Abstract
Disclosed is an open cell stent that has adjacent sets of circumferential struts connected by means of highly flexible, undulating, connecting struts. To decrease outward flaring of the circumferential struts when the pre-deployed stent is advance through highly curved vessels, each unconnected strut of the sets of circumferential struts has a decreased longitudinal length as compared to the longitudinal length of the circumferential struts that are connected by the flexible connecting struts. To decrease the propensity for outward flaring of the end set of circumferential struts, the longitudinal length of the end set of circumferential struts is shorter than the longitudinal length of the interior set of circumferential struts. Enhanced features of the circumferential sets of strut members of the stent are also disclosed. Specifically, variable strut width for the curved sections and the diagonal sections of the circumferential sets of strut members can be employed to enhance the stents radial rigidity and to provide enhanced radiopacity of the end sets of strut members compared to the radiopacity of the interior sets of strut members.
