SUBSTANTIAL EQUIVALENCE COMPARISON AND DISCUSSION

{5}------------------------------------------------

* current between two monopolar electrodes

Any differences between the APEX 6 and the predicate 4-channel devices do not raise new issues of safety or effectiveness. The APEX 6 uses the same amount of energy output across 6 channels and delivers this energy sequentially as opposed to continuously. Therefore, the APEX 6 is substantially equivalent to the predicate device based upon the Indication for Use, technology, functional modes, hardware and software components, and performance.

{6}------------------------------------------------

### PERFORMANCE TESTING

Bench - Bench testing supports that the APEX 6 performs as expected. Safety was tested in accordance with Standard for Medical electrical equipment - Part 1: General requirements for basic safety and essential performance ANSI/AAMI 60601-1:2005 + Cl:2009 + A2:2010 + Al:2012, CAN/CSA-C22.2 No. 60601-1:2014 and the Standard for Medical Electrical Equipment - Part 2-2: Particular requirements for the basic safety and essential performance of high frequency surgical equipment and high frequency surgical accessories ANSI/AAMI 60601-2-2:2017, CAN/CSA-C22.2 No. 60601-2-2:2019. EMC was tested in accordance with IEC 60601-1-2:2014/ EN 60601-1-2:2015/IEC 60601-2-2.

| Lesion size | Purpose was to document the maximum<br>linear dimensions in all three planes as<br>well as the volume for the affected tissue<br>region and compare them to the<br>predicate device for minimal, typical, and<br>maximum energy delivery | Analysis: All affected area differences were less<br>than 1 mm. Minor errors can introduced by:<br>• Measuring small diameters with fuzzy borders<br>can increase the measurement error.<br>• For volume, a 10% error in the linear<br>dimensions will result in a 33% error in volume.<br>Therefore this study confirms that the Apex 6<br>and the predicate device are substantially<br>equivalent in regards to affected tissue size. |
| Comparison<br>of treatment<br>times<br>between<br>NeuroTherm<br>NT 2000<br>and Apex 6 | The purpose of this protocol is to<br>measure and compare the time to ramp<br>up to set temperature of the Apex 6 and<br>the predicate device under worse case<br>conditions to evaluate the efficiency of<br>energy delivery and measure treatment<br>times. | Results demonstrated that the APEX 6 was<br>substantially equivalent in terms of treatment<br>times compared to the predicate device. |
| Design<br>Validation<br>Review | A documented review of device<br>acceptance criteria was performed to<br>confirm compliance with the following<br>plans:<br>• Requirement Specification<br>• Requirements, Design and Verification<br>Traceability Matrix<br>• Embedded Software Requirement<br>Specification<br>• GUI Software Requirement<br>Specification<br>• Embedded Software Validation Plan<br>• GUI Software Validation Plan<br>• Instructions for Use | The finished unit design review verified that all<br>documented device requirements were met. |

Software - Software testing supports that the APEX 6 performs as expected. Validation was performed to the FDA Moderate Level of Concern per the FDA software guidance for the Content of Premarket Submissions for Software Contained in Medical Devices

CLINICAL TESTING Not required.

### CONCLUSION

The APEX 6 is similar to or the same as the predicate device as follows:

- . Technology
- Intended use/Indication for Use
- Technical specifications, or ranges of technical specifications
- . Functional modes compared to 4-channel devices

The fundamental technological characteristics of the APEX 6 are substantially equivalent to the predicate device based upon the Indication for Use, technology, functional modes, hardware components, and performance. Therefore, the APEX 6 is substantially equivalent to the predicate device.
