Event or Problem Description
The patient was undergoing a coil embolization procedure in the renal artery using a lantern delivery microcatheter (lantern) and ruby coils.During the procedure, while advancing a ruby coil through the lantern, the physician experienced resistance and subsequently, the ruby coil became stuck at the distal end of the lantern.The physician attempted to push the ruby coil through the lantern but was unable to get the ruby coil to move.The physician then attempted flush the ruby coil out of the lantern and into the aneurysm; however, the ruby coil remained stuck in the same location.Therefore, the ruby coil and lantern were removed from the patient.The procedure was completed using a new lantern and a new ruby coil.There was no report of an adverse effect to the patient.
Additional Manufacturer Narrative
Results: the lantern was ovalized from approximately 133.5 ¿ 134.5 cm from the hub.Conclusions: evaluation of the returned lantern revealed an ovalization on the distal tip.If the device is gripped or pinched during use, damage such as an ovalization may occur.During functional testing, a demonstration mandrel was unable to advance through the lantern due to the ovalization.The ovalization likely contributed to the resistance experienced during the procedure and during the functional testing.Evaluation of the returned ruby coil revealed a kinked and fractured pusher assembly, a detached embolization coil and offset coil winds on the proximal end of the embolization coil.If the ruby coil is forcefully advanced against resistance, damage such as offset coil winds and a kinked pusher assembly may occur.Further manipulation of a kinked pusher assembly may result in a fracture which may cause the embolization coil to detach.Further evaluation revealed additional pusher assembly kinks.These kinks were likely incidental to the reported complaint.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.This report is associated with mfr report number: 3005168196-2019-02028.
