1. EVLT Technology Principle

How Does Endovenous Laser Treatment Work?

Varicose veins are usually caused by damaged venous valves, which result in blood reflux and increased venous pressure.

EVLT uses controlled laser energy to treat the affected vein:

Step 1 — Fiber Placement

A laser fiber is inserted into the target vein through a small puncture under ultrasound guidance.

Step 2 — Laser Energy Delivery

The diode laser delivers thermal energy through the fiber.

Step 3 — Vein Wall Heating

Laser energy is absorbed by tissue components, generating controlled heat.

Step 4 — Vein Closure

The heated vein wall contracts and gradually closes.

Step 5 — Blood Flow Redirection

Blood circulation is naturally redirected through healthy veins.

FAQ

1. What is EVLT laser treatment?

EVLT (Endovenous Laser Treatment) is a minimally invasive procedure that uses laser energy delivered through a fiber inserted into a diseased vein. The laser creates controlled thermal energy, causing the vein wall to contract and close. Blood is then naturally redirected through healthier veins.

2. What wavelengths does this EVLT laser system use?

This system uses three wavelengths: 980nm + 1470nm + 635nm.

• 1470nm: Mainly absorbed by water in the vein wall, providing precise thermal ablation.
• 980nm: More absorbed by hemoglobin, supporting coagulation and vascular treatment.
• 635nm: Visible aiming beam for accurate fiber positioning.

3. Why combine 980nm and 1470nm wavelengths?

The combination of 980nm and 1470nm provides complementary absorption characteristics.

• 1470nm focuses on water absorption in vascular tissue for controlled vein wall heating.
• 980nm provides stronger hemoglobin absorption for coagulation effects.

The dual treatment mechanism allows physicians to select suitable settings according to different clinical requirements.

4. What is the output power of this EVLT laser machine?

The standard configuration provides 30W maximum laser output power, offering stable and efficient energy delivery for endovenous laser procedures.
