Block b3: date of event: date of event was approximated to (b)(6) 2019 as no event date was reported.Block h6: problem code 2610 for the reportable issue of bands failed to deploy.Block h10: investigation results received one speedband superview super 7 with the ligator head for analysis.It was noticed that the trip wire was completely rolled in the handle assembly slot when received.A visual examination of the ligator head found all seven bands present, which were moved out of their original positions.It was also noticed that the ligator teeth were bent.Additionally, the suture was observed to be broken with one section was attached to the ligator head, while the other section was attached to the trip wire loop.A functional evaluation was performed by rotating the handle knob 180 degrees, an audible click was heard and indents were felt.No visible issue was noted with the handle assembly.There was evidence that the suture was broken in order to separate the device from the scope.This condition is not considered as an issue of the device.Based on the evaluation of the returned complaint device, 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 and could have contributed to 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.
