Manufacturer¿s ref.No.: (b)(4).Information regarding patient identifier, date of birth, age, gender, weight, race, ethnicity, and medical history were not provided.The name, phone and email address of the initial reporter are not available / reported.[conclusion]: the healthcare professional reported that the 5mm x 10cm deltapaq 10 cerecyte coil (cdf10051030 / s10533) failed to be resheathed after the attempt to try and change the coil during the procedure.The introducer split.Adequate and continuous flush was maintained through the concomitant excelsior® sl-10® microcatheter (stryker).There was no resistance at any time when the coil was being advanced through the microcatheter.There was no issue with the microcatheter.Prior to this issue, there were other coils that went through the same microcatheter.There was a one-to-one relationship between the coil and delivery system, and it was verified with fluoroscopy prior to coil repositioning.The microcatheter was not repositioned over the coil while the coil was deployed / partially deployed from the distal end of the microcatheter.The coil was not positioned at a relatively sharp angle to the microcatheter.The event also employed the use of a stent (unknown brand).There was no blood flow reduction / restriction due to the reported issue with the failed resheathing.There was no report of any patient adverse event or complication.The complaint product was returned for evaluation and analysis.The investigational finding is documented below.Investigation summary: the non-sterile 5mm x 10cm deltapaq 10 cerecyte coil was received contained in a pouch.Visual inspection was performed.The embolic coil was mechanically detached inside the introducer.No other anomaly / damage was observed during the visual inspection.The complaint product underwent a microscopic inspection.The embolic coil was in stretched condition and mechanically detached from the rest of the complaint device.A review of manufacturing documentation associated with this lot (s10533) presented no issues during the manufacturing or inspection processes related to the reported complaint.There were no non-conformances related to device manufacture or inspection.All product rejected during manufacturing was identified as scrap and properly accounted for.The complaint reported that the coil could not be resheathed; the reported issue could not be duplicated in the product analysis lab due to the condition of the embolic coil.It was mechanically detached and in stretched condition.The observed conditions of the embolic coil may be related to the customer reported issue.They also appeared to be a result of force that was exerted during the device handling.The exact cause and timing of this cannot be determined.But the resheathing failure issue is confirmed based on the observed conditions of the embolic coil.The split introducer was not confirmed as the introducer of the complaint device was in good condition.Coil stretching is a known potential issue associated with the use of this device.The ifu provides proper handling instructions for the device to prevent such issue from occurring.Stretching can occur during procedure handling where force may have been inadvertently applied.The stretched condition of the embolic coil was not originally reported with the complaint.The exact cause of the observed stretched condition could not be conclusively determined.The stretched condition of the coil may also be related to the state of the embolic coil observed mechanically detached.Based on the manufacturing documentation review, there is no indication that the event is related to the device manufacturing process.In addition, devices undergo 100% inspection at final assembly for the condition of the embolic coil.Thus, it is not likely that the coil that was received for evaluation left the manufacturing facility with the embolic coil mechanically detached and in a stretched condition.As part of the post market surveillance program, information from this complaint is trended for statistical signals and corrective / preventive action may be triggered at a later time.Since there was no evidence to suggest the event was related to a manufacturing or design issue, no corrective actions will be taken at this time.The manufacturer will submit a supplemental report if new facts arise which materially alter information submitted in a previous mdr report.Additional information will be submitted within 30 days of receipt.
