Event Description
|
The patient was undergoing a coil embolization procedure in the vein of galen using penumbra coils 400 (pc400s) and a px slim delivery microcatheter (px slim).During the procedure, the physician placed four pc400s in the vein using the px slim.While advancing the next pc400, the physician experienced resistance, and the friction lock on the introducer sheath broke; therefore, the pc400 was removed.It is unknown if the pc400 entered the px slim.The physician continued the procedure and placed another pc400 in the vein.While advancing the next pc400 through the px slim, the pc400 broke; subsequently, the physician removed part of the pc400 with the pusher assembly attached.The rest of the pc400 that was still inside the px slim was pushed into the vein.The procedure was complete with other pc400s, non-penumbra coils, and the same px slim.There was no report of an adverse effect to the patient.

Results: the pet lock was intact on the proximal end of its pusher assembly.The pusher assembly was kinked approximately 5.0 cm from its proximal end.The embolization coil was intact with its pusher assembly.Conclusions: evaluation of the first returned pc400 was unable to confirm the resistance experienced.Further evaluation revealed a proximal kink.This damage was not reported; therefore, is likely incidental to the reported event.The returned pc400 was able to be advanced through a demonstration microcatheter up to the kink without an issue.The reported event was unable to be confirmed.Evaluation of the second pc400 returned revealed an undamaged, functional device with the embolization coil intact with the pusher assembly.The reported event of a detached coil was not confirmed.This indicates the wrong device was 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.This report is associated with mfr report number: 3005168196-2020-00536 h3 other text : placeholder.
