A personalized gripper, which is shaped based on the anatomical image to personally fit an organ of the specific patient at the selected location, and which includes a first position sensor of a position10 tracking system, is fitted. The anatomical image is registered with a coordinate system of the positiontracking system, by identifying the selected location in the anatomical image and measuring a first position of the first position sensor using the position-tracking 15 system. A medical device that includes a second position sensor of the position-tracking system, is navigated in the head of the specific patient by displaying a second position of the medical device in the head on the registered anatomical image. 3387040v11/3 _ _ _ _ _ _ _ _ _ _ _ 00 C' o 000 .. oc QI)
