It was reported that part of a cope mandril wire guide separated during a hemodialysis catheter placement.The fragment separated into the patient¿s right groin soft tissue.The patient underwent surgery which successfully removed the fragment.Cook became aware of this event upon being notified by the risk manager from st.Joseph hospital.The patient reportedly experienced no additional adverse effects as a result of this incident.A review of the complaint history, device history record, instructions for use (ifu), manufacturing instructions, quality control, and specifications of the device were conducted during the investigation.Additionally, a document-based investigation evaluation was performed.Sufficient inspection activities are in place to identify this failure mode prior to distribution.The device history record (dhr) was reviewed.The dhr of final lot showed one related nonconformance where one device was scrapped due to the weld not being caught.A database search revealed no other complaints from final lot at the time of investigation.All nonconforming devices were scrapped, and all remaining devices in the lot underwent quality control activities such as outer diameter gauging and tensile pull tests.Since these 100% inspection procedures are in place and no other complaints have originated from this lot, there is no evidence that nonconforming product exists in house or in the field.Cook also reviewed product labeling.A label is attached to this device and depicts a warning to not pull the distal spring coil portion of the wire guide through the needle tip.Product labeling warns that withdrawing the wire guide through a needle increases the risk of distal tip damage.Based on the reported information however, it cannot be confirmed whether or not the user performed this action.The wire guide may have been damaged when initially advanced through the needle, but this cannot be confirmed without additional information.Based on the information provided, no returned product and the results of the investigation, it was concluded that component failure unrelated to manufacturing or design deficiencies contributed to the failure.The appropriate personnel have been notified.Per the quality engineering risk assessment no further action is required.Cook will continue to monitor for similar complaints.This report is required by the fda under 21 cfr part 803 and is based on unconfirmed information submitted by others.Neither the submission of this report nor any statement contained herein is intended to be an admission that any cook device is defective or malfunctioned, that a death or serious injury occurred, nor that any cook device caused, contributed to, or is likely to cause or contribute to a death or serious injury if a malfunction occurred.
