Abstract:
1. A system comprising: an implantable device having a port and a localizer configured to generate a navigation field, the port including an insertion axis; an instrument including a tracking device configured to sense the navigation field; a display device; and a processor system operable with the tracking device and the display device and configured to determine a real-time location of the instrument relative to the port and a trajectory of the instrument relative to the insertion axis of the port; wherein the processor system is configured to cause the display device to graphically render the instrument in the form of a plurality of two or three-dimensional rings positioned around an axis coincident with the determined trajectory and in an axially spaced apart relation to each other along the axis, and wherein a first ring of the plurality of rings is positioned at the determined location of the instrument relative to a graphical representation of the location of the port.
