    摘要： 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. Alternatively, 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.

    摘要： A foam transfer device (600) is described, for use with aerosol canister apparatus for producing a sclerosant foam for the treatment of, inter alia, varicose veins. The device enables diversion of an initial quantity of below-specification foam from the canister to waste, e.g. to an integral waste chamber, before dispensing a further quantity of foam for use in treatment. The switching of the flow from the waste chamber to a different outlet (618) for use is accomplished without interrupting the flow from the aerosol canister since this would cause the foam to drop below specification again. The waste chamber may be transparent so that the foam entering it can be observed and a decision made by a user when to stop diverting foam to waste. Alternatively, the foam may be diverted automatically e.g. when a set time has elapsed or a set volume of foam dispensed. The foam for use is normally dispensed into a syringe for subsequent injection into a varicose vein of a patient.

    摘要： A sclerosing foam comprising a physiologically acceptable gas that is readily dispersible in blood together with an aqueous sclerosant liquid is a microfoam further including one or more detectable gases selected from helium, neon, xenon, argon, sulfur hexafluoride and nitrous oxide, where the total volume of detectable gases comprises from 0.01% to 40% of the total volume of gas.
