A vascular device for treating at least one blood vessel tract comprising: - an intraluminal element having at least one opening for dispensing a pharmacological agent in the blood vessel tract; and - at least one abrasion element connected to the intraluminal element and adapted to come into contact with an inner wall of the blood vessel tract to remove material treated with the pharmacological agent from said inner wall; wherein said abrasion element comprises at least one contact portion adapted to obtain the removal of the material from said inner wall, and wherein said abrasion element comprises at least one collection portion for collecting material removed from said inner wall, wherein said abrasion element is configured to expand with respect to said intraluminal element at least in a radial direction transverse to the longitudinal extension direction of the vessel between at least one rest configuration and at least one contact configuration, wherein, in said at least one contact configuration, said contact portion is in contact with the inner wall, and, in said at least one rest configuration, the contact portion is spaced from the inner wall, wherein said abrasion element comprises at least a first surface (17, 23) facing said intraluminal element and configured to face a fluid inside the blood vessel, wherein said at least a first surface (17, 23), at least in said contact configuration, forms a concave portion adapted to face the fluid inside the blood vessel, wherein said collection portion comprises said concave portion so as to collect the material removed from the inner wall treated with the pharmacological agent, wherein said collection portion forms an annular collection chamber around the portion of intraluminal element to which said first surface (17, 23) faces, wherein between said contact configuration and said rest configuration, said contact portion approaches said intraluminal element closing said concave portion towards said intraluminal element so as to retain the removed material, and wherein said concave portion has a concavity facing the at least one drug dispensing opening. - an intraluminal element having at least one opening for dispensing a pharmacological agent in the blood vessel tract; and - at least one abrasion element connected to the intraluminal element and adapted to come into contact with an inner wall of the blood vessel tract to remove material treated with the pharmacological agent from said inner wall; wherein said abrasion element comprises at least one contact portion adapted to obtain the removal of the material from said inner wall, and wherein said abrasion element comprises at least one collection portion for collecting material removed from said inner wall, wherein said abrasion element is configured to expand with respect to said intraluminal element at least in a radial direction transverse to the longitudinal extension direction of the vessel between at least one rest configuration and at least one contact configuration, wherein, in said at least one contact configuration, said contact portion is in contact with the inner wall, and, in said at least one rest configuration, the contact portion is spaced from the inner wall, wherein said abrasion element comprises at least a first surface (17, 23) facing said intraluminal element and configured to face a fluid inside the blood vessel, wherein said at least a first surface (17, 23), at least in said contact configuration, forms a concave portion adapted to face the fluid inside the blood vessel, wherein said collection portion comprises said concave portion so as to collect the material removed from the inner wall treated with the pharmacological agent, wherein said collection portion forms an annular collection chamber around the portion of intraluminal element to which said first surface (17, 23) faces, wherein between said contact configuration and said rest configuration, said contact portion approaches said intraluminal element closing said concave portion towards said intraluminal element so as to retain the removed material, and wherein said concave portion has a concavity facing the at least one drug dispensing opening.
