Patent ID: 7395110

Claim:
An electrode assembly for electroporation of a tissue surface, comprising: a non-conductive carrier having a proximal surface, a distal surface, and a plurality of through holes from the proximal surface to the distal surface; a plurality of first electrodes disposed on the proximal surface; a first conductor disposed on at least a first portion of the distal surface and extending through at least a first portion of the plurality of through holes and connected to the first electrodes on the proximal surface; a plurality of second electrodes disposed on the proximal surface; and a second conductor disposed on at least a second portion of the distal surface and extending through at least a second portion of the plurality of through holes and connected to the second electrodes on the proximal surface; wherein the first electrodes are in closely spaced relation with the second electrodes on the proximal surface for engaging the tissue surface and applying an electric field.
