摘要:
A stent of the present disclosure has a variable radial force along the longitudinal length of the stent. In particular, the radial force of the center is greater than the radial force of the ends of the stent. Without being bound by theory, the radial force is affected by the strut angle ?, the wall thickness t, the number of strut pairs, and combinations thereof. In one aspect of the present disclosure, the stent has a variable strut angle ?, a variable wall thickness t, and a variable number of strut pairs. By adjusting the strut angle ?, the wall thickness t, and the number of strut pairs of the serpentine bands, the stent will have a variable radial force without the need for additional processing steps.
