    Additional Manufacturer Narrative · 1

    PATIENT IDENTIFIER, PATIENT AGE, DATE OF BIRTH, GENDER AND WEIGHT ARE UNKNOWN. PATIENT IS OVER 18 YEARS OLD. A VISUAL EXAMINATION REVEALED THAT THE WORKING LENGTH WAS TWISTED, THE EXPOSED CUT WIRE WAS DISCOLORED AND APPEARED TO HAVE MELTED/SPLIT THE EXTRUSION AT THE DISTAL PIERCE HOLE. THE MELTED EXTRUSION, CREATED A TEAR MEASURING APPROXIMATELY 6MM PROXIMALLY FROM THE DISTAL PIERCE HOLE. THIS TEAR CAUSED THE CUTTING WIRE ANCHOR TO SLIDE PROXIMALLY FROM THE DISTAL PIERCE HOLE AND SHORTENED THE EXPOSED CUTTING WIRE LENGTH, WHICH NOW DOES NOT MEET SPECIFICATION. A FUNCTIONAL EVALUATION FOUND THAT THE DEVICE DID NOT MEET THE BOWING SPECIFICATION AS A RESULT OF THE MELTED/SPLIT EXTRUSION. THE CONDITION OF THE RETURNED INCIDENT DEVICE WAS CONSISTENT WITH THE COMPLAINT THAT THE DEVICE CUT WIRE WOULD NOT BOW HOWEVER THIS WAS ATTRIBUTED TO MELTED/SPLIT EXTRUSION. DURING MANUFACTURING, TOME DEVICES ARE 100% INSPECTED, THE MELTED/SPLIT EXTRUSION IS LIKELY DUE TO PROCEDURAL FACTORS. THEREFORE, THE MOST PROBABLE ROOT CAUSE IS OPERATIONAL CONTEXT. THE DEVICE HISTORY RECORD WAS REVIEWED AND FOUND TO MEET ALL MANUFACTURING SPECIFICATIONS. A SEARCH OF THE COMPLAINT DATABASE REVEALED THAT NO SIMILAR COMPLAINTS EXIST FOR THE SPECIFIED LOT.
