US Patent 9472382 Cold plasma annular array methods and apparatus

Methods and apparatus are described that use an array of two or more cold plasma jet ports oriented to converge at a treatment area. The use of an array permits greater tissue penetration by cold plasma treatments. This approach enables treatment of deeper infections of soft and hard tissues without surgical intervention. For example, this approach can treat sub-integumental infections, such as those common to joint replacements, without surgically opening the issues overlying the deeper infection.
