The ACTIVO is based on the Nd:YAG(1064nm) and KTP Nd: YAG(532nm) laser technology. It is indicated for the incision, ablation, vaporization of soft tissues for general dermatology. Three basic elements of operations are as follows: 1) A Nd:YAG crystal is used as a gain medium which produces a laser beam. 2) A resonator then amplifies the beam. 3) A lamp that contains Xe gas is used, as a pumping light source. The lamp requires a high-pressure power source device for operation. When the electric energy generated from the high-pressure power source is induced into the electrode of the lamp, it converts into light energy(1064nm). This converted light energy pumps the Nd: YAG crystal - a gain medium - and the light exhausted from the crystal is amplified into a specific wavelength light(532nm). As it passes between the resonant gases, laser beam radiates to an output unit. The regulation of laser output and repetition rate can be set by the user via GUI (Graphic User Interface) and controlled by microprocessor, which interfaces with the power supply.

This FDA 510(k) summary is for the ACTIVO laser surgical instrument. It relies on non-clinical testing for substantial equivalence, as no clinical testing was performed or required. Therefore, the device does not have acceptance criteria defined by an effectiveness study that proves its performance against clinical endpoints. Instead, its acceptance criteria are based on meeting design specifications and demonstrating substantial equivalence to a predicate device through non-clinical performance and safety standards.

Here's a breakdown of the requested information based on the provided document:

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

Since this filing is based on substantial equivalence through non-clinical testing, the "acceptance criteria" are the standards and design specifications met by the device, and the "reported device performance" is that it successfully met these standards.

2. Sample size used for the test set and the data provenance (e.g., country of origin of the data, retrospective or prospective)

• Sample Size for Test Set: Not applicable. No clinical test set involving human or animal subjects was used as the submission relies solely on non-clinical testing and comparison to a predicate device.
• Data Provenance: Not applicable for clinical data. For non-clinical testing, the tests were conducted at facilities presumably in the country of manufacture or a certified testing laboratory, but this specific detail is not provided. The device manufacturer is DAEJU MEDITECH ENGINEERING CO., LTD. in Seoul, Republic of Korea.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g., radiologist with 10 years of experience)

• Not applicable. There was no clinical test set requiring expert ground truth establishment. The document refers to compliance with international standards and internal verification for non-clinical aspects.

4. Adjudication method (e.g., 2+1, 3+1, none) for the test set

• Not applicable. No clinical test set requiring adjudication was used.

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. No MRMC study was conducted. This device is a laser surgical instrument, not an AI-assisted diagnostic or treatment planning system that would involve human readers.

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

• Not applicable. This is a physical medical device (laser surgical instrument), not a standalone algorithm.

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

• Not applicable for clinical ground truth. For non-clinical testing, the "ground truth" equivalent would be the established specifications and parameter tolerances of the device, and the established limits and requirements of the referenced international standards (e.g., IEC 60601-1, ISO 10993).

8. The sample size for the training set

• Not applicable. This device is a physical laser instrument, not an AI/ML-based device that requires a training set.

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

• Not applicable. No training set was used.
