The 200 µm SmartFiber is designed to give complete deflection for flexible ureteroscopes and its tiny outer diameter of 400 µm ensures large irrigation flow. The 272 µm SmartFiber is a tiny fiber having high yield continuity. The 365 µm SmartFiber generates highest laser power in smallest diameter. The 550 µm SmartFiber is exclusively designed to apply on tissue application by means of rigid endoscopes.
