Patent attributes
A stent of interconnected ring-shaped stent units formed by a continuous threadlike material that extends back and forth to form a zigzag pattern of segments extending between opposite side turned edge portions. The zigzag pattern forming the outer circumference of each ring-shaped stent unit with at least some of said turned edge portions at a same side of the segments having a shifted position along the stent axial direction relative to a position of others of said turned edge portions at that same side of the segments so that not all of the adjacent tuned edge portions at that same side of the segments are aligned along a common circle extending around the outer circumference of each ring-shaped stent unit. At least some of the turned edge portions are also formed to have a wider line width than the line width of the segments.
