1. A mapping catheter, the mapping catheter comprising:
an elongated catheter body comprising a proximal end and a distal end, and defining a catheter longitudinal axis extending between the proximal and distal ends;
a flexible tip assembly coupled to the distal end of the catheter body and adapted to conform to tissue, the flexible tip assembly comprising a plurality of electrode-carrying arms that lie in a common plane and that form a plurality of offset loops; and
a plurality of electrodes disposed on the plurality of electrode-carrying arms, wherein the plurality of electrodes are arranged in a planar array comprising a plurality of rows of longitudinally-aligned electrodes aligned parallel to the catheter longitudinal axis and wherein the plurality of electrode-carrying arms comprise longitudinally-extending arms, wherein each row of longitudinally-aligned electrodes comprise eight ring electrodes distributed along each of the longitudinally-extending arms.
