  • Publication number: 20190216540
    Abstract: An ablation instrument (e.g., an ablation balloon catheter system) includes an elongate catheter having a housing with a window formed therein. An energy emitter is coupled to the elongate catheter and is configured to deliver ablative energy. A controller is received within the window and is coupled to the energy emitter such that axial movement of the controller within the window is translated to axial movement of the energy emitter and rotation of the controller within the window is translated into rotation of the energy emitter. The instrument includes a motor that is at least partially disposed within the housing of the catheter; a first gear that is operatively connected to and driven by the motor; and a second gear that is coupled to the energy emitter and is driven by the first gear to cause rotation of the energy emitter, while allowing the energy emitter to move axially.

  • Publication number: 20080063577
    Abstract: A sterilization and decontamination system in which a non-thermal plasma discharge device is disposed upstream of a suspension media (e.g., a filter, electrostatic precipitator, carbon bed). The plasma discharge device generates a plasma that is emitted through apertures (e.g., capillaries or slits) in the primary dielectric. Plasma generated active sterilizing species when exposed to contaminants or undesirable particulate matter is able to deactivate or reduce such matter in contaminated fluid stream and/or on objects. Thus, the undesirable contaminants in the fluid to be treated are first reduced during their exposure to the plasma generated active sterilizing species in the plasma region of the discharge device. Furthermore, the plasma generated active sterilizing species are carried downstream to suspension media and upon contact therewith deactivate the contaminants collected on the suspension media itself. Advantageously, the suspension media may be cleansed in situ.

  • Patent number: 7098420
    Abstract: A plasma emitter apparatus and method for using the same that includes a primary electrode and a secondary electrode. The secondary electrode is porous, that is, it is configured to permit the passage of plasma discharge therethrough. Accordingly, the plasma is received at one side of the secondary electrode and emitted from its opposing plasma exiting side. The secondary electrode may be a laminate of multiple insulating material layers with at least one conductive layer sandwiched therebetween. A plurality of apertures are defined through the laminate and a dielectric sleeve is inserted into and retained in the aperture. The generated plasma passes through one or more holes defined in each of the dielectric sleeves. Alternatively, the secondary electrode may be formed as a plurality of unidirectional high voltage wires strung substantially parallel across a frame or a plurality of bidirectional high voltage wires interwoven and secured by a perimeter frame.

  • Publication number: 20050205410
    Abstract: A capillary-in-ring gas discharge generator including an inner dielectric having a capillary defined therein, a primary electrode having a distal end partially inserted axially into the capillary of the inner dielectric, an outer dielectric disposed about the inner dielectric and separated therefrom so as to define a discharge zone therebetween; and a secondary electrode extending radially outward of at least a portion of the outer dielectric proximate the distal end of the primary electrode. Weakly ionized gas emissions occur out from the capillary and also in a discharge region between the inner and outer dielectrics. Thus, a weakly ionized gas plume is produced having a size substantially equal to that of the inner opening of the outer dielectric which is able to efficiently treat a relatively large surface area.

  • Publication number: 20050196315
    Abstract: A modular sterilization system including a modular sterilization section divided into a plurality of compartments. The system further includes a plurality of units, each unit being closable and received within one of the compartments of the modular sterilization section. A gas discharge generator is disposed in fluid communication with each unit to generate a weakly ionized gas that sterilizes the object(s) to be treated that are housed therein. Power is provided independently to only those compartments in which a corresponding unit has been properly installed. An electric field is thereby generated only in the generators of those units that have received power. As a result, the weakly ionized gas is emitted from the generator in which an electric field has been created in situ of an object to be treated.

  • Publication number: 20040050684
    Abstract: A system and method for the injection of an organic based reagent into weakly ionized gas to generate chemically active species. The organic based reagent may be a combination of an organic additive (e.g., an alcohol or ethylene) mixed with an oxidizer (e.g., oxygen) prior to being introduced in the weakly ionized gas. Alternatively, the organic based reagent may be the injection of an organic additive alone in the weakly ionized gas while in the presence of air (non vacuum chamber) that inherently contains oxygen and serves as the oxidizer. Also, the organic based reagent may comprise an organic additive that itself includes an oxidizing component such as EO. In this situation the oxidizing component of the organic component when injected into the weakly ionized gas forms hydroxyl radicals that may be a sufficient oxidizer to eliminate the need for a supplemental oxidizer.

  • Patent number: 6365112
    Abstract: Certain contaminants are removed from a stream of contaminant-laden commercial and industrial exhaust gases conducted through an electrostatic precipitator by passing a reagent fluid through corona discharge active zones to activate the reagent fluid as the reagent fluid is injected into the stream such that the activated reagent fluid reacts with the contaminant to be removed. A combination discharge electrode and injector carries a plurality of electrode elements which establish the corona discharge active zones and include injector passages juxtaposed with the corona discharge active zones. The reagent fluid is injected into the stream by delivering the reagent fluid through the injector passages such that the reagent fluid passes through the corona discharge active zones and is activated as the reagent fluid is injected into the stream.

  • Patent number: 6170668
    Abstract: A method of treating industrial gases to remove contaminants is disclosed. Ions are generated in stream of injectable gas. These ions are propelled through the contaminated gas as it flows through a collection unit. An electric field is applied to the contaminated gas. The field causes the ions to move through the contaminated gases, producing electrical charges on the contaminants. The electrically charged contaminants are then collected at one side of the electric field. The injectable gas is selected to produce ions which will produce reactions with particular contaminants. The process is thus capable of removing particular contaminants. The process does not depend on diffusion as a transport mechanism and is therefore suitable for removing contaminants which exist in very low concentrations.
