Abstract

Improved therapeutic sclerosing microfoams and methods and devices for making them are provided that have advantage in producing a consistent profile injectable foam with minimal input by the physician yet using high volume percentages of blood dispersible gases, thus avoiding use of potentially hazardous amounts of nitrogen.

Claims (2)

1 . A method for producing a microfoam suitable for use in sclerotherapy of blood vessels characterised in that it comprises passing a mixture of a physiologically acceptable blood dispersible gas and an aqueous sclerosant liquid through one or more passages having at least one cross-sectional dimension of from 0.1 to 30 μm the ratio of gas to liquid being controlled such that a microfoam is produced having a density of between 0.07 g/ml to 0.19 g/ml and has a half-life of at least 2 minutes.
