20080274060 | Therapeutic Foam - A foam is described for injection treatment of varicose veins. The foam comprises a sclerosant liquid, e.g. polidocanol solution, and a gas. The gas comprises xenon, optionally together with at least one other physiologically acceptable gas which is readily absorbed in the body or blood of a patient. The gas comprises only a minimal amount of gaseous nitrogen, between 0.0001% and 0.8%. | 11-06-2008 |
20090148490 | Preparation of Therapeutic Foam - 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. | 06-11-2009 |
20100099778 | DEVICE AND METHOD FOR PRODUCING THERAPEUTIC FOAM - A device and a method for generating therapeutic foam from a sclerosing solution such as polidocanol and a gas which is absorbable or dissolvable in the body comprises a disposable cassette including a liquid container and a flexible chamber containing gas, chamber being formed as a loop. Located in the loop chamber is a foam generating mesh. In use, liquid is introduced into the chamber and then the cassette is inserted into a pumping machine where it is engaged by a peristaltic pump which circulates the contents of the loop chamber through the mesh, thus creating foam. When a steady state is reached, foam may be withdrawn using a syringe via either a port or septum. | 04-22-2010 |
20100260007 | Preparation of therapeutic foam - Closed pouch comprising a wall defining an enclosed space containing carbon dioxide, and a pair of syringes contained within the enclosed space. The syringes are connected together by a syringe connector, and of the syringes contains a gas or gas mixture other than air, while the other contains a foamable liquid. Breakage of the syringe, connector and pumping of the syringes produces a foam useful in the treatment of varicose veins. | 10-14-2010 |
