Result: the pusher assembly was kinked approximately 18.0 cm from the ddt, and kinked approximately 18.0 cm from the proximal end.The introducer sheath was kinked approximately 15.0 and 30.0 cm from the proximal end.The coil was stuck inside the introducer sheath.The od of the ddt was measured and found to be within product specifications.Conclusion: the complaint has been evaluated.The complaint indicated that during the procedure, the coils could not be advanced into a microcatheter.The coils were removed and the patient was not affected.Evaluation of the returned devices revealed in the first ruby coil, the pusher assembly was fractured and kinked, and the coil was kinked.Further evaluation revealed in the second ruby coil, the pusher assembly and introducer sheath were kinked.The type of damage found on both ruby coils typically occurs due to attempting to advance the device past resistance.In both ruby coils, the od of the ddt was measured within specification.The microcatheter used in the case was not returned and the model of the microcatheter was not reported in the complaint and, therefore, the root cause of the inability to advance the coils into the microcatheter cannot be determined.These devices are 100% functionally tested and visually inspected during process inspection.The manufacturing records for this lot were reviewed and did not reveal any outstanding discrepancies, design, or quality concerns.
