Block h6: device code 2610 for the reportable issue of bands failed to deploy.Block h10: investigation results the returned speedband superview super 7 device and the ligator head were analyzed.A visual evaluation noted that the tripwire was mechanically cut and was outside of the handle and it was noticed that the proximal loop was not returned.The handle assembly slot where the tripwire was inserted and secured showed drag marks, indicating that the device was used.It was noted that the distal loop was attached to the suture and was connected to the ligator head.It was possible to observe that the ligator head found six bands attached; however, five bands were moved out of their original positions and one band was not returned.It was noted that some of the ligator head teeth were bent.Additionally, the suture hole was in good condition and no damages were observed.A functional evaluation was not performed due to the tripwire was cut.No visible issue was noted with the handle assembly.No other issues with the device were noted.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 generated the bands to moved out of their original positions, impacting the bands deployment activity and could have contributed to the reported issues.There was evidence that the trip wire was cut in order to remove the device from the scope.This condition is not considered as an issue of the device.The reported event was confirmed.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.
