ABSTRACT OF THE DISCLOSURE A device for terminating a surgical apparatus such as a fiber optic catheter is disclosed. A fiber optic catheter having an outer lumen, an inner lumen disposed within the outer lumen, and optical fibers between the lumens is terminated at its distal end with a two-piece tip. An outer band of the tip has one end between the outer lumen and the optical fibers, while an inner band contacts the ends of the inner lumen and the optical fibers. The terminal faces of the optical fibers may be angled to increase the surface area illuminated or ablated by the fiber optic catheter. The inner and outer bands may be flared outwardly to increase the surface area affected even more. The inner lumen may also be extended beyond the terminal face to aid tracking of the catheter. The inner lumen and inner band may be eccentric to the outer lumen and outer band so that the catheter may be rotated to ablate a larger vascular area. - 19 -
