    摘要： Non-thermal plasma is a partly ionized gas, which can be generated by a high-voltage electric field at a low pressure. Disclosed herein are apparatuses and methods for treating an enteric disease in vivo using non-thermal plasma. The disclosed apparatuses have a first conduit comprising a lumen and a tip; a first electrode disposed within the lumen of the first conduit; a second electrode comprised of a metal conduit disposed within the first conduit; an insulator disposed within the lumen of the first conduit, the insulator configured to electrically insulate the first electrode from the second electrode; and a gas channel disposed between the outer surface of the metal conduit and the inner surface of the first conduit, the gas channel being capable of feeding a gas from a gas source to the tip, wherein when the potential is applied, the gas is ionized to produce the non-thermal plasma.

    摘要： Method for the non-thermal treatment of human or animal tissue with high-voltage electrical discharge plasma is disclosed. The disclosed method employs current through plasma and through tissue not for the purpose of heating the tissue, but instead to maintain the plasma proximate to the tissue being treated. Also disclosed is a method of limiting the current through plasma and through tissue to minimize tissue heating by placement of an insulator or semiconductor between an electrode and tissue resulting in generation of a high-voltage discharge similar to a dielectric barrier discharge. The disclosed non-thermal plasma treatment can be employed to promote coagulation of blood, sterilization, disinfection, re-connection of tissue, and treatment of tissue disorders without causing significant thermal tissue damage.
