Event Description

The patient was undergoing a coil embolization procedure to treat a pulmonary arteriovenous malformation (avm) using ruby coils.During the procedure, the physician successfully placed seventeen ruby coils in the avm using a lantern delivery microcatheter (lantern).While advancing the eighteenth ruby coil through the lantern, the physician experienced resistance.The physician continued to advance the ruby coil against resistance, and consequently, the pusher assembly of the ruby coil broke and the ruby coil unintentionally detached within the lantern.Therefore, the lantern containing the detached ruby coil was removed and the ruby coil was flushed out.The procedure was completed using the same lantern and additional ruby coils.There was no report of an adverse effect to the patient.

Manufacturer Narrative

Results: the pet lock was intact on the proximal end of the pusher assembly.The pusher assembly was fractured approximately 33.5 cm from the proximal end.Conclusions: evaluation of the returned ruby coil confirmed a fractured pusher assembly and detached embolization coil.If the device is forcefully advanced against resistance, damage such as a kink may occur.If a kinked device is further manipulated, the kink may worsen to a fracture.If the pusher assembly fractures, the pull wire will likely retract out of the pusher assembly distal detachment tip (ddt).If this occurs, the proximal constraint sphere will release from the ddt and allow the embolization coil to detach.The lantern was used to complete the procedure; therefore, the root cause of the resistance could not be determined.The embolization coil was not returned for evaluation.Evaluation of the returned lantern revealed an ovalization on the distal tip.The lantern was used to complete the procedure; therefore, the ovalization was likely incidental to the reported complaint and may have occurred post procedure.Penumbra coils and catheters 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.
