The SabreGuard and SabreLine holmium laser fibers provide solutions for urological laser procedures, offering single-use and reusable options to meet clinical requirements. SabreGuard fibers use a rounded tip that protects deflected ureteroscopes and enables smooth navigation, while SabreLine fibers include radius and straight tips for flexibility. All fibers are tested for power output and feature SMA-905 connectors compatible with cleared surgical lasers. Their smaller diameters improve irrigation and visibility. With core sizes from 150 to 940 microns, the fibers deliver precise laser energy for effective stone fragmentation and soft tissue applications in modern surgical settings. These designs help reduce scope damage and enhance procedural efficiency.
