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.
L'invention concerne un procédé de traitement non thermique de tissu humain ou animal au moyen de plasma de décharge électrique haute tension. Selon ce procédé, un courant traverse un plasma et un tissu, non pas pour chauffer le tissu, mais pour maintenir le plasma à proximité du tissu en cours de traitement. L'invention porte également sur un procédé pour limiter le courant traversant le plasma et le tissu, afin de minimiser l'échauffement du tissu au moyen d'un isolant ou d'un semi-conducteur placé entre une électrode et le tissu, d'où la génération d'une décharge haute tension similaire à une décharge à barrière diélectrique. Le traitement par plasma non thermique de l'invention peut être appliqué pour favoriser la coagulation sanguine, la stérilisation, la désinfection, le raccordement de tissu et le traitement de troubles tissulaires sans causer de dommage thermique significatif au tissu.
