Abstract
A method is disclosed for treating veins. In the subject method, the skin is pierced with the sharpened tip of a fiber optic probe. The probe is advanced to a location underneath the vessel to be treated. Once in position, the vessel is irradiated with a treatment beam having a fluence sufficient to coagulate and collapse the vessel at that location. The procedure is then repeated at multiple sites along the length of the vessel so that it will collapse along its length and no longer carry any blood. In the preferred embodiment, a curved probe is used to facilitate the insertion of the tip under the vessel.
