a first stent wire and a second stent wire forming a cylindrical stent body, wherein the cylindrical stent body encloses an interior void space and defines an inner luminal side of the stent body;

a primary interlocking structure; and

a secondary interlocking structure,

wherein the primary interlocking structure includes (i) a first double-loop structure including a first loop formed of the first stent wire and defining a first loop opening and a second loop formed of the first stent wire and defining a second loop opening, and (ii) the second stent wire passing through the second loop opening,

wherein, in a view normal to a first plane containing the first loop and the second loop, the first double-loop structure further includes two intersection points formed by the first stent wire, where the first loop is between a first intersection point of the two intersection points and a second intersection point of the two intersection points, and the second loop is separated from the first loop by the second intersection point,

wherein, in an axial direction of the stent device and relative to the first intersection point, the second loop opening is more distal than the first loop opening,

wherein the first loop opening has a first length in the axial direction and the second loop opening has a second length in the axial direction, and the second length is greater than the first length,

wherein the secondary interlocking structure includes the first stent wire and the second stent wire passing over each other, and

wherein the first stent wire includes a first peak and a first valley and the first loop is located at the first peak or the first valley of the first stent wire.
