Intraluminal vascular device, particularly for sclerotherapy, and method

A vascular device for treating at least one tract of a blood vessel, comprising:

• an intraluminal element comprising at least one dispensing opening for dispensing a pharmacological agent in the at least one tract of the blood vessel;
• 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 to remove material treated with the pharmacological agent from said inner wall,
• wherein said abrasion element comprises a contact portion adapted to obtain removal of the material from said inner wall, and wherein said abrasion element comprises a collection portion for collecting the 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 a longitudinal extension direction of the blood 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 facing said intraluminal element and configured to face a fluid inside the blood vessel,
• wherein said first surface, in said at least one contact configuration, forms a concave portion adapted to face the fluid inside the blood vessel, and 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 a portion of the intraluminal element to which said first surface faces,
• wherein between said at least one contact configuration and said at least one 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 dispensing opening.
