Dear Moon-young Han:

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 (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/cdrb/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"

### eMVFit

### 510(k) Summary

### 2) Substantial Equivalence Discussion

There are differences on a few things. However, these differences do not affect the significant equivalence of the device and its predicates.

### Note 1: "Weight" and "Dimensions"

Although "Weight" and "Dimensions" of subject device are different from the predicate device, they all comply with IEC 60601-1, IEC 60601-2-2, IEC 60601-2-10 requirements, thus the differences of the function specifications does not raise any safety or effectiveness issue.

## Note 2:

"Vacuum"

The "Vacuum" of the subject device is within the predicate device's vacuum output range or lower than the predicate device's output. Therefore the difference doesn't impact essential performance, basic safety or substantial equivalence.

"RF electrical power"

Although the "RF electrical power" of the subject device is different than in the predicate device, it was all tested and is compliant with IEC 60601-2-2. Therefore the difference doesn't impact essential performance, basic safety or substantial equivalence.

"Cut off Temperature"

The "Cut off Temperature" of the subject device is within the predicate device's cut off temperature range or lower than the predicate device. Therefore the difference doesn't impact essential performance, basic safety or substantial equivalence.

### 3) Conclusion

"Embody System" was chosen as predicate for the subject device in consideration of the intended use, indications, performance and principles of operation. Minor variations between the subject and the predicate device were found and listed within the above discussion. Considerable amount of testing, including electrical safety, electromagnetic compatibility, performance, software verification and validation and usability testing were performed to support the claims of appropriately chosen predicate

device. The test results show that the specifications and performance of eMVFit are as safe and effective as legally marketed predicate devices.

Therefore, it is concluded that the eMVFit is substantially equivalent to the legally marketed predicate devices.

### Non-Clinical (Bench) Performance Data: 7.

As part of demonstrating safety and effectiveness of the eMVFit and in showing substantial equivalence to the predicate device that are subject to this 510(k) submission, we completed a number of non-clinical performance tests against applicable standards.

- Basic safety and essential performance of the eMVFit was tested and evaluated according to the IEC 60601-1:2005/A2:2020.
- Effect to the device by electromagnetic disturbances was tested and evaluated according to the FDA-recognized consensus standard IEC 60601-1-2:2014/A1:2020.
- Particular requirements for the basic safety and essential performance of high frequency surgical equipment and high frequency surgical accessories was tested and evaluated according to the IEC 60601-2-2:2017/A1:2023.
- Risk management was recorded by referring to ISO 14971:2019.
- Usability was documented by referring to IEC 60601-1-6:2010/A2:2020.
- Biocompatibility was tested and evaluated according to ISO 10993-5:2009, ISO 10993-10:2021, and ISO 10993-23:2021.
- Software was tested and evaluated according to IEC 62304:2015
- Content of Premarket Submissions for Device Software Functions

The eMVFit passed all the testing in accordance with internal requirements, national standards, and international standards shown above, to support substantial equivalence of the subject device.

Also, to demonstrate that the eMVFit meets all design specifications and performance requirements, and to measure the accuracy of the output parameters of eMVFit and to compare the output parameters with predicate devices, nonclinical bench testing was performed in accordance with the internal process in compliance with the recommendations of the FDA Guidance for Premarket Notification (510(k)) Submissions for Electrosurgical Devices for General Surgery.

The testing results support that the requirements for performance and electrical safety were met for the acceptance of the device. The eMVFit passed all testing and supports the claims of substantial equivalence to the predicate device.

#### Sterilization/Disinfection/Cleaning/Shelf Life 8.

The eMVFit is intended for multiple use and therefore must be cleaned according to the instructions provided in the device Instructions for Use.

There are no sterilized parts or accessories involved with this device.

#### 9. Biocompatibility
