## Intended Use

The DEPILASE TWIN YAG Laser System is intended for the coagulation and haemostasis of vascular lesions (1064 and 532 nm wavelengths) and the removal and permanent reduction of unwanted hair in Fitzpatrick skin types I -VI, including suntanned skin types (1064 nm wavelength).

## Device Story

The DEPILASE TWIN YAG Laser System is a flashlamp-pumped Nd:YAG laser for dermatological surgery. It generates 1064 nm laser radiation, with an optional frequency-doubling Second Harmonic Crystal (SHC) to produce 532 nm. A red diode aiming beam is co-axially aligned. Energy is delivered via an optical fiber and focusing handpiece in non-contact mode. The system includes a high-voltage power supply, internal water-to-air heat exchanger cooling, and a microprocessor-based controller for parameter selection. Operated by clinicians in a clinical setting, the device allows for precise coagulation of vascular lesions and permanent hair reduction. The microprocessor regulates laser functions, ensuring controlled energy delivery to the target tissue. Benefits include effective treatment of vascular lesions and hair reduction across all Fitzpatrick skin types.

## Clinical Evidence

No clinical data provided; substantial equivalence is based on technological characteristics and performance similarities to legally marketed predicate devices.

## Technological Characteristics

Flashlamp-pumped Nd:YAG laser; 1064 nm fundamental wavelength; 532 nm frequency-doubled wavelength via Second Harmonic Crystal (SHC); optical fiber delivery; focusing handpiece; internal closed-loop water-to-air heat exchanger; microprocessor-controlled; Class I aiming beam.

## Regulatory Identification

(1) A carbon dioxide laser for use in general surgery and in dermatology is a laser device intended to cut, destroy, or remove tissue by light energy emitted by carbon dioxide.(2) An argon laser for use in dermatology is a laser device intended to destroy or coagulate tissue by light energy emitted by argon.

## Predicate Devices

#### 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 warelonging 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 (SHO). 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.

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

The DEPILASE TWIN YAG Laser System is indicated for the coagulation and haemostasis of vascular lesions and/or the removal and permanent reduction of unwanted hair in Fitzpatrick skin types I - VI, including suntanned skin types.

### III. Summary of Substantial Equivalence

Depilase believes that its DEPILASE TWIN YAG Laser System is substantially equivalent, Doprade Done res that laser emission , to the Laserscope Lyra (K990718) and Altus Medical Aesthetic CoolGlide (K991798) Nd: YAG lasers, previously cleared for both the coagulation and haemostasis of vascular lesions and/or the removal and permanent reduction of unwanted hair in Fitzpatrick skin types I - VI, including suntanned skin types, and regarding the 532 nm laser President to the Fotona Dualis KTP ( K011939) previously cleared for the coagulation and haemostasis of vascular lesions

They therefore have the same Intended Use as the DEPILASE TWIN YAG Laser System.

Technologically, the predicate devices have identical characteristics to the DEPILASE TWIN YAG Laser System, all comprising a flashlamp pumped Nd: YAG laser rod generating light at a wavelength of 1064nm or 532 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 predicate devices.

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 devices 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.
