Abstract: A kit of parts for use in treatment of tissue by a contained plasma and/or plasma products is disclosed. The kit of parts includes a plasma generating device for use with a membrane dressing attached to tissue requiring treatment. The plasma generating device comprises a first cavity with an opening at one end formed between a grounded electrode and a cathode such that, in use, an arc discharge between the cathode and the grounded electrode ionizes a feed gas to produce at the open end a thermal plasma. Furthermore, the plasma generating device also comprises a second cavity with an opening at one end formed between a high voltage electrode and a grounded electrode such that, in use, a dielectric barrier discharge between the high voltage electrode and grounded electrode ionizes a feed gas to produce at the open end a non-thermal plasma.

Abstract: A plasma torch having an open end from which a plasma plume is emitted in use is disclosed. The plasma torch includes a central cathode rod, a grounded conductive tube having an open end and being arranged around the cathode and spaced therefrom to form a first cylindrical cavity open at one end; and a high voltage electrode having a dielectric barrier material at a radially inward-facing surface thereof and being arranged around the grounded conductive tube and spaced apart therefrom to form a second annular cylindrical cavity open at one end. A constant direct current (DC) electrical power plus a high voltage pulsed electrical power is provided to the cathode producing an arc discharge in the first cavity between the cathode and grounded tube to generate a central thermal plasma emitted at an open end of the first cylindrical cavity.
