    Device Description

    The Neurotech Plus is a portable, two-channel; battery operated system which can provide both Neuromuscular Electrical Stimulation (NMES) and Transcutaneous Electrical Nerve Stimulation (TENS). The device is intended be available by prescription only. Included with the Neurotech Plus control unit, are a lead wire assembly, electrodes and instructions for use.

    The Neurotech Plus contains ten program sets which have been each allocated an individual type number. Seven of these types offer a combination of NMES and TENS programs. There are two types which offer only NMES programs and one which has only TENS programs.

    The lead-wire assembly contains the ID chip (EEPROM) that identifies the required program set. Each of the program set options are pre-programmed during manufacturing and no access to the configuration is available to either the end user or clinician. When each lead wire is connected to the unit and the outputs (A, B, C or D) to the electrodes, the two channels may be operated independently through the unit. Detailed diagrams for correct device usage and placement of the electrodes are available as part of the instructions for use.

    AI/ML Overview

    This is a 510(k) premarket notification for a medical device (Neurotech Plus, Type 413) and, as such, it does not describe an acceptance criteria study in the way one might for an AI/ML device or software performance. This document focuses on demonstrating substantial equivalence to predicate devices based on technological characteristics and intended use, rather than presenting a performance study with acceptance criteria and results.

    However, I can extract information related to the device's characteristics and the comparison made to establish substantial equivalence, which is a form of meeting "acceptance criteria" in the context of a 510(k):

    1. Table of Acceptance Criteria and Reported Device Performance

    In a 510(k) submission, "acceptance criteria" is not explicitly stated as performance metrics like sensitivity/specificity for a diagnostic AI. Instead, substantial equivalence is established by demonstrating that the new device has the same intended use and similar technological characteristics to a legally marketed predicate device, or that any differences do not raise new questions of safety or effectiveness. The "reported device performance" is essentially the detailed technical specifications of the Neurotech Plus and how they compare to the predicate devices.

    The tables (7.1 through 7.10) in the document provide a detailed comparison of the Neurotech Plus models with their respective predicate devices across various electrical stimulation parameters. These comparisons serve as the basis for demonstrating that the new device performs "as well as or better than" the listed predicate.

    Below is an example of an abstracted table, as the original tables (7.1-7.10) are extensive and detailed for each model. I will use the information from Table 7.1 for Model 431 as an example comparison, highlighting how the new device's parameters compare to the predicate devices.

    Abstracted Comparison Table (Example for Neurotech Plus Model 431 vs. Predicates)

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

    The document explicitly states: "No new clinical tests have been submitted as part of this premarket notification." Therefore, there is no "test set" in the context of patient data, nor is there information on sample size or data provenance from a prospective or retrospective study. The primary "test" for this submission is a comparison of engineering specifications against predicate devices.

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

    Since no new clinical tests were conducted and no patient-specific "test set" was used, there were no experts involved in establishing a "ground truth" for such a test set. The "ground truth" for a 510(k) is implicitly the established safety and effectiveness of the predicate devices.

    4. Adjudication Method for the Test Set

    Not applicable, as no new clinical test set requiring adjudication was used.

    5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, and Effect Size

    Not applicable. This is a 510(k) for a TENS/NMES device, not an AI/ML diagnostic or treatment assistance software. No MRMC study was performed.

    6. If a Standalone (Algorithm Only Without Human-in-the-Loop Performance) Was Done

    Not applicable. This is a hardware medical device (Neurotech Plus, Type 413), not a standalone algorithm.

    7. The Type of Ground Truth Used

    In the context of a 510(k), the "ground truth" for demonstrating safety and effectiveness relies on the previously established regulatory clearance of the predicate devices. The technological characteristics and intended use of the Neurotech Plus were compared to these already approved devices. The ground truth is effectively the regulatory precedent set by the predicate devices.

    8. The Sample Size for the Training Set

    Not applicable, as this is not an AI/ML device and therefore does not involve a training set.

