Manufacturer Narrative

Investigation evaluation: the product said to be involved was returned in a bio bag.Provided with the return was an open pouch from the lot number provided in the report.The label matches the product returned.Photos from the customer show the device and its packaging, and the lot number seen in the photo matches the returned product label.A photo also shows the basket, and a wire is broken.Our photo and laboratory evaluation of the product said to be involved confirmed the report.The device was returned with the basket fully extended out of the catheter lumen.One of the wires on the basket had broken loose from the proximal end of the basket and was still attached at the distal end of the basket.The basket extended and retracted freely with no sign of resistance, though the wire that detached remained outside of the lumen.The basket wire was broken near the soldered joint, but there was no evidence of the wire being damaged by the buff process.No part of the device was missing.There was a white hair-like substance noted just proximal to the tip of the basket, and the distal end of the catheter is damaged.At the distal end, the catheter also had minor kinks.No other anomalies were detected.A meeting with production management and supervision was held on (b)(6) 2021 where the broken wire was examined.It was confirmed that the wire had not been damaged by the manufacturing process, and no part of the device was missing.The device history record for the lot number said to be involved was reviewed.A discrepancy or anomaly was not observed with the product that was released for distribution.Investigation conclusion: a definitive cause for this observation could not be determined because the actual use conditions could not be duplicated in the laboratory setting.Due to a variety of clinical conditions such as patient anatomy, endoscope position or progression of disease state, we could not reproduce the actual conditions of product usage during our laboratory analysis.This limits our ability to conclusively determine a cause.Prior to distribution, all memory hard wire baskets are subjected to a visual inspection and functional testing to ensure device integrity.A review of the device history record confirmed that the lot said to be involved met all manufacturing requirements prior to shipment.Corrective action: a review of the complaint history was conducted.The likelihood of occurrence is considered rare.Corrective action is not warranted at this time based on the quality engineering risk assessment.Quality assurance will continue to monitor for complaint trends and reassess the risk assessment results as post market feedback continues to become available.
