Abstract:
Exemplary systems and methods associated with skin treatments using non- thermal plasma to porate skin or tissues using conductive elements to direct an electric field through targeted regions of the skin or tissue. Various configurations of conductive elements and associated circuitry may be used to tune and control the electric field.
Abstract:
Exemplary apparatuses and methods of killing or deactivating bacteria are disclosed herein. An exemplary apparatus for killing or deactivating bacteria includes a plasma vapor chamber. The plasma vapor chamber has a vapor inlet for allowing a vapor into the chamber, a high voltage electrode, one or more grounding electrodes. The one or more grounding electrodes at least partially surrounding the plasma vapor chamber. The plasma vapor chamber includes an outlet for allowing fluid to flow out of the chamber. When the chamber is filled with vapor for a period of time sufficient to saturate the chamber with vapor, the high voltage electrode is energized to generate plasma throughout the chamber.
Abstract:
A medical device for directly applying DBD plasma includes a plasma generation module having an electrode surrounded by a dielectric barrier. In one embodiment, when a high voltage source is applied to the electrode, plasma is produced from ambient gas on an outside surface of the plasma generation module. In another embodiment, an enclosure is deployed around the distal end of the plasma generation module surrounding the electrode. Gas flows past the electrode and into the enclosure. In some embodiments, some or all of the gas is removed or pumped out of the enclosure by suction/vacuum. When a high voltage source is applied to the electrode, plasma is produced using the gas flowing into the enclosure.
Abstract:
A treated crop plant or plant food product with decreased bacterial viability relative to an untreated crop plant or plant food product. The treated crop plant or plant food product has at least a 1-log reduction in bacterial viability relative to the untreated crop plant or plant food product. Methods and apparatuses of producing the treated crop plant or plant food product are also provided.
Abstract:
Exemplary embodiments of shape conforming dielectric barrier discharge (DBD) plasma generators are disclosed herein. One exemplary embodiment includes a flexible pad and a plurality of electrodes located in the pad within close proximity of each other, and a flexible dielectric barrier surrounding the plurality of electrodes and separating the plurality of electrodes from each other. Wherein when a high voltage pulse is applied to one or more of the plurality of electrodes, plasma is produced between a surface of the flexible pad and a portion of the body in close proximity to the flexible pad.
Abstract:
Exemplary methods for killing or deactivating bacteria are provided herein. One exemplary method includes providing a plasma system and a filter below the plasma system. Energizing the plasma generator to create indirect plasma downstream of the filter and activating a fluid with the indirect plasma and applying the activated fluid to bacteria is shown to deactivate and kill bacteria.
Abstract:
Exemplary systems and methods associated with trans-tissue substance delivery using non-thermal plasma to porate skin or tissues using contoured dielectrics/electrodes and grounding techniques. In some embodiments, a substance delivery system may be incorporated into the plasma generating device for automatically controlled skin treatments. In other embodiments, a skin treatment patch may include the electrode and the treatment substance.
Abstract:
Exemplary methods of treating tissue that has been harvested for transplant are disclosed herein. An exemplary method of preparing corneal tissue for transplant includes obtaining corneal tissue that has been harvested for transplanting and exposing the corneal tissue to a plasma-activated fluid for a period of time.
Abstract:
Exemplary methods and systems for killing or deactivating spores include applying a fluid containing an additive to a surface containing a spore; and applying direct or indirect plasma to the surface for a period of time.
Abstract:
Exemplary methods of opening pores and moving molecules into tissue comprising, applying plasma to the surface of tissue and applying a carrier including one or more molecules to the surface of the tissue are disclosed herein.
