ABSTRACT:
An electric field concentrated electrosurgical electrode (e.g., blade or the like) wherein there is provided a conducting member having an edge that is at least partly sharpened and coated with electrical insulating material so as to produce a highly concentrated electric field and a highly concentrated transfer of electric energy thereacross by capacitive coupling. In the preferred embodiment, the working surfaces of a sharpened surgical implement, including the sharpened part, are entirely coated with a layer of non-stick insulating material.
