METHOD AND APPARATUS FOR SELECTIVE PHOTOTHERMOLYSIS OF VEINS
First Claim
1. A method for treating at least one vein, comprising:
- directing an electromagnetic radiation to a tissue containing the at least one vein, wherein the radiation has at least one characteristic which effectuates an absorption by the at least one vein more effectively than by an artery.

Abstract
A system and method are provided that are capable of selectively treating a vein using photothermolysis techniques, where an electromagnetic radiation is applied to tissue containing the vein. The radiation can be selected so that it may be more effectively absorbed by veins as compared to arteries. Thus, unwanted thermal damage to arteries in the vicinity of the vein being treated can be reduced or avoided. The radiation can have a frequency of approximately 654 nm, which can provide a ratio of absorption by veins to absorption by arteries of about 3.7. Other wavelengths near 654 nm may be provided, for example, which can have an absorption ratio greater than, e.g., about 3.3 to 3.6.
