    PMA/510(K) # K172665. INVESTIGATION EVALUATION: OUR LABORATORY EVALUATION OF THE PRODUCT SAID TO BE INVOLVED CONFIRMED THE CUTTING WIRE SECURING COMPONENT LOCATED NEAR THE DISTAL END OF THE SPHINCTEROTOME HAS DISCONNECTED FROM THE CATHETER. DUE TO THE CATHETER AND SECURING COMPONENT DISCONNECTION, THE DISTAL END OF THE CUTTING WIRE IS NO LONGER CONNECTED TO THE SPHINCTEROTOME CATHETER AT THE DISTAL END. THE SECURING COMPONENT HAS A LONGER SECTION MEASURING 3 MM AND A SHORTER SECTION MEASURING 2 MM THEREFORE NO PART OF THE DEVICE IS MISSING. THE CUTTING WIRE ALSO EXHIBITS SLIGHT EVIDENCE OF A CAUTERY APPLICATION (BLACKENING OF THE CUTTING WIRE WAS NOTED). A PRODUCT DISCREPANCY OR ANOMALY THAT COULD HAVE CONTRIBUTED TO THIS REPORTED OCCURRENCE WAS NOT OBSERVED. THE DEVICE HISTORY RECORD FOR THE LOT NUMBER SAID TO BE INVOLVED WAS REVIEWED. A DISCREPANCY OR ANOMALY WAS NOT OBSERVED WITH THE PRODUCT THAT WAS RELEASED FOR DISTRIBUTION. INVESTIGATION CONCLUSION: A VISUAL EXAMINATION OF THE RETURNED DEVICE CONFIRMED THE CUTTING WIRE SECURING COMPONENT HAS SEPARATED FROM THE CATHETER. A DEFINITIVE CAUSE FOR THIS OBSERVATION COULD NOT BE DETERMINED BECAUSE THE ACTUAL USE CONDITIONS COULD NOT BE DUPLICATED IN THE LABORATORY SETTING. DUE TO A VARIETY OF CLINICAL CONDITIONS SUCH AS PATIENT ANATOMY, ENDOSCOPE POSITION OR PROGRESSION OF DISEASE STATE, WE COULD NOT REPRODUCE THE ACTUAL CONDITIONS OF PRODUCT USAGE DURING OUR LABORATORY ANALYSIS. THIS LIMITS OUR ABILITY TO CONCLUSIVELY DETERMINE A CAUSE. SEPARATION OF THE CUTTING WIRE SECURING COMPONENT AND THE CATHETER CAN OCCUR IF THE TIP OF THE SPHINCTEROTOME IS OVER FLEXED. THE INSTRUCTIONS FOR USE CAUTION THE USER: "DO NOT OVER FLEX OR BOW TIP BEYOND 90 DEGREES, AS THIS MAY DAMAGE OR CAUSE CUTTING WIRE TO BREAK." OTHER FACTORS THAT CAN CONTRIBUTE TO SEPARATION OF THE CUTTING WIRE SECURING COMPONENT AND THE CATHETER INCLUDE MANIPULATING THE HANDLE WITH THE CATHETER IN A COILED POSITION OR WITH THE PRECURVED STYLET INSIDE THE CANNULATING TIP. THE INSTRUCTIONS FOR USE ADVISE THE USER: "UPON REMOVING DEVICE FROM PACKAGE, UNCOIL AND STRAIGHTEN SPHINCTEROTOME. CAREFULLY REMOVE PRECURVED STYLET FROM CANNULATING TIP." THE INSTRUCTIONS FOR USE CONTAIN THE FOLLOWING COMMENT: "NOTE: DO NOT EXERCISE HANDLE WHILE DEVICE IS COILED OR PRECURVED STYLET IS IN PLACE, AS THIS MAY CAUSE DAMAGE TO SPHINCTEROTOME AND RENDER IT INOPERABLE." PRIOR TO DISTRIBUTION, ALL TRI-TOME PC TRIPLE LUMEN SPHINCTEROTOMES ARE SUBJECTED TO A VISUAL INSPECTION AND FUNCTIONAL TEST TO ENSURE DEVICE INTEGRITY. THE FUNCTIONAL TEST INCLUDES BOWING THE SPHINCTEROTOME TO ENSURE THE DISTAL END RESPONDS TO HANDLE MANIPULATION. A REVIEW OF THE DEVICE HISTORY RECORD CONFIRMED THAT THE LOT SAID TO BE INVOLVED MET ALL MANUFACTURING REQUIREMENTS PRIOR TO SHIPMENT. CORRECTIVE ACTION: A REVIEW OF THE COMPLAINT HISTORY WAS CONDUCTED. THE LIKELIHOOD OF OCCURRENCE IS CONSIDERED RARE. CORRECTIVE ACTION IS NOT WARRANTED AT THIS TIME BASED ON THE QUALITY ENGINEERING RISK ASSESSMENT. QUALITY ASSURANCE WILL CONTINUE TO MONITOR FOR COMPLAINT TRENDS AND REASSESS THE RISK ASSESSMENT RESULTS AS POST MARKET FEEDBACK CONTINUES TO BECOME AVAILABLE.
