Exotherme™ is a transdermal vascular laser, specifically for spider veins and varicose veins, up to 2mm in diameter, for safe, effective and painless treatment.

Principle
The principle of the Exotherme™ laser is based on the thermal action of the laser. The transcutaneous irradiation (with a penetration of 1 to 2 mm in the tissue) causes tissue selective absorption by hemeglobin (hemoglobin is the main target of the laser).
The effect of selective photocoagulation is based on two effects:
- Conversion of light energy into heat,
- Coagulation of the vascular wall with collagen denaturation.
Selective photocoagulation does not cause purpura (contrary to photothermolysis).

The superficial vessels, from 0.2 to 2 mm of diameter.
- Spider veins
- Telangectasias
Exotherme™ is cleared on the US market for the photocoaguation of leg telangiecatasias.

The auto-regulated cooling system allows to:
- protect the epidermis
- nmake the treatment painless
- use higher fluencies
- make the treatment reproducible without discomfort for the patient cause no inflammatory reaction
The built-in camera allows:
- on screen visualization
- to target more precisely
- to control the dosimetry (spasm of the vein)
- the patients to watch their treatments in real time
- to give value to the act because the patient see the immediate effects of the laser.
The Multipulse Mode:
- More efficiency of the laser
- Reduction of the energy of the laser by a factory of 3 to 4
- Increased safety for surrounding tissue

A combination of efficient techniques:
- On-screen visualization of the treatment
- Optical zoom x10
- Auto-regulated cooling system
- Multipulse Mode
Multipulse Mode: Special sequence of laser shots:
- The 1st pulse increases the absorption of the blood. (absorption is multiplied by 3 – 4) → Selective absorption
- 2nd and 3rd pulses: maintain the elevation of temperature in the vessel.
