    Abstract: An instrument tracking device for cooperating with an instrument during a surgical procedure where the instrument has an elongated body extending along a first longitudinal axis and including a working member at a distal tip includes a body having a distal end and a proximal end. An opening can be formed through the body along a second longitudinal axis. The opening can define a passthrough in the body from the distal end to the proximal end. A first tracking coil can be disposed in the body and can define a first tracking coil axis that is substantially coaxial with the second longitudinal axis of the body. A connection mechanism cooperates between the elongated housing and the body that secures the body to the elongated housing of the instrument upon passing at least a portion of the elongated housing through the passthrough of the body in an assembled position.

  • Patent number: 9113812
    Abstract: A system can include an implantable device, an instrument, a display device and a processor. The implantable device can include a port and a localizer for generating a navigation field. The instrument can include a tracking device for sensing the navigation field. The processor can be operably coupled to the tracking and display devices and operable to determine a real-time location of the instrument relative to the port and a trajectory of the instrument relative to an insertion axis of the port. The processor system can be operable to cause the display device to graphically render the instrument as a plurality of two or three-dimensional rings positioned around an axis coincident with the determined trajectory and in spaced relation to each other along the axis. A first ring of the plurality of rings can be positioned at the determined instrument location relative to a graphical representation of the port location.
