Electrode Assembly For Catheter System

In an electrode assembly for a catheter system, a plurality of struts extends from a proximal end to a distal end of the electrode assembly. Each strut has a longitudinally extending proximal leg, a longitudinally extending distal leg, and a center segment extending between and interconnecting the proximal leg and the distal leg. A hinge interconnects the proximal leg and the center segment, and another hinge interconnects the distal leg and the center segment. The center segment of each of the struts has a corresponding electrode thereon. The electrode assembly is configurable between a collapsed configuration and an expanded configuration, with the electrodes being transversely spaced from the longitudinal axis of the electrode assembly a greater distance in the expanded configuration than in the collapsed configuration.
