The present invention relates to an intravascular device having an undulating pattern consisting of struts and loops. In a first aspect of the invention, the intravascular device comprises a main stent member having a tubular shape and a first end and a second end, the device having a first radiopaque marker (2401A) and a second radiopaque marker (2401B), the shape of each marker having at least two different profiles when viewed from different angles, the marker is positioned on the main stent member to be offset by less than 180 degrees relative to the other marker. In a second aspect, the intravascular device has a particular stent pattern in which at least one strut has a curvature in a curled profile for reducing the compression diameter, with the following features. 本发明涉及一种血管内装置，其具有由支柱和环圈组成的波状图案。在本发明的第一方面中，所述血管内装置包括具有管状形状以及第一端和第二端的主支架部件，所述装置具有第一不透射线标记物(2401A)和第二不透射线标志物(2401B)，每个标记物的形状在从不同角度观察时至少有两个不同的轮廓，所述标记物定位在所述主支架部件上以相对于另一个标记物偏移小于180度。在第二方面中，血管内装置具有特定的支架图案，其中至少一个支柱在卷曲轮廓中具有弯曲，用于减小压缩直径，其具有以下特征。
