Implantable bio-resorbable vessel-wall-support consists of a framework of interconnected arms with different cross-sections, thicknesses and widths

摘要

The support, made of bio-resorbable polymeric or metal material, is formed by a framework of interconnected arms (2,2',3,4,5). The resorption time of the arms at different parts of the supports varies with the different cross-sections, width and thicknesses of the arms and are produced by perforations in the arms. The cross-section surfaces of the arms are obtained by the framework elements providing the radial strength of the vessel wall support are more slowly resorbable than the supporting framework providing axial strength.
