Abstract
A method and device for selective photothermolysis of a surgical target within surrounding tissue. The target and the surrounding tissue are heated to about 60.degree. C. Then the target is heated to the point of coagulation, preferably by monochromatic light. The temperature difference between the coagulating target and the surrounding tissue is sufficiently mild that heat diffusing out of the target does not damage the surrounding tissue, even in the case of a relatively large target such as varicose veins.
