Event or Problem Description
The patient was undergoing a coil embolization procedure to treat a dural arteriovenous fistulas (davf) using penumbra smart coils (smart coils) and a non-penumbra microcatheter.It was reported that the patient anatomy was tortuous, calcified, and narrowed.During the procedure, the physician implanted four smart coils in the target vessel using the microcatheter.However, the next smart coil would not advance within its introducer sheath and was stuck at the initial position.Therefore, the smart coil was removed.The procedure was completed using another nineteen smart coils and the same microcatheter.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 mid-joint was proximal to the introducer sheath friction lock.The embolization coil was intact with its pusher assembly and undamaged.Conclusions: evaluation of the returned smart coil revealed that the pusher assembly mid-joint was retracted proximal to the introducer sheath friction lock.If this occurs, resistance will likely be experienced while advancing the device.During functional testing, the pusher assembly mid-joint was advanced through the introducer sheath friction lock with resistance.Then the device was able to advance through its introducer sheath and a demonstration microcatheter without issue.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.
