Manufacturer¿s ref.No: (b)(4).Information regarding patient identifier, date of birth, age, gender, weight, race, ethnicity, and medical history were not provided.Procode is krd/hcg.[conclusion]: the healthcare professional reported that during the cerebral aneurysm coil embolization procedure, the 4mm x 7.5cm micrusframe 10 coil (mfr100407 / l16348) got stuck in the concomitant microcatheter and would advance any further.It was reported that the coil was prepped correctly and upon removal, the sales representative noticed that the distal end of the delivery wire or device positioning unit (dpu) that is proximal to the actual coil was kinked.The green part of the delivery system was not up against the hub.Another 4mm x 7.5cm micrusframe 10 coil was used and it got stuck as well, but the green part of the delivery system was relocated back up next to the connector hub and it was able to be completely pushed out and delivered into the aneurysm and deployed successfully.The procedure was successfully completed without any patient complication or procedural delay.The complaint device was returned for evaluation and analysis.The investigational finding is documented below.Investigation summary: the non-sterile 4mm x 7.5cm micrusframe 10 coil was returned; it was received contained in a pouch.Visual inspection was performed.The coil introducer was observed kinked and partially zipped.The device position unit (dpu) was kinked near the distal section.A microscopic inspection was performed.The embolic coil was observed kinked and there were some residues of dried blood observed.No other damages were observed during the microscopic inspection.A review of manufacturing documentation associated with this lot (l16348) presented no issues during the manufacturing or inspection processes related to the reported complaint.There were no nonconformances related to device manufacture or inspection.All product rejected during manufacturing was identified as scrap and properly accounted for.The complaint documented that during the procedure, the 4mm x 7.5cm micrusframe 10 coil got stuck in the concomitant microcatheter and would not advance further was not confirmed through functional evaluation; the embolic coil could not move inside the introducer due to the introducer being kinked.The embolic coil and the dpu were both observed to have kinked areas.The reported issue that the dpu was kinked in the distal area is confirmed through the visual inspection performed on the returned device.This observation is consistent with the photo of the complaint device that was provided by the sales representative.The kinked condition observed on the returned embolic coil was not originally reported with the complaint.Coil kinking is a known potential issue associated with the use of the device.The instruction for use provides proper handling instructions for the device to prevent issues such as kink from occurring.The exact cause of the observed kinked condition could not be conclusively determined; however, it may have been the result of inadvertent force that may have been applied during the attempt to advance the coil when it became stuck in the concomitant microcatheter as reported in the complaint.There were some residues of dried blood observed during the microscopic inspection of the embolic coil, an indication that adequate and continuous flush may not have been maintained through the microcatheter during the procedure which may have caused the coil to become stuck in the microcatheter.Based on the review of the manufacturing documentation, 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 4mm x 7.5cm micrusframe 10 coil left the manufacturing facility with the in the observed kinked 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.
