The enlighten III laser system is intended for use in surgical and aesthetic applications in the medical specialties of dermatology and general and plastic surgery.

1064 nm:
The 1064 nm wavelength of the enlighten III laser system is indicated for:

  • treatment of benign pigmented lesions on patients with all skin types (Fitzpatrick I-VI)
  • tattoo removal for dark colored tattoo inks and for multicolored tattoos containing dark colored tattoo inks on patients with all skin types (Fitzpatrick I-VI)

532 nm:
The 532 nm wavelength of the enlighten III laser system is indicated for:

  • treatment of benign pigmented lesions on patients with Fitzpatrick skin types I-III
  • tattoo removal for lighter colored tattoo inks, including red and yellow inks, on patients with Fitzpatrick skin types I-III

670 nm:
The 670 nm wavelength of the enlighten III laser system is indicated for treatment of benign pigments with Fitzpatrick skin types I-III.

Device Description

The modified Cutera enlighten III laser system is a multi-wavelength, pulsed laser system. A key feature of the device is its ability to produce multiple laser wavelengths and pulse widths (1064 and 532 nm: 750 ps and 2 ns; 670 nm: 660 ps and 2 ns).

The laser, power supplies, and control electronics are housed inside a console equipped with a touchscreen control panel. The laser treatment parameters are selected using the control panel. Laser emission is activated by depressing a footswitch. An articulated arm with rotational mirror knuckles delivers the laser beam from a laser head inside the console to a handpiece. The handpiece is equipped with an optical zoom assembly that determines the spot size of the laser beam on the treatment surface. The beam of a low-power diode laser is also transmitted through the arm to provide an aiming beam.

AI/ML Overview

This document is an FDA 510(k) premarket notification for a modification to the Cutera enlighten III Laser System. It focuses on demonstrating substantial equivalence to a previously cleared device. Therefore, it does not contain the kind of detailed study data (like sample sizes, expert qualifications, or comparative effectiveness with human readers) that would be present in a clinical trial report for a new device.

Here's an analysis of what is and isn't provided based on your request:

1. Table of Acceptance Criteria and Reported Device Performance

The document does not explicitly state "acceptance criteria" for clinical performance. Instead, it details modifications to the device's operational parameters and then asserts that these modifications do not introduce new risks or change the intended use, implying that the device, with these modifications, still meets the safety and effectiveness profile of its predicate.

However, the key performance data discussed relates to the device's technical specifications and compliance with safety standards.

Acceptance Criteria (Implied / Stated Compliance)Reported Device Performance (with modifications)
Safety and Electrical Standards ComplianceComplies with: - IEC 60601-1 (Edition 3.1, 2012) - IEC 60601-1-6 (Edition 3.1, 2013) - IEC 62366 (Edition 1.1, 2014) - IEC 60601-2-22 (Edition 3.1, 2012) - IEC 60825-1 (Edition 2.0, 2007) - AAMI/ANSI ES60601-1:2005+A2 (R2012)+A1 - IEC 60601-1-2 (Edition 3, 2007)
Maximum Delivered Energy1064 nm: Increased from 600 mJ to 800 mJ (maintaining 10 J/cm² max fluence) 532 nm: Increased from 300 mJ to 400 mJ (maintaining 2.5 J/cm² max fluence)
Maximum Treatment Fluence1064 nm: Maintained at 10 J/cm² 532 nm: Maintained at 2.5 J/cm²
Spot SizesAdded 9 mm and 10 mm incremental spot sizes for 1064 nm and 532 nm wavelengths.
Pulse DurationAdded 2 ns pulse duration for the 670 nm wavelength.
No New Risks IntroducedAffirmed based on unchanged maximum treatment fluence and no changes to intended use or indications for use.
Equivalence in Intended Use/IndicationsIdentical to predicate device.
Equivalence in Technical SpecificationsSimilar or within range of predicate and reference devices in spot sizes, wavelengths, pulse widths, laser types, and repetition rates.
Equivalence in Operating PerformanceSimilar to predicate and reference devices.
Equivalence in General DesignSimilar to predicate and reference devices.

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

The document refers to a "Performance Data: enlighten III Software Verification and Validation Testing Report (V0140 rA1)". This report likely contains the details of the test set and data provenance for the software modifications. However, the FDA letter does not provide any specific sample sizes or data provenance (e.g., country of origin, retrospective/prospective) for clinical or performance data related to the device's efficacy in treating patients.

