A method of endovenous laser treatment in disclosed. An introducer sheathis introduced into a vein and an optical fiberis introduced through the introducer sheath until a first markingon the optical fiberindicates that the distal end of the optical fiberis substantially in alignment with the distal end of the introducer sheath. The introducer sheathis then withdrawn relative to the optical fiberuntil a second markingon the optical fiberindicates that the distal end of the optical fiberextends a predetermined distance beyond the distal end of said introducer sheath. Laser radiation is passed down the optical fiberso that laser radiation is delivered to the inner wall of the vein and the introducer sheathtogether with the optical fiberare withdrawn a certain distance along the vein.

Method of endovenous laser treatment

A medical laser device is disclosed comprising an optical fiberhaving markingswhich enable the optical fiberto be accurately positioned relative to an introducer sheathThe introducer sheathmay also have graduated markings to enable the sheathto be withdrawn at a controlled rate. A pulsed or continuous laser source may be provided.

Medical laser device

A method is disclosed for treating blood vessels using endovascular techniques to deliver laser energy. Percutaneous access into the vein lumen will be obtained using an angiocatheter through which a fiber optic line will be introduced. The vein will be emptied of blood using elevation of the limb, patient positioning, compression, or other means. Laser energy will be delivered into the vein lumen using wavelengths from about 532 nanometers to about 1064 nanometers. Sufficient power and duration will be used to damage the entire thickness of the vein wall, ultimately causing fibrosis of the treated blood vessel. Fibrosis of the treated blood vessel causes the blood vessel to decrease in diameter or collapse.
