Endovenous laser therapy (EVLT) is a modern, safe and effective method of treating varicose veins of lower limbs.
Dual Wavelength Laser TRIANGEL V6: Most Versatile Medical Laser in the Market
The most important feature of Model V6 laser diode is its dual wavelength which allows it to be used for a variety of tissue interactions. While the 980 nm wavelength has a great affinity for pigments like haemoglobin, the 1470 nm has great affinity for water.
Using TRIANGEL device, the surgeons can either use a single wavelength or both, based on the ailment and the treatment plan. Either way, the device offers precise incision, excision, vaporisation, haemostasis, and tissue coagulation.
These advanced settings give a lot of freedom to the medical practitioners thus allowing them to choose the wavelengths and the modes based on the case.
TRIANGEL EVLT BREAKTHROUGH
EVLT (Endovenous Laser Treatment) is a procedure leading to occlusion of varicose veins. It involves putting a fiber optic into a saphenous vein through a catheter. Then the laser is turned on and slowly withdrawed from the vein.
Thanks to light-tissue interaction mainly thermal effects occur, the tissue is heated and the walls of the vein shrink, because of alteration of endothelium and contraction of collagen. There are two possibilities of performing the treatment: with pulsed and continuous-wave laser operation. Using the pulsed operation also the fiber is withdrawed step by step. A better choice is to use continuous-wave laser and to withdraw the fiber also continuously, what provides more homogenous illumination of the vein, less tissue damaged outside the vein and better results. The therapy is just a beginning of the occlusion process. After the treatment the veins are shrinking for several days or weeks. That is why in the long period observation very good results are obtained. 
Advantages of laser therapy in vascular surgery
State-of-the-art equipment for unprecedented precision
High precision due to strong laser beam focusing capability
High selectivity – affecting only those tissues that absorb the laser wavelength used
Pulse mode operation to protect adjacent tissues from thermal damage
The ability to affect tissues without physical contact with the patient’s body improves sterility
More patients qualified for this type of procedure as opposed to conventional surgery
