The Glide™ device is an over the counter device intended for the removal of unwanted hair. The Glide™ device is also intended for permanent reduction in hair regrowth, defined as the longterm, stable reduction in the number of hairs regrowing when measured at 6, 9, and 12 months after the completion of a treatment regime.

Device Description

The Glide device is a pulsed light hair removal device. Light-based hair removal is based on the theory of selective photothermolysis in which optical energy is used to disable hair growth. The Glide device is composed of a hand held applicator. The device contains 6 LEDs indicated 5 different energy levels and other device functions. The spot size in the Glide device is 2.7cm . The device contains a lamp, a temperature sensor, a skin proximity sensor and a skin color sensor to detect appropriate skin tones. The skin sensor scans darker skin tones and will not pulse if the skin tone is not suitable for treatment.

AI/ML Overview

This document describes the premarket notification for the "Glide Device," a pulsed light hair removal device. The submission primarily relies on substantial equivalence to a previously cleared device rather than on extensive new clinical performance data. Therefore, many of the typical acceptance criteria and study details for AI/software-based devices are not applicable.

Here's an analysis of the provided information based on your requested points:

1. Table of Acceptance Criteria and Reported Device Performance

The submission does not explicitly state quantitative acceptance criteria for clinical performance (e.g., hair reduction percentage). Instead, it focuses on demonstrating safety and functional equivalence to a predicate device. The primary "acceptance criteria" are compliance with voluntary recognized standards and successful usability testing.

Acceptance Criteria Category	Specific Criteria (if stated)	Reported Device Performance
Safety - Electrical/Mechanical	IEC 60601-1 (General Safety)	Complies with standard
	IEC 60601-1-2 (EMC)	Complies with standard
	EN 62471 (Photobiological Safety)	Complies with standard
	EN 60601-2-57 (Non-laser light source)	Complies with standard
Software Validation	IEC 60601-1-4; FDA Guidance	Software Validation conducted
Usability	Safe and effective device use by potential end users under actual use conditions	100% of 20 enrolled subjects completed all tasks successfully, indicating safe and effective use.
Indications for Use (Substantial Equivalence)	Intent to achieve permanent reduction in hair regrowth (6, 9, 12 months post-treatment) equivalent to predicate.	No new clinical data presented. Equivalence based on similar technology and performance specifications to predicate device (Silk'n Flash N Go).

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

Usability Study: The test set for the usability study consisted of 20 potential device end users.
Data Provenance: The study was likely conducted prospectively in a simulated home use environment for the usability assessment. The country of origin is not specified but the applicant is based in Israel.
Clinical Performance: No specific clinical test set data from the Glide device is provided or used for evaluation as the submission relies on substantial equivalence.

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

Usability Study: The document does not mention the use of "experts" to establish a ground truth for the usability study in the traditional sense of clinical experts (e.g., radiologists). The "ground truth" for usability was likely defined by successful completion of tasks by the 20 end users and their subjective feedback through questionnaires.
Clinical Performance: For clinical performance (hair reduction), no new clinical studies with expert-established ground truth were performed for the Glide device, as the submission relies on substantial equivalence.

4. Adjudication Method for the Test Set

Usability Study: No explicit adjudication method (like "2+1" or "3+1") is described. The assessment of "successful completion of tasks" for the 20 users appears to have been direct observation and possibly self-reporting via questionnaires.
Clinical Performance: Not applicable, as no new clinical test set data from the Glide device was presented.

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. This device is a pulsed light hair removal device, not an AI or software-assisted diagnostic or interpretative tool. Therefore, MRMC studies involving human readers and AI assistance are not relevant to this submission.

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

Not Applicable. This is a hardware device. While it contains software for controlling its functions (like skin color sensing), it's not an "algorithm-only" or AI diagnostic device in the context typically discussed for standalone performance evaluations. The device's safety features (skin sensor, temperature sensor) operate automatically.

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

Usability Study: The "ground truth" was essentially the observed success of users completing device operation tasks and their qualitative feedback on usability. This is not a clinical ground truth like pathology or outcomes data.
Clinical Performance: For the intended use of permanent hair reduction, the ground truth would typically be hair count reduction measured at specific time points. However, for the Glide device submission, this outcome data was not specifically collected for this device during the approval process. The claim of achieving permanent hair reduction relies on the substantial equivalence to the predicate device, which presumably demonstrated this through its own studies.

8. The Sample Size for the Training Set

Not Applicable. This submission does not describe an AI/ML algorithm that requires a "training set" in the conventional sense. The device's software is related to control functions and safety features, which are typically validated through software testing and hardware integration rather than machine learning training.

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

Not Applicable. As there is no described AI/ML training set, the establishment of ground truth for such a set is not relevant.

In Summary:

The K131870 submission for the Glide Device is a 510(k) premarket notification primarily based on substantial equivalence to an existing predicate device (Silk'n Flash N Go). Therefore, it largely emphasizes demonstrating that the new device shares similar technological characteristics, performance specifications, and safety features with the predicate, and complies with relevant safety standards.

A usability study was conducted with 20 end users to ensure safe and effective operation given minor design changes, and this served as a key performance data point for the new design. However, there were no new clinical trials with specific acceptance criteria for hair reduction performed for this particular submission, nor are there any AI/ML components requiring training sets or MRMC studies.

Twenty (20) potential device end users were enrolled in the Usability Study. The Glide device, in its original packaging, along with the user manual and QuickStart guide was provided to the patient in a simulated home use environment. The patient labeling was in the format intended for distribution. All subjects were provided with a pre-test and post-test questionnaire and a list of tasks to complete, including applying and operating the device.

All of the 20 enrolled subjects (100%) completed all tasks successfully. The Glide device, in its

{2}------------------------------------------------

original packaging, along with the user manual and QuickStart guide, can be used safely and effectively by potential end users, under actual use conditions.

Clinical Performance Data:

Not applicable.

Substantial Equivalence:

The indications for use and technological characteristics of the Glide device are substantially equivalent to the indications for use and technological characteristics of the Silk'n Flash N Go device.

The design and components in the Glide device, including the hand piece applicator (with 12V regulator, lamp, microcontroller, fan, temperature sensor, skin proximity sensor, indicator LEDs and operational button/s} are similar to the design and components found in the predicate Silk'n Flash N Go device, although in the predicate device these components are found in either the hand piece applicator or the base unit and in the Glide device all components are in the hand piece applicator. The performance specifications (including light energy power, wavelength and pulse duration) in all the devices are identical. The safety features found in all the devices are the same, including the system self-check, temperature sensor, skin color sensor, skin proximity sensor, etc. These safety features in the Glide device are substantially equivalent to the safety features found in the predicate device. Any minor differences in the technological characteristics do not raise new safety or effectiveness concerns. Furthermore, the new Glide device underwent performance testing, including software validation testing and electrical and mechanical safety testing according to IEC 60601-1 and electromagnetic compatibility testing according to IEC 60601-1-2 (provided in Section 12). Usability testing was also conducted due to the design changes in the operational buttons and indicator LEDs in the Glide device and the results are presented in Section 12, as well. These performance tests demonstrate that the minor differences in the device software and design meet the system requirements and do not raise new safety or effectiveness concerns.

Consequently, it can be concluded that the Glide device is substantially equivalent to the predicate Silk'n Flash N Go device, cleared under 510(k) K103184 and therefore, may be legally marketed in the USA.

Conclusions:

Based on the performance testing and comparison to the predicate device, the Glide device is substantially equivalent to the Silk'n Flash N Go predicate device.
