Investigation ¿ evaluation an issue was reported with a wire guide from a femoral artery pressure monitoring set (rpn:(b)(4), lot: 13330274).During a femoral puncture, the wire guide unraveled inside the catheter and had to be removed.Cook became aware of this event on (b)(6)2021 upon being notified by agility logistics.The patient reportedly experienced no adverse effects as a result of this incident.A review of complaint history, device history record (dhr), manufacturing instructions (mi), and quality control of the device was conducted during the investigation.The complaint device was not returned; therefore, no physical examinations could be performed.However, a photo of the wire guide was provided to cook.The photo depicted the wire guide to be unraveled and the safety wire to be protruding.Unknown biomatter is observed at the distal end, obscuring the distal solder.Cook has concluded that the device was manufactured to specification.Additionally, a document-based investigation evaluation was performed.A review of the device master record (dmr) concluded that sufficient inspection activities are in place to identify this failure mode prior to distribution.A review of the design history file (dhf) showed that this device is both safe and effective for its intended use.A review of the dhrs for the reported complaint device lot (13330274) and the related wire guide subassembly lot revealed no recorded nonconformances.A database search did not identify any other events associated with the reported device lot.Based on the available information, cook has concluded that there is no evidence suggesting nonconforming product exists either in house or in field.This device is not supplied with an instructions for use (ifu).Based on the information provided, no returned product, and the results of the investigation, a definitive root cause for this event has been traced to component failure unrelated to a deficiency in manufacturing/device design.It is possible that a sharp edge such as the needle tip or tortuous anatomy damaged the wire guide.However, this cannot be confirmed without additional information.The appropriate personnel have been notified.Cook will continue to monitor for similar complaints.Per the quality engineering risk assessment no further action is required.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.
