Publication number: 20220257394Abstract: 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.Type: ApplicationFiled: April 29, 2022Publication date: August 18, 2022Inventors: Michael A.
