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.

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.

Diode laser is a kind of laser with semiconductor as working material. It consists of working material, cavity resonator and power source. The diode laser for this unit is GaAlAs diode bar, and the wavelength is 1940nm for GBOX-6H, VELAS II -6H; 1470nm for GBOX-10D, GBOX-12D, GBOX-15D, VELAS II -15D; 980nm or 1470nm for VELAS Pro-30B15D. It features impact structure, high efficiency and long lifetime. Generally, the beam shall be emitted as the big beam divergence of the laser from the diode. With the unique fiber-coupling technology, the laser beam can be coupled efficiently into the fiber.  MCU (Micro Controller Unit) is the control center of system. MCU controls the drive board and temperature system by changing operating current. The operating power supply is the power source of the whole system. It supplies power for MCU, diode laser module by DC-DC conversion module and temp system by temp-control circuit. MCU controls the drive current of diode laser module by adjusting the DC-DC module and current-control circuit. The MCU has three external input sources: footswitch, remote interlock connector and information input {9} from the touch units, it has one external output unit: display terminal. The diode laser module provides laser power output by fiber with optical fiber coupling system. V.

There are no differences between the subject and predicate devices. 16 / 17 {21} 17 / 17 # VII. PERFORMANCE DATA The following performance data were provided in support of the substantial equivalence determination. ## Electrical safety and electromagnetic compatibility (EMC) Electrical safety and EMC testing were conducted on the Medical Diode Laser Systems. - Verify the conformity of the proposed devices with the requirements of 2005(R)2012 IEC60601-1 : (Medical electrical equipment Part 1: General requirements for basic safety and essential performance). - Verify the conformity of the proposed devices with the requirements of 2020-09 IEC60601-1-2 : (Medical electrical equipment Part 1-2: General requirements for basic safety and essential performance Collateral Standard: Electromagnetic compatibility). - Verify the conformity of the proposed devices to 2007-03 IEC 60825-1 (Safety of laser products - Part 1: Equipment classification and requirements). - Verify the performance of the proposed devices according to 2012-10 IEC 60601-2-22: (Medical electrical equipment Part 2: Particular Requirements for basic safety and essential performance of surgical, cosmetic, therapeutic, and diagnostic laser equipment). - Verify the conformity of the proposed devices with the requirements of 2020-07 IEC 60601-1-6: (Medical electrical equipment - Part 1-6: General requirements for basic safety and essential performance Collateral standard: Usability) ## Software Verification and Validation Testing Software verification and validation testing were conducted and documentation was provided as recommended by FDA's Guidance for Industry and FDA Staff, "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices." The software for this device was considered as a "moderate" level of concern. ## Mechanical and acoustic testing It is not applicable. ## Animal Study It is not applicable. ## Clinical Studies It is not applicable. # VIII. CONCLUSIONS The Medical Diode Laser Systems is substantially equivalent to its predicate devices. The non-clinical testing demonstrates that the device is as safe, as effective and performs as well as the legally marketed devices.
