    CONCOMITANT MEDICAL PRODUCTS: BOSTON SCIENTIFIC NOVA WIRE GUIDE, 0.018 MODEL. INVESTIGATION EVALUATION: OUR EVALUATION OF THE RETURNED DEVICE WAS UNABLE TO CONFIRM THE REPORT OF INCORRECT CUTTING WIRE ORIENTATION. DURING THE LABORATORY ANALYSIS, THE SPHINCTEROTOME WAS ADVANCED THROUGH A DUODENOSCOPE THAT IS PLACED IN A SIMULATED BILIARY POSITION. THE DUODENOSCOPE HAS AN ACCESSORY CHANNEL THAT IS 4.2 MM IN DIAMETER (MODEL NUMBER OLYMPUS TJF-160V). THE CATHETER EXITED THE ENDOSCOPE WITH THE CUTTING WIRE FACING 1 O'CLOCK. THE DEVICE WAS THEN BOWED AND THE CUTTING WIRE WAS FACING 1 O'CLOCK (APPROPRIATE ORIENTATION IS APPROXIMATELY 11:00 - 1:00 O'CLOCK). THE SPHINCTEROTOME CATHETER WAS SUBJECTED TO A CLOSE VISUAL EXAMINATION AND TWISTING OF THE TUBING WAS NOT OBSERVED. A DISCREPANCY OR ANOMALY THAT COULD HAVE CONTRIBUTED TO THE REPORTED EVENT WAS NOT FOUND DURING OUR LABORATORY ANALYSIS OF THE RETURNED PRODUCT. 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 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. IMPROPER CUTTING WIRE ORIENTATION CAN OCCUR IF THE DISTAL END OF THE CATHETER IS SHAPED MANUALLY. THIS SPHINCTEROTOME CATHETER IS PRE-CURVED AND IS PROVIDED WITH A PRE-CURVED STYLET IN THE DISTAL TIP OF THE CATHETER. THIS OBVIATES THE NEED FOR MANUAL FORMATION. THE INSTRUCTIONS FOR USE CONTAIN THE FOLLOWING COMMENT: ¿DO NOT APPLY MANUAL PRESSURE TO TIP OR CUTTING WIRE OF SPHINCTEROTOME TO INFLUENCE ORIENTATION, AS THIS MAY RESULT IN DAMAGE TO DEVICE.¿ OTHER FACTORS THAT CAN CONTRIBUTE TO IMPROPER CUTTING WIRE ORIENTATION 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 WITH THE FOLLOWING STATEMENT: ¿UPON REMOVING DEVICE FROM PACKAGE, UNCOIL AND STRAIGHTEN SPHINCTEROTOME. CAREFULLY REMOVE PRECURVED STYLET FROM CANNULATING TIP.¿ THE INSTRUCTIONS FOR USE CONTAIN THE FOLLOWING COMMENT: "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 UTS PRECURVED ULTRA TAPER SPHINCTEROTOMES ARE SUBJECTED TO A VISUAL INSPECTION AND FUNCTIONAL TEST TO ENSURE DEVICE INTEGRITY. A REVIEW OF THE DEVICE HISTORY RECORD CONFIRMED THAT THE LOT SAID TO BE INVOLVED MET ALL MANUFACTURING REQUIREMENTS PRIOR TO SHIPMENT. CORRECTIVE ACTION: 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.

    Description of Event or Problem · 1

    DURING AN ENDOSCOPIC RETROGRADE CHOLANGIOPANCREATOGRAPHY (ERCP), THE PHYSICIAN USED A COOK UTS PRECURVED ULTRA TAPER SPHINCTEROTOME. THE PHYSICIAN INSERTED THE DEVICE INTO THE ENDOSCOPE AND WHEN IT EXITED THE ENDOSCOPE, IT WAS NOTED THAT THE ORIENTATION WAS NOT CORRECT. IT WENT IN THE OPPOSITE DIRECTION THAN WHAT IT SHOULD HAVE. ANOTHER DEVICE WAS USED TO COMPLETE THE PROCEDURE.
