The returned cassette was evaluated.A review of the lot history revealed no nonconformities that could have contributed to the reported complaint.The device underwent visual inspection.A customer-provided image showed a leak in cassette; however, as received, no damage or anomalies were observed.Functional testing was performed, during which a leak was detected from corner 2 of the cassette bag when fully filled, confirming the reported leakage issue.The probable cause of the leakage is likely unintentional damage to the bag seam during closure of the side panel in the compounding process.
