Zusammenfassung:Device containing sclerosant liquid for use in the treatment of blood vessels having an aerosol valve housing containing gas-entry ports. The aerosol valve housing is mounted on a canister having an expandable inner container in which the sclerosant fluid is contained. The expandable inner container is affixed to the outer opening of the canister or to the aerosol valve housing above the valve gas-entry ports so that gas taken from the interior of the expandable inner container can mix with the sclerosant liquid to create a micro foam, such that introduction of pressurized gas through the aerosol valve causes the expandable inner container to inflate to accommodate the pressurized gas.
