Intended Use

ACUTRON is intended for use in dermatologic and general surgical procedures for electro-coagulation and hemostasis

Device Story

ACUTRON is a high-frequency (RF) electrosurgical system for dermatologic and general surgical procedures. The system comprises a main unit, a footswitch, an LCD touch screen control panel, and a handpiece with single-use monopolar micro-needle electrodes. The physician operates the device by placing the micro-needle tip in light contact with the epidermis at a right angle to the target tissue. RF energy (2MHz) is delivered through the needles to generate an electro-thermal reaction, coagulating dermal tissue. The device is used in clinical settings to achieve hemostasis and tissue coagulation. The output is controlled via the touch screen and activated by the footswitch. The device benefits patients by providing a controlled method for surgical coagulation.

Clinical Evidence

Bench testing only. No clinical data provided. Safety and performance verified via IEC 60601-1, IEC 60601-1-2, and IEC 60601-2-2 standards. Biocompatibility and ex-vivo histology testing were leveraged from the predicate device (K182355).

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/cdrl/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.

#### II. DEVICE DESCRIPTION

ACUTRON is High Frequency(=Radio Frequency, RF) includes the system main body, a handpieces with single-use micro-needle type electrodes, footswitch and an LCD touch screen control panel.

The RF energy is delivered to the target tissue using a handpiece and disposable tip(micro needle electrode tip), the tip being placed in light contact with the epidermis and the handpiece being held at right angles to the target tissue. As the RF energy passes through the skin, it generates an electro thermal reaction, which is capable of coagulating the tissue.

Using the micro needle tip, the ACUTRON creates heat within the target dermal tissue via micro-needles inserted from the tip.

The ACUTRON is consists of ;

- 1) Main unit
- 2) Smartcure handpiece(FDA cleared K182355)
- 3) Monopolar type micro-needle electrodes(FDA cleared K182355)

ACUTRON has the same technical specifications and same indications for use as those of the predicate device and the reference device.

The main differences are:

- Change in the dimension of the device -
- Change in GUI design -
- 1. Main unit(RF console)

ACUTRON has been specifically designed for the Secret RF Smartcure applicator handpieces, the predicate device (K182355) and identical operating specifications compared with the Secret RF system, the reference device (K170325). Electrical and mechanical safety and performance of ACUTRON electrosurgical system have been verified according to international standards.

- 2. Handpiece
ACUTRON handpieces include the identical handpiece needles cleared for the predicate device, Smartcure Applicator (K182355). Therefore, ACUTRON handpieces are subject to the same biocompatibility, sterilization, cleaning, shelf-life performance validation testing for the Smartcure Applicator handpieces, the predicate device, K182355.

- 3. GUI Design
ACUTRON has been specifically designed for the Secret RF Smartcure applicator handpieces, the predicate device(K182355). The normal mode is identical to the SC mode of the Secret RF system , the reference device(K170325).

#### VI. PERFORMANCE DATA

Design verification process were performed following risk assessment to verify that no new questions of safety and effectiveness have been raised due to the modifications

{8}------------------------------------------------

introduced.

### Biocompatibility testing:

The patient contact components and materials are identical to the predicate device. The biocompatibility is being leveraged from the predicate device.

### Non Clinical testing:

IEC 60601-1: 2005, AMD 1: 2012 Medical Electrical Equipment was performed for General Requirements for basic safety and essential performance. The requirements of specified standards were fulfilled.

IEC 60601-1-2: 2014 Medical Electrical Equipment was performed for General Requirements for basic safety and essential performance (collateral standards: electromagnetic compatibility.

IEC 60601-2-2: 2017 Medical electrical equipment Part 2: Particular requirements for the basic safety and essential performance of high-frequency surgical equipment and high-frequency surgical accessories.

### Animal testing:

Ex-vivo histology testing for ACUTRON handpieces is being leveraged from the Smartcure Applicator handpieces, the predicate device.

#### VII. CONCLUSIONS

There are no significant differences between ACUTRON and the predicate device and the reference device.

The proposed device does not raise any additional questions regarding safety and effectiveness. ACUTRON has the same indication of use and shares the same technological characteristics as the predicate devices.

In accordance with the Federal Food, Drug and Cosmetic Act, 21 CFR Part 807 and based on the information provided in this premarket notification, it is the opinion of Ilooda Co, Ltd. that ACUTRON is substantially equivalent in comparison with the predicate device and the reference device as described herein.
