Intended Use

Secret RF Smartcure Applicator is intended for use in dermatologic and general surgical procedures for electro-coagulation and hemostasis

Device Story

Secret RF Smartcure Applicator is an accessory for the Secret RF system; enables monopolar RF energy delivery for electro-coagulation and hemostasis. System comprises main unit, handpiece, and disposable monopolar micro-needle electrodes. Physician operates handpiece, placing electrodes in light contact with epidermis at right angles to target tissue. RF energy passes through skin, generating electro-thermal reaction to coagulate tissue. Device used in clinical settings. Output allows precise thermal coagulation of dermal tissue. Benefits include controlled hemostasis and coagulation in dermatologic/surgical procedures.

Clinical Evidence

Bench testing included biocompatibility (ISO 10993-1), electrical safety (IEC 60601-1), electromagnetic compatibility (IEC 60601-1-2), and high-frequency surgical equipment standards (IEC 60601-2-2). In vivo animal study (micropig model) evaluated histological depth and zone of ablation/thermal damage at low, mid, and high power intensities at immediate, 7-day, and 14-day post-treatment intervals.

Technological Characteristics

High-frequency (RF) electrosurgical accessory. Operates at 2MHz or 4MHz (±10%). Monopolar micro-needle electrodes constructed of stainless steel 304 with Teflon PTFE insulating coating. Single-use, EO gas sterilized. Max power 18W-45W depending on mode. Connects to Secret RF main unit via handpiece.

#### VI. DEVICE DESCRIPTION

Secret RF's High Frequency(=Radio Frequency) includes the system main body, a handpices with singleuse micro-needle type electrodes, footswitch and an LCD touch screen control panel.

The HF 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 HF energy passes through the skin, it generates an electro thermal reaction, which is capable of coagulating the tissue. Using the micro needle tip, the Secret RF system creates heat within the target dermal tissue via micro-needles inserted from the tip.

The Secret RF is consists of ;

- 1) Secret RF main unit (FDA cleared K170325)
- 2) Bipolar type handpieces with Bipolar type micro-needle electrodes (FDA cleared K170325)
- 3) Secret RF Smartcure applicator

The Secret RF Smartcure Applicator consists of :

- Smartcure handpiece
- Monopolar type micro-needle electrodes

(MTR-AC-01 , MTR-AC-04, MTR-AC-27G, K3i)

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

#### VII. INDICATIONS FOR USE

Secret RF Smartcure Applicator is intended for use in dermatologic and general surgical procedures for electro-coagulation and hemostasis

### COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE VIII. DEVICE
