Abstract:
The present invention relates to a canister device that is suitable for producing sclerosing foam for intravenous injection, in the treatment of varicose veins and other venous disorders. The canister device for producing therapeutic foam, the device comprises a pressurisable chamber containing sclerosant liquid and physiologically acceptable gas; a foam pathway through which the liquid and the gas may pass from the chamber to the exterior of the device, the pathway including a gas-liquid interface at which the liquid and the gas are mixed and foam is formed; and a mechanism by which the pathway can be opened or closed, such that, when the chamber is pressurised and the pathway is open, the liquid and the gas are forced to pass along the pathway to the exterior of the device; characterised in that an expandable compartment is located within the chamber, the compartment comprising an internal space that is in fluid communication with the exterior of the device through a fluid inlet located on the exterior of the device and that is not in fluid communication with the liquid or the gas, wherein in use fluid is introduced through the fluid inlet to expand the compartment and pressurize the chamber. The device is only pressurized at the point of use and therefore avoid problems associated with shipment and storage of pressurized medical grade gases.

Claim (Index 13):
A canister device according to  claim 2 , further comprising a pressure indicator to inform a user when the chamber is pressurized to a desired level.
