BUR GUARD, MEDIUM

Additional Manufacturer Narrative

THIS COMPLAINT WAS CONFIRMED. THE RETURNED USED DEVICE, ITEM 00137501200, WAS INSPECTED PER THE SERVICE AND REPAIR PROCEDURE AND FOUND INNER RACE BEARING OUT OF POSITION DUE TO BROKEN BEARING. AS A RESULT, THE BUR COULD NOT BE INSERTED INTO THE BUR GUARD. CONDITION OF THE RETURNED DEVICE PREVENTS FURTHER TESTING; HOWEVER, THIS TYPE OF FAILURE WOULD POTENTIALLY CAUSE THE TEMPERATURE TO INCREASE GREATLY. THE MANUFACTURING DOCUMENTS FROM THE DEVICE HISTORY RECORD HAVE BEEN REVIEWED WITH SPECIAL ATTENTION TO THE MANUFACTURING AND INSPECTION OF THE PRODUCT. THE PRODUCT RELEASED FOR DISTRIBUTION WERE FOUND TO HAVE MET ALL SPECIFICATIONS PRIOR TO SHIPMENT AND FOUND NO ABNORMALITIES THAT WOULD CONTRIBUTE TO THIS ISSUE. A TWO-YEAR LOT HISTORY REVIEW SHOWS THIS IS THE ONLY COMPLAINT FOR THIS DEVICE AND LOT NUMBER COMBINATION AND FAILURE MODE. A TWO-YEAR REVIEW OF COMPLAINT HISTORY REVEALED THERE HAS BEEN A TOTAL OF 34 COMPLAINTS, REGARDING (B)(4) DEVICES, FOR THIS DEVICE FAMILY AND FAILURE MODE. DURING THIS SAME TIME FRAME (B)(4) DEVICES HAVE BEEN MANUFACTURED AND SHIPPED WORLDWIDE. SHOULD ALL THE COMPLAINT DEVICES HAVE BEEN FOUND CONFIRMED FOR THIS REPORTED FAILURE, THE RATE OF FAILURE WOULD BE (B)(4). THE INSTRUCTIONS FOR USE (IFU) PROVIDES THE USER WITH INFORMATION REGARDING PROPER CARE AND USE OF THIS DEVICE. PER THE IFU THE USER IS ALSO ADVISED THAT OVERHEATING MIGHT OCCUR IF BEARINGS ARE WORN OR ARE NOT KEPT CLEAN. IF OVERHEATING OCCURS, DISCONTINUE USE AND RETURN FOR SERVICE. BEFORE EACH USE, BE SURE THAT BURS ARE COMPLETELY SEATED AND LOCKED IN THE INSTRUMENT. IF THE INSTRUMENT IS ACTIVATED WITHOUT THE BUR COMPLETELY SEATED AND LOCKED, THE BUR MAY BE THROWN FROM THE INSTRUMENT WITH GREAT FORCE. ALSO, UNLESS THE BUR IS COMPLETELY LOCKED INTO PLACE, SEVERE OVERHEATING MAY OCCUR. A DETERMINATION FOR FURTHER INVESTIGATION HAS BEEN INITIATED. THIS ISSUE WILL CONTINUE TO BE MONITORED THROUGH THE COMPLAINT SYSTEM TO ASSURE PATIENT SAFETY.
