Abstract

A system for mapping electrical activity of a patient's heart includes a set of electrodes (19) spaced from the heart wall (18) and a set of electrodes (24, 26) in contact with the heart wall (18). Voltage measurements from the electrodes are used to generate three-dimensional and two-dimensional maps of the electrical activity of the heart.

Claims (12)

1.

measuring the geometric shape of said heart chamber, and generating volume data from said geometric shape measurement;
computing the position of said electrode array (19) within said heart chamber, from said volume measurement, and from said reference position, and generating array position measurement data;
measuring electrical potentials on said array, and generating electrical potential measurement data;
computing the three-dimensional volumetric electrical field distribution of said heart chamber volume from a solution to LaPlace's equation containing said electrical potential measurements, and said array position measurement data;
displaying said volumetric electrical field distribution.

a set of electrodes (19);
first positioning means coupled to said set of electrodes for spacing a portion of said set of electrodes, defined as a first subset of electrodes, apart from and not in contact with a surface of said patient's heart (12);
second positioning means coupled to said set of electrodes for placing a second predetermined subset of said set of electrodes (24) into contact with a surface of said patient's heart;
third positioning means coupled to said set of electrodes for placing a third predetermined subset of said electrodes (26) into a position in a wall of said patient's heart.
4. The apparatus of claim 3 wherein said set of electrodes exceeds twelve electrodes.
5. The apparatus of claim 3 wherein said first subset of electrodes exceeds one.

a reference catheter (16) having a tip electrode assembly;
said reference catheter (16) being located in said lumen and supported for relative motion with respect to said electrode array such that said tip electrode assembly may be placed into contact with said patient's heart when said array is in said heart chamber.
11. The catheter assembly (10) of claim 10 further comprising:
means for excluding blood (77) from the interior of said deformable lead body when said deformable lead body is in said second expanded position.
12. A method of forming a catheter comprising the steps of:
a) forming a collection of insulated wires each having an interior conductor, and each having an exterior insulation coating;
