The following fields were updated due to additional information: d.9.Device available for eval?: yes.D.9.Returned to manufacturer on: 14-jan-2022.H.6.Investigation: three samples were provided to our quality team for investigation.Through visual inspection, brown stains were observed confirming rust or corrosion stains on the packaging and needle guard.It can be seen with the naked eye that all three packages are broken, two on the paper side (cracked) and one on the film side.If the packaging is open or broken it is possible these needles have been wet in some part of the transport process or in storage.The stainless steel of the needles could be oxidized by chlorine.Further analysis was conducted, there is no evidence of any problem with the shipping and storage of these needles to determine the root cause of this corrosion.A review of the device history for lot 2003020 was performed and no deviations or nonconformities were identified during the manufacturing process that could have contributed to this problem.The product is visually and functionally inspected throughout the manufacturing process in accordance with the procedure, verifying that all critical dimensions are within specification and that there is no product damage or defects.All records have been reviewed and no problems were identified during the inspections of the reported lots.Based on the information available, we are unable to identify a definitive root cause at this time.
