Apparatus and method for treating cardiac arrhythmias
First Claim
1. A method of treating cardiac arrhythmias, which comprises the steps of:
- (a) positioning the distal tip of each of one or more catheters at a site adjacent to or within a patient'"'"'s heart;
(b) sensing location information at the site;
(c) sensing local information concerning the heart'"'"'s electrical activity at the site;
(d) processing sensed information from steps (b) and (c) to create one or more data points;
(e) repeating steps (a) , (b) , (c) and (d) one or more times to create sufficient data points for a map of the heart'"'"'s electrical pathways; and
(f) ablating a portion of the heart whose electrical pathways cause said arrhythmias.

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.
