The present invention provides a medical vascular stent that the support force in the diametrical direction is large, and the stent is hardly depressed during expansion in the diametrical direction, and the lumen wall is little stimulated during expansion, and the stent is not contracted in the axial direction. The medical vascular stent is a medical stent formed in a tubular shape by a metallic string net, and the metallic string net is structured so that a plurality of star-shaped cells 11 to 14 mutually connected in the circumferential direction are set as a net unit in the axial direction and a plurality of such units 15 to 21 are arranged in the axial direction, and the net units in the axial direction are mutually connected by connection of the respective star-shaped cells, constituting the net units in the neighboring axial directions, in the axial direction.
A medical vascular stent formed in a tubular shape with a metallic string net, wherein the metallic string net has a structure that a plurality of star-shaped cells are interconnected along a circumferential direction forming a axial net unit in the string net, and that a plurality of such axial net units are arranged in the axial direction, wherein the axial net units are mutually interconnected with each other along an axial directions of the stent by connecting the respective star-shaped cells with each other included in the neighboring axial net units.
A medical vascular stent formed by a metallic string net in a tubular shape, wherein said metallic string net has a plurality of metallic strings in a substantially sine wave-form arranged in parallel in the axial direction and extended in the circumferential direction of said tube and in which a plurality of curved metallic strings with a single peak arranged in the circumferential direction of said tube so as to mutually interconnect said neighboring sine wave-form metallic strings at neutral points of wave lengths forming said sine waves, wherein said curved metallic strings with a single peak are arranged so that the directions of the peaks of said neighboring curved metallic strings in the axial direction are opposite to each other.
