Dear Kaitlynn Min:

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).

#### 8. Safety, EMC and Performance data comparison to Predicate [21 CFR 807.92(b)]

DVAS have been successfully compeleted verification and validation testing per GENORAY quality system as well engineering bench testing in support of successfully completed verification and validation testing per GENORAY quality system and this submission.

The system has been tested and is compliant with IEC 60601-1, IEC 60601-1-2, IEC 60601-1-3. IEC 60601-1-6. IEC 60601-2-65. IEC 62366. Also. DVAS complies with all applicable 21 CFR performance standards (21 CFR 1020.30, 21 CFR 1020.31)

And Software was validated according to the FDA Guidance "Guidance for the Content of Premarket Submissions for Software Contained in Medical devices", FDA Guidance "Guidance for the content of premarket submissions for management of cyber security". Results demonstrated that all executed verification tests were passed.

DVAS can be used not only in adults but also In the pediatric population, and therefore the system has reflected pediatric information in the labeling according to the FDA Guidance "Pediatric Information for X-ray Imaging Device Premarket Notifications," dated November 28, 2017"

Non-clinical validation testing has been performed to validate that DVAS conform to the intended use, claims, user needs, effectiveness of safety measures and instructions for use.

As a results, all test results were satisfactory and the result of bench tests indicates that the new device is as safe and effective as the predicate device.

#### 9. Conclusion

In reference to the comparison information provided in the substantial equivalence chart, and the most of functions and electronic features are similar with the predicate device. We believe that the DVAS are safe and effective as predicate device, and have no new indication for use. Therefore, DVAS are substantially equivalent to predicate device.
