    摘要: A method for preparing cold atmospheric plasma stimulated cell culture media with a cold atmospheric plasma system having a delivery port out of which an inert gas flows. The inert gas may be helium. The method comprises the steps of placing a cell culture media in a first well, the first well having a bottom and having a diameter greater than 20 mm; wherein the cell culture media placed in the first well has a volume of 4 ml or less, treating the cell culture media in the first well with cold atmospheric plasma, wherein the treating is performed with a gap between the delivery port and the bottom of the first well is between 2.5 cm and 3.5 cm, and transferring a portion of the treated media to cultured cancer cells in a second well. The cold atmospheric plasma may be applied for 0.5 minutes to 2 minutes.

    摘要: In a preferred embodiment, the present invention is a plasma sealer attachment for an electrosurgical system. The attachment has a connector assembly, a cable, and a hand piece. The hand piece has a splitter, a pair of tubes and a pair of conductive wires. When used, an inert gas flows through the connector assembly, down the cable and out both tubes. One of the conductive wires is connected to a source of monopolar electrosurgical energy and acts as an active electrode. The other conductive wire is connected to a neutral or ground and acts as a return electrode.
