is not detailed in terms of adjudication.

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

• No MRMC comparative effectiveness study is described for clinical efficacy. The Human Factors study is not an MRMC study for clinical outcomes, but rather for usability. The document focuses on substantial equivalence to a predicate device based on similar technology, safety, and performance, not on demonstrating improved effectiveness over human readers or other devices.

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

• This device is an electrosurgical device for aesthetic use, involving a human operator (esthetician/cosmetician). It is not an AI/ML diagnostic or predictive algorithm, so the concept of "standalone performance" for an algorithm without human-in-the-loop does not apply in the typical sense. The device's operation inherently involves a human user.

7. Type of Ground Truth Used

• For Bench Performance Data: The "ground truth" for technical specifications (e.g., RF output power, frequency, electrical safety) is established by measurements against recognized international standards (e.g., IEC 60601-1, IEC 60601-1-2, IEC 60601-2-2).
• For Human Factors Validation Testing: The "ground truth" is derived from user performance, observations, and feedback from the device's target users (estheticians/cosmeticians) as they interact with the device and training materials in a simulated real-world environment.

8. Sample Size for the Training Set

• This document does not describe an AI/ML device in the context of a "training set" for an algorithm that learns from data. Therefore, the concept of a training set sample size is not applicable. The device design and safety features are based on engineering principles and compliance with standards, not machine learning training.

9. How Ground Truth for the Training Set Was Established

• Not applicable, as there is no "training set" in the context of an AI/ML algorithm learning.

Ask a specific question about this device

BTL-094 is indicated to be used for:

• Relief of minor muscle aches and pains.
• Temporary increase in local blood circulation.
• Activation of connective tissue.

The BTL-094 is a non-invasive therapeutic device, which uses acoustic waves in order to stimulate a local biological response in the treated tissue.

The BTL-094 generates extracorporeally induced massage pulses to stimulate a local biological response in the treated tissue. The main source of acoustic waves is a piezo transducer inside the applicator. The energy transfer from the piezo transducer to the treated tissue is realized via coupling pad.

The main unit is equipped with a color touch screen, which considerably simplifies its operation. The onscreen information guides the user step through the entire therapy process. A secondary screen is placed on the applicator for the presentation of the actual state of main therapy parameters. The therapeutic parameters are adjustable via touch-screen, buttons and knob. The user is able to set following therapy parameters: intensity, frequency and number of shocks.

The provided text describes a 510(k) premarket notification for the BTL-094 therapeutic massager, which is a Class I device. The focus of the document is to demonstrate "substantial equivalence" to legally marketed predicate devices, rather than establishing new performance criteria through a clinical study. Therefore, a direct 'acceptance criteria' and 'reported device performance' based on a clinical study for the BTL-094 device itself are not applicable as per the document.

The document explicitly states: "Clinical Testing: Not applicable" on page 5. This indicates that no clinical study was performed or required for this 510(k) submission to assess the device's performance against specific acceptance criteria.

Instead of a clinical study, the submission relies on demonstrating that the BTL-094 device has "technological characteristics" (on pages 6-11) that are substantially equivalent to those of two predicate devices: D-Actor 200 (K173692) and DolorClast® Radial (K220538). The "acceptance criteria" in this context are implicitly that the technological characteristics of the BTL-094 are comparable enough to the predicates that they do not raise new questions of safety or effectiveness.

Here's an analysis based on the information provided, addressing your points where applicable:

As no clinical study was conducted for the BTL-094 to establish new acceptance criteria and measure its performance against them, a direct table for this is not available in the document. The acceptance for this submission is based on the comparison of the BTL-094's technological characteristics to those of the predicate devices. The table below summarizes key comparative information presented in the document, which serves as the basis for the declaration of substantial equivalence.

Comparison of BTL-094 to Predicate Devices (Basis for Substantial Equivalence)

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

Not Applicable. As stated, "Clinical Testing: Not applicable." No test set of patient data was used for a clinical study to prove the device meets acceptance criteria. The submission relies on non-clinical testing (safety and performance standards, biocompatibility) and a comparison of technological characteristics to existing predicate devices.

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

Not Applicable. No clinical test set requiring expert ground truth establishment was used.

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. The device is a therapeutic massager, not an AI-assisted diagnostic tool.

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

Not Applicable. The device is a physical therapeutic massager, not an algorithm.

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

Not Applicable. No clinical performance study was conducted that would require a ground truth based on patient data. The "ground truth" for this 510(k) submission, in a broad sense, is the demonstration of adherence to recognized safety standards and the established safety and effectiveness profiles of the legally marketed predicate devices through a comparison of technological attributes.

8. The sample size for the training set

Not Applicable. No training set of data was used, as no artificial intelligence or machine learning component is described for this device.

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

Not Applicable. There was no training set mentioned in the provided document.

In summary, the provided document is a 510(k) premarket notification that demonstrates substantial equivalence based on non-clinical testing (compliance with recognized safety and performance standards like IEC 60601 series and ISO 14971/10993 for electrical safety, EMC, usability, and biocompatibility) and a detailed comparison of the device's technological characteristics to those of two legally marketed predicate devices. The absence of clinical testing is explicitly stated, indicating that the FDA determined it was not necessary for this type of device and submission pathway.
