Manufacturer Narrative

Block e1: facility name: (b)(6).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 crimp was present on the trip wire and the trip wire was secured in the handle assembly slot when received.A visual examination of the ligator head found seven bands present which were moved out of their original positions.It was also noticed that the ligator teeth were bent.The suture was not damaged and was attached to the ligator head.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.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 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.
