SureFlex™ Fibers FAQ

Common Questions and Troubleshooting

Question: Why is the aiming beam not visible at distal end of fiber?

Solution: This could be caused by a misalignment of the laser output spot and the fiber input. Disconnect the fiber from the SMA-905 connector, rotate and reconnect the fiber to the laser.

Question: What do I do to minimize breaks at the proximal end of the flexible ureteroscope during use?

Solution: Damage may occur if excessive force is applied along the fiber length i.e. stepping on the fiber, bumping the fiber near the connector, or using hemostats or clamps directly on the fiber. Use care when positioning the laser console and the fiber to minimize such hazards.

Question: How do I correct for decreased laser fiber efficacy during a procedure?

Solution: Remove the fiber and inspect the distal end. If the tip appears damaged, use aseptice technique and a sterile Fiber Cleaver and Stripper per the instructions supplied with the accessories. If this does not resolve the issue, replace the entire fiber.

Problem: How can I minimize fiber burn through or breakage when inserted into the cystoscope?

Solution: Too much deflection of a medium to large core fiber can lead to fiber burn through and breakage. We recommend that 550µm and 910µm fibers be used in rigid scopes only, and that use of our 150µm and 200µm SureFlex fibers be for lower pole work only. In addition use the lowest power setting which are effective and never exceed the recommended maximum settings for each fiber size.
