Abstract

Abstract

An electrode catheter is disclosed for creating a linear lesion in heart tissue of a heart chamber in order to correct cardiac arrhythmia. The catheter is elongated in dimension such that, upon insertion of the catheter in the patient, the catheter substantially continuously contacts either the endocardial or epicardial heart tissue. The catheter includes a plurality of electrodes and the electrodes are positioned at spaced intervals along the catheter. The electrodes are then sequentially energized with a radio frequency in conjunction with a back plate attached to the patient such that the electrodes form a continuous lesion conforming in shape to the shape of the catheter on the heart tissue. This lesion, furthermore, is of sufficient depth such that the lesion interrupts electrical nodal conduction across the lesion.
