1. An electrosurgical unit for creating an improved eschar in the stroma of tissue, comprising:

  • means for conducting a predetermined gas not containing oxygen in a jet to the tissue at a predeterined flow rate sufficient to clear natural fluids from fluid-perfused tissue and to substantially expose the tissue stroma; and

    means for transferring electrical energy at a predetermined radio frequency range in ionized conductive pathways at a predetermined power level within the gas jet in an electrical circuit which includes the tissue to create the eschar.
