Generation of therapeutic microfoam
First Claim
1. A method for producing a microfoam suitable for use in scleropathy of blood vessels, characterised in that it comprises introducing a physiologically acceptable blood-dispersible gas into a container 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.

13. A device for producing a microfoam suitable for use in scleropathy of blood vessels, comprising a housing in which is situated a pressurisable chamber containing a solution of the sclerosing agent in a physiologically acceptable solvent;
- a pathway with one or more outlet orifices by which the solution may pass from the pressurisable chamber to the exterior of the device through said one or more outlet orifices and a mechanism by which the pathway from the chamber to the exterior can be opened or closed such that, when the container is pressurised and the pathway is open, fluid will be forced along the pathway and through the one or more outlet orifices;
said housing incorporating an inlet for the admission of a pressurised source of physiologically acceptable gas that is dispersible in blood;
the gas being in contact with the solution on activation of the mechanism such as to produce a gas-solution mixture;
said pathway to the exterior of the housing including one or more foaming elements;
characterised in that the blood-dispersible gas is stored in a container provided with engaging means for the housing holding the aqueous sclerosant liquid. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 31, 32)
- a pathway with one or more outlet orifices by which the solution may pass from the pressurisable chamber to the exterior of the device through said one or more outlet orifices and a mechanism by which the pathway from the chamber to the exterior can be opened or closed such that, when the container is pressurised and the pathway is open, fluid will be forced along the pathway and through the one or more outlet orifices;

28. A device for producing a microfoam suitable for use in scleropathy of blood vessels, in the form of a kit comprising:
-
(a) a housing in which is situated a pressurisable chamber containing a solution of the sclerosing agent in a physiologically acceptable solvent;
a pathway with one or more outlet orifices by which the solution may pass from the pressurisable chamber to the exterior of the device through said one or more outlet orifices and a mechanism by which the pathway from the chamber to the exterior can be opened or closed such that, when the container is pressurised and the pathway is open, fluid will be forced along the pathway and through the one or more outlet orifices; and
(b) a pressurised container containing a physiologically acceptable blood-dispersible gas;
said housing incorporating an inlet for the admission of blood-dispersible gas;
the gas being in contact with the solution on activation of the mechanism such as to produce a gas-solution mixture. - View Dependent Claims (29, 30)
