Claim 0:
1. A method of sclerosing treatment of a blood vessel comprising the steps of:
isolating a residual volume of an initial volume of a blood vessel to be treated from blood circulation, wherein said residual volume contacts an inner wall of the blood vessel, wherein the residual volume is standardized independently from an initial volume of the blood vessel;
injecting a sclerosing drug in said residual volume;
standardizing the sclerosing treatment through control of the following variables:
dilution of the sclerosing drug caused by the blood flow,
contact time of the sclerosing drug with the blood vessel wall having an endothelium,
contact of the sclerosing drug with the endothelium of a whole circumference of a section of the blood vessel, and
concentration of the sclerosing drug;
wherein the method is carried out by a catheter;
wherein the step of isolating defines the residual volume as a closed volume by at least two spherical balloon elements axially spaced, and wherein the residual volume is standardized by an elongated balloon interposed between the at least two spherical balloon elements, wherein the elongated balloon is configured to be inflated changing a dimension of the elongated balloon substantially only in a transverse direction, maintaining substantially a same axial dimension, wherein, in dependence of an inflation degree of the elongated balloon, the residual volume is restricted always to a same standard volume between the at least two spherical balloon elements the at least one elongated balloon and the inner wall of the blood vessel independently from initial dimensions of the isolated blood vessel.
