Medical endo-vascular instrument for laser treatment of varicose veins, comprises optical fiber with rigid support The instrument optical fiber has a rigid support. It is connected to a light source, a laser. The support is a rigid tubular needle encasing the optical fiber. The optical fiber includes a covering of the needle internal wall, made of silica. Light is emitted at the front, from the beveled end of the needle or fiber, which can be rotated. The optical fiber can be extended from the end of the needle. Anesthetic can be injected and correct positioning can be verified. The source, a laser, operates at a wavelength between 800 and 890 nm.
