Advanced Diode Lasers for Varicose Veins Treatment – 980nm & 1470nm (EVLT)
What is EVLT?
Endovenous laser treatment (EVLT) is a procedure that uses laser heat to treat varicose veins. It is a minimally invasive
procedure that makes use of catheters, lasers, and ultrasound to treat varicose veins. This procedure is performed most
often on veins that are still relatively straight and untwisted.
Endovenous Laser Treatment (EVLT) is a non-surgical, outpatient laser treatment for varicose veins. It utilizes ultrasound-guided
technology to precisely deliver laser energy that targets malfunctioning veins and causes them to collapse. Once closed,
the blood flow is naturally redirected to healthier veins.
- Streamlined form factor fits the modern practice environment—and it’s compact enough to transport between hospital and office.
- Intuitive touchscreen controls and custom treatment parameters.
- Preset capability enables quick and easy laser adjustments to suit individual preferences in multiple-practitioner practices and treatment types.
As a water-specific laser, the 1470 Lassev laser targets water as the chromophore to absorb the laser energy. Since the vein structure is mostly water, it is theorized that the 1470 nm laser wavelength efficiently heats endothelial cells with a low risk of collateral damage, resulting in an optimal vein ablation
It is designed to work exclusively with the range of AngioDynamics fibers, including the NeverTouch* fibers. Maximizing these two technologies can result in even better patient outcomes The 1470 nm laser allows effective vein ablation with the targeted energy of 30-50 joules/cm at a setting of 5-7 watts.

For the treatment
An imaging method, such as ultrasound, is used to guide the procedure.
The leg to be treated is injected with numbing medicine.
Once your leg is numb, a needle makes a small hole (puncture) in the vein to be treated.
The catheter containing the laser heat source is inserted into your vein.
More numbing medicine may be injected around the vein.
Once the catheter is in the right position, it's then slowly drawn backward. As the catheter sends out heat, the vein is closed off.
In some cases, other side branch varicose veins may be removed or tied off through several small cuts (incisions).
When the treatment is done, the catheter is removed. Pressure is applied to the insertion site to stop any bleeding.
An elastic compression stocking or a bandage may then be put on your leg.
Treating vein disease with EVLT offers patients numerous benefits, including a success rate of up to 98% percent,
NO hospitalization, and a quick recovery with strong patient satisfaction.
