    A PRODUCT EVALUATION WAS NOT PERFORMED IN RESPONSE TO THIS REPORT BECAUSE THE PRODUCT SAID TO BE INVOLVED WAS NOT PROVIDED TO COOK FOR EVALUATION. THE REPORT COULD NOT BE CONFIRMED. A REVIEW OF THE DEVICE HISTORY RECORD COULD NOT BE CONDUCTED BECAUSE THE LOT NUMBER WAS NOT PROVIDED. INVESTIGATION CONCLUSIONS: WE COULD NOT CONDUCT A COMPLETE INVESTIGATION BECAUSE THE PRODUCT SAID TO BE INVOLVED WAS NOT RETURNED FOR EVALUATION. A DEFINITIVE CAUSE FOR THE REPORTED OBSERVATION COULD NOT BE DETERMINED. 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: "NOTE: DO NOT APPLY MANUAL PRESSURE TO TIP OR CUTTING WIRE OF THE 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 TO UNCOIL AND STRAIGHTEN THE SPHINCTEROTOME UPON REMOVING THE DEVICE FROM THE PACKAGING. THE USER IS THEN INSTRUCTED TO CAREFULLY REMOVE THE PRECURVED STYLET FROM THE 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 FUSION OMNI-TOME SPHINCTEROTOMES ARE SUBJECTED TO A VISUAL INSPECTION AND FUNCTIONAL TEST TO ENSURE DEVICE INTEGRITY. 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 FUSION OMNI-TOME SPHINCTEROTOME. ONCE THE SPHINCTEROTOME WAS ADVANCED THROUGH THE ENDOSCOPE AND AFTER CANNULATION WAS PERFORMED, AT THIS POINT, IT WAS TIME TO PERFORM THE SPHINCTEROTOMY. WHEN THE NURSE BOWED THE SPHINCTEROTOME, THE ORIENTATION OF THE CUTTING WIRE WENT TOWARDS THE 2 O'CLOCK POSITION (IT SHOULD BE AT 11 O'CLOCK). THE PHYSICIAN WAS ABLE TO MANIPULATE THE DEVICE JUST ENOUGH TO COMPLETE THE PROCEDURE WITH THE COMPLAINT DEVICE. A SECTION OF THE DEVICE DID NOT REMAIN INSIDE THE PATIENT'S BODY. THE PATIENT DID NOT REQUIRE ANY ADDITIONAL PROCEDURES DUE TO THIS OCCURRENCE. ACCORDING TO THE INITIAL REPORTER, THE PATIENT DID NOT EXPERIENCE ANY ADVERSE EFFECTS DUE TO THIS OCCURRENCE.
