Abstract: A system for navigating a medical device is provided. In one embodiment, a magnetic field generator assembly generates a magnetic field. Position sensors on the medical device, on an imaging system and on the body generate signals indicative of the positions within the magnetic field. The generator assembly and reference sensors are arranged such that a correlation exists between them and the positions of the body and of a radiation emitter and a radiation detector of the imaging system. An electronic control unit (ECU) determines, responsive to signals generated by the sensors, a position of the medical device, a position of one of the radiation emitter and detector and a distance between the emitter and detector. Using this information, the ECU can, for example, register images from the imaging system in a coordinate system and superimpose an image of the device on the image from the imaging system.

Abstract: A catheter configured for use with a magnetic field-based localization system includes a distributed location sensor that includes a plurality of individual location sensing coils electrically connected in series. The distributed location sensor has an effective magnetic center based on the individual characteristics of each location sensing coil. The effective magnetic center can be located in a space occupied by another structure such as an irrigation fluid delivery tube. The plurality of individual location sensing coils are generally smaller, thereby easing placement, and collectively, when connected in series, output a relatively strong and noise-free signal.

Abstract: An apparatus for displaying a moving region of interest located within a body includes a positioning system to determine a position and orientation (P&O) of a medical device as well as to track, using an internal position reference sensor, the motion of the region of interest over time. A compensation function block generates a motion compensation function based on the motion of the region of interest, which is configured to compensate for the motion of the region of interest between a first time, for example a time at which an image was acquired and a second time, for example a time at which a P&O of the device was measured. The measured P&O is corrected using the compensation function. A representation of the medical device is superimposed on the image in accordance with the corrected P&O.
