Abstract

See full text

A bipolar electrode assembly includes a substrate having proximal and distal ends and supports first electrode and second electrodes. The first and second electrodes are disposed in an interwoven configuration across the surface of the substrate from the proximal to distal ends. A cooling medium is disposed interposed between the first and second electrodes from the proximal to distal ends. The first and second electrodes each include a plurality of finger-like prongs which either extend lengthwise or transversely or the first and second electrodes extend spiral inwardly along the surface of the substrate. The prongs of the first electrode intermesh with the prongs of the second electrode. Each prong is separated by the cooling medium. First and second electrodes may be disposed in a lengthwise alternating configuration across the surface of the substrate with a cooling medium disposed in vertical registration thereunder.
