The catheter allows mapping and/or ablation of the area around two or more PVostiaat the same time, with a single placement of a distal section of the catheterhaying a 2Dconfiguration resembling an infinity or lazy 8 symbol. The catheter has anelongatedcatheter body, a distal section haying at least a flexible elongated memberwith shapememory, the member being configured to assume a 2D configuration resembling aninfinitysymbol, and at least one electrode mounted on the member. The 2D configurationresembles a first loop and a second loop, wherein the first and second loopsare side-by-side,generally extending in a common plane.
