AI/ML Overview

The provided text describes the EmFace Device and its submission for FDA 510(k) clearance, asserting its substantial equivalence to a predicate device (InMode PLUS System). The text focuses on safety and performance, rather than specific diagnostic accuracy or classification of medical conditions, which would typically involve detailed acceptance criteria for an AI-powered diagnostic device.

Therefore, many of the requested categories for AI device evaluation are not directly applicable or explicitly stated in the provided documentation, as the device is an electrosurgical cutting and coagulation device.

Here's an attempt to extract relevant information and note where the requested information is not available or applicable based on the provided text:

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

The document does not explicitly define acceptance criteria as pass/fail thresholds for specific clinical outcomes or diagnostic accuracy metrics. Instead, the "acceptance" is based on demonstrating safety and comparable performance to a predicate device, primarily through thermal effects.

Acceptance Criteria (Implied from Safety/Performance Studies)	Reported Device Performance (EmFace Device)
Bench Testing (Temperature Build-up):	Similar temperature build-up to predicate device at 30W and 50W RF outputs.
- Similar heat transfer/loss characteristics
- Temperature stability

Pre-Clinical (Animal) Study (Thermal Effect):
- No signs of tissue necrosis	No signs of tissue necrosis in porcine tissue in all power levels.
- Measured temperature on tissue surface ~43ºC	Measured temperature on tissue surface around 43ºC and lower in deeper tissue layers.

Clinical Performance (Human Study - Safety):
- Safe use for intended purpose	Safe use demonstrated for temporary relief of minor muscle aches and pain, temporary relief of muscle spasm, and temporary improvement of local blood circulation.
- No adverse events reported	No adverse events reported.
- Desirable skin thermal profile (around 43ºC)	Skin thermal profile showed a desirable temperature level of around 43ºC.
- Tolerable discomfort levels	Most subjects endured maximal treatment parameters with mild to moderate discomfort.
- Comparable thermal outcomes to predicate device	Treatment methodology contributes to the same thermal outcomes obtained by using the respective predicate device for the same intended use.

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

Test Set Sample Size (Clinical Study): Thirty (30) eligible human subject participants.
Data Provenance (Clinical Study): Prospective, conducted on human subjects (no specific country of origin mentioned, but the manufacturer is InMode MD Ltd. from Israel).

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

This information is not provided in the document. For aesthetic devices like this, "ground truth" related to diagnostic accuracy is not typically established by expert consensus in the same way it would be for an imaging-based AI diagnostic device. The "ground truth" here revolves around safety (e.g., absence of adverse events, temperature readings) and the observation of the device's intended physiological effects, likely performed by the study investigators.

4. Adjudication method for the test set

This information is not provided in the document. Given the nature of the device (electrosurgical for muscle relief, not a diagnostic tool), a formal adjudication process for "truth" in the context of diagnostic agreement (like 2+1 or 3+1) is not typically applicable. Safety observations and temperature measurements would likely be recorded directly by study staff.

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, an MRMC study was not done. This type of study is relevant for diagnostic imaging interpretation where human readers (e.g., radiologists) use AI assistance to improve their performance. This device is not an AI diagnostic tool and does not involve "human readers" in this context.
Effect Size: Not applicable as no such study was performed.

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

The device functions as a standalone electrosurgical device. Its performance is evaluated on its direct physical effects (temperature, tissue response), not as an algorithm making a decision. The clinical study described evaluates the device in its intended operational mode, which is "standalone" in the sense that it directly applies energy without an AI interpretation layer.

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

The "ground truth" for the device's performance relies on several objective and observational measures:

Bench Testing: Direct physical measurements (temperature build-up at different power levels).
Pre-Clinical (Animal) Study: Histopathological examination (tissue vitality, absence of necrosis) and direct temperature profiling.
Clinical Study: Direct thermal measurements on human skin, skin observation for adverse events, and subject reports of discomfort (absence of adverse events and maintenance of target temperature profiles being the positive "ground truth").

8. The sample size for the training set

This information is not applicable/not provided as the EmFace Device is an electrosurgical device, not an AI/machine learning model that requires a training set. The device is hardware-based with software controls; it learns nothing from data.

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

This information is not applicable as there is no training set for an AI/machine learning model.

