US Classification:

606 49

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.

Abstract:

The present invention is direct to a nano-probe corona tool and uses thereof. A nano-probe corona tool is disclosed having a tip with a diameter in the nano-scale, typically around 100 nm. The nano-probe corona tool is constructed of electrically conductive material. On the other end of the tool, a pulsed voltage source outputs a pulsed voltage to generated a pulsed electrical potential at the tip. The pulsed electrical potential at the tip causes a plasma discharge corona to occur. Uses of the corona discharge include, but are not limited to, optical emission spectroscopy, in the enhancement of deposition of coatings and nanoscale welding, e.g., nanotube or nanowires to a contact pad and welding two nanowires together, and in nanoscale surgery. For example, a nano-probe comprising CNTs may be inserted into cell membranes. The resulting corona discharge may be used to destroy tumors within the cell.

US Classification:

435 2, 422186, 422 29, 606 33

Abstract:

Disclosed is a device and method for contacting a biological substrate. A non-thermal plasma device delivers a non-thermal plasma discharge using a dielectric conduit, an igniter electrode and a RF electrode. The dielectric conduit fluidicly communicates a gas therethrough and an igniter electrode ionizes at least a portion of the gas. The RF electrode, disposed circumferentially proximate to the exterior of the dielectric conduit, generates non-thermal plasma from the ionized gas. The non-thermal plasma is discharged from the dielectric conduit and contacts a biological substrate. The non-thermal plasma discharge may be suitable for tissue bonding and sterilization applications.

International Classification:

A61M 37/00

US Classification:

604 24

Abstract:

A method and apparatus for depositing a film on a biological substrate are provided. A plasma generation device includes a dielectric conduit and a high voltage electrode. The plasma generation device is placed in proximity to the biological substrate and a gas supply that includes a precursor material is directed through the dielectric conduit. An electric field generated by the potential difference between the high voltage electrode and the biological substrate ionizes at least a portion of the gas supply and causes plasma to emanate from the dielectric conduit and contact the biological substrate. The plasma induces a reaction of the precursor material to form a film that is deposited on the biological substrate.

US Classification:

208 14, 42218604, 204172

Abstract:

Provided herewith is a novel method of controllably processing a dielectric fluid by creating discharges within the dielectric fluid from mobile charge carriers contained within the dielectric fluid. Generally, the dielectric fluid and the mobile charge carriers are between two electrodes which apply a voltage to the charge carriers. In one embodiment, the dielectric fluid is a hydrocarbon fluid such as a heavy crude oil or a fuel. In one embodiment the charge carrier comprises water droplets. In another embodiment, the mobile charge carriers are metallic balls. In both instances the discharges initiate from the mobile charge carriers.

F23Q 5/00

Abstract:

Provided is an approach for scaling up a multiphase plasma chemical reactor that uses gas bubble discharge in liquids. One example involves single spark gap discharge scale up systems and processes with suitable characteristic parameters. Scaling parameters are based on the size change of one spark gap. Another example involves scale-up systems and processes that can be applied to multiple spark gaps with multiple discharge modules and its dimension information. Numbers of modules and resulting device sizes could be based on required production rate and specific energy input. Applications allow for scaling up of any plasma chemical system or process with similar mechanisms and reactors, such oil treatment reactors.
