Methods, devices, systems and kits for preparing compositions for care and repair of varicose veins

A method for preparing and extracting a foamed sclerosant composition comprising:

• providing a container having:
• a sealed container body for foaming comprising one or more sidewalls extending between a top and a bottom of the container body, a foaming space being defined in an interior of the container body, the foaming space containing a sterile gas and a mixing element configured to be operatively coupled with a rotatable actuator without the actuator entering into the foaming space, the interior of the container body being sterile, the container further including a female coupling member for mating with a syringe, and a pressure equalizer for equalizing a pressure inside the foaming space and a pressure outside the foaming space;
• the method further comprising:
• providing a syringe filled with a liquid sclerosant composition;
• mating the syringe with the female coupling member and injecting the liquid sclerosant composition into the foaming space through the female coupling member;
• operating the actuator to rotate the mixing element to create a foamed sclerosant composition in the foaming space;
• and
• extracting the obtained foamed sclerosant composition from the foaming space.
