Event or Problem Description
Additional information was provided on 17jan2023.The description of the coil "crumbling" initially reported was clarified to be coil elongation.The catheter was flushed prior to the attempted coil deployment.The physician used another catheter and coil to complete the procedure.

Additional Manufacturer Narrative
Blank fields on this form indicate the information is unchanged, unknown, or unavailable.Investigation ¿ evaluation.A representative of national cheng kung university hospital (taiwan) informed cook on (b)(6) 2023 of an incident that occurred on (b)(6) 2023 involving a nester platinum embolization coil (rpn: mwce-35-14-12-nester; lot: 14478455).It was reported that when the user attempted to deploy the coil, resistance was felt and the coil only partially deployed.Upon removal of the catheter, the coil was found to be elongated.The catheter was reported to be flushed prior to attempted deployment.No additional procedures or adverse effects were reported for the patient.Another catheter and coil were used to complete the procedure.Reviews of the complaint history, device history record (dhr), instructions for use (ifu), and quality control procedures, as well as a visual inspection of the returned device, were conducted during the investigation.One product was returned in a used and damaged condition.A portion of the coil remained inside the catheter.The coil was difficult to advance and separated inside of the catheter.Additionally, a document-based investigation evaluation was performed.In response to this incident, cook completed a review of the product device master record (dmr) and concluded that sufficient inspection activities are in place to identify this failure mode prior to distribution.Cook also reviewed the device history record (dhr).The dhr for lot 14478455 recorded two possibly relevant non-conformances for incorrect curl diameter and incorrect curl spacing, however these steps are checked 100% and all nonconforming product has been scrapped.A database search for complaints on the reported lot found no additional complaints reported from the field.Cook also reviewed product labeling.The current instructions for use [t_ce_nec_rev4] packaged with the device contains the following in relation to the reported failure mode: "warnings: if difficulties occur when deploying the embolization coil, withdraw the wire guide, coil and angiographic catheter simultaneously as a unit.Precautions: prior to introduction of the embolization coil, flush the angiographic catheter with saline.How supplied: upon removal from package, inspect the product to ensure no damage has occurred." the information provided upon review of the dmr, dhr, and ifu does not indicate the device was manufactured out of specification.There is no evidence of nonconforming material in house or in the field.Based on the information provided, inspection of the returned device, and the results of the investigation, cook has concluded that component failure unrelated to manufacturing or design deficiencies contributed to this incident.It is possible that there was a spot in the catheter that was missed during flushing, allowing friction between the catheter and coil, however this cannot be definitively confirmed.The appropriate personnel have been notified.Cook will continue to monitor for similar complaints.Per the 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.
