Classification: CPC A  H | IPC A

Claim 0:
1. A tool assembly for use with an electrosurgical device for cutting tissue comprising:
an active lead adapted to be electrically coupled to a first electrical potential, the active lead including a stem portion and a wire portion distal of the stem portion;
an electrical insulator coupled to the stem portion of the active lead, the electrical insulator including opposing first and second arms and a distal portion defining opposing first and second grooves such that a first segment of the active lead extends out of the first groove and into the first arm and a second segment of the active lead extends out of the second groove and into the second arm; and
a return lead adapted to be electrically coupled to a second electrical potential, the return lead defining a cavity configured to receive a portion of the electrical insulator within the cavity, the return lead defining an aperture configured for passage of a portion of the electrical insulator through the aperture and out of the cavity, and the return lead defining opposing slots configured to receive the respective opposing first and second arms of the electrical insulator such that the first and second segments of the active lead are laterally spaced apart from the return lead, wherein, upon activation, electrosurgical energy is transmitted between the first and second electrical potentials and through tissue disposed between the active and return leads.
