(b)(4).Investigation summary: one photo was provided to our quality team for investigation.The final product for lot ta12092 is assembled and packaged at a supplier site.We notified the supplier of the reported issue and provided the photo for evaluation.Upon visually inspecting the photo that was received, a drop of liquid is observed outside the set, near the y-site.There is no evidence of damage or a break at this connection.Retained samples were used for additional evaluation, there were no visual defects noted and all product was manufactured according to specification.It was thought that excessive force by the operator when connecting the connector piece to the y-site could have been a potential cause for this incident.All testing was reviewed for the reported lot, including leakage, torque, and inspection results with no issues identified related to the reported malfunction.Without the physical sample we cannot verify any damage to the product or determine where the liquid originated therefore we were not able to identify a definitive root cause related to the manufacturing process at this time.Complaints for this device and defect will continue to be monitored by our quality team for signs of emerging trends.
