AI/ML Overview

The provided document is a 510(k) Premarket Notification from the FDA, asserting the substantial equivalence of the "Wrap Accessory Electrodes" to legally marketed predicate devices. This type of submission relies on demonstrating that a new device is as safe and effective as an already cleared device, rather than proving absolute safety and effectiveness through extensive clinical trials.

As such, the document does not describe acceptance criteria for an AI/ML powered device, nor does it detail a study proving the device meets such criteria. The device in question is a passive accessory (electrodes) used with electrical stimulating devices, not an AI/ML powered medical device. Therefore, the questions related to AI/ML specific acceptance criteria, ground truth establishment, expert adjudication, MRMC studies, and standalone algorithm performance are not applicable to this document.

However, based on the provided text, we can extract information regarding the non-clinical testing performed to establish substantial equivalence.

Here's an analysis of the "study" (non-clinical testing) from the document's perspective:

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

The document doesn't present a formal table of "acceptance criteria" for performance in the typical sense of AI/ML metrics (e.g., sensitivity, specificity, AUC). Instead, it shows a comparison to predicate devices and lists various electrical performance parameters. The "acceptance criteria" are implied to be that the proposed device performs similarly to or within acceptable ranges of the predicate devices for safety and basic electrical functionality.

Acceptance Criteria (Implied)	Reported Device Performance (Proposed Device)
General Equivalence to Predicate Devices:
- Classification Product Code (GXY)	GXY (Same as Predicate)
- Regulation (21 CFR 882.1320)	21 CFR 882.1320 (Same as Predicate)
- Classification Name (Electrode, Cutaneous)	Electrode, Cutaneous (Same as Predicate)
- Class (2)	2 (Same as Predicate)
- Prescription or OTC	OTC (Same as Predicate)
- Intended Use (Deliver stimulation signals from legally marketed electrical stimulating devices to body surface)	Proposed device is intended to be used with legally marketed electrical stimulating devices (TENS or powered muscle stimulators) to deliver stimulation signals to the body surface. Expanded body areas (abdomen, leg, ankle, foot) compared to Predicate 1, but this difference "does not raise new questions of safety and effectiveness" as TENS/EMS are effective in other body areas.
Safety and Performance Characteristics:
- Biocompatibility (Compliance with ISO 10993-1)	Compliance with ISO 10993-1, ISO 10993-10, ISO 10993-23. (Same as Predicate)
- Impedance per area (comparable to predicate performance)	12.5 Ω/in.². Not directly compared to a predicate value, but stated that "Maximum Average Current Density" and "Maximum Peak Power Density" are similar, referencing IEC60601-2-10 and "Guidance Document for Powered Muscle Stimulator 510K Section 3." The difference in impedance does not raise new questions of safety or effectiveness.
- Electrical Performance Parameters	Maximum Output Voltage: - 500Ω: TENS 1:112, TENS 2: 114, STIM1:116, STIM2:116, STIM3:76, STIM4: 70 V - 2kΩ: TENS 1: 250, TENS 2: 240, STIM1: 250, STIM2: 250, STIM3: 158, STIM4: 146 V - 10kΩ: TENS 1: 300, TENS 2: 286, STIM1: 310, STIM2: 308, STIM3: 278, STIM4: 276 V Maximum Output Current: - 500Ω: TENS 1: 224, TENS 2: 228, STIM1: 232, STIM2: 232, STIM3: 152, STIM4: 140 mA - 2kΩ: TENS 1:125, TENS 2: 120, STIM1: 125, STIM2: 125, STIM3:79, STIM4: 73 mA - 10kΩ: TENS 1: 30, TENS 2: 28.6, STIM1: 31, STIM2:30.8, STIM3: 27.8, STIM4: 27.6 mA Pulse period: 20~200 mSec Frequency: - TENS 1: 33, TENS 2: 5, STIM1:37, STIM2:25, STIM3: 5, STIM4: 50 Hz Maximum Phase Charge (500Ω): - TENS 1: 11, TENS 2: 11, STIM1: 11.4, STIM2: 10.6, STIM3: 22.8, STIM4: 20.4 µC Maximum Charge Density (500Ω): - TENS 1: 0.024, TENS 2: 0.01, STIM1:0.027, STIM2: 0.021, STIM3: 0.021, STIM4: 0.059 mA/cm² Maximum Average Power Density (500Ω): - TENS 1: 1.33, TENS 2: 0.554, STIM1: 1.54, STIM2: 1.13, STIM3: 0.793, STIM4: 2.01 mW/cm²

- Hot spot test	Conducted (results not detailed but stated to meet predefined acceptance criteria).
- Maximum/Minimum resistance value	Conducted (results not detailed but stated to meet predefined acceptance criteria).

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

Sample Size: Not explicitly stated as a "sample size" in the context of a clinical test set. The testing refers to individual units of the Wrap Accessory Electrodes for non-clinical performance and safety evaluations. The document implies a sufficient number of devices were tested to draw conclusions on performance and safety compliance.
Data Provenance: The testing was conducted by Gymmax Technology Shenzhen Co., Ltd., which is based in China. The data would be from laboratory testing of the physical devices. This is not a retrospective or prospective human data study in the medical sense.

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

Not applicable. This is not a study assessing diagnostic performance where expert ground truth is required. The "ground truth" for these tests are objective measurements against established engineering and medical device standards (e.g., ISO, IEC).

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

Not applicable. No human adjudication is mentioned or required for these types of engineering and safety tests.

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. This is not an AI/ML device, nor is it a diagnostic imaging device that would typically undergo an MRMC study.

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

Not applicable. This is a passive accessory device, not an algorithm.

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

The "ground truth" here is compliance with recognized international and national standards for medical devices, specifically for electrical safety, biocompatibility, and intended performance of cutaneous electrodes. This is established through objective physical and electrical measurements, and laboratory biological tests, rather than clinical outcomes or expert consensus on medical findings.

8. The sample size for the training set:

Not applicable. This device does not involve a training set as it is not an AI/ML device.

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

Not applicable.
