阅读说明：本技术 医疗装置，特别是支架 (Medical device, in particular stent ) 是由 乔尔吉奥·卡塔内奥 安德烈亚斯·舒斯勒尔 于 2019-12-11 设计创作，主要内容包括：本发明涉及一种医疗装置,特别是支架,具有至少部分为管状的、可径向自扩展的网格结构(10),该网格结构(10)由自身交织的单根线材(11)构成,该线材(11)具有射线不可透过的芯材料(11a)和超弹性的护套材料(11b),并形成网格结构(10)的网眼(12)。本发明的特征在于,在网格结构(10)的圆周方向上直接相邻的多个网眼(12)形成网眼圈(13),其中在完全自扩展状态下的网格结构(10)具有扩展直径D-(exp),网眼圈(13)具有网眼数量n,芯材料(11a)具有芯直径d-(Kern),并且其中对于芯直径d-(Kern)适用：d-(Kern)＝f·(D-(exp)/n),其中对于可见性因子f适用：0.05≤f≤0.08。(The invention relates to a medical device, in particular a stent, having an at least partially tubular, radially self-expandable lattice structure (10), the lattice structure (10) being formed from individual wires (11) which are interwoven with one another, the wires (11) having a radiopaque core material (11a) and a superelastic sheath material (11b) and forming meshes (12) of the lattice structure (10). The invention is characterized in that a plurality of meshes (12) directly adjacent in the circumferential direction of the lattice structure (10) form an eyelet (13) which is formed by a plurality of meshes (12)Wherein the lattice structure (10) in a fully self-expanding state has an expanded diameter D exp The mesh loops (13) have a mesh number n, and the core material (11a) has a core diameter d Kern And wherein for the core diameter d Kern The method is applicable to the following steps: d Kern ＝f·(D exp N), where for the visibility factor f: f is more than or equal to 0.05 and less than or equal to 0.08.)
