Block h6: problem code 2610 for the reportable issue of bands failed to deploy.Problem code 2949 for the reportable issue of bands falling of varix.Block h10: investigation results a speedband superview super 7 was returned with the ligator head and suture for analysis.A visual examination of the ligator head found three bands present which were moved out of its original position.It was also noticed that the ligator teeth were bent.No other issue was noted.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.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.
