Dated: March 26, 2025
Received: April 1, 2025
Dear Dandan Wang:
We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device" (https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download).
Your device is also subject to, among other requirements, the Quality System (QS) regulation (21 CFR Part 820), which includes, but is not limited to, 21 CFR 820.30, Design controls; 21 CFR 820.90, Nonconforming product; and 21 CFR 820.100, Corrective and preventive action. Please note that regardless of whether a change requires premarket review, the QS regulation requires device manufacturers to review and approve changes to device design and production (21 CFR 820.30 and 21 CFR 820.70) and document changes and approvals in the device master record (21 CFR 820.181).
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting (reporting of medical device-related adverse events) (21 CFR Part 803) for devices or postmarketing safety reporting (21 CFR Part 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reporting-combination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR Part 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR Parts 1000-1050.
All medical devices, including Class I and unclassified devices and combination product device constituent parts are required to be in compliance with the final Unique Device Identification System rule ("UDI Rule"). The UDI Rule requires, among other things, that a device bear a unique device identifier (UDI) on its label and package (21 CFR 801.20(a)) unless an exception or alternative applies (21 CFR 801.20(b)) and that the dates on the device label be formatted in accordance with 21 CFR 801.18. The UDI Rule (21 CFR 830.300(a) and 830.320(b)) also requires that certain information be submitted to the Global Unique Device Identification Database (GUDID) (21 CFR Part 830 Subpart E). For additional information on these requirements, please see the UDI System webpage at https://www.fda.gov/medical-devices/device-advice-comprehensive-regulatory-assistance/unique-device-identification-system-udi-system.
Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to https://www.fda.gov/medical-devices/medical-device-safety/medical-device-reporting-mdr-how-report-medical-device-problems.

Analysis 1: Working Mode
The differences between working modes are merely in terms of descriptions. The parameter values and intended uses are consistent. The correspondence of the two modes is as follows.
| ITEM | Proposed Device | Predicate Device1 K191518 | Note |
|---|---|---|---|
| Work Mode | Surgical Mode（Continuous, Repetitive Pulses） | Surgical mode (Single Pulse, Continuous, Muti-Pulse) | We have two modes, Continuous and Repetitive Pulses, which are within the scope of the Predicate device. Repetitive Pulses and Multi - Pulse are just different in wording |
Analysis 2: Pulse Width
Classical mode: Matches the Predicate Device (K191518: Classical mode, 0.1–10 ms) – the slight lower bound difference (0.1 ms vs. 1 ms) is clinically insignificant, as both ranges fall within the safe and effective window for skin resurfacing, avoiding excessive thermal damage or ineffective tissue ablation.
Normal mode: Aligns with the Predicate Device (K191518: Surgical mode, 0.5–1000 ms) – the Proposed Device's 1–500 ms range is a subset of the Predicate's range, ensuring no higher risk of thermal injury. Reference Device 2 (K162169: 1–1000 ms) has a wider range, but the Proposed Device's range is fully contained within it, guaranteeing equivalent safety and effectiveness. Reference Device 1 (K201109) lists multiple pulse width sub-modes (e.g., Single Pulse: 10–500 ms; U.Pulse: 0.1–0.9 ms), all of which overlap with the Proposed Device's ranges. So this difference will not affect safety and effectiveness of the proposed device.
Conclusion:
CO2 Laser System is substantial equivalent to the predicate device.
12. Clinical Test Conclusion
Page 14
No clinical study is included in this submission.
13. Substantially Equivalent(SE) Conclusion
The CO2Laser Therapy System has the same intended use, similar indications for use, the same technological characteristics, the same energy used, and the same operating principles as its predicates. The non-clinical data and performance testing reports in this submission demonstrate that CO2Laser Therapy System meets the expected performance requirements. Any difference between the subject and predicate device do not raise new issues of safety or effectiveness. Based on above analysis, the CO2Laser System is substantial equivalent to the cited predicate device.
