Abstract: An electroporation catheter for ablation of cardiac tissue is disclosed. The electroporation catheter includes an elongated, shaft having a distal region and a deflection plane. The elongated shaft defines an axis. An electrode assembly is operably coupled to the distal region and configured to generate an electric field. The electrode assembly includes splines each supporting an ablation electrode. The splines are transitionable between a collapsed configuration and an expanded configuration. A deflector in the distal region is actuatable in the expanded configuration to deflect the electrode assembly off the axis toward a deflection direction in the deflection plane. In the expanded configuration, a first set of splines are proximate the deflection direction and a second set of splines are distal the deflection direction. An insulator is disposed on the second set of splines so as to insulate at least a portion of each associated ablation electrode.
