A visual and functional analysis was performed on the returned device.The reported difficulty positioning (visibility) could not be confirmed.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.The investigation determined the cause for the reported difficulty positioning is related to the circumstances of the procedure.In this case, it is likely that patient anatomy and or fluoroscopy equipment affected the visibility.There is no indication of a product quality issue with respect to the design, manufacture, or labeling of the device.
