Abstract

A balloon or dilatation activated stent particularly for use in a body vessel for specific lesions, particularly in the region of the ostium of a vessel or a bifurcation featuring at least two different stent characteristics (20, 30) as needed for optimal stent treatment. The main portion is predominantly plastically deformable and at least one end portion is elastically deformable and opens to a diameter significantly larger than the diameter of the main portion thereby covering the area of a vessel bifurcation or the ostium and the adjacent vessel wall by conforming to it. The second stent is protruding axially from at least one end (proximal and/or distal) of the first stent. At least one protruding end of the stent assembly is comprised of predominantly self-expanding elastically deformable stent material of shape-memory material forming a flaring end of the protruding end of the stent defining a stent section lying essentially in a surface running perpendicular or obliquely to the longitudinal axis of the remainder of the stent assembly.
