The lot met all release criteria.Device history records were reviewed and no deviations/issues were identified or associated with this problem in regards to product materials or during manufacturing, packaging or qc inspection process.All necessary inspections were performed throughout all manufacturing, packaging and inspection activities and for raw material utilized in the manufacture of this lot in regards to the described problem.One introducer needle and one guidewire were returned for evaluation.Gross visual and microscopic visual evaluations were performed.The investigation is inconclusive for improper guidewire/needle, as the guidewire and needle were received separated from each other and the conditions at the time of the reported event could not be reproduced in the lab.However, the investigation is confirmed for elongated/unraveled guidewire, as unraveling was observed near the distal end of the guidewire.Residue was observed throughout the needle and the guidewire.The definitive root cause could not be determined based upon available information.Blood/tissue residue in the needle and/or on the guidewire, and/or retracting the guidewire through the needle may have contributed to the observed guidewire unraveling.Alternatively, the guidewire unraveling may have contributed to the reported event.However, the origin and time of the observed unraveling is unknown.It is unknown if procedural issues contributed to the reported event.The device is labeled for single use.
