Abstract

This invention concerns an apparatus and method for the treatment of cardiac arrhythmias. More particularly, this invention is directed to a method for ablating a portion of an organ or bodily structure of a patient, which comprises obtaining a perspective image of the organ or structure to be mapped; advancing one or more catheters having distal tips to sites adjacent to or within the organ or structure, at least one of the catheters having ablation ability; sensing the location of each catheter's distal tip using a non-ionizing field; at the distal tip of one or more catheters, sensing local information of the organ or structure; processing the sensed information to create one or more data points; superimposing the one or more data points on the perspective image of the organ or structure; and ablating a portion of the organ or structure.
