Block a1: it was reported that the patient identifier is (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 partially rolled in the handle assembly slot when received.A visual examination of the ligator head found five bands present which were moved out of their original positions with one band was caught under the other band.It was also noticed that the ligator teeth were bent.Additionally, the suture was observed to be intact.Media examination was performed and the attached video provided by the customer showed the device placed on the scope; the handle was rotated, then a band was moved out, but the device failed to deploy elastic bands, confirming the reported issue.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, moving bands without being deployed, and contributing to the reported issues.Based on the information available and the analysis performed, it was concluded that the investigation conclusion code of this event is adverse event related to procedure, since adverse event occurred during the procedure and the device had no influence on event.A review of the device history record (dhr) was performed and confirmed that this device met all material, assembly and performance specifications.
