Abstract
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.
