Abstract
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.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
106 words
A fiber optic probe for use in treating blood vessels under the skin comprising: a hollow tubular member having a sharpened needle-shaped tip configured for piercing the skin thereby permitting the tubular member to be advanced along side of a blood vessel located under the skin; and an optical fiber supported within the tubular member, said optical fiber for transmitting laser radiation from an input end to a delivery end and wherein the delivery end terminates within the tubular member, said delivery end being configured to direct most of the laser radiation emitted therefrom along an axis transverse to said tubular member and towards said vessel.
Claim 2
Dependent Claim
106 words

Claim 3
Dependent Claim
18 words
A fiber optic probe as recited in claim 1 wherein the end of said tubular member is curved.
