Intended Use

The NuEra Tight RF Family is intended: - to provide topical heating for the purpose of elevating tissue temperature for the treatment of selected medical conditions such as temporary relief of pain, muscle spasms, and increase in local circulation; - to provide, with a massage device, a temporary reduction in the appearance of cellulite.

Device Story

NuEra Tight RF Family is a radiofrequency (RF) generator system used by clinicians to deliver localized heat to subcutaneous tissue. The device utilizes capacitive (monopolar) or resistive (bipolar) electrodes to elevate tissue temperature up to 45°C. The system includes various handpieces for different body areas and an optional massage handpiece for cellulite reduction. A return plate is required for capacitive mode. The device is operated via a touch screen GUI or an optional footswitch. The clinician applies a conductive cream to the treatment area to facilitate heat transfer. By warming the tissue, the device aims to relieve pain, reduce muscle spasms, and improve local circulation. The subject device introduces a sterile, single-use disposable tip for the small area handpiece to mitigate infection risks compared to the previously cleared reusable tip.

Clinical Evidence

Bench testing only. Functional testing confirmed that the small area handpiece tip maintains skin temperature within the specified range (+/- 2°C of set point) for 15 minutes across all RF frequencies (470 kHz, 1 MHz, 2 MHz, 4 MHz, 6 MHz) following EtO sterilization. Sterilization validation, package integrity, and shelf-life testing were performed in accordance with ISO 11607, ISO 11135-1, and ISO 10993-7.

Technological Characteristics

Radiofrequency generator system; capacitive (monopolar) and resistive (bipolar) electrodes; frequencies: 470 kHz, 1 MHz, 2 MHz, 4 MHz, 6 MHz; max power 250 W; Class I type BF electrical protection; touch screen interface; EtO sterilization for disposable tips; ASTM F1980 for shelf-life; ISO 11138-1/2/7 for sterilization validation.

Indications for Use

Indicated for patients requiring topical heating for temporary relief of pain, muscle spasms, and increased local circulation, or for temporary reduction in the appearance of cellulite when used with a massage device.

## Device Description

NuEra Tight RF Family is a family of devices designed to:

- develop localized heat to warm the subcutaneous tissue by means of radio frequency energy, delivered through electrodes in contact with the patient.
Specifically, there are two devices in the family:

- -NuEra Tight RF - radiofrequency generator with single RF electrode connector
- -NuEra Tight RF Plus - radiofrequency generator with single RF electrode connector. The device has a different design, in particular for larger size, than the NuEra Tight RF, for the presence of an additional electronic part that is cleared under K201239.

The purpose of the treatment based on the radiofrequency system (NuEra Tight) is to raise the temperature inside the tissues up to maximum of 45℃. Therefore, depending on the treatment and intended use, different parts of the body can be treated.

{4}------------------------------------------------

The devices use RF electrodes of the capacitive (or monopolar) and resistive (or bipolar) types. Capacitive RF electrodes have different sizes and plug into an RF handpiece that provides connection to the RF generator (through the electrode connectors). Handpieces of different shapes are available to facilitate use by the operator on different body parts.

The small area handpiece tip is provided sterile and disposable. The tip is Eto sterilized, the sterilization process was verified and validated using FDA-recognized standards UNI EN ISO 11138-1, UNI EN ISO 11138-2 and UNI EN ISO 11138-7. Also, the package integrity and shelf-life for this change have been evaluated through accelerated aging using American Society for Testing and Materials (ASTM) F1980.

Capacitive electrodes work in combination with a return plate that must be in contact with the patient's body during the treatment in order to close the circuit with the RF generator. Return plates can be reusable or disposable, with specific connectors on the front tray. One resistive electrode is provided fixed to a dedicated handpiece intended for the treatment of small body areas. The resistive electrode, being bipolar, is not meant to work with the return plate. One massage handpiece is provided to be used to add a mechanical treatment to the heat emission. All the handpieces are used with a small amount (approximately 1 mm layer) of cream, that is Parker Redux cream K782055. The cream purpose is to provide aid to transfer the heat.

A footswitch is provided as an optional user interface that allows to start and stop the medical treatment. It can be used as an alternative to the GUI start and stop button.

The pause handpiece can be used to pause the treatment without using the GUI.

## Indications for Use

The NuEra Tight RF Family is intended:

- . to provide topical heating for the purpose of elevating tissue temperature for the treatment of selected medical conditions such as temporary relief of pain, muscle spasms, and increase in local circulation;
- . to provide, with a massage device, a temporary reduction in the appearance of cellulite.

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

The difference is the introduction of a sterile and disposable configuration for the small area handpiece tip instead of the already cleared multiuse tip. The introduction of a sterile single use tip in place of the previous reusable tip to the cleared small area handpiece is to avoid to be carrier of bacteria and virus in sensitive and vulnerable areas of the body.

The indications for use and materials of construction remain unchanged from the cleared device. this difference does not, therefore, raise any new types of safety or effectiveness questions.

## Performance Data and Bench Test

## Functional Testing

Functional test has been performed to confirm that the performance of the NuEra Tight RF Family device. using the small area handpiece, is not impacted from the introduction of the sterilization process. Tips, after sterilization process, have been tested in order to demonstrate that the device can maintain the set skin temperature at 2 set point (minimum: 40°C and maximum: 42°C) and it can maintain the skin temperature inside that interval of + 2°C for 15 minutes.

The test is executed for all RF frequencies used with the small area handpiece (470 kHz, 1 Mhz, 2 Mhz, 4 MHz and 6 MHz).

## Sterilization validation and shelf-life

Ethylene Oxide sterilization and Shelf-life validation activities for the new disposable configuration of the small area handpiece tip were conducted by external laboratories. Testing results demonstrate compliance with the following recognized FDA Standards:

ISO 11607, FDA standards recognition # 14-530

ISO 11135-1, FDA standards recognition # 14-529

ISO 10993-7, FDA standards recognition # 2-275

{7}------------------------------------------------

A summary of all the verification and validation activities performed on the NuEra Tight RF family are listed in Table 2 below.

| Test name | Test Description |
|--------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| Functional testing | The temperature stability in all operative status (multifrequency) and with all available electrodes provided with the devices was fully verified, validated and submitted under the NuEra Tight RF family submission K200359. The same protocol has been used to verify the performance of the small area handpiece tip, before and after the sterilization process. |
| Sterilization | Sterilization process validation of the small area handpiece tip was completed using an established method (EO). Package integrity testing and shelf-life validation has been performed. Testing results demonstrate compliance with ISO 11607, ISO 11135-1, and ISO 10993. |

## Conclusion

Based upon the indications for use, the known technical information and the performed tests listed above based on well-established methods and standards, the NuEra Tight RF Family device has been shown to be substantially equivalent to currently marketed predicate device. The only difference which is the introduction of the small area handpiece tip sterile and disposable in place of the previous not sterile and reusable one is considered minor and do not raise new issues of the safety and effectiveness of the NuEra Tight RF Family devices when compared to the predicate device.
