The device was returned for analysis.The reported material separation was able to be confirmed.The reported difficult to remove was unable to be replicated in a testing environment due to the condition of the returned device.A review of the lot history record identified no manufacturing nonconformities issued to the reported lot that would have contributed to this event.Additionally, a review of the complaint history identified no other incidents from this lot.As there was no reported damage noted to the device during the inspection prior to use, the investigation determined the reported difficulties appear to be related to circumstances of the procedure as it is likely that during removal interaction with the sheath resulted in the reported difficult to remove and ultimately resulted in the reported tip/noted inner member material separation.As reported, the nose cone embolized and is free floating in the anatomy in a non-eloquent branch of the popliteal artery.There is no indication of a product quality issue with respect to manufacture, design or labeling.
