Abstract

The use of non-thermal plasma to treat mucus membrane bleeding is described herein. A non-thermal plasma is generated using an apparatus having a first electrode that receives alternating electrical potentials from a power supply. When placed in an appropriate location proximate to tissue, a non-thermal plasma is generated, the second electrode being human tissue, blood, etc. To reduce the likelihood of an arc being generated, potentially causing tissue damage or pain, the first electrode is partially encapsulated by a dielectric. The non-thermal plasma is applied to the area of bleeding for treatment.
