1. An apparatus for coagulating tissue, comprising:

  • a gas-delivering device defining an outlet and adapted to deliver, in use, a plasma comprised of an ionized inert gas from the outlet of the gas-delivering device;

    an electrode adapted to supply a high-frequency current, a distal end of the electrode projecting out of the gas-delivering device; and

    a guiding device disposed at a distal end of the electrode, wherein a cross-section of at least a portion of said guiding device is at least a size of an opening of said outlet at a furthest distal end of said gas-delivering device in order to divert said plasma substantially radially with respect to an opening of said outlet of said gas-delivering device, and wherein the outlet of the gas-delivering device and the guiding device are adapted such that at least a portion of the plasma is directed to a tissue to be treated, regardless of a position of the tissue relative to a rotational position of the outlet of the gas-delivering device.
