Additional Manufacturer Narrative
Product complaint # (b)(4).Updated sections on this med watch: b4, d1, d9, g3, g6, h2, h3, h6 and h11.Corrected: d1.Brand name: galaxy g3.Complaint conclusion: as reported by the field, during a coil embolization, the physician just started to fill the aneurysm with a galaxy g3 xsft 3mm x 6cm coil (glx120306, 30772779), it was found that the filling site was unsatisfactory.Therefore, the physician retracted the coil, but the coil was unraveled/stretched.The physician retracted the coil out of the patient and switched a new one to complete the surgery.The unspecified microcatheter (mc) was not replaced.There was no patient injury reported.Additional event information received on 23-sep-2024 indicated that there was no coil positioning difficulty.No excessive force was used with the device.A non-sterile galaxy g3 xsft 3mm x 6cm was received contained in the decontamination pouch.Upon receiving the device, a visual inspection was performed, and it was noted that the coil was returned tangled with the delivery system.Under magnification, the embolic coil was found to be severely stretched and it was noted that as a result of the stretching the internal blue fiber was exposed.However, this remains attached to the resistance heating (rh), which was noted to be not softened.No other damages were noted in the device.The issue documented a coil that was stretched was confirmed based on the appearance of the returned device.Stretching can occur during procedure handling where force may have been inadvertently applied.According to the risk documentation, friction is a potential issue that can occur during microcoil re-sheathing due an rhv not being adequately loosened or the introducer sheath being too tight within rhv, which can result in coil stretching.Coil stretching 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.As part of cerenovus quality process, all devices are manufactured, inspected, and released to approved specifications.Therefore, no capa activity is required.A manufacturing record evaluation was performed for the finished device 30772779 number, and no non-conformances related to the malfunction were identified.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.A supplemental report will be submitted if new facts arise which materially alter information submitted in a previous mdr report.