Biocompatibility:

The EmFace Device components that come in direct contact with the human body are the device applicator unit's plastic housing and RF electrodes and the applicator adjustable belt set. All of the materials used for the manufacturing of these device components are biocompatible.

Non-Clinical (Bench) Performance Data:

In order to evaluate the similarities of the subject and predicate applicator electrodes in terms of heat transfer/heat loss and temperature stability, the company had performed temperature build up test.

{6}------------------------------------------------

The results of these tests, measured at two different RF outputs levels (30W and 50W), showed similar temperature build up. This is mainly due to the fact that both the subject and predicate devices deliver the same RF output power and that their electrodes geometry is identical.

Pre-Clinical (Animal) Performance Data:

The EmFace Device with the Cheek and Chin Applicators was evaluated for its thermal effect in an ex-vivo animal study model. The device safety assessment included tissue vitality evaluation and tissue temperature profiling following a single treatment with either the Cheek or Chin Applicators on porcine tissue. The device applicators were operated in different power outputs for the recommended treatment time. The study results revealed no signs of tissue necrosis in all of the animal tissues treated with the device applicators in all power levels. The measured temperature on tissue surface was around 43ºC and lower in deeper tissue layers following the treatment with the device applicators in all power levels.

Clinical Performance Data:

The EmFace Device with the Cheek and Chin Applicators was further evaluated for its safe performance on thirty eligible human subject participants with different age, gender, and Fitzpatrick skin types.

The study consisted of a single treatment followed by immediate photography and thermal measurements of the treatment area per each applicator treatment. Skin observation was done immediately and 24h post treatment and was extended up to 48h following treatment to assess possible skin transient response. Subjects were treated on their Cheek facial area with the Cheek Applicator and on their Chin facial area with the Chin Applicator. Treatment included a maximal number of applicator units according to area size, utilizing maximal RF power setting (50W), at the highest cut-off temperature value (43ºC).

The study results clearly show the safe use of the EmFace Device with the Cheek and the Chin Applicators for its intended use while utilized in accordance with the device operator manual treatment instructions. The temperature measurements along with the skin observation for adverse events show that the treatment methodology of both EmFace Device Applicators contribute for the same thermal outcomes obtained by using the respective predicate device for the same intended use. The safe use of the EmFace Device Applicators was shown on all potential end-users with different age, gender and skin type. No adverse events were reported in this study and the skin thermal profile showed a desirable temperature level of around 43ºC. Most of the subjects endured the maximal

{9}------------------------------------------------

The device classification and indications for use of the EmFace Device are substantially equivalent to the device classification and indications for use of the predicate device.

The technological characteristics of the subject device is based on that of the predicate device. The EmFace Device comprises similar platform components; AC/DC power supply unit, RF generators, controller and user interface including an LCD touch screen. The EmFace Device design mainly differentiate from its predicate device with the option to perform a hands-free treatment using multiple applicator units, operated sequentially. The device is provided with three units of the Chin applicator and eight units of the Cheek (4 on each cheek side) applicator. With this design change, the applicators' performance specifications, mainly the RF frequency and electrical power, pulse duration, were left unchanged, but the treatment technique has been modified to provide the same performance outcomes to the target area; warm heating of the skin and subdermal layers by non-thermal RF energy. In order to support this design change, a few platform modifications were made including an additional RF generator and an increased input current of 4A to support the multi applicator unit's functionality and an upgrade in system software and hardware components to support the aforementioned change. The EmFace Device is backed up with the safety features as applied in the predicate device systems. The EmFace Device was tested and complies with the safety and EMC standards as requested for RF technology-based devices. The EmFace Device with the Cheek and Chin Applicators was further evaluated for its safe performance in bench temperature build up tests, ex-vivo Animal study and in a human clinical study. The results of these studies demonstrated that the EmFace Device is safe for use as intended and that the minor design differences between the subject and predicate device, mainly in the treatment methodology, do not raise any new safety or effectiveness concerns.

Consequently, it can be concluded that the EmFace Device is substantially equivalent to the InMode PLUS System predicate device, FDA cleared under 510(k) file no. K153568.

Conclusions:

Based on the comparison to the predicate device and on the bench, non-clinical and clinical performance testing results demonstrating that the EmFace Device is as safe and effective as the predicate device, it can be concluded that the EmFace Device is substantially equivalent to the predicate device and therefore, may be legally marketed in the USA.
