Abstract:
1. An ablation catheter adapted to ablate atrial wall tissue, comprising: an inner catheter tube; an outer catheter tube slidably mounted on the inner catheter tube; an electrode array having at least two resilient arms coupled to the inner catheter tube, each of the at least two resilient arms having a delivery configuration and an expanded configuration and comprising a distal arm section, a proximal arm section, and a bend section disposed between the distal arm section and the proximal arm section; and a plurality of electrodes coupled to the distal arm section of each of the at least two resilient arms, wherein each of the resilient arms is disposed within the outer catheter tube in the delivery configuration and each of the resilient arms is withdrawn from the outer catheter tube in the expanded configuration to form a planar array of substantially triangular faces oriented parallel to a longitudinal axis of the catheter.
