Exotherme™ is a transcutaneous vascular laser, dedicated to spider veins and telangiectasias, up to 2mm of diameter, for a safe, efficient 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).
Indications
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.
Example of telangiectasias on the leg
Advantages
The auto-regulated cooling system allows to:
protect the epidermis
make 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
Technology
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.
