Visual, functional, and electrical analysis were performed on the returned device.The reported event of solid yellow light could be confirmed.Multiple bends/kinks and separation were noted on the proximal tube; however, the wire was still held together by the corewire.An electrical testing was performed, and an open circuit on the male connector area was observed during testing which could contribute to the reported issue.A review of the lot history record identified no manufacturing nonconformities issued to the reported lot that would have contributed to this event.Additionally, a review of the complaint history identified no indication of a lot specific product quality issue.The investigation determined that the reported solid yellow light was likely due to the noted separation.It was likely that an excessive force was used during preparation which may have caused bends/kinks resulting in the noted separation.The separation likely caused the open circuit which could trigger the reported issue during calibration.There is no indication of a product quality issue with respect to the design, manufacture, or labeling of the device.
