ABSTRACT:
A multipolar electrode catheter includes a central and four side electrodes at its distal end. The catheter is actuable from a retracted or collapsed mode wherein the side electrodes are arranged around the tubular catheter outer surface to an expanded mode. A plurality of longitudinal slits in the catheter wall enable radial expansion of the distal end so that the side electrodes are moved to an operative position radially outward from their position in the retracted mode. In the expanded position, the side electrodes lie in the same plane and equally spaced from adjacent electrodes. Electrode leads connected to the electrodes enable the electrodes to be used both for mapping and ablation of endocardial sites.
