Abstract
A catheter system comprising a delivery catheter with distal and proximal ends; a handle attached to the proximal end of the delivery catheter; the delivery catheter having an electrode deployment means where said electrode deployment means includes a retractable tip section comprising a plurality of deployable parallel electrodes. The tip section has a non-deployed state when it is positioned in the delivery catheter. On the other hand, the tip section has a distended deployed state when it is advanced out of the distal end of said delivery catheter; wherein the deployed electrodes on the tip section has a preformed shape in a parallel manner. This catheter is particularly useful for treating the patient having tachycardia as a result of its more effective electrodes arrangement for intimate tissue contact.
