The hith kit (inshith) was returned for evaluation: device history record (dhr) review - the dhr was reviewed, and no anomalies were found during the manufacturing and packaging process that could be related to the reported condition.Failure analysis - investigation was performed using photographs which were taken prior to receipt of the returned product, as the physical sample was not required to complete the evaluation.The photographs revealed the white box of a cranial access kit and the cardboard box the carrier supplied to be contaminated with some form of oil.The oil has not penetrated through the foam into the sterile pouch inside the white cardboard box, but it is an unacceptable cosmetic defect that would erode the customer's confidence in the cleanliness and safety of the product.The carrier supplied their house brand cardboard box to repackage the material, a style of box that is not used anywhere in our facility, and neither is there record of any oil spill affecting the product during the time of manufacture and shipping.Root cause - the product was damaged after leaving this site.The carrier damaged and repackaged the product instead of reporting the damage.No further investigation is required based on the acceptability of risk and no adverse trends identified.This will be monitored and trended going forward.
