ABSTRACT:
A cardiac navigation system including a mapping catheter, a control system coupled to the mapping catheter, an electrode array, and means for driving an electrical current across the electrode array. The mapping catheter includes means for sensing an electrical field. The control system includes means for receiving sensed signals from the mapping catheter. The cardiac navigation system includes at least one electrode array including means for providing an electrical field across three axes. The three axes are approximately orthogonal with respect to one another. The means for driving an electrical current across the three axes includes means for providing a plurality of individual current sources to the electrode array. As such, the cardiac navigation system presented provides a more uniform sheet of current across an area of interest, the mapping catheter senses the electrical field across the area of interest, and the control system determines a three-dimensional location of the mapping catheter based on the sensed electrical field.
