Block h6: device code 1069 captures the reportable event of tripwire broken.Block h10: investigation results: the returned speedband superview super 7 device was analyzed.It was also noted that the trip wire was not broken (as was reported), instead it was observed that the suture thread was broken.The trip wire was not secured and the slack was not taken up correctly.A functional evaluation revealed resistance to rotation, due to the tension on the trip wire.No other issues with the device were noted.A labeling review was performed and from the information available, this device was not used per the instructions for use (ifu)/product label: the visual assessment identified that the trip wire was not secured in the handle assembly, nor did the handle have evidence that the trip wire was previously secured.Not securing the trip wire in the handle slot could have caused the trip wire to slip through the handle assembly during deployment.The slack was not taken up correctly which provided extra tension on the device and may have led to the suture break.Taking all available information into consideration, the most probable root cause of this event is failure to follow instructions.A review of the device history record (dhr) confirmed that this device met all material, assembly, and performance specifications.
