Manufacturer Narrative

Isi received the permanent cautery hook instrument involved with this complaint and completed the device evaluation.Failure analysis confirmed the reported issue and found thermal damage at the weld joint of the yaw pulley once a side of the clevis ear was removed for further investigation.The silicone potting was noted to be compromised and conductor wire damage was noted near the weld location.The instrument failed an electrical continuity test.When the conductor wire was exercised on the distal end, it detached from the yaw pulley, which suggests that the wire broke at the weld location.It was noted that the silicone potting damage may have allowed for excess movement of the wire at the yaw pulley exit, which may have increased fatigue stress on the wire.No signs of user mishandling/misuse were noted.Based on the information provided at this time, this complaint is being reported because the permanent cautery hook instrument smoked and had conductor wire damage with no evidence or claim of user mishandling or misuse.
