    Additional Manufacturer Narrative · 1

    THE INSTRUMENT WAS RETURNED AND EVALUATED. FAILURE ANALYSIS CONFIRMED THE REPORTED COMPLAINT. THE PITCH CABLE WAS BROKEN AT THE PROXIMAL CLEVIS HUB. THE CLEVIS DID NOT EXHIBIT ANY WEAR. FRAYED STRANDS STUCK OUT AT THE INSTRUMENT'S WRIST. OTHER CABLES AT THE WRIST WERE NOT DAMAGED. AN ADDITIONAL OBSERVATION NOT REPORTED WAS THE TIPS OF THE INSTRUMENTS GRIPS WERE BENT. ONE GRIP WAS BENT, CAUSING A SIDE TO SIDE MISALIGNMENT OF THE GRIPS. THERE WAS A .027 OFFSET AT THE TIP. THE BENT GRIP DID NOT EXHIBIT SEPARATION OF THE YAW PULLEY AND PULLEY COVER; HOWEVER, THE LIKELY CAUSE OF BENDING IS OVERLOADING AT THE TIP. FAILURE ANALYSIS CONCLUDED THE DAMAGE MAY BE DUE TO MISHANDLING / MISUSE. 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. AN ADDITIONAL FINDING WAS VARIOUS SCRATCHES ON THE DISTAL END OF THE MAIN TUBE EXHIBITING LIGHT MATERIAL REMOVAL. THE SCRATCHES WERE NOT AXIALLY ALIGNED WITH THE TUBE AXIS. NO OTHER DAMAGE WAS FOUND. THE CUSTOMER REPORTED COMPLAINT DOES NOT ITSELF CONSTITUTE A MDR REPORTABLE EVENT; HOWEVER; THE BROKEN CABLE AND THE ADDITIONAL FINDING OF TUBE ABRASIONS WITH MATERIAL REMOVED, FOUND DURING FAILURE ANALYSIS EVALUATION COULD LIKELY CAUSE OR CONTRIBUTE TO AN ADVERSE EVENT IF THE FAILURE MODE WERE TO RECUR.
