Abstract
The invention relates to a catheter device including an optical fiber whose distal end is disposed within a hollow tube with a sharp or needle shaped distal end, which can penetrate tissue. The distal end of the optical fiber and the hollow tube are configured so as to emit, by refraction (total internal reflection) or reflection from a metal surface, laser energy at an angle of about 80° to about 90° relative to the longitudinal axis of the optical fiber and hollow tube. The hollow tube is mounted to a housing and may be surrounded by a sheath.
