1. An electroporation therapy system, comprising:
a device having proximal and distal ends;
an electrode assembly comprising a plurality of electrically isolated ring electrode elements disposed at said distal end of said device, wherein said plurality of electrode elements are disposed on an outer surface of a base, wherein said base comprises electrically-insulating material, said base having an arcuate shape; and
an electroporation generator coupled to said electrode elements and configured to energize said one or more of said electrode elements in accordance with an electroporation energization strategy, said electroporation generator being configured to selectively energize said one or more electrode elements in a bipolar fashion so as to produce a lesion in a tissue,
wherein said electroporation energizing strategy is an electroporation-induced primary necrosis therapy or an electric field-induced apoptosis therapy.
