Type of Use: Prescription Use

The Discovery Pico Family includes medical laser devices for dermatology and aesthetic medicine used by healthcare professionals (dermatologists) in professional healthcare environments. The family comprises Discovery Pico, Discovery Pico Plus, and Discovery Pico Derm models, which differ based on installed laser sources and the presence of a Twain connector.

The device is equipped with a graphical user interface (GUI) displayed on a screen for user interaction, allowing for laser parameter settings. It can be used with Twain IPL and Twain 2940 devices (Twain 2940 is separately FDA cleared K173002).

The laser beam is delivered via an articulated arm with a handpiece and activated by a footswitch. Four types of handpieces are available:

• Round (diameter): 2 to 12 mm
• Square (side): 2, 3, 4, 5, 7 mm
• Microbeam/fractional handpieces: 8, 9 mm (9 mm microbeam handpiece is also called "High Coverage")
• Rosso handpiece (separately FDA cleared: K211228)

The device incorporates four main sections:

• Power electronics: Manages power supply to all device components.
• Control electronics: Primarily consists of a microcontroller board housing the device's main firmware (FW).
• Cooling system: Cools the laser source pumping chamber and, for Twain IPL, the IPL flashlamp.
• Optical bench.

Twain IPL is an optional accessory handpiece for intense pulsed light (IPL), intended for hair reduction and treatment of various skin lesions. Twain IPL can be cooled or uncooled and supports fixed or changeable guides with wavelength ranges of 650-1200 nm, 625-1200 nm, 590-1200 nm, 570-1200 nm, 550-1200 nm, and 400-1200 nm. Each guide is available in two sizes: small (25x13 mm²) and large (48x13 mm²).

In picosecond (PS) mode, the device offers "VarioPulse" technology, allowing the user to select three pulse levels corresponding to different pulse durations:

• Short (S): 450 ps (1064 nm), 370 ps (532 nm)
• Medium (M): 600 ps (1064 nm), 500 ps (532 nm)
• Long (L): 800 ps (1064 nm), 600 ps (532 nm)

The provided text is an FDA 510(k) clearance letter for the Discovery Pico Family of laser devices. While it outlines the device's indications for use, its technical specifications, and the non-clinical tests performed to demonstrate safety and effectiveness, it explicitly states "Clinical testing: N/A."

This means that the submission for this particular device did not include a clinical study (such as an MRMC study or a standalone algorithm performance study) to prove specific performance criteria against a ground truth in a human-in-the-loop or algorithm-only setting. The clearance relies on non-clinical bench testing and comparison to predicate devices, demonstrating substantial equivalence rather than a direct clinical performance study against quantified acceptance criteria for a specific AI-driven task.

Therefore, many of the requested details about acceptance criteria, study design, sample sizes, expert involvement, and ground truth establishment cannot be found in this document because a clinical study with those elements was not conducted or presented for this 510(k) submission.

Below is a table summarizing the information that is available from the document and indicating where the requested information is "N/A" (Not Applicable) or "Not Provided" due to the nature of this 510(k) submission (bench testing and predicate comparison, not a clinical trial proving AI performance).

Acceptance Criteria and Device Performance (Based on available information)

Study Details (Based on available information)

In summary: The FDA 510(k) clearance for the Discovery Pico Family is based on demonstrating substantial equivalence to previously cleared predicate devices through non-clinical bench testing, adherence to recognized standards for safety and performance (electrical, software, biocompatibility, reprocessing), and comparison of technical specifications. It does not involve a clinical study to evaluate AI performance against specific clinical acceptance criteria or a ground truth derived from expert consensus or outcomes data. Therefore, the detailed questions related to such clinical studies are not applicable to this specific clearance document.

All the models belonging to the Discovery Pico Family have the same components and the same controlling software. The only difference between different models is the optical bench that depends on the sources installed.

The Discovery Pico Family is controlled via a touch screen display housed in the front of the device.

Emission is triggered by means of a footswitch.

The provided text is a 510(k) summary for the Discovery Pico Family laser device, submitted to the FDA. It details a modification to an already cleared device, primarily the addition of microbeam handpieces. As such, the acceptance criteria and performance data presented are focused on engineering and safety performance, rather than clinical efficacy or diagnostic accuracy as would be the case for an AI/ML-driven diagnostic device.

Therefore, many of the requested fields related to clinical studies, human reader performance, ground truth establishment for clinical data, and training set information are not applicable to this type of device submission.

Here's the information derived from the provided text:

1. Table of Acceptance Criteria and Reported Device Performance:

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

• Not applicable / Not specified. The performance data described are related to engineering and safety bench tests (e.g., electrical safety, EMC, output measurements on microbeam handpieces) and software validation. These do not typically involve patient-specific test sets in the same way clinical diagnostic studies do. The phrase "Bench testing measurements were done" implies testing on physical units/components, not patient data.

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

• Not applicable. For engineering and safety tests, the "ground truth" is typically established by objective measurements against predefined specifications and recognized standards, not by expert human interpretation of clinical data.

4. Adjudication method for the test set:

• Not applicable. Adjudication methods like 2+1 or 3+1 are used for resolving disagreements among human readers in a clinical study. This device's testing involves objective measurements against engineering standards.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, what was the effect size of how much human readers improve with AI vs without AI assistance:

• No. This is not an AI-assisted diagnostic device, but a physical laser device for surgical and aesthetic applications. Therefore, an MRMC study and AI assistance effect size are not relevant.

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

• No. This is a physical laser device, not an algorithm. The software verification and validation are for controlling the device, not for making independent diagnostic or therapeutic decisions.

7. The type of ground truth used:

• For electrical safety, EMC, and laser safety: Compliance with recognized consensus standards (e.g., IEC 60601 series, IEC 60825-1).
• For microbeam handpiece output: Physical bench measurements to confirm output against design specifications.
• For software: Verification and validation against software requirements as per FDA guidance.
• For biocompatibility: Reference to the predicate device.

8. The sample size for the training set:

• Not applicable. As this is not an AI/ML device, there is no "training set" in the context of machine learning.

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

• Not applicable. No training set was used for an AI/ML algorithm.
