1. An ultrapolar electrosurgery blade comprising:
a top thin elongated conductive member and a bottom thin elongated conductive member in vertical alignment with one another and spaced apart from one another along their lengths to form a space between the top and bottom thin elongated conductive members wherein each of the top and bottom thin elongated conductive members includes opposing planar sides, a sharp cutting end and an opposite non-cutting end;
a non-conductive housing that covers both opposing planar sides of the top and bottom thin elongated conductive members and that fills the space between the top and bottom thin elongated conductive members to create opposing non-conductive sides of the ultrapolar electrosurgery blade wherein at least a portion of the sharp cutting ends of the top and bottom thin elongated conductive members and their opposite non-cutting ends remain exposed, and wherein at least a portion of a top of the top thin elongated conductive member is exposed between portions of non-conductive housing located on a top of the ultrapolar electrosurgery blade and at least a portion of a bottom of the bottom thin elongated conductive member is exposed between portions of non-conductive housing located on a bottom of the ultrapolar electrosurgery blade; and
both a return conductive contact layer and an active conductive contact layer positioned on each of the opposing non-conductive sides of the ultrapolar electrosurgery blade wherein the return conductive contact layers on each of the opposing non-conductive sides of the ultrapolar electrosurgery blade are connected to one another by extending the return conductive contact layers over the top or bottom of the ultrapolar electrosurgery blade and the active conductive contact layers on each of the opposing non-conductive sides of the ultrapolar electrosurgery blade are connected to one another by extending the active conductive contact layers over the top or bottom of the ultrapolar electrosurgery blade.
