Abstract

A system for treating extensive obliterative vascular diseases, in which the severity of the disease is different in different vascular sections, comprises: one or more biocorrodible stents arranged with a distance between them in sections of the diseased vessel that have been dilated by transluminal angioplasty, and a device adapted for release of an active ingredient in the lumen or in the vascular tissue, designed (i) to release the active ingredient in the lumen of the diseased vessel, whereby the active ingredient is released in a vascular section at the greatest distance proximally in the direction of blood flow in the vessel; or (ii) to release the active ingredient in the vascular tissue whereby the active ingredient is released in one or more vascular sections of the vessel to be treated so that the active ingredient can spread throughout the area of the diseased vessel through diffusion.
