1. A method of providing an instrument for a procedure, comprising:
- providing a tracking device configured to be in communication with a navigation system, wherein the instrument extending along a longitudinal axis, by;
providing a first tracking portion having a first length wrapped around the longitudinal axis for a first distance and includes a plurality of turns wherein each turn of the plurality of turns is formed at a first winding angle relative to the longitudinal axis to define a first wrap axis; and
providing a second tracking portion having a second length wrapped around the longitudinal axis for a second distance and includes a plurality of turns, wherein each turn of the plurality of turns is formed at a second winding angle relative to the longitudinal axis to define a second wrap axis;
providing the first tracking portion and the second tracking portion configured to be in communication with the navigation system;
providing the first tracking portion and the second tacking portion on the instrument to generate all of a first navigation vector and a second navigation vector to intersect near a single point in a single plane.

Abstract
Disclosed is a surgical navigation system for tracking an instrument relative to a patient. The system can track a portion of the patient, an instrument, and/or both relative to image data, a coordinate system, an atlas, a morphed atlas, or combinations thereof. The system can include a tracking device on the instrument to provide six degree of freedom information regarding the location of the instrument.

9. An instrument, comprising:
-
a tracking device formed around a longitudinal axis of the instrument, including; a first tracking portion formed of a first elongated member having a wrapped first length around the longitudinal axis for a first distance, wherein the wrapped first length includes a plurality of turns and each turn of the plurality of turns of the first elongated member is formed at a first winding angle relative to the longitudinal axis to define a first wrap axis; and a second tracking portion formed of a second elongated member having a wrapped second length around the longitudinal axis for a second distance, wherein the wrapped second length includes a plurality of turns and each turn of the plurality of turns of the second elongated member is formed at a second winding angle relative to the longitudinal axis to define a second wrap axis; a third tracking portion formed of a third elongated member having a wrapped third length around the longitudinal axis for a third distance, wherein the wrapped third length includes a plurality of turns and each turn of the plurality of turns of the third elongated member is formed at a third winding angle relative to the longitudinal axis to define a third wrap axis; wherein the first tracking portion is configured to define a first navigation vector, the second tracking portion is configured to define a second navigation vector, and the third tracking portion is configured to define a third navigation vector. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A trackable instrument, comprising:
-
an instrument having at least an elongated portion extending along a longitudinal axis; a tracking device, including; a first tracking portion of a first material having a first plurality of turns around the elongated portion, wherein each turn of the first plurality of turns is formed at a first winding angle relative to the longitudinal axis; a second tracking portion of a second material having a second plurality of turns around the elongated portion, wherein each turn of the second plurality of turns is formed at a second winding angle relative to the longitudinal axis, wherein the second winding angle is different from the first winding angle; and a third tracking portion of a third material having a third plurality of turns around the elongated portion; wherein the first tracking portion defines a first navigation vector and the second tracking portion defines a second navigation vector to determine an orientation of at least a first section of the elongated portion; wherein each turn of the third plurality of turns is formed at a third winding angle relative to the longitudinal axis. - View Dependent Claims (18, 19, 20, 21, 22)
