ABSTRACT:
An improved ablation catheter with at least one multiple-needle electrode can be used in ablating the arrhythmogenic region instead of an arrhythmogenic point of a patient. This catheter is particularly useful for treating the patient with atrial fibrillation (AFib) indications. A catheter suitable for radiofrequency ablation of cardiac tissues comprises a delivery catheter and an inner catheter having a distal section, a distal end, a proximal end and at least one lumen extending therebetween. The ablation catheter has a temperature sensor and a close-loop temperature control. The steerable catheter having at least one multiple-needle electrode is inserted into the chambers of the heart to create a plurality of deep, large, and contiguous lesions by applying radiofrequency energy to said electrode.
