Additional Manufacturer Narrative
Investigation evaluation: the product said to be involved was returned in a biohazard bag with an open box and tray from the lot number provided in the report.The label matches the product returned.All device components were included in the return.Photos were provided and reviewed.The first photo shows the tray and bands can be seen deployed loose in the tray.The second photo shows the box label and it matches that in the report.Our laboratory evaluation of the product said to be involved confirmed the report.Only 2 bands remained on the barrel as received.Four bands returned loose in the tray.The band remaining on the barrel had slightly moved along the barrel as in premature deployment.A visual examination of the device was performed.The trigger cord was examined and all twelve deployment beads were present.The beads could not be verified for correct location due to the trigger cord still being attached to the barrel.The beads were examined using magnification and found to be correctly filled and had no evidence of excess flash.The trigger cord was intact and not broken.The length of the trigger cord was measured at 143.4 cm between the knots which is within the 56" +2"/-1" (139.7-147.32 cm) tolerance.An evaluation of the handle wheel movement was performed, and the wheel functioned as intended.A product-specific discrepancy that could have caused or contributed to this observation was not observed during our laboratory analysis.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: our evaluation of the returned device confirmed the report.A definitive cause for this observation could not be determined because the actual prior to use product preparation and handling conditions could not be duplicated in the laboratory setting.This limits our ability to conclusively determine a cause.Premature band deployment can occur if the device experiences excessive pressure during general handling or shipment.Prior to distribution, all 6 shooter saeed multi-band ligators are subjected to a visual inspection 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: based on the quality engineering risk assessment no corrective action is warranted at this time.A review of the complaint history was conducted.Based on this review, the likelihood of this type of report is rare.Quality assurance will continue to monitor for complaint trends.
