Abstract
An electrosurgical device to generate a plasma stream and method to perform endoscopic or laparoscopic surgery within a patient's body. The electrosurgical device includes an electrode operatively coupled to an electrosurgical generator to receive electrical energy therefrom, the electrode being concentrically disposed within an inner noble gas conduit to form a plasma channel. An outer electronegative gas conduit is disposed in surrounding coaxial relation relative to the inner noble gas conduit to cooperatively form an electronegative gas channel therebetween such that the electrode heats the noble gas to at least partially ionize the noble gas to generate the plasma stream to be directed to the surgical site to perform the surgical procedure while the electronegative gas sustains the plasma stream at the surgical site and dilutes the noble gas adjacent the surgical site. An outer aspiration conduit may be provided to remove fluid and solid debris from the surgical site.
