Electroporation systems and catheters for electroporation systems

An electroporation catheter comprising:

• a plurality of catheter electrodes disposed along a portion of a distal end of the electroporation catheter, the plurality of catheter electrodes comprising:
• a plurality of first type catheter electrodes adapted for use with an electroporation generator during an electroporation procedure;
• and
• a plurality of second type catheter electrodes adapted for use with the electroporation generator during the electroporation procedure and for use with a diagnostic subsystem, wherein each second type catheter electrode is adjacent another second type catheter electrode, and wherein both the first type catheter electrodes and the second type catheter electrodes are selectively couplable to the electroporation generator to deliver energy as part of the electroporation procedure;
• a first wire connected to all of the plurality of first type catheter electrodes;
• and
• a plurality of second wires, each second wire of the plurality of second wires connected to an associated one of the plurality of second type catheter electrodes, wherein, to perform the electroporation procedure, the second type catheter electrodes are selectively couplable to the first type catheter electrodes using switching circuitry connected to the first wire and the plurality of second wires.
