First Claim
1. An apparatus for creating a high resolution map of the electrical and mechanical properties of the heart comprising:
- a catheter;
a catheter guidance and control imaging system coupled to the catheter;
a data collection module for the catheter guidance and control imaging system to collect several different types of data from the catheter; and
a display for displaying the data collected by the catheter guidance and control imaging system in a three dimensional color-coded image format.

Abstract
A system method that tracks one or more points on the surface of a cardiac tissue throughout a cardiac cycle and collect various types of data points which are then subsequently used to generate a corresponding model of the tissue and display the model as a 3D color coded image is described. In one embodiment, the system determines the position and orientation of a distal tip of a catheter, manipulates the catheter tip so as to maintain constant contact between the tip and a region of cardiac tissue using the impedance method, acquires positional and electrical data of the tip-tissue configuration through an entire heartbeat cycle, repeats the measurements as many times as needed in different tissue regions, and forms a 3D color coded map displaying various mechanical and electrical properties of the heart using the acquired data.

14. A method of creating a high resolution map of the electrical and mechanical properties of the heart comprising:
-
determining the position and orientation of a tip of a catheter within a patient'"'"'s heart using a catheter guidance and imaging system operatively coupled to the catheter; changing the position of the catheter tip by altering the shape and polarity of a surrounding magnetic field; guiding the distal tip to a desired position along the inner surface of the heart wall; maintaining the catheter tip at the desired position along the inner surface of the heart wall for at least a portion of cardiac cycle; acquiring first data based on the patient and the distal tip during a cardiac cycle; calculating one or more electrical and mechanical properties of the heart from the first data; processing the first data into a three dimensional color-coded image according to the various electrical and mechanical properties; and displaying the three dimensional color-coded image on a display. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22)