The "testing" mentioned primarily concerns software verification and validation and compliance with electrical and safety standards, not a clinical study on human subjects with a "test set" in the context of diagnostic accuracy.

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. As this is a 510(k) for a laser system modification, the "ground truth" would likely refer to the physical output parameters of the laser, verified by engineering and metrology, rather than expert clinical consensus on patient outcomes, which is typical for AI diagnostic devices.

4. Adjudication method for the test set

This information is not provided. Given the nature of the device (a laser system for treatment), "adjudication method" in the context of reconciling expert opinions (as described by "2+1, 3+1") is not relevant here. The "testing" pertains to engineering standards and device performance specifications.

5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done

No, an MRMC comparative effectiveness study was not done or described in this document. This type of study is relevant for evaluating the impact of AI algorithms on human reader performance, typically in diagnostic imaging, which is not the function of this laser system.

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

This concept is not applicable to this device. The Cutera enlighten III is a physical laser system, not a diagnostic algorithm. The "algorithm" here refers to the control software that dictates the laser's operational parameters, and its "performance" is judged by its ability to control the hardware within specified tolerances and safety limits.

7. The type of ground truth used

The implicit "ground truth" for this device's performance is its technical specifications and adherence to international safety and electrical standards (e.g., IEC 60601-1, IEC 60825-1, etc.), as well as the accurate output of laser parameters (energy, fluence, spot size, pulse duration). This is established through engineering measurements and metrology, not pathology, outcomes data, or expert clinical consensus on patient diagnosis.

8. The sample size for the training set

This information is not applicable and therefore not provided. The device's "software modification" does not involve machine learning or AI models that require a "training set" in the typical sense of classifying data or predicting outcomes. The software is a set of control logic and algorithms to operate the laser system.

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

This information is not applicable for the same reasons as #8.

  • Device Modifications The purpose of this submission is to modify the control software of the previously cleared Cutera enlighten III laser system to enable access to the full parameter range of the enlighten III laser system. The modified and unmodified systems are identical in mechanical, electrical, and thermal design. The modified software will:
    • . Change the maximum delivered energy from 600 mJ to 800 mJ for the 1064 nm wavelength and from 300 mJ to 400 mJ for the 532 nm wavelength, while maintaining the previously cleared maximum treatment fluences of 10 J/cm² and 2.5 J/cm² for the 1064 nm and 532 nm wavelengths, respectively.
    • Add 9 and 10 mm incremental spot sizes for the 1064 and 532 ● nm wavelengths.
    • . Add 2 ns pulse duration for the 670 nm wavelength.

Cutera has determined that no new risks have been introduced due to the above changes, as the maximum treatment fluence for all wavelengths remains unchanged and there are no changes to the intended use or indications for use.

Summarv of Technological Characteristics: The modified Cutera enlighten III laser system has the same intended use and indications for use and the same fundamental scientific technology as the previously cleared unmodified Cutera enlighten III laser system (K160488), Quanta System Q-Plus T (K073549), and Cynosure RevLite (K133254), The device design and components are also very similar to these devices. For each of these devices:

  • the user interface is located at the front/top of the console;
  • . the treatment handpiece is attached to an articulating arm that is connected to the main system console;
  • . the laser output at each wavelength is generated within the laser chassis and delivered to the skin through the handpiece attached to the articulated arm; and
  • the handpiece allows the spot size on the skin to be . adjusted according to device specifications.

Each system consists of an articulating arm and attached handpiece, as well as an electrically powered system console that produces the laser energy and houses the software and user interface.

The modified Cutera enlighten III laser system provides similar key design aspects, including the same or similar spot sizes, laser wavelengths, pulse widths, and laser types as its predicate and reference devices. The repetition rate of the enlighten III laser system is the same as or within the repetition rate range of the

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

predicate device. Further, each of the devices presents a range of spot sizes to allow the user to choose the most appropriate spot size for each patient. Therefore, the minor differences do not raise any new safety or effectiveness questions, because the enlighten III parameters are the same as or within the range of the predicate and reference devices.

  • Conclusion: The enlighten III laser system is substantially equivalent to the predicate device in terms of indications for use, technical specifications, operating performance features, and general design.
