1. An electrosurgical method for simultaneously cutting and coagulating tissue with an electrosurgical device having an electrode and a channel wherein said channel has a port near a proximal end of said electrode for directing a gas onto said proximal end of said electrode, the method comprising the steps of:

  • causing a gas to flow through said channel and exit said port;

    applying high-frequency energy to said electrode while said gas flows through said channel, wherein said high-frequency energy applied to said electrode continuously plasmatizes gas exiting said port;

    initiating an electrical discharge from said electrode through said continuously plasmatized gas to said tissue;

    cutting tissue with said electrode;

    maintaining said electrical discharge from said electrode through said plasmatized gas while cutting tissue with said electrode to cause coagulation of tissue adjacent said proximal end of said electrode simultaneously with said cutting.
