Follow up mdr for device evaluation/correction: based on investigation results, this complaint is no longer reportable.The involved device did not contribute to the reported failure, coring.Device evaluation it was reported that particles were observed inside the vial and iv bag during preparation.For investigation, one protector assembled onto a vial, one iv bag, one l connector, and a spike set not manufactured by bd were provided to our quality team.Inspection of the returned samples confirmed the presence of a gray particle in both the vial and the infusion bag.Visual assessment determined that the particle in the vial originated from the vial stopper, while the particle found in the iv bag was consistent with material from the iv bag stopper.During evaluation, it was observed that the protector needle penetrated the vial stopper at a raised area, resulting in fragmentation of the stopper.A small stopper piece was also found within the protector needle.Additionally, the iv bag stopper was noted to be significantly torn.No damage or defects were identified within our devices that could have contributed to this observation.Final products in this manufacturing line, for this reference are sampled and they are subjected to visual and functional inspections during the different manufacturing subprocesses according to procedures.A device history review was performed for protector lot 2501110, no deviations or non-conformances were identified during the manufacturing process that could have contributed to this observation.As a lot number for the lconnector was unavailable for this incident, a device history record review could not be completed.Coring of the rubber stopper may occur depending on stopper quality, design, or if a poor connection is made.Based on the investigation and sample evaluation, the vial stopper fragmentation was attributed to the protector needle piercing a raised portion of the stopper during assembly.Due to the extent of damage observed on the iv bag stopper, it was not possible to definitively determine which spike contributed to the observed particulate matter; therefore, a specific root cause could not be identified.No issues related to the injector were identified.
