A device history record review for the reported lot shows that the order was built to specification.One wet, used fluidics management system was returned for this complaint.The sample was visually inspected and surgical debris and viscoelastic substance was found in the aspiration line.It was also noted that the drain bag was detached from the cassette cover due to saturation.The surgical debris was attempted to be purged from the aspiration line; however, the substance was too solid to purge.The aspiration tubing was cut one inch from the cassette insertion and the aspiration line was replaced with one from the lab stock.The sample was functionally tested with the lab stock aspiration line and passed testing.The root cause of the occluded surgical debris and viscoelastic in the aspiration line is unknown.One potential root cause is excessive use as the sample was returned used.When the occluded aspiration line was replaced with one from the lab stock, the sample met specifications.In future testing, even if the tubing is occluded with surgical debris, the sample will be functionally tested to attempt to replicate the customer's complaint on the console.(b)(4).
