Manufacturer Narrative

Investigation evaluation: the product said to be involved was returned in a white plastic bag.Provided with the return was an open box/tray from the lot number provided in the report.The label matches the product returned.A picture was also provided and reviewed.The picture provided shows the device inside the tray.Our laboratory evaluation of the product said to be involved confirmed the report.The two-way handle, loading catheter, irrigation adapter, and the trigger cord attached to the barrel with 10 bands were included in the return.The two-way handle was returned in the firing position, with handle manipulation it would rotate in the counterclockwise direction and would not rotate in the clockwise direction.The current functionality of the handle would be rotation in the clockwise direction while in the firing position.The device was returned to the supplier for further evaluation.The supplier provided the following information: "during disassembly of the returned sample, it was discovered that the bearing placement was in the part incorrectly (backwards)." 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: the functional verification of the returned handle confirmed the report.The handle would only rotate in the counterclockwise direction in the firing position which is not the correct rotational direction.The handle supplier's investigation determined the handle was assembled incorrectly during manufacturing.The supplier implemented a process change which addresses the incorrect assembly and increased the verification level for correct rotation.Prior to distribution, all 10 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: a review of the complaint history was conducted and this represents an isolated occurrence.The likelihood of occurrence is considered remote.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.
