Uni-Laser 425P™ Diode Laser System and Accessories
This document is a marketing clearance letter from the FDA for the Uni-Laser 425P™ Diode Laser System and Accessories (K991659). It primarily states that the device is substantially equivalent to legally marketed predicate devices.
Crucially, this document does not contain information about:
- Acceptance criteria or reported device performance.
- Any specific study design, sample sizes, data provenance, expert qualifications, or ground truth establishment.
- Comparative effectiveness studies (MRMC) or standalone algorithm performance.
Therefore, I cannot provide the requested table or detailed study information based on the provided text. The document confirms the device's regulatory clearance but does not delve into the technical details of its performance testing.

Dear Dr. Chou:
We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to 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 (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. 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.
· If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations. Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
