Multi-configuration tracknig array and related method
First Claim
1. A navigation system that determines a location of a portion of a first medical instrument relative to a patient, the navigation system comprising:
- a multi-configuration tracking array that extends from the first medical instrument;
a plurality of tracking devices positioned on said multi-configuration tracking array, wherein at least one of said tracking devices changes to define at least a first condition and a second condition; and
a tracking system that detects said tracking devices and relates a change between said first condition and said second condition with a change between at least a first instrument configuration and a second instrument configuration.

Abstract
A navigation system generally determines a location of a portion of a first medical instrument relative to a patient. The navigation system generally includes a multi-configuration tracking array that extends from the first medical instrument. A plurality of tracking devices can be positioned on the multi-configuration tracking array. At least one of the tracking devices changes to define at least a first condition and a second condition. A tracking system detects the tracking devices and relates a change between the first condition and the second condition with a change between at least a first instrument configuration and a second instrument configuration.

35. A method of performing a procedure with a first instrument so that a configuration of the first instrument is included with a view produced from a surgical navigation process used to perform the procedure, the method comprising:
-
detecting tracking devices on a multi-configuration tracking array having a tracking device holder member that connects to an instrument holder member that extends from the first medical instrument; moving said tracking device holder member relative to said instrument holder member between a first position and a second position; detecting said moving of said tracking device holder member; and relating said moving of said tracking device holder member between said first position and said second position with a change between a first instrument configuration and a second instrument configuration. - View Dependent Claims (36, 37, 38, 39)

40. A navigation system that determines a location of a portion of a medical instrument relative to a patient, the navigation system comprising:
-
a multi-configuration tracking array that extends from the medical instrument; at least two tracking devices positioned on a handle portion of the medical instrument; at least one tracking device positioned on a first removable tip portion of the medical instrument that is capable of coupling to said handle portion and that establishes a first pattern; at least one tracking device positioned on a second removable tip portion of the medical instrument that is capable of coupling to said handle portion and that establishes a second pattern; and a tracking system that detects said tracking devices and relates a change between said first pattern and said second pattern with a change between at least a first instrument configuration that defines the first tip portion being connected to the handle portion and a second instrument configuration that defines the second tip portion being connected to the handle portion. - View Dependent Claims (41, 42, 43, 44, 45, 46, 47, 48)
