Patient identifier: no patient involvement.Age & date of birth: no patient involvement.Patient sex: no patient involvement.Weight: no patient involvement.Ethnicity: no patient involvement.Race: no patient involvement.Operator of device: staff.Implanted date: no patient involvement.Explanted date: no patient involvement.Initial reporter occupation -manager / vet tech.The root cause of the complaint could not be identified at this time.The received actual sample was confirmed to have rust on the cannula body.Based on our checking, the defect could not have originated on our process, thus, this issue was communicated with the supplier.Based on our records the involved needle lot 200818fn has undergone product confirmation for black fm on cannula due to the replacement of the cannula rubber hold at the bonding station.No defect was noted (0/15,116 pieces) and these are confirmed not related to any rust like foreign matter.Retention samples of the affected lots supplied with the involved cannula were visually inspected wherein no similar defects or any anomalies that could lead to the complaint were observed.Also, the monitoring record of the temperature and humidity showed no abnormalities during the staging of the affected products that could lead to the formation of rust on the product.We have weekly machine maintenance cleaning to ensure that our needle assembly machines are consistently in good running condition and free from damage and contaminants.Moreover, in-process visual inspection is conducted during needle assembly and qc conducts outgoing visual inspection prior to shipment to confirm the condition of our products.The investigation for this nonconformity is still ongoing.(b)(4).
