Abstract: 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.

Abstract: A hinge strip for double-action glass doors, with a fixed hinge portion, a door hinge portion pivotable about the fixed hinge portion, a pivoting axis penetrating the fixed hinge portion and the door hinge portion, a cam with at least one depression disposed at the axis, and a force-loaded roller that cooperates with the cam. To achieve a precise adjustment of the zero position of the door, the roller is disposed to be adjustable orthogonally with regard to the longitudinal axis of the hinge strip.

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 When a steady state is reached, foam may be withdrawn using a syringe via either a port or septum.

Abstract: 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%.
