    THREE OPENED KNIVES, IN BLISTERS WITH BLADE OUT OF SHEATHING AND TIP THROUGH TYVEK WERE RECEIVED FOR THE REPORT OF BLUNT KNIVES. SAMPLES WERE VISUALLY INSPECTED AND FOUND TO BE NONCONFORMING. SAMPLE 1-3 - BLADE HAD DAMAGED TIP AND DAMAGED CUTTING EDGE. PENETRATION TESTING COULD NOT BE PERFORMED DUE TO THE DAMAGE OF THE SAMPLES. A REVIEW OF THE DEVICE HISTORY RECORD TRACEABLE TO THE REPORTED LOT NUMBERS, INDICATES THAT THE REPORTED PRODUCT WAS PROCESSED AND RELEASED ACCORDING TO THE REPORTED 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 PRODUCT IS IMPROPERLY REMOVED OR INSERTED AFTER USE, OR IMPROPER HANDLING, OR CONTACT WITH ANOTHER INSTRUMENT DURING SURGERY OR SET-UP. THE DAMAGE SEEN ON THE RETURNED COMPLAINT SAMPLE COULD HAVE CONTRIBUTED TO THE CUSTOMERS REPORTED ISSUE OF BLUNT KNIVES. THE EXACT ROOT CAUSE FOR THE DAMAGED KNIFE SAMPLE 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 EDGE EXHIBITED ON THE RETURNED OPENED SAMPLE, 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). H.10 REFLECTS ALL RELATED REPORT NUMBERS ASSOCIATED WITH THIS PRODUCT EVENT THAT HAVE BEEN SUBMITTED AT THIS TIME.