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

    Not applicable, as there is no training set for this type of device submission.

    Intended Use

    BMR Face is intended for facial stimulation and is indicated for over the counter cosmetic use

    Device Description

    BMR Face. Type 371/372* (* Type 372 is simply a black version of Type 371) is a twochannel, battery operated cosmetic device which is intended for use on the face. The device consists of a rechargeable electronic device which connects to an applicator. Each side paddle of the applicator contains a set of replaceable twin conductive gel pads which deliver electrical impulses to the face. The BMR Face device operates by applying Transcutaneous Electrical Nerve Stimulation (TENS) to the facial area. Low-level electrical impulses are sent from the stimulator unit via an applicator to gel pads that are positioned anterior to each ear and strategically over the cranial nerve #7 of the face, 3 programs are available to the user and these vary in treatment times from 10 to 20 minutes. Power is derived from a 3.6V NiMH rechargeable battery pack that is pre-installed in the unit and there is no capability for charging the unit whilst any treatment is ongoing. All internal connections of the unit are over molded to prevent moisture ingress.

    AI/ML Overview

    The provided text describes a 510(k) submission for the "BMR Face, Type 371 & Type 372" device. It focuses on demonstrating substantial equivalence to a predicate device ("Rejuvenique® System") rather than presenting a study to prove the device meets specific acceptance criteria for performance in a clinical outcome.

    Therefore, the document does not contain the information requested regarding acceptance criteria and a study proving the device meets them in the context of clinical effectiveness or performance as an AI/ML device.

    Here's a breakdown of why this information isn't available in the provided text:

    • Device Type: This is a physical, electrical stimulator, not an AI-powered diagnostic or therapeutic device. The submission is for a medical device seeking clearance based on substantial equivalence to a legally marketed predicate device.
    • Focus of the Submission: The 510(k) submission primarily focuses on comparing the technological characteristics of the new device to the predicate device to demonstrate that it is as safe and effective. It highlights aspects like intended use, indications for use, anatomical site utilized, energy used, materials, biocompatibility, electrical safety, mechanical safety, and adherence to various electrical and safety standards.
    • Absence of Clinical Performance Data: The document explicitly states: "Clinical Tests: No new clinical studies have been submitted as part of this Premarket Notification." This confirms that no studies were conducted to measure specific performance metrics (like sensitivity, specificity, accuracy, etc.) against acceptance criteria for a clinical outcome.
    • "Acceptance Criteria" in this context: The "acceptance criteria" here refer to the regulatory requirements and standards the device must meet (e.g., IEC 60601-1 for electrical safety, ISO 10993 for biocompatibility) to be deemed substantially equivalent and safe for marketing, not performance metrics related to a diagnostic or therapeutic outcome.

    Based on the provided text, I cannot complete the requested tables and information because the document does not present a study proving the device meets performance-based acceptance criteria in the way typically expected for AI/ML devices or studies evaluating clinical effectiveness metrics.

    The text only provides a summary of non-clinical tests demonstrating compliance with safety standards and a comparison of technological characteristics to a predicate device.

    It's important to note that the provided documentation is a 510(k) Premarket Notification for a medical device. This type of submission focuses on demonstrating substantial equivalence to a previously legally marketed device (predicate device), rather than a full de novo clinical trial proving efficacy and safety from scratch.

    Therefore, the "acceptance criteria" here are primarily about demonstrating that the new device is as safe and effective as the predicate device, not necessarily defining specific performance metrics for muscle tone improvement. The "study that proves the device meets the acceptance criteria" refers to the entire 510(k) submission process, which relies on demonstrating equivalence rather than a dedicated clinical trial for performance.


