    THE INFO IN THIS REPORT WAS PROVIDED TO US BY THE COOK FACILITY IN (B)(4) ON BEHALF OF A MEDICAL FACILITY IN (B)(6). (B)(4). EVAL: OUR EVAL OF THE RETURNED DEVICE CONFIRMED THE REPORT OF INCORRECT CUTTING WIRE ORIENTATION. DURING OUR 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 4.2MM IN DIAMETER (MODEL NUMBER OLYMPUS TJF-140R). THE CATHETER EXITED THE ENDOSCOPE WITH THE CUTTING WIRE FACING 3:00. (APPROPRIATE ORIENTATION IS APPROX 11:00 - 1:00 O'CLOCK.) A DISCREPANCY OR ANOMALY THAT COULD HAVE CONTRIBUTED TO THIS OBSERVATION WAS NOT FOUND DURING OUR LABORATORY ANALYSIS. AFTER A REVIEW OF THE DEVICE HISTORY RECORD FOR THE LOT NUMBER SAID TO BE INVOLVED, WE CAN REPORT NO DISCREPANCIES OR ANOMALIES WERE OBSERVED. WE WERE UNABLE TO CONDUCT A SAMPLE TEST FROM THIS LOT BECAUSE NONE OF THE PRODUCT FROM THIS LOT REMAINED IN FINISHED GOODS INVENTORY. CONCLUSIONS: 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 INCLUDED 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 SUBJECT 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 MFG REQUIREMENTS PRIOR TO SHIPMENT. CORRECTIVE ACTION: A CORRECTIVE ACTION HAS BEEN IMPLEMENTED IN AN EFFORT TO REDUCE OCCURRENCES OF THIS NATURE. THIS PRODUCT WAS MFG PRIOR TO IMPLEMENTATION OF THIS CORRECTIVE ACTION. CUSTOMER QUALITY ASSURANCE WILL CONTINUE TO MONITOR FOR COMPLAINT TRENDS.

    Description of Event or Problem · 1

    DURING AN ENDOSCOPIC RETROGRADE CHOLANGIOPANCREATOGRAPHY (ERCP), THE PHYSICIAN USED A COOK ENDOSCOPY FUSION OMNI-TOME SPHINCTEROTOME. THE USER REPORTED THE TIP OF THE SPHINCTEROTOME WAS POINTING IN THE WRONG DIRECTION AND THEY WERE UNABLE TO USE IT FOR CANNULATION. THE SPHINCTEROTOME WAS REMOVED FROM THE ENDOSCOPE AND ANOTHER SPHINCTEROTOME WAS USED TO COMPLETE THE PROCEDURE. A SECTION OF THE DEVICE DID NOT REMAIN INSIDE THE PT'S BODY. THE PT DID NOT REQUIRE ANY ADDITIONAL PROCEDURE DUE TO THIS OCCURRENCE. ACCORDING TO THE INITIAL RPTR, THE PT DID NOT EXPERIENCE ANY ADVERSE EFFECTS DUE TO THIS OCCURRENCE.
