    PRODUCT ANALYSIS OF NV-4-10-HELIX, LOTNO:226824988 FOUND THE CONCERTO PUSHER BROKEN AT THE BREAK INDICATOR WITH THE PROXIMAL SEGMENT (ACTUATOR INTERFACE, POSITIVE LOAD INDICATOR AND PART OF THE BREAK INDICATOR) NOT RETURNED FOR ANALYSIS. THE RELEASE WIRE AND COIN WERE FULLY RETRACTED OUT OF THE LUMEN STOP/PUSHER AND NOT RETURNED FOR ANALYSIS. THE SHIELD COIL WAS FOUND DAMAGED. THE IMPLANT COIL WAS ALREADY DETACHED AND NOT RETURNED FOR ANALYSIS. THE SHRINK TUBING WAS REMOVED, AND THE LUMEN STOP WAS OBSERVED TO BE DAMAGED (OVALIZED). DRIED BLOOD WAS FOUND WITHIN THE LUMEN STOP. BASED ON THE CUSTOMER REPORT AND DEVICE ANALYSIS, THE CUSTOMER REPORT OF "PREMATURE DETACH FROM A NON-DETACHMENT" WAS CONFIRMED AS THE DAMAGES FOUND IS CONSISTENT WITH THIS FAILURE. THE DAMAGED LUMEN STOP IS INDICATIVE OF THE COIN BECOMING STUCK WITHIN THE LUMEN STOP. ANOTHER POSSIBLE CAUSE OF NON-DETACHMENT IS THE DAMAGED SHIELD COIL BECOMING ENTANGLED WITH THE PROXIMAL END OF THE IMPLANT COIL, PREVENTING IT FROM FULLY DETACHING. IT IS LIKELY THE REPORTED LATE DETACHMENT OCCURRED DUE TO MANIPULATION OF THE COIL DEVICE WITHIN THE MICRO CATHETER CAUSING THE IMPLANT COIL TO BECOME DISLODGED FROM THE SHIELD COIL OR THE COIN TO RELEASE FROM THE LUMEN STOP. THE DRIED BLOOD FOUND WITHIN THE LUMEN STOP COULD HAVE ALSO CONTRIBUTED TOWARDS THE REPORTED PREMATURE DETACH FROM A NON-DETACH. AS THE PROXIMAL PUSHER SEGMENT, RELEASE WIRE/COIN, AND INSTANT DETACHER USED DURING THE EVENT WERE NOT RETURNED FOR ANALYSIS, ANY CONTRIBUTION OF THE PROXIMAL PUSHER, RELEASE WIRE/COIN AND INSTANT DETACHER TO THE REPORTED FAILURE COULD NOT BE ASSESSED. MEDTRONIC IS SUBMITTING THIS REPORT TO COMPLY WITH FDA REPORTING REGULATIONS UNDER 21 CFR PARTS 4 AND 803.
