  • Publication number: 20080145401
    Abstract: Improved therapeutic sclerosing microfoams and methods and devices for making them are provided that have advantage in producing a consistent profile injectable foam with minimal input by the physician yet using high volume percentages of blood dispersible gases, thus avoiding use of potentially hazardous amounts of nitrogen.

  • Publication number: 20080138376
    Abstract: A device is described for facilitating the preparation of therapeutic foam e.g. for the treatment of varicose veins. A pressurised vial contains a sclerosant liquid, e.g., polidocanol solution, and a sterile gas which is readily absorbed by the body, e.g., carbon dioxide, oxygen or a mixture of these gases. The vial is provided either with a specialised stopper/seal into which a syringe nozzle may be inserted or alternatively a septum seal which may be penetrated by a hypodermic needle. The quantities of gas and liquid and the pressure in the vial are pre-set so that, on connection of a syringe to the vial, a predetermined volume of both gas and liquid is transferred to the syringe, with the intention that the syringe is then used to make a foam by known means. The use of the vial ensures that the ratio of gas to liquid in the foam is standardized, and also provides a convenient way of packaging the gas and liquid and of filling the syringe in a sterile manner.

  • Publication number: 20040156915
    Abstract: A method for producing a microfoam suitable for use in scleropathy of blood vessels comprises introducing a physiologically acceptable blood-dispersible gas into a container (1) holding an aqueous sclerosant liquid and releasing the mixture of blood-dispersible gas and sclerosant liquid, whereby upon release of the mixture the components of the mixture interact to form a microfoam.

  • Patent number: 6713659
    Abstract: Self-adhesive bandage consisting of a flexible carrier with a self-adhesive coating applied on one side, characterized in that the carrier is provided with a large number of apertures, thus giving rise to individual segments linked by way of connecting bridges.

  • Patent number: 6687999
    Abstract: A construction of ink dispensing roller is described in which a porous ink metering layer extends around a peripheral surface of a porous ink reservoir. To prevent relative movement between the ink metering layer and the ink reservoir, the ink metering layer is securely located relative to the ink reservoir by means of elements of the ink metering layer extending beyond each axial end of the ink reservoir and being clamped between end cheeks and the axial end walls of the ink reservoir. The ink metering layer is manufactured from sheet material joined by welding along opposite edges into a tubular form. After welding the tubular form is manipulated so that an inner surface becomes a radially exterior ink dispensing surface.
