    Additional Manufacturer Narrative · 0

    TWO OPENED KNIFE SAMPLES WERE RECEIVED IN BLISTERS FOR THE REPORT OF BLUNT KNIVES. ONE KNIFE WAS RECEIVED LOOSE IN A BLISTER AND ONE KNIFE WAS RECEIVED IN A BLADE PROTECTOR TRAY. THE RETURNED SAMPLES WERE VISUALLY INSPECTED AND WERE FOUND TO BE NONCONFORMING WITH A DAMAGED TIP AND/OR DAMAGED CUTTING EDGES. PENETRATION TESTING COULD NOT BE PERFORMED DUE TO THE DAMAGED CONDITION OF THE SAMPLES. PHOTOS ATTACHED TO THE PARENT COMPLAINT WERE REVIEWED BY THE MANUFACTURING SITE. THERE ARE SIX PHOTOS ATTACHED. THE PHOTOS CONFIRM THE PRODUCT AND LOT NUMBERS FOR THIS FILE (QS (B)(4)) AND QS FILES: (B)(4). THE REPORTED ISSUE COULD NOT BE CONFIRMED FROM THE PHOTOS. A REVIEW OF THE DEVICE HISTORY RECORD RELATED TO THE REPORTED LOT NUMBER INDICATES THAT THE PRODUCT WAS PROCESSED AND RELEASED ACCORDING TO THE PRODUCT¿S ACCEPTANCE CRITERIA. THE EXACT ROOT CAUSE COULD NOT BE DETERMINED FROM THE INVESTIGATION PERFORMED. THE DAMAGE TO THE RETURNED SAMPLES IS CONSISTENT WITH DAMAGE THAT CAN OCCUR WHEN THE BLADE CONTACTS A HARD SURFACE SUCH AS THE PROTECTIVE BLADE TRAY WHEN THE PRODUCT IS IMPROPERLY REMOVED OR INSERTED AFTER USE, FROM IMPROPER HANDLING OR FROM CONTACT WITH ANOTHER INSTRUMENT DURING SURGERY OR SET-UP. THE EXACT ROOT CAUSE FOR THE DAMAGED KNIFE SAMPLES IS UNKNOWN THEREFORE, SPECIFIC ACTION WITH REGARDS TO THIS COMPLAINT CANNOT BE TAKEN. ALL KNIVES ARE 100% INSPECTED BY TRAINED OPERATORS USING A MINIMUM OF 10X MAGNIFICATION DURING MANUFACTURING. ANY NONCONFORMANCE, SUCH AS THE DAMAGED TIP AND DAMAGED CUTTING EDGES EXHIBITED ON THE RETURNED OPENED SAMPLES, IS REMOVED FROM THE LOT AND SCRAPPED. FUNCTIONAL PENETRATION TESTING IS PERFORMED AND MONITORED DURING THE FINISHING PROCESS TO ENSURE THE SHARPNESS OF THE PRODUCT. COMPLAINTS ARE REVIEWED AND MONITORED AT REGULAR INTERVALS FOR ANY SIGNIFICANT ADVERSE TRENDS. THE MANUFACTURER INTERNAL REFERENCE NUMBER IS: (B)(4).