    1. Table of Acceptance Criteria and Reported Device Performance

    Acceptance Criteria (Demonstrated Equivalence to Predicate)Reported Device Performance (as demonstrated in submission)
    Intended Use: Same intended use as predicate device"The Flex Max by Slendertone device has the same intended use and indications for use as the listed equivalent legally marketed device. It is intended for use by healthy persons to apply transcutaneous neuromuscular electrical stimulation ('NMES') through skin contact electrodes for the purpose of improving abdominal muscle tone, strength and firmness."
    Indications for Use: Same indications as predicate"Flex Max by Stendertone is indicated for the improvement of abdominal muscle tone, for strengthening of the abdominal muscles and for the development of a firmer abdomen."
    Technological Characteristics: Substantially equivalent to predicate"The Flex Max by Slendertone device is identical to the predicate device in design, materials, mode of operation, and methods of manufacture. It differs only in the addition of different program offerings to the user."
    Safety: Compliance with relevant electrical safety and EMC standards"The Flex Max by Slendertone complies with international standards for electrical safety and electromagnetic compatibility."
    Effectiveness: Inferred from equivalence to predicateImplied to be equivalent to the predicate device's effectiveness through the demonstration of identical design, materials, mode of operation, and methods of manufacture.

    Explanation of "Acceptance Criteria" in this context: For a 510(k) submission, the primary "acceptance criterion" is to demonstrate substantial equivalence to a predicate device. This means showing that the new device has the same intended use, indications for use, and similar technological characteristics, and that any differences do not raise new questions of safety or effectiveness. The device met this acceptance criterion, as indicated by the FDA's "substantial equivalence" determination.


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

    • Sample Size for Test Set: Not applicable in the context of a new clinical study. The submission primarily relies on the established safety and effectiveness of the predicate device (Slendertone Flex, Type 515, K030708). No new clinical "test set" data from human subjects is provided beyond proving the new device's equivalence to the predicate.
    • Data Provenance: Not applicable. No new human data is presented in this submission. The basis for equivalence is drawn from the predicate device’s prior clearance.

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

    • Number of Experts: Not applicable. No "ground truth" was established for a new clinical test set in this submission.
    • Qualifications of Experts: Not applicable.

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

    • Adjudication Method: Not applicable. No clinical test set requiring adjudication was performed as part of this 510(k) submission.

    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

    • MRMC Study: No. This is a muscle stimulator device, not an imaging/diagnostic device that would typically involve human "readers" or AI assistance in that sense.
    • Effect Size of Human Readers with/without AI: Not applicable.

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

    • Standalone Performance: Not applicable. This device is a muscle stimulator, not an algorithm. Its operation inherently involves a human user applying it.

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

    • Type of Ground Truth: The "ground truth" in this context is the FDA's prior determination of safety and effectiveness for the predicate device. The submission's "proof" relies on demonstrating that the new device is functionally identical or equivalent to this already cleared predicate device. There is no new clinical outcomes data or pathology presented for the Flex Max.

    8. The sample size for the training set

    • Sample Size for Training Set: Not applicable. This is not an AI/machine learning device that requires a training set.

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

    • Ground Truth for Training Set: Not applicable.

    Summary of the Study:

    The "study" described in the provided document is a 510(k) Premarket Notification submission, not a clinical trial. The manufacturer's strategy was to demonstrate substantial equivalence to a previously cleared predicate device (Slendertone Flex, Type 515, K030708).

    • Key Argument: The device is "identical to the predicate device in design, materials, mode of operation, and methods of manufacture," differing only in "the addition of different program offerings to the user."
    • Clinical Testing: "No additional clinical studies were provided as part of this submission." This indicates that the manufacturer relied entirely on the established safety and effectiveness of the predicate device and the similarity of the new device to the predicate, along with compliance with international electrical safety and electromagnetic compatibility standards.
    • Ground Truth: The "ground truth" for the overall acceptance of the device is rooted in the FDA's previous clearance of the predicate device. By demonstrating substantial equivalence, the new device is deemed to carry the same safety and effectiveness profile as the predicate.

    In essence, the "study" for this 510(k) submission primarily involved a technical comparison and regulatory compliance assessment to demonstrate that the Flex Max by Slendertone is sufficiently similar to an already approved device, making new clinical performance data unnecessary for its market clearance.
