Intended Use

The DEPILASE TWIN YAG Laser System is intended for the coagulation and haemostasis of vascular lesions (1064 and 532 nm wavelengths), the removal and permanent reduction of unwanted hair in Fitzpatrick skin type I - VI and the dermatological use for the non invasive treatment of facial wrinkles (1064 nm wavelength).

Device Story

The DEPILASE TWIN YAG Laser System is a flashlamp-pumped Nd:YAG laser for dermatological procedures. It utilizes an optical cavity with an Nd:YAG crystal, optionally frequency-doubled to 532 nm via a Second Harmonic Crystal (SHC). A red diode aiming beam is co-aligned via a beamsplitter. Energy is delivered via optical fiber to a focusing handpiece for non-contact treatment. The system includes a high-voltage power supply, water-to-air heat exchanger cooling, and a microprocessor-based controller for parameter selection. Operated by clinicians in a medical setting, the device allows precise control of laser pulses (up to 3 Hz). The output is used for vascular coagulation, hair reduction, and wrinkle treatment. The microprocessor ensures regulated power and thermal control, providing consistent energy delivery to target tissues, which facilitates clinical outcomes in dermatological applications.

Clinical Evidence

No clinical data provided; substantial equivalence is based on technological characteristics and intended use comparison to the predicate device.

Technological Characteristics

Flashlamp-pumped Nd:YAG laser; 1064 nm fundamental wavelength, 532 nm frequency-doubled via Second Harmonic Crystal (SHC). Includes red diode aiming beam (Class I). Features high-voltage power supply, internal closed-loop water-to-air heat exchanger, and optical fiber delivery with focusing handpiece. Microprocessor-controlled. Pulse frequency up to 3 Hz. Non-contact operation.

Indications for Use

Indicated for coagulation and haemostasis of vascular lesions (1064/532 nm), permanent hair reduction (Fitzpatrick skin types I-VI), and non-invasive treatment of facial wrinkles (1064 nm).

Regulatory Classification

Identification

#### I. Description

The DEPILASE TWIN YAG Laser System is based on Nd: YAG laser technology. Within the system, an optical cavity contains the Nd: YAG crystal, which is activated by means of the use of a flashlamp, with the option of frequency doubling the fundamental laser wavelength, from 1064 nm to 532 nm. The frequency doubling wavelength is obtained by passing with the laser radiation through a special crystal called Second Harmonic Crystal (SHC). After the cavity, a red diode aiming beam is reflected onto a coaxial beam path using a beamsplitter assembly. The combined therapeutic and aiming beams are guided down an optical fibre delivery system to a focusing handpiece. The laser is used in a non-contact mode.

The DEPILASE TWIN YAG Laser System is designed with 5 major sub-systems:

- a) A high voltage power supply which converts and rectifies the a.c. mains current to provide regulated power for the flashlamp simmer current and main triggering pulse.
- b) A cooling system consisting of an internal water flow circuit together with water to air heat exchanger.
- c) An Nd: YAG laser rod, capable of generating optical pulses at a frequency up to 3 Hz
- d) An optical delivery system, interfacing the energy from the laser to the patient via an optical fibre and focusing handpiece.
- e) The microprocessor based controller which regulates the functions of the laser and allows parameter selection by the user.

## II. Intended Use

The DEPILASE TWIN YAG Laser System is indicated for the use in dermatological applications for the non invasive treatment of facial wrinkles ( 1064 nm laser emission).

### III. Summary of Substantial Equivalence

Depilase believes that its DEPILASE TWIN YAG Laser System is substantially equivalent. regarding the 1064 nm laser emission , to the Laserscope Lyra (K020021) Nd: YAG laser. previously cleared for the use in dermatological applications for the non invasive treatment of facial wrinkles.

It therefore has the same Intended Use as the DEPILASE TWIN YAG Laser System.

Technologically, the predicate device has identical characteristics to the DEPILASE TWIN Y AG Laser System, comprising a flashlamp pumped Nd: Y AG laser rod generating light at a wavelength of 1064 nm, which is subsequently delivered to the patient via an optical fibre delivery system and focusing handpiece.

The DEPILASE TWIN YAG Laser System output characteristics are very similar to those of the predicate device.

All lasers are microprocessor controlled devices.

All lasers utilize Class I aiming beams which pose no hazard to the user.

All systems utilize an internal closed loop water-air heat exchange circuit for optimal thermal control of the laser cavity.

The risk and benefits of the DEPILASE TWIN YAG Laser System are comparable to the predicate device when used for similar clinical applications.

It is therefore believed that there are no new questions of Safety or Effectiveness raised by the introduction of this device.
