1. An electroporation therapy system, comprising:

  • a device having proximal and distal ends;

    an electrode assembly comprising a plurality of electrically isolated electrode elements disposed at said distal end of said device;

    a detector coupled to said elements configured to identify which elements have a conduction characteristic indicative of contact with tissue; and

    an electroporation generator configured to energize said identified electrode elements in accordance with an electroporation energization strategy, wherein said plurality of electrode elements are arranged in at least a first array disposed on an outer surface of a tubular base wherein said tubular base comprises electrically-insulating material, said array extending along a first path having a shape substantially matching that of said base, an electroporation generator being configured to selectively energize said identified electrode elements of said first array in a bipolar fashion so as to produce a lesion in said tissue having said shape, and wherein said plurality of electrodes are further arranged in a second array disposed on said outer surface of said tubular base, said second array being offset from said first array by a predetermined distance and extending along a second path having said shape, said electroporation generator being further configured to selectively energize said identified electrode elements of said first and second array in a bipolar fashion therebetween so as to produce a lesion in said tissue having said shape and width corresponding to said predetermined distance.
