Abstract
Consistent with the present invention, a tube is provided that contains both a sensing and a laser delivery fiber to the target area. The length of the tube can be varied to any desired length. The end portion of the tube includes a second piece, which is a cap having two through holes or passages. These holes can be formed by standard machining or micromaching methods. The first hole can accommodate the sensing fiber, while the second hole contains the laser delivery fiber. The first and second holes extend in first and second directions, respectively, and form an angle therebetween such that the sensor fiber viewing area is within the radiation area created by the laser delivery fiber. Accordingly, the sensor fiber receives energy emitted from a central portion of the radiation area so that the temperature of the exposed tissue can be accurately determined.
