US 10,500,078 B2 · Implantable stent

Abstract

Implantable stents that include strips that are each comprised of main struts connected by first connectors, and adjacent strips are connected by second connectors. The strut connectors have a structure, including areas of expanded or reduced width or thickness, to account for venous applications. When used for venous applications, the stents convey benefit from configurations that improve flexibility (due to the greater elasticity of venous applications) while maintaining enough stiffness to resist pressure on the venous structure in selected areas (such as for the May-Thurner syndrome). The stents include particular structural characteristics that are particularly advantageous for (although not limited to) venous applications.

Dependent claims

A stent comprising:

at least one strip including a plurality of main struts and a plurality of first connector struts,
wherein the main struts are obliquely oriented to a longitudinal axis of the stent, and wherein the at least one strip extends circumferentially around the longitudinal axis of the stent,
wherein the first connector struts extend between and connect circumferentially adjacent pairs of the main struts and opposing ends of each main strut of the plurality of main struts define respective opposing edges of the at least one strip, and
wherein more than two first connector struts connect each circumferentially adjacent pair of the main struts;
and
a plurality of second connector struts, wherein ends of the second connector struts are connected to the main struts between ends of the main struts so as to reduce foreshortening of the stent during expansion.
