To obviate the problems which occur after a treatment of a stenosis by means of the usual dotter treatment followed by the placing of a stent which delivers a medically active substance, the invention proposes an implant assembly, to be fixed in a body vessel, with a section to be directed in the direction of the vessel axis and provided with means to act from therefrom on the surrounding tissue, in which this section, which can be fixed with at least one end by means of an anchoring element to the vessel wall, has a non-rigid structure, in such a way that it can adapt itself to the vessel wall configuration without any appreciable radial pressure on the surrounding tissue. Thus the surrounding tissue is not subjected to undesired pressures and resulting into a rapid recovery, without the formation of new tissue.
