Embodiment Construction
[0050] In the treatment of varicose veins, the size of the optical fiber used will vary depending on the diameter of the vein to be treated. To treat veins up to 3 or 4 mm in size, a 400-micron optical fiber is inserted into the vein. For veins greater than 4 mm a 600-micron fiber is used.
[0051] The laser is set on continuous pulse mode with a working time of 0.3 seconds and an idle time of 0.3 seconds. The laser output power is varied depending upon vein size. For a vein less than 4 mm in diameter, 7-10 joules of power is needed; for veins greater than 4 mm in diameter, 12-15 joules are needed.
[0052] Prior to treatment, abnormal lengths of the vein are identified from prior examinations. Power requirements as described above and a preferred pull-out speed is determined. Local anesthetic is then applied along the marked line of treatment. Next, the course of the vein is detected and treated as follows: the optical fiber is inserted into the vein and the laser is set to single pulse ...
