Event or Problem Description
The patient was undergoing a coil embolization procedure in the vertebral artery using penumbra smart coils (smart coils).During the procedure, the physician reported that the smart coil would not advance from its initial position within its introducer sheath.Therefore, the smart coil was not used in the procedure.The same issue then occurred with another smart coil.This smart coil was also not used in the procedure.The procedure was completed using smart coils and other coils.There was no report of an adverse effect to the patient.
Additional Manufacturer Narrative
Results: the pet lock was intact on the proximal end of the pusher assembly.The pusher assembly was kinked at approximately 128.0 cm and 137.0 cm from the proximal end.The pusher assembly mid-joint was retracted into the introducer sheath friction lock.The embolization coil was undamaged and intact with the pusher assembly.The pusher assembly outer diameter was unable to measure due to the pusher assembly kink.Conclusions: evaluation of the returned smart coil revealed that the pusher assembly mid-joint was retracted proximal to the introducer sheath friction lock.If the mid-joint become retracted through the friction lock, resistance will likely be experienced while advancing the device.Forcefully advancing the device against this resistance may have contributed to the kinks on the pusher assembly.During functional testing, the embolization coil was unable to advance within its introducer sheath due to the mid-joint was retracted proximal to the friction lock.After proper re-sheathed the device into its introducer sheath, the embolization coil was able to advance through its introducer sheath and a demonstration microcatheter with resistance due to the kinks on its pusher assembly.Evaluation of the returned smart coil revealed that the pusher assembly mid-joint was retracted into the introducer sheath friction lock.If the mid-joint become retracted into the friction lock, resistance will likely be experienced while advancing the device.Forcefully advancing the device against this resistance may have contributed to the kinks on the pusher assembly.During functional testing, the mid-joint was advanced through the friction lock with resistance.After the mid-joint was passed through the friction lock, the device was able to advance through its introducer sheath and a demonstration microcatheter with resistance due to the kinks on the pusher assembly.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.This report is associated with mfr report number: 3005168196-2019-02058.
