ABSTRACT:
A recording and ablation catheter method and system for creating linear lesions in an atrial or other chamber of a heart is disclosed which includes an array of readily controlled electroded arcuate distal working catheter shapes that are easily deployed to contact the inner wall surface of the right atrial cardiac chamber in a manner that enables easy recording and mapping of impulses and thereafter facilitates sustained contact so that linear lesions can be produced from an array of mapping and ablation electrode devices serially spaced along the working catheter shape.
