Patent number: RE40640Abstract: Injectable microfoam for scleroteraphy. The sclerotherapy of varices is based on the injection of liquid substances capable of suppressing them. The present invention relates to the preparation of sclerosing substances in the form of a microfoam. The microfoam is prepared with sclerosing agents, and is then injected in the vein to be treated, so that the microfoam displaces the blood contained in the vein and provides for the contact of the sclerosing agent with the vascular endothelium, with a predetermined known concentration and during a controllable time.Type: GrantFiled: September 15, 2004Date of Patent: February 17, 2009Assignee: BTG International Ltd.Inventors: Juan Cabrera Garrido, Juan Cabrera Garcia-Olmedo
