Investigation ¿ evaluation: a review of documentation, complaint history, device history record, manufacturing instructions, visual inspection, specification, instructions for use (ifu) and quality control data was conducted during the investigation.The device set is supplied with two different wire guides, one short wire for gaining access and a longer marked wire for guiding the catheter into the target vessel.The customer did not specify which wire contributed to this complaint.An evaluation of the ifu was performed.The ifu states the intended use, warnings, precautions, product recommendations, and instructions for proper use.Wire guide was manufactured according to specified dimensions and the bill of materials.The wire guide was inspected per quality control procedures, including a torque test, verification of solder joints, and inspection of the distal tip.The device history record was reviewed and there were no non-conformances found to be related to the failure mode in this event.To date, a search of complaint records revealed this complaint to be the only reported complaint associated with the complaint lot number.Two wires were returned for investigation.The associated catheter was also returned and has been evaluated in separate complaint record (b)(4).During the investigation, it was observed that there were multiple kinks located towards the distal end on the coiled section.The transition zones between mandril and coiled wire were smooth.The tip weld is intact.No section of the wire is missing or broken.The wire dimensions were found to be in specification.The access wire (shorter length) was also returned used and damaged.There are multiple kinks located towards the distal end on the coiled section.The transition zones between mandril and coiled wire were smooth.The tip weld is intact.No section of the wire is missing or broken.The wire dimensions were found to be in specification.Based on the investigation and the reported tortuous anatomy, it is probable that kinking was caused by the patient anatomy.The reported 'soft tip was broken' cannot be confirmed as neither wire guide appears broken or separated in any way.The initial report that the catheter could not be introduced over the wire could be a result of the distal end kinking.We will notify the appropriate personnel and continue to monitor for similar complaints.Per the risk assessment no further action is required.
