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.

Method and apparatus for surgical navigation

A method and apparatus for electromagnetic navigation of a surgical probe near a metal object. The electromagnetic navigation system includes a transmitter coil array and a shield. The transmitter coil array has a plurality of transmitter coils and is operable to generate the electromagnetic field to navigate the probe. The shield is positioned adjacent the metal object and is operable to shield the metal object from the electromagnetic field generated by the transmitter coil array, such that the shield substantially reduces distortion of the electromagnetic field by the metal object.

Method for calibrating a navigation system

A support tool for a supply assembly delivers a functional fluid to an implantable medical device. The supply assembly defines a supply axis. The support tool includes a support member defining an opening. The opening has a support axis, and the opening is configured to receive the supply assembly. The support member includes a three dimensionally contoured nesting surface that conforms to a corresponding three dimensionally contoured surface of the supply assembly. The corresponding surface of the supply assembly nests against the nesting surface to support the supply assembly such that the supply axis remains substantially fixed relative to and aligned with the support axis.

Method and apparatus for guiding an external needle to an implantable device

A support tool or a supply assembly that delivers a functional fluid to a patient includes an antenna array for receiving or sensing a navigation field. The navigation field can be generated from a localizer. The localizer can be incorporated or included in an implanted device.

A system to generate a navigation field relative to an implanted device is disclosed. The system can include a small and/or thin localizer array positioned in the implanted device. A power management scheme and circuits can be provided to conserve and resource power in the implanted device.

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.

A patient defines a patient space in which an instrument can be tracked and navigated. An image space is defined by image data that can be registered to the patient space. A tracking device can be connected to a member in a known manner that includes imageable portions that generate image points in the image data. Selected image slices or portions can be used to register reconstructed image data to the patient space.

System and method for automatic registration between an image and a subject

A navigation system or combination of navigation systems can be used to provide two or more types of navigation or modalities of navigation to navigate a single instrument. The single instrument can be positioned within the patient and tracked. For example, both an Electromagnetic (EM) and Electropotential (EP) navigation system can be used to navigate an instrument within a patient.

Combination of electromagnetic and electropotential localization

A surgical navigation system for navigating a region of a patient includes a non-invasive dynamic reference frame and/or fiducial marker, sensor tipped instruments, and isolator circuits. The dynamic reference frame may be repeatably placed on the patient in a precise location for guiding the instruments. The instruments may be precisely guided by positioning sensors near moveable portions of the instruments. Electrical sources may be electrically isolated from the patient.

Method of forming an electromagnetic sensing coil in a medical instrument

A navigation system or combination of navigation systems can be used to provide two or more navigation modalities to navigate a single instrument in a volume. For example, both an Electromagnetic (EM) and Electropotential (EP) navigation system can be used to navigate an instrument within the volume. Image data can also be illustrated relative to a tracked position of the instrument in the volume for navigation.
