Exotherme™

Exotherme™ is a transcutaneous vascular laser, dedicated to spider veins and telangiectasias, up to 2mm of diameter, for a safe, efficient and painless treatment.

vascular doctor (Perpignan - France).

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
  • Rosacea

Exotherme™ is cleared on the US market for the photocoaguation of leg telangiecatasias.

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.
