The SLIMUS device incorporates a laser system that emits a 1060 nm wavelength using a diode laser. Laser radiation is emitted from the laser main unit to the device's handpieces through the handpiece fibers. The device is used to noninvasively reduce the size of the waist of overweight patients with a Body Mass Index (BMI) of less than 30 (kg/m²). A vibrator function is installed inside of each hand-piece and operable only in non-laser output mode. The device's handpieces are fixed to a belt which then combined provide mechanical vibration to the patient in order provide relief from minor muscle aches and pains.

AI/ML Overview

This document does not contain information about acceptance criteria or a study proving the device meets acceptance criteria. It is a 510(k) premarket notification summary for the SLIMUS device, primarily demonstrating its substantial equivalence to a predicate device (SculpSure™).

Specifically, the document states in section 8: "No Clinical performance testing was performed." This means there isn't a study proving the device's performance against specific acceptance criteria in a clinical setting provided in this document.

Therefore, I cannot provide the requested information in the table or answer the questions related to clinical study design, as no such study is presented in this document. The provided text focuses on non-clinical testing and technological comparisons to establish substantial equivalence.

Dear Sanghwa Myung:

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 (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 located 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.

{1}------------------------------------------------

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 of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 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-device-safety/medical-device-reportingmdr-how-report-medical-device-problems.

For comprehensive regulatory information about medical devices and radiation-emitting products, including information about labeling regulations, please see Device Advice (https://www.fda.gov/medicaldevices/device-advice-comprehensive-regulatory-assistance) and CDRH Learn (https://www.fda.gov/training-and-continuing-education/cdrh-learn). Additionally, you may contact the Division of Industry and Consumer Education (DICE) to ask a question about a specific regulatory topic. See the DICE website (https://www.fda.gov/medical-device-advice-comprehensive-regulatoryassistance/contact-us-division-industry-and-consumer-education-dice) for more information or contact DICE by email (DICE@fda.hhs.gov) or phone (1-800-638-2041 or 301-796-7100).

8. No Clinical performance testing was performed.

9. Discussion of non-clinical testing.

The non-clinical data for the SLIMUS device, including bench testing, electrical medical device safety, electromagnetic field compatibility, laser safety, biocompatibility, hardware, and software documentation together support that the device can perform as intended.

10. Conclusions

The SLIMUS device shares the same intended use and similar technological characteristics with the predicate device. These do not raise new types of questions regarding safety and efficacy for the SLIMUS when compared to the predicate. Based on its technical characteristics, indications for use, and performance data, the SLIMUS device is considered to be substantially equivalent to the predicate device.
