Abstract
An electrosurgical device for cutting tissue includes a body portion and a tool portion extending distally from the body portion. The tool portion defines a longitudinal axis. The tool portion includes a return lead adapted to be electrically coupled to a return terminal of an electrosurgical energy source, first and second electrical insulators disposed on a first surface of the return lead, and an active lead adapted to be electrically coupled to an active terminal of the electrosurgical energy source. The first electrical insulator is disposed distal of the second electrical insulator. The active lead extends through the first and second electrical insulators such that the active lead and the first surface of the return lead define a gap therebetween. Upon activation of the electrosurgical energy source, electrosurgical energy is transmitted from the active lead through tissue to the return lead to cut the tissue.
