Manufacturer¿s ref.No: (b)(4).Information regarding patient identifier, date of birth, age, gender, weight, race, and ethnicity were not provided.Procode is krd/hcg.The initial reporter phone: (b)(6).The initial reporter email address is not available / reported.Conclusion: the healthcare professional reported that during a cerebral coil embolization procedure of an unruptured aneurysm on the left internal carotid-posterior communicating artery (icpc), an approach was made from the right femoral artery with a 6fr axcelguide¿ guiding sheath(medikit co, ltd), and an approach to the left common carotid artery (cca).From there, a dd6 intermediate catheter (medikit co, ltd) was raised up to the petrous and a concomitant phenom¿ 17 microcatheter (medtronic) was delivered to the target lesion on the icpc.Embolization was initiated by placing a shoryu sr 4-10 balloon catheter (kaneka medix) on the neck.After the implantation of some competitor coils, the 1.00mm x 4.00cm galaxy g3 mini coil (glm910040 / 30392730) was chosen for additional embolization.The physician tried to introduce the complaint device into the microcatheter, but it was not able to be advanced further.The complaint coil was removed from the patient¿s body without having to remove the concomitant microcatheter, an attempt was made to ¿extrude¿ the coil from the introducer, however, it did not come out from the tip of the introducer.It was reported that there was continuous flush maintained through the microcatheter.The complaint device did not appear damage.The introducer was flushed and the tip of the introducer was firmly installed into the hub of the concomitant microcatheter and locked with the rotating hemostasis valve (rhv) during the device advancement.The complaint coil was replaced with another the 1.00mm x 4.00cm galaxy g3 mini coil (glm910040) and there was no problem with the replacement coil.The procedure resumed.There was no report of any patient adverse event or complication.The complaint device was returned for evaluation and analysis.The investigational finding is documented below.Investigation summary: a non-sterile 1.00mm x 4.00cm galaxy g3 mini coil was received.Visual inspection was performed.It was noted that the core wire and the introducer were both in good condition.There were no evidence of damages observed on the device.Microscopic inspection was performed.Under magnification, it was observed that the embolic coil component was damaged inside the introducer.It is possible that this condition may have been the result of the advancement of the embolic coil inside the introducer and as a result, did not allow for the introduction of the complaint device into the hub of the concomitant microcatheter.Functional testing could not be performed due to the damaged condition of the embolic coil.The damage embolic coil cannot be advanced out nor retracted back in the introducer.The reported issue documented in the complaint was confirmed based on the observed condition of the embolic coil.However, the possible cause(s) and / or contributing factors of the observed damaged condition of the embolic coil were not conclusively determined.Additional information received indicated that there was no report that the device appeared damaged.A review of manufacturing documentation associated with this lot (30392730) 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.As part of the cerenovus quality process, all devices are manufactured, inspected, and released to approved specifications.It should be noted that product failure could be caused by multiple factors.The instructions for use (ifu) contains the following recommendations: do not fasten the rhv valve too tightly around the introducer sheath since excessive pressure may cause damage to the introducer sheath and/or the microcoil as it is advanced into the infusion microcatheter.Additionally, if the introducer tip and microcatheter hub are misaligned, damage may occur to the microcoil as it passes through this transition.If unusual friction is noticed during advancement or retraction of the microcoil system, verify the locking mechanism, or clear tab is unlocked and pulled out from the resheathing tool approximately 1 in (2-3 cm).If unusual friction is noticed during advancement or retraction of the microcoil system through the introducer, open the rhv main valve, and partially withdraw the distal end of the introducer to expose its tip within the rhv.Tighten the rhv main valve and flush the y-connector of the rhv with sterile saline and verify that fluid exits the slit in the clear portion of the introducer.After flushing, reinsert the introducer into the infusion catheter hub as described in ¿microcoil placement¿ section above.Coil damaged 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 as coil damage from occurring.The damaged condition observed on the embolic coil under magnification was not originally reported at the complaint initiation and may have been related to other factors; the exact cause cannot be conclusively determined.Based on the device history record review, there is no indication that the event is related to the device manufacturing process.Devices undergo 100% inspection at final assembly for the condition of the embolic coil.Thus, it is not likely that the 1.00mm x 4.00cm galaxy g3 mini coil left the manufacturing facility with the embolic coil in the damaged 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.Missing information from this report is identified as blank; this information was not provided in the reported event or available at the time of report submission.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.
