Patent application number	Description	Published
20100331671	Method and System for Navigating a Catheter Probe in the Presence of Field-Influencing Objects - A system for and method of determining and compensating for the effect of a field influencing object on a field sensor, preferably a coil, that is within a navigational domain. The navigational domain contains navigational magnetic energy and disturbing magnetic energy, and the field influencing object produces the disturbing magnetic energy in response to the navigational magnetic energy. The correction system includes a first transmitter for projecting into the navigational domain field energy in a first waveform sufficient to induce a first signal value in the sensing coil. The system also includes a second transmitter for projecting into the navigational domain field energy in a second waveform sufficient to induce a second signal value in the sensing coil. The system further includes a signal processor for receiving the first signal value and for receiving the second signal value to determine the effect of the electrically conductive object on the field sensor. In other embodiments, the correction system may utilize a second sensing coil to receive and process an alternate aspect of the field energy from a position that is different from the first field sensor, or the system may utilize a storage device that contains information relating to the effect of the field influencing device within the navigational domain.	12-30-2010

20090287443	Method for Calibrating a Navigation System - 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.	11-19-2009

20100022873	Navigation System for Cardiac Therapies - An image guided catheter navigation system for navigating a region of a patient includes an imaging device, a tracking device, a controller, and a display. The imaging device generates images of the region of the patient. The tracking device tracks the location of the catheter in the region of the patient. The controller superimposes an icon representing the catheter onto the images generated from the imaging device based upon the location of the catheter. The display displays the image of the region with the catheter superimposed onto the image at the current location of the catheter.	01-28-2010
20100152571	COMBINATION OF ELECTROMAGNETIC AND ELECTROPOTENTIAL LOCALIZATION - 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.	06-17-2010
20100210939	Method and Apparatus for Surgical Navigation - 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.	08-19-2010
20100274124	Method and Apparatus for Surgical Navigation - A surgical navigation system for navigating a region of a patient that may include a non-invasive dynamic reference frame and/or fiducial marker, sensor tipped instruments, and isolator circuits. The dynamic reference frame may be placed on the patient in a precise location for guiding the instruments. The dynamic reference frames may be fixedly placed on the patient. Also the dynamic reference frames may be placed to allow generally natural movements of soft tissue relative to the dynamic reference frames. Also methods are provided to determine positions of the dynamic reference frames. Anatomical landmarks may be determined intra-operatively and without access to the anatomical structure.	10-28-2010
20110054293	Combination Localization System - 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.	03-03-2011
20110054304	Combination Localization System - 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.	03-03-2011
