Additional Manufacturer Narrative
Product complaint # (b)(4).The purpose of this mdr submission is to report the findings of the device investigation.Based on the product analysis, the embolic coil is kinked.The findings meet us regulatory reporting criteria.Information regarding patient weight, height, medical history, race, and ethnicity was not reported.Section d2b ¿ procode: krd/hcg.Section e1.Initial reporter phone: (b)(6).A non-sterile galaxy g3 mini 1mm x 1cm was received contained in the decontamination pouch.Upon receiving the device, visual inspection was performed, and it was noted that the coil was returned inside the introducer.Under magnification, the embolic coil was found to be kinked.However, remained attached to the resistance heating (rh).No other damages were noted in the device.The issue documented a coil being impeded in the proximal section of the microcatheter was confirmed based on the appearance of the returned device.The kinking observed in the coil was not originally reported in the complaint however it could be the result of the impeded condition experienced during the procedure.Kinking can occur during procedure handling where force may have been inadvertently applied.According to the risk documentation, friction and difficulty to advance are potential issues that can occur during microcoil placement due to continuous saline flush not being established, which can result in coil kinking.Coil kinking is a known potential issue associated with the use of this device.The instructions for use (ifu) provide proper handling instructions for the device to prevent such issues from occurring.There is no indication that the issue reported is a result of a defect inherently related to the device.A manufacturing record evaluation was performed, and no non-conformances related to the reported complaint condition were identified.As part of j&j medtech quality process, all devices are manufactured, inspected, and released to approved specifications.Therefore, no capa activity is required.It should be noted that multiple factors could cause product failure.The instructions for use (ifu) contain the following precautions: ¿ 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.If unusual friction is still noticed during advancement or retraction of the microcoil system, verify flush lines are open and properly pressurized.Then slowly withdraw the entire microcoil system and examine for damage.Replace it with a new microcoil system.If friction still exists, withdraw and examine the delivery catheter system.If repositioning of the microcoil is necessary, carefully observe the motion of the microcoil in respect to the dpu wire while retracting the microcoil under fluoroscopy.If the microcoil movement is not one-to-one with the dpu wire, or if repositioning is difficult, the microcoil may have become stretched and could possibly break.Gently remove and discard the microcoil system.As part of the post market surveillance program, information from this complaint is trended to identify statistical signals for consideration of further correction action.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.
Event or Problem Description
As reported by the field, during a coil embolization of the anterior cerebral artery (aca), a galaxy g3 mini 1mm x 3cm was impeded in proximal of a non j&j microcatheter (mc) and could not advance any more.The doctor only retracted the coil alone and switched to a new one to complete the surgery.The microcatheter was not replaced.There was no patient injury reported.Additional event information received on 23-jan-2025 indicated that the event did not result in any undue procedural delay that could be considered clinically significant.There were no relevant anatomical information including vessel characteristics.The device did not appear damaged at any time.Nothing was noted to be obstructing the microcatheter.A continuous flush was maintained.Based on the product analysis of the device received, the embolic coil is kinked.
