Abstract
A stent may comprise a plurality of interconnected struts including a central strut, a first strut on one side of the central strut and a second strut on the other side of the central strut, where a portion of one side of the central strut is nested within the first strut and a portion of the other side of the central strut is nested within the second strut. The nested portions of the central strut are more radiopaque than the remainder of the central strut. A cover may be disposed about the stent in the region of the central strut.

A medical device having a longitudinal axis, the device comprising a plurality of interconnected struts including:
- at least one special strut having a first side with a first region of first curvature relative to the longitudinal axis and a second side with a second region of second curvature relative to the longitudinal axis, the first region opposite the second region, the first region curving in a direction opposite to the second region relative to the longitudinal axis of the device, the special strut having a radiopaque marker between the first and second regions,
- one or more struts adjacent the first side of the special strut having a shape which is generally complementary to the shape of the first side, and
- one or more struts adjacent the second side of the special strut having a shape which is generally complementary to the shape of the second side.
A stent comprising a plurality of interconnected struts including:
- at least one strut having a region with an enlarged width with a greater radiopacity than the remainder of the strut, the strut having a shape,
- a first strut adjacent a first side of the strut having the region with the enlarged width, and
- a second strut adjacent a second side of the strut having the region with the enlarged width,
- the shapes of the first and second struts taken together complementing the shape of the strut having the region with the enlarged width.
A stent in an unexpanded state comprising a plurality of interconnected struts, the struts including a central strut, a first strut on one side of the central strut and a second strut on the other side of the central strut, a portion of one side of the central strut nested within the first strut and a portion of the other side of the central strut nested within the second strut, the nested portions of the central strut being more radiopaque than the remainder of the central strut.
