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.
