Lesion specific stents, also for ostial lesions, and methods of application

摘要

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 Ieast two different stent characteristcs as needed for optimal stent treatment. The main portion (30) is predominantly plastically deformable and at least one end portion (20) 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.
