Additional Manufacturer Narrative

(B)(4) SUPPLEMENTAL EMDR AN OS4080-002 BONE HOOK DIA 3/4(1.9CM) BLUNT 9IN DEVICE WAS REPORTED TO HAVE BROKEN APART DURING USE. HOWEVER, A PHYSICAL SAMPLE WAS NOT AVAILABLE FOR EVALUATION AND IN ITS PLACE THREE REPRESENTATIVE PHOTOS WERE PROVIDED FOR REVIEW. ALL PHOTOS WERE OF THE ACTUAL SAMPLE AND IT WAS NOTED THAT THE SAMPLE APPEARED TO BE WRAPPED IN PLASTIC OR INSIDE OF A CLEAR BAG. THE ETCHING WAS DISPLAYED IN THE SAMPLE PHOTOS ON THE APPROPRIATE LOCATION AND DISPLAYED THE MANUFACTURING MARKINGS ALONG WITH THE LOT CODE WHICH WAS NOT INITIALLY REPORTED. LOT CODE WAS FOUND TO BE A01, INDICATING THIS DEVICE WAS LIKELY IN USE FOR OVER 21 YEARS. BASED ON THE EVIDENCE VISIBLE IN THE PHOTOS THE ENGINEER COULD SEE THAT THE DEVICE WAS INSIDE A CLEAR PLASTIC COVERING, AND IT WAS MOST LIKELY AN AUTHENTIC V. MUELLER PRODUCT. HOWEVER, FURTHER INFORMATION SUCH AS WHETHER IT WAS REPAIRED, REFINISHED, TAMPERED WITH, OR THE ACTUAL SURFACE CONDITIONS COULD NOT BE REVIEWED/CONFIRMED, HENCE WERE SUSPECTED. UPON FURTHER INSPECTION OF THE PHOTOS, THE SAMPLE SURFACES WERE ALSO NOTED TO COVERED AND OBSTRUCTED WITH A RED/BROWNISH SUBSTANCE, AND ADDITIONAL SIGNS OF DISCOLORATION AND WEAR ON THE STEEL SURFACES WERE NOTED. FURTHERMORE, THE FAILURE MODE OF THE BROKEN TIP END WAS CONFIRMED IN PHOTO 1 OF 3. APPROXIMATELY, A QUARTER OF AN INCH OF THE HOOK TIP WAS BROKEN OFF AND THE PIECE WAS NOT FURTHER PICTURED. UPON ZOOMING INTO THE PHOTO AS MUCH AS POSSIBLE (190%) BEFORE THE IMAGE TURNED BLURRED AND GRAINY: THE BROKEN END APPEARED TO HAVE BEEN A SLIGHTLY DUCTILE, WITH A DIAGONAL FRACTURE LEAVING A SHEARED END WITH A POINT TO IT. DISCOLORATION OR DARKENING OF THE BROKEN END SURFACES WERE NOTED, AND IT WAS LIKELY OXIDATION THAT IS NORMALLY CAUSED TO UNTREATED/UNFINISHED BROKEN ENDS. OVERALL, THE PHOTO APPEARED TO HAVE BEEN MANUFACTURED NORMALLY WITH THE NORMALLY APPLIED HOOK BEND. FURTHER ANALYSIS OF THE BROKEN END COULD NOT BE PERFORMED DUE TO THE LACK OF A PHYSICAL SAMPLE AVAILABLE FOR TESTING. THE OTHER TWO PHOTOS WERE OF THE SAMPLE HANDLE END WITH THE ETCHING SIDE VISIBLE. BOTH PHOTOS OF THE HANDLE SURFACES WERE NOTED TO BE COVERED IN THE SAME RESIDUE SUBSTANCE AS NOTED ON THE HOOK/SHAFT END. USAGE WEAR, DISCOLORATION, SCRATCHES, AND SLIGHT FADING OF THE ETCHING WERE ALSO OBSERVED. THE SAMPLE¿S AGE AND USAGE WAS EVIDENT IN THE PHOTOS. SIGNS OF FURTHER DAMAGES, EXCESSIVE FORCES, IMPROPER MANUFACTURING, TAMPERING AND/OR THIRD-PARTY REPAIR, COULD NOT BE CONFIRMED WITHOUT FURTHER REVIEW OF THE PHYSICAL SAMPLE. BASED ON THE PROVIDED INFORMATION AND PHOTOS THE SAMPLE MAY HAVE REACHED ITS END OF LIFE, OR MAY HAVE SUCCUMBED TO THE EXCESSIVE FORCES PLACED ON IT OVER ITS 20+ YEARS OF REPEATED USAGE, CLEANING, AND HANDLING. FURTHER INVESTIGATIONS COULD NOT BE PERFORMED TO CONFIRM THE SUSPECTED ROOT CAUSES. NO OTHER APPARENT ISSUES OR NON-CONFORMANCES WERE NOTED AND NO ADDITIONAL INFORMATION COULD BE EXTRACTED FROM THE PROVIDED IMAGES. WITHOUT A PHYSICAL SAMPLE AVAILABLE TO DETERMINE A MORE PRECISE ROOT CAUSE THE DEVICE WAS FOUND TO HAVE EXCEEDED ITS LIFE CYCLE AND WAS FOUND TO BE OUTSIDE OF WARRANTY COVERAGE. H3 OTHER TEXT : DEVICE WAS NOT RETURNED FOR EVALUATION. A PHOTO OF THE DEVICE WAS PROVIDED INSTEAD.
