A medtronic representative reported that, while in a cranial biopsy procedure, the biopsy needle could not be detected by the navigation system camera.Every other device was being detected.Surgeon tried cleaning the spheres and opened a new needle with a different lot number.The camera would still not detect the needle.The biopsy procedure was selected on the navigation system.The surgeon proceeded to take a biopsy with the needle.The surgeon knew the distance to target and just set the stop on the needle to this measurement and proceeded to take a biopsy without navigation.The surgeon opted to continue and completed the procedure without the use of the navigation system.Delay in therapy was less than one hour.There was no impact on patient outcome.
