The patient was undergoing a coil embolization procedure in the internal iliac artery (iia) using a lantern delivery microcatheter (lantern), ruby coils, and a pod packing coil (pod pc).During the procedure, the physician successfully implanted three ruby coils in the target vessel using the lantern.It was reported that the lantern was flushed in between the coils.While advancing the pod pc through the lantern, the pod pc became stuck at the distal end of the lantern.Therefore, the lantern containing the pod pc was removed.On the back table, upon removing the pod pc from the lantern, the physician found that the pod pc had unintentionally detached and the pusher assembly was broken.The procedure was completed using a new pod pc and the same lantern.There was no report of an adverse effect to the patient.

Evaluation of the returned pod pc confirmed that the embolization coil was detached from the pusher assembly but could not confirm the reported fractured pusher assembly.Evaluation revealed that the sr component was fractured.This damage may occur if the device is retracted against resistance during use.It was reported that the coil became stuck during advancement at the distal end of the parent microcatheter.The root cause of the coil becoming stuck could not be determined.This damage likely contributed to resistance during retraction.Further evaluation revealed pusher assembly kinks throughout its length.This damage was likely incidental to the reported complaint and may have occurred during packaging for return to penumbra.Penumbra coils are inspected during in-process inspection and during quality inspection after manufacturing.The manufacturing records for this lot were reviewed and did not reveal any outstanding discrepancies, design, or quality concerns.
