Device Description

DUET-V (Model: ESK-3261DV) is a High Frequency Therapy Device system using 4 MHz high frequency electrical current. Single-use, disposable Treatment Tips attach to the handpiece that comes into contact with the patient during treatment procedures. Treatment tips are classified as direct skin contact devices of limited duration (<24 hours). The RF handpiece has 2 types of fractional tips and 3 types of thermal tips. The tips are disposable and are provided in a non-sterile state. Mono-polar electrodes TRF TIP-S, TRF TIP-R, and TRF TIP-E are used with a grounding pad. Bipolar electrodes FRF TIP-64 and FRF TIP-100, unlike mono-polar electrodes, do not have a ground pad and current flows between electrodes on the contact surface. The tip has three modes: Shot mode, Auto Shot mode, and Continuous mode - Shot Mode this mode delivers the output value set by the user once - Auto Shot Mode In this mode, the set output value delivered continuously according . to the interval time set by the user. (only TRF-TIP-S) - Continuous Mode - this mode continuously delivers RF current until stopped by the user.

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

The document does not specify a "test set" in the context of a clinical performance evaluation (e.g., patient images or data). The performance testing described is focused on bench testing, electrical safety, biocompatibility, and software validation. Therefore, there is no information provided on sample size or data provenance for a clinical test set.

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

As there is no clinical test set described, there is no information on the number or qualifications of experts for establishing ground truth. The evaluations are technical and regulatory compliance tests.

4. Adjudication Method for the Test Set

Again, given the nature of the evaluation (technical and regulatory compliance), there is no mention of an adjudication method for a clinical test set.

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

There is no mention of an MRMC comparative effectiveness study, nor is there any AI component described that would require such a study. The device is an electrosurgical unit, not an AI-powered diagnostic tool.

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

There is no mention of a standalone algorithm performance study, as the device described is an electrosurgical unit and not an AI algorithm.

7. The Type of Ground Truth Used (expert consensus, pathology, outcomes data, etc.)

For the described technical and safety performance tests, the "ground truth" is established by engineering standards, regulatory guidelines (e.g., ISO, IEC, FDA guidances), and pre-defined acceptable ranges for physical and electrical parameters. For example, for "Accuracy of Output control setting," the ground truth is the ±20% acceptance criteria of the standard value. The "Thermal Effects on Tissue" and "Temperature Monitoring" tests are performed against the requirements of specific FDA guidances.

8. The Sample Size for the Training Set

The concept of a "training set" is relevant for machine learning algorithms. Since this device is an electrosurgical unit and not an AI-driven system, there is no training set described.

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

As there is no training set, there is no information on how its "ground truth" was established.
