One guidewire and one introducer needle were returned for evaluation.Functional, gross visual, microscopic visual and tactile evaluations were performed.The investigation is unconfirmed for the guidewire stuck in introducer needle, as the guidewire was able to be readily passed through the needle and no damage to the needle bevel was observed.However, the investigation is confirmed for damaged/unraveled guidewire, as the wrapping wire was observed to unraveled, elongated and bent.Furthermore, the core wire was observed to be broken.Just proximal to unraveled portion of the guidewire, there is a substantial amount of tissue/blood residue on small region of the guidewire.This is consistent with retracting the guidewire through needle (i.E.Removing the guidewire before removing the introducer needle).The definitive root cause could not be determined based upon available information.
