The patient was undergoing a coil embolization procedure to treat a ruptured aneurysm in the right internal carotid artery (ica) using penumbra smart coils (smart coils).During the procedure, four smart coils would not advance at all within their introducer sheaths; therefore, they were removed.The procedure was completed using additional smart coils.There was no report of an adverse effect to the patient.

Results: the pet lock was intact on the proximal end of the pusher assembly.The pusher assembly was kinked approximately 21.5, 23.0, 135.0, 137.0, 151.0 and 153.0 cm from the proximal end.The pusher assembly mid-joint was retracted through the introducer sheath friction lock.The embolization coil was undamaged and intact with the pusher assembly.Conclusions: evaluation of the first returned smart coil revealed that the pusher assembly mid-joint was retracted through the introducer sheath friction lock.If this occurs, resistance may be experienced during advancement.During functional testing, the pusher assembly mid-joint was advanced through the introducer sheath friction lock with resistance.The smart coil was then advanced through its introducer sheath without an issue.Evaluation of the second returned smart coil revealed that the pusher assembly mid-joint was retracted through the introducer sheath friction lock.If this occurs, resistance may be experienced during advancement.During functional testing, the pusher assembly mid-joint was advanced through the introducer sheath friction lock with resistance.The smart coil was then advanced through its introducer sheath without an issue.Evaluation of the third returned smart coil revealed that the pusher assembly mid-joint was retracted through the introducer sheath friction lock.If this occurs, resistance may be experienced during advancement.Further evaluation revealed pusher assembly kinks throughout its length.This damage was likely incidental to the reported complaint and was likely occurred during packaging for returned to penumbra.During functional testing, the pusher assembly mid-joint was advanced through the introducer sheath friction lock with resistance.The smart coil was then advanced through its introducer sheath with resistance due to the pusher assembly kinks.Evaluation of the fourth returned smart coil revealed that the pusher assembly mid-joint was retracted through the introducer sheath friction lock.If this occurs, resistance may be experienced during advancement.During functional testing, the pusher assembly mid-joint was advanced through the introducer sheath friction lock with resistance.The smart coil was then advanced through its introducer sheath without an issue.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.This report is associated with mfr report numbers: 3005168196-2020-02022, 3005168196-2020-02023, 3005168196-2020-02025.H3 other text : placeholder.
