Dear Diane Davis:

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.

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

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).

K223138 AB1 Electrosurgical Instrument, Creo Electrosurgical System, Product Code NEY

#### DEVICE DESCRIPTION SUMMARY

The CROMA Electrosurgical Generator is an Electrosurgical unit (ESU) to be used with compatible electrosurgical instruments and accessories.

The CROMA Electrosurgical Generator is a tabletop, non-network connected, mains powered ESU. It comprises two distinct energy sources for the independent generation of bipolar radiofrequency (RF) and microwave (MW) energies, intended to supply electrosurgical power for cutting, and ablation of soft tissues, when connected to compatible instruments via the interface cable.

The CROMA Electrosurgical Generator incorporates proprietary software developed by Creo Medical Ltd.

The CROMA Electrosurgical Generator subject of this submission incorporates a new front panel, which has been updated from a Vacuum Fluorescent Display (VFD) in the predicate device to a Liquid Crystal Display (LCD) screen in the subject device.

The subject and predicate devices have identical principles of operations:

- Supply suitable Creo Medical instruments with appropriate power for their surgical uses at a MW frequency of 5.8 GHz for the purpose of coagulation, cauterisation and/or ablation.
- . Supply suitable Creo Medical instruments with appropriate power for their surgical uses at a nominal RF of 400 kHz for the purpose of cutting.

#### INDICATIONS FOR USE STATEMENT

The CROMA Electrosurgical Generator is intended to provide Radiofrequency (RF) and microwave (MW) energy for cutting, coagulation, and ablation of soft tissue, when used in conjunction with compatible electrosurgical instruments and accessories.

The Creo Medical Electrosurgical System is not intended for use in cardiac procedures.

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

The Reusable Interface Cable is for connection only of a compatible Creo Medical Instrument (Surgical Accessory) to the CROMA Electrosurgical Generator to deliver Radiofrequency (RF) and/or Microwave (MW) energy for the cutting, coagulation and ablation of tissue via endoscopic access.

#### INDICATIONS FOR USE COMPARISON

The subject device has the same Indications for Use as the predicate for use statement for the subject device has been reworded for readability and clarity by removing the specific reference of the compatible instruments. Instead, compatible instruments are provided in a table form in the Instructions for Use, right under the Intended Use Statement.

Therefore, this formatting change does not raise concerns of safety and effectiveness.

#### TECHNOLOGICAL COMPARISON

The subject and predicate devices have the following same technological characteristics:

- . Energy inputs
- Energy outputs
- Principles of operations
- . Functionalities of the control console (front panel), including push buttons, output sockets for interface cable connection, symbols, LED lights and audio tones in compliance with IEC 60601 requirements.

The subject device has been modified to modernise the visual of the user interface and upgrade the screen from a Vacuum Fluorescent Display (VFD) to a Liquid Crystal Display (LCD). As a result, the following technological differences exist between the subject and predicate devices:

- . Front panel screen changed from VFD to LCD
- Front panel keypad membrane updated (aesthetics, features location)
- . Software changed to support the new LCD screen, as well as include other minor software updates

The differences in the subject device technological characteristics do not raise concerns of safety and effectiveness.
