In particular, in the actively deflecting portion and in the hand piece of the flexible endoscope there is acute angulation of the working channel. If the guide wire being back loaded into the endoscope is stiff, there is a chance of perforation. This will result in leakage of irrigant into the fiber optic compartment of the endoscope with degradation of the optical image over time and ultimate loss of the endoscope.” Michael Grasso, III, M.D. NYU Medical Center New York, NY * Used to straighten tortuous ureter to have a straighter access. * The conical shape of the catheter tip give a seal to t
