Medtronic received information regarding a navigation system being used for a cranial resection procedure.
It was reported that during the case, the surgeon was unable to verify the passive planar probe.
The system was displaying a high distance to divot value, and the spheres were flickering in the tracking view.
The site swapped to a new passive planar probe, new spheres, and a new cranial frame and the issue did not resolve.
The probe was unable to be verified and the site swapped to electromagnetic navigation to continue the case with the system.
There was a 2 hour delay to the procedure and no impact to patient outcome as a result of this issue.
