Abstract
A stent includes a high radial/crush force segment and a highly flexible segment. In an aspect, a plurality of first ring struts connected such that each of the plurality of first rings comprises a sinusoidal pattern having a plurality of apices and troughs, each first ring connected to an adjacent first ring by at least one connector. The connector extends from a ring strut of the first ring from a position near an apex of the first ring to a ring strut of the adjacent first rings near an apex of the adjacent ring, and a second stent segment comprises a plurality of second rings connected to one another to form a series of second rings.

A stent, comprising:
- a first stent segment comprising a plurality of first rings connected to one another to form a series of said first rings, the first rings comprising:
- a plurality of first ring struts connected such that each of the plurality of first rings comprises a sinusoidal pattern having a plurality of apices and troughs, each first ring connected to an adjacent first ring by at least one connector, the connector extending from a ring strut of the first ring from a position offset from an apex of said first ring to a ring strut of the adjacent first rings offset from an apex of the adjacent ring, a second stent segment comprising a plurality of second rings connected to one another to form a series of said second rings wherein:
- the second stent segment is coupled to the first stent segment;
- said first stent segment has a first stiffness and a first chronic outward force and the second stent segment has a second stiffness and a second chronic outward force, wherein the first stiffness is different from the second stiffness and the first chronic outward force is different from the second chronic outward force.
