Abstract
An optical apparatus functions as a laser catheter for removal, penetration or treatment of human tissue or other biotic material. The arrangement of the optical components, including the focal length of the lens and the spacing between the lens and the source of light is selected to yield an output beam having advantageous characteristics which are particularly suitable for medical laser treatment. Such characteristics include a relatively long beam throw, a long focal range, and a small output beam waist. A hollow tip, preferably conical in shape, is utilized to provide a tactile indicator as to the cutting action of the output beam.
