Abstract
An assembly of a contour-type electrosurgical dispersive electrode and a surgical drape, the electrode having a contact surface with the skin in which its perimeter electrically and/or geometrically bounds a region of the surface of the body which contains the surgical field. The electrode is formed by one or more electrically conductive zones linked together conductively and/or capacitively.
