    THE INSTRUMENT WAS RETURNED AND EVALUATED. PER THE CUSTOMER REPORTED COMPLAINT, FAILURE ANALYSIS FOUND THAT THE ONE GRIP WAS BENT, CAUSING SIDE-TO-SIDE MISALIGNMENT OF THE GRIPS. THERE WAS A .052 OFFSET AT THE TIPS. THE BENT GRIP DID NOT EXHIBIT SEPARATION OF THE YAW PULLEY AND PULLEY COVER AT THE GLUE JOINT; HOWEVER, THE LIKELY CAUSE OF BENDING REMAINS OVERLOADING AT THE TIP. THE INSTRUMENT PASSED ELECTRICAL CONTINUITY TESTING. THE EVIDENCE WAS INCONCLUSIVE, BUT THE DAMAGE WAS LIKELY DUE TO MISHANDLING/MISUSE. 48, 80 - FAILURE ANALYSIS ALSO OBSERVED THAT THE DISTAL END OF THE MAIN TUBE HAD VARIOUS SCRATCH MARKS WITH LIGHT MATERIAL REMOVAL. THE SCRATCHES WERE .122 - .194 IN LENGTH AND NOT ALIGNED WITH THE TUBE AXIS. THE EVIDENCE WAS INCONCLUSIVE, BUT THE DAMAGE WAS LIKELY DUE TO MISHANDLING/MISUSE. NO OTHER DAMAGE WAS FOUND. THE ENDOWRIST INSTRUMENTS INSTRUCTIONS FOR USE (IFU) SPECIFICALLY STATES: GENERAL PRECAUTIONS AND WARNINGS - HANDLE INSTRUMENTS WITH CARE. AVOID MECHANICAL SHOCK OR STRESS THAT CAN CAUSE DAMAGE TO THE INSTRUMENTS. THE CUSTOMER REPORTED COMPLAINT DOES NOT ITSELF CONSTITUTE A MDR REPORTABLE EVENT; HOWEVER, THE ENTER FAILURE INFORMATION HERE, SUCH AS TUBE ABRASIONS, FOUND DURING FAILURE ANALYSIS EVALUATION COULD LIKELY CAUSE OR CONTRIBUTE TO AN ADVERSE EVENT IF THE FAILURE MODE WERE TO RECUR.
