Intended Use

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

Device Story

The DEPILASE TWIN LASE Laser System is a dual-wavelength surgical laser utilizing Nd:YAG (1064 nm) and Alexandrite (755 nm) crystals. Flashlamp-pumped optical cavities generate laser pulses; a red diode aiming beam is reflected via a beamsplitter onto a coaxial path. Energy is delivered through an optical fiber to a noncontact focusing handpiece. A microprocessor-based controller manages laser functions and parameter selection. The system includes a high-voltage power supply and an internal water-to-air heat exchanger for cooling. Operated by clinicians in a medical setting, the device allows for the treatment of vascular lesions and hair removal. The output is used by the physician to target specific tissues, facilitating coagulation, hemostasis, or hair follicle destruction, thereby providing therapeutic benefits for dermatological conditions.

Clinical Evidence

Bench testing only. No clinical data provided.

Technological Characteristics

Dual-wavelength laser system (Nd:YAG 1064 nm, Alexandrite 755 nm). Flashlamp-pumped. Microprocessor-controlled. Internal closed-loop water-to-air heat exchange cooling system. Class I diode aiming beam. Noncontact focusing handpiece with optical fiber delivery. Standalone system.

Indications for Use

Indicated for coagulation and haemostasis of vascular lesions and removal/permanent reduction of unwanted hair in patients with Fitzpatrick skin types I-VI, including those with suntanned skin.

Regulatory Classification

Identification

FEB 2 2 2002### I. Description

The DEPILASE TWIN LASE Laser System is based on Nd: YAG and Alexandrite laser technology. Within the system, one optical cavity contains the Nd: YAG crystal, and another optical cavity contains the Alexandrite crystal, which are activated by means of the use of a flashlamp. After each 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 individual optical fibre delivery system to a focusing handpiece. The laser is used in a noncontact mode.

The DEPILASE TWIN LASE Laser System is designed with 6 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 2 Hz.
- d) An Alexandrite laser rod, capable of generating optical pulses at a frequency up to 2 Hz.
- e) Two optical delivery systems, interfacing the energy from each laser cavity to the patient via an indipendent optical fibre and focusing handpiece.
- f) The microprocessor based controller which regulates the functions of the laser and allows parameter selection by the user.

### II. Intended Use

The DEPILASE TWIN LASE Laser System is indicated for the coagulation and haemostasis of vascular lesions and 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 LASE Laser System is substantially equivalent, regarding the Nd: YAG laser emission, to the Laserscope Lyra (K990718), and Altus Medical Aesthetic CoolGlide (K991798) Nd: YAG Lasers previously cleared for both the coagulation and hemostasis of vascular lesions and the removal and permanent reduction of unwanted hair in Fitzpatrick skin types I - VI, including suntanned skin types, and regarding the Alexandrite laser emission, to the Candela GenteLASE GL (K994260), GenteLASE II (K984601) and the Cynosure Apogee TSK (K992757) Alexandrite lasers, all previously cleared for the removal of unwanted hair in Fitzpatrick skin types I - IV

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

Technologically, the predicate devices have identical characteristics to the DEPILASE TWIN LASE Laser System, all comprising a flashlamp pumped Nd: YAG laser rod generating light at a wavelength of 1064 nm, or a flashlamp pumped Alexandrite laser rod generating light at a wavelength of 755 nm which is subsequently delivered to the patient via an individual optical fibre delivery system and focusing handpiece.

The DEPILASE TWIN LASE Laser System output characteristics are very similar to those of the 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 LASE 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.
