Abstract

The present device has increased longitudinal flexibility in a stent by having some curved sections of each circumferential set of strut members being unconnected to the curved sections of the adjacent circumferential set of strut members with the other curved sections being connected by highly flexible, undulating longitudinal connecting links. The present device prevents flaring of the unconnected strut members by having a shorter longitudinal length for the unconnected strut members, and may have generally shorter longitudinal lengths for all the strut members in the circumferential sets of strut members at the stent ends to reduce the tendency for end flaring of the stent. Finally, the stent demonstrates that the flexible longitudinal connecting links of the curved sections of the sets of strut members are connected at a point that is close to the line where the diagonal sections join the curved sections, thus further reducing the propensity for end flaring.
