Description of Event or Problem

Medtronic received information regarding a navigation system being used outside of a procedure. It was reported that a biopsy guide (Precision Aiming Device), at the proximal screw where it mounted to the articulating arm, was not able to be tightened down. It was reported that the biopsy guide continued to rotate despite attempts to lock it into position because the screw would not tighten and the guide could not be locked or held in position. There was no patient involved.
