The patient was undergoing a coil embolization procedure in the gastroduodenal artery (gda) using ruby coil lps and a lantern delivery microcatheter (lantern).During the procedure, after advancing a ruby coil lp into the target location, the physician decided to reposition the lantern.Therefore, the ruby coil lp was removed out from the microcatheter.Subsequently, while retracing the coil back into the introducer sheath, the physician experienced resistance and, consequently, the ruby coil lp had detached from the pusher assembly.The physician then advanced a new ruby coil lp to the target location; however, the physician decided to remove the ruby coil lp to reposition the lantern.While retracting the ruby coil lp through the lantern, the physician experienced resistance and the ruby coil lp unintentionally detached inside the lantern.The procedure was completed using additional ruby coil lps and a new lantern.There was no report of an adverse effect to the patient.

Evaluation of the returned ruby coil lp confirmed that the embolization coil was detached.Further evaluation of the device revealed kinks on the pusher assembly this damage typically occurs due to advancement against resistance.Based on the reported complaint, the ruby lp was advanced through a lantern microcatheter.The lantern microcatheter inner diameter (id) is larger than intended for advancement of the ruby coil lp and likely caused the resistance experienced during the procedure.If the ruby coil lp is retracted against resistance, the embolization coil may detach.The detached embolization coil was not returned for evaluation.Penumbra coils are visually 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.H3 other text: placeholder.
