    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 pressurized 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 minimizing 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 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 When a steady state is reached, foam may be withdrawn using a syringe via either a port or septum.
