ABSTRACT:
A probe for cardiac diagnosis and/or treatment has a catheter tube. The distal end of the catheter tube carries first and second electrode elements. The probe includes a mechanism for steering the first electrode element relative to the second electrode element so that the user can move the first electrode element into and out of contact with endocardial tissue without disturbing the contact of the second electrode element with endocardial tissue, even through the two electrode elements are carried on a common catheter tube. The distal end can carry a three dimensional structure having an open interior area. One of electrode elements can be steered through the open interior area of the structure. Electrode elements on the exterior of the structure can be used for surface mapping, while the electrode element inside the structure is steered to ablate tissue.
