A review of the device history record (dhr) was completed for lot 19h15763x.During the production of this lot a non-conformance investigation was opened to determine the root cause of particulate matter observed in the fluid pathway; however, this particulate matter was identified as plastic shavings caused by build up in the aidlin system which transports the barrels from the molding process to the assembly process.In the assembly process blow off vacuums are in place to remove particulate such as hair and a review of shift notes and work orders did not find any issues with the blow off vacuums during or around the time of production of this lot.The dhr review showed that all acceptance criteria inspections per established sampling levels were within acceptable limits during the production process.The customer provided photographic evidence of the alleged condition of particulate matter (strand of hair) inside the fluid path of the syringe.The physical device was discarded.The photos were reviewed and a strand of hair was observed; however, it was difficult to confirm that pm was inside the fluid pathway.For the purposes of this investigation it was assumed that the hair was inside the fluid path as alleged.Based on the information available and the investigation findings, the most probable root cause of the event was failure of the gowning procedure required by all personal entering the controlled manufacturing procedure.The investigation was not able to determine if it was a failure of personal to follow the gowning procedure or a failure of the gowning material.The process and procedures in place to prevent this condition were reviewed and determined to be adequate at this time.No further actions will be taken at this time.This complaint will be used for tracking and trending purposes.
