ABSTRACT:
In a sleeve catheter for supplying medicine to the walls of a vessel or tubular organ in which a number of outer lumina extend longitudinally around a central lumen, the outer lumina have radial discharge openings in the area of the head portion of the catheter, which is slidable onto a balloon catheter in order to be disposed at least partially on the balloon of the balloon catheter so as to be expandable thereby into abutment with the inner wall of a vessel to be dilated whereby medicine can be supplied through the discharge openings in the outer lumina under pressure directly to the tissue of the vessel adjacent the outer lumina, thereby applying the medicine solely to the area engaged by the outer surface of the head portion.
