A cutting element for an electrosurgical device. The cutting element includes an elongate non-conductive body having a first face opposite a second face, the first face and the second face defining an edge there between. A conductive element is disposed only along the edge, the conductive element being configured to cut tissue with monopolar radiofrequency energy.

Electrosurgical blade with minimally exposed edge, alternative to coated blade

An electrosurgical hand piece device is configured to cut tissue with monopolar RF energy to extract a medical lead submersed in fluid. The device includes an electrode surrounded by an electrically insulating coating that can be exposed from a distal edge of the electrode when power is supplied to the device, thereby focusing the energy at the distal edge and enabling tissue to be more easily and safely cut from around the medical lead while in fluid.
