Abstract:
Eine Austragvorrichtung zum Austragen eines fluiden Produkts umfasst ein Gehäuse (1) mit einem Auslass (6) an einem vorderen Gehäuseende, ein beweglich in dem Gehäuse gelagertes Austragglied (3), das mit seinem hinteren Ende aus dem hinteren Gehäuseende ragt, und eine Mischeinrichtung (2) zum Mischen des fluiden Produkts innerhalb des Gehäuses. Das fluide Produkt ist in einem zwischen dem Auslass und dem Austragglied ausgebildeten Gehäusevolumen (25) vorgesehen. Durch Vorschub des Austragglieds innerhalb des Gehäuses von einer hinteren Stellung in eine vordere Stellung in Richtung des Auslasses wird das fluide Produkt durch den Auslass aus dem Gehäuse ausgetragen. Die Mischeinrichtung weist ein Mischrohr (11), das zwischen dem Gehäuse und dem Austragglied beweglich im Gehäuse gelagert ist, und wenigstens ein Mischelement (12) auf, das am vorderen Ende des Mischrohres vorgesehen ist und innerhalb des Gehäusevolumens angeordnet ist.
Abstract:
A system includes a source (102) of at least a first component, and a mixer (104) having an inlet (106) coupled to the source of at least a first component and an outlet (108), the mixer including at least one mixing device and a source (144) of at least a second component disposed between the inlet and the outlet. The at least one mixing device includes a three-dimensional lattice defining a plurality of tortuous, interconnecting passages therethrough. The at least one mixing device has physical characteristics to sufficiently mix the first and second components, which characteristics include a selected one or more of mean flow pore size, thickness and porosity. Also disclosed are a kit defined by the source and the mixer, in the form of a mixer adapter, and the mixer adapter alone.
Abstract:
A fibrin wound dressing is made by mixing quantities of fibrinogen solution and thrombin solution with air. The resulting foam is very light weight, and with the proper attention to the amount of thrombin, is also sufficiently viscous to rest on a vertical surface without dripping. The wound dressing may also be formulated for its ability to continue migration of healing substances, such as PDGF, from the dressing to the wound site. Thrombin substitutes, such as other clotting proteins, may be used instead of thrombin. The resulting foam may also be lyophilized or ground and lyophilized for later reconstitution. A therapeutic drug or other additive may also be added to the wound dressing.
Abstract:
Medical apparatus and processes controllably generate medically useful micro or nano bubbles of medically desirable and controllably selectable size, size distribution, homogeneity and concentration (and/or other key bubble parameters) for patient infusion, and/or which may incorporate therapeutic or other agents for patient infusion and/or may be combined with therapeutic or other agents prior to infusion into patients. The bubble generation apparatus and processes controllably permit the adjustment and selection of key bubble parameters through bubble generation actuation and orientation techniques and through selection of bubble fluid compositions in order to facilitate medical research and/or to optimize treatment for imaging, therapy, sonoporation, inertial and non-inertial cavitation, and acoustic activation, among other medical uses. Disposable cartridges containing such bubbles are provided and may include means for patient infusion.

Abstract:
Bone cement mixing systems and related methods are disclosed. The bone cement mixing systems can include a first chamber, a second chamber, and a passage fluidly connecting the first and second chambers. A first piston can be disposed in the first chamber, and a second piston can be disposed in the second chamber.
Abstract:
A foam comprising a liquid phase and a gas phase wherein the liquid phase comprises at least one sclerosing agent and is at least 20% vol/vol of at least one viscosity enhancing agent and the gas phase comprises at least 50% CO2 and wherein the foam has a density less than 0.25 g/ml and half life of greater than 100 secs. A further case where the viscosity is ranging from 2.0-3.5cP. Methods of producing such foam. Devices for producing such foams.
Abstract:
The present invention provides for a topical composition that includes a topical carrier and an adenosine deaminase inhibitor. Suitable specific adenosine deaminase inhibitors include, e.g., deoxycoformycin (dCF), deoxyadenosine (dAdo), cladrabine (CdA), fludarabine (F-Ara-A), cytrabine (Ara-C), and thioguanine. The present invention also provides for a method to treat lymphocyte mediated skin diseases and to alleviate symptoms associated with such skin diseases. The method includes topically administering the composition to a mammal in need of such treatment. The present invention also provides for kits and syringe systems that include the adenosine deaminase inhibitor.
Abstract:
A therapeutic foam for the treatment of, inter alia, varicose veins comprises a sclerosing solution foamed with a physiological gas such as carbon dioxide, oxygen or a mixture thereof. The foam has a nitrogen content of less than 0.8 %. It may be generated using a pressurised canister system incorporating a fine mesh of micron dimensions through which the gas and sclerosing liquid are passed to make the foam. Alternativelt, the foam may be generated by passing gas and solution between two syringes through a fine mesh. Techniques are described for minimising the amount of nitrogen in a canister or syringe based product. A technique for generating and delivering foam simultaneously using a syringe based device is also disclosed.
Abstract:
Die Anordnung für Transfer, Mischen und Austragen umfasst vorzugsweise mindestens zwei Austragvorrichtungen (1, 2). Eine Austragvorrichtung (2) weist flüssige Komponenten (21, 23) auf und die Anordnung enthält eine Transfereinheit (15) zum Anschluss der Austragvorrichtungen (1, 2) und die Transfereinheit weist Verbindungskanäle (36, 38) zwischen Auslässen (17, 18; 41,42) für die Komponenten (21, 23; 22, 24) in den Vorratsbehälter (5, 6; 7, 8) der Austragvorrichtungen (1, 2) auf. Zwecks Erhöhung der Betriebssicherheit weist die Transfereinheit (15, 31, 39) Verriegelungselemente (36) zur Aufnahme von entprechenden Flanschen (19, 20) an den Austragvorrichtungen (1, 2) auf. Ein solches Spritzen-System erlaubt, unter Verwendung von Doppelspritzen, das problemlose Lagern und das leichte und gute Vermischen mehrerer Komponenten sowie das einfache Austragen der Gemische. Eine solche Anordnung weist besondere Vorteile auf, falls in der ersten Spritze Pulver oder Granulat, z. B. Knochenzement oder Knochenersatzstoff vorhanden ist.
