Manufacturer Narrative

Problem code (b)(4) for the reportable issue of bands failed to deploy.Investigation results: only the ligator head was returned for analysis and the other components were not returned.A visual examination of the component found five bands present with some bands were moved out of their positions.It was also noticed that the ligator teeth were bent.The suture was broken, likely to separate the device from the scope.Based on the evaluation of the returned ligator head, these failures are likely due to anatomical or procedural factors encountered during the procedure which limited the performance of the device.It is most likely that the ligator head teeth were damaged due to handling and manipulation of the device during the procedure.Once the ligator head teeth are damaged, the suture can be detached from its position on the ligator head and this condition could have impacted the bands deployment activity which could have contributed with the reported issues.Also, it is likely that the suture was broken to separate the device from the scope and this condition is not considered as an issue of the device.This failure is likely due to factors or conditions related to procedure during the use of the device that could have affected its performance and its intended purpose.Therefore, the most probable root cause is adverse event related to procedure.A review of the device history record (dhr) was performed and confirmed that this device met all material, assembly and performance specifications.
