One guideright guidewire was received for evaluation.The distal end of the guidewire was pulled to remove the guidewire from the catheter; resistance was noted due to a dried blood like substance (bls), however, the guidewire was able to be removed.There were multiple bends and dried bls throughout the guidewire.No fibrous material was noted.The guidewire outside diameter measurement was consistent with manufacturing specifications.No resistance or other functional anomalies were noted during guidewire insertion through a dilator from current inventory.The device was manufactured according to specifications as supported by the receiving inspection results.The cause of the reported guidewire insertion difficulty and ¿fibrous material entwined with the guidewire¿ remains unknown.
