Abstract
Method for producing a microfoam suitable for use in scleropathy of blood vessels by introducing a physiologically acceptable blood-dispersible gas into a container holding an aqueous sclerosant liquid and releasing the mixture of blood-dispersible gas and sclerosant liquid such that, upon release of the mixture, the components of the mixture interact to form a microfoam. The container is provided with a steam-sterilizable aerosol valve having a valve body of polymeric material having an HDT (heat deflection temperature) at 1.8 MPa stress in the range of 200-275 ° C.
