This follow-up report is being submitted to relay additional information.Visual examination of both provided pictures and returned product identified an implant blister damaged on one corner.Indeed, there are cracks on the plastic.No signs of damage to the box to cause the broken blister has been found.Pictures have been provided to the packaging department, hereafter their analysis: the blister pack appears to have suffered a shock: one area is fractured but not deformed.The packing carton does appear to be intact, only the blister pack is affected.The seal does not appear to be damaged, and the foams are still present.It seems unlikely that the shock was caused by an external impact during transport, in the original box.Insofar as the foams are present, the risk of the packaged part moving and causing the shock is low.The defect is probably the result of a direct impact on the blister pack (fall, contact with a sharp object, etc.).A review of the device manufacturing records confirmed no abnormalities or deviations that could be related to the reported event.With the available information, a definitive root cause could not be determined.
