Abstract
A nozzle for attachment to a cold plasma device configured to maintain delivery of a stable cold plasma. The nozzle can have many different shaped apertures to support different applications requiring different shaped cold plasma plumes. Use of a disc of foam material within a nozzle can expand the size of aperture of a nozzle while maintaining delivery of a stable cold plasma. The nozzle can be an elongated cannula tube for internal delivery of a cold plasma treatment. The cannula tube can provide an aperture at its distal end or one or more apertures along its length. A shroud can partially enclose the distal aperture of the nozzle. A sterile sleeve can be used in conjunction with a nozzle to provide a sterile means of attachment and operation of the nozzle with a cold plasma device.
