1940nm EVLT Diode Laser for Varicose Vein Treatment & Endovenous Thermal Ablation
The exceptional efficacy of the 1940 nm laser is rooted in its unique physical characteristics. This wavelength aligns with the peak absorption band of water molecules, enabling highly efficient and rapid energy absorption within biological tissues. When the laser is delivered into the target area, its energy is instantly absorbed by the tissue's intracellular and extracellular water content, ensuring precise thermal action with superior clinical selectivity and minimal collateral damage.
1. Precision Energy Delivery: The 1940 nm laser beam penetrates the skin and is preferentially absorbed by intracellular and extracellular water within the target vein wall.
2. Direct Vessel Wall Closure: Laser energy is rapidly converted into heat, concentrated directly on the venous wall. This results in instantaneous dehydration, collagen contraction, and coagulative necrosis.
3. Progressive Fibrosis and Clearance: The occluded vein transforms into a fibrous cord that is naturally resorbed by physiological metabolic processes.
