  • Patent number: 11957609
    Abstract: A delivery device for controllably delivering multiple implants (e.g., intravascular implants) is described herein. The delivery device may include a lockout mechanism to prevent against inadvertent implant deployment prior to initial use. The delivery device may also include a re-sheath mechanism to allow for re-sheathing of an inner core assembly prior to removal of the delivery device from an initial deployment site. The delivery device may also further include a mechanism configured to prevent against re-sheathing of a partially-deployed implant.

  • Publication number: 20220287859
    Abstract: A stent includes a high radial force segment and a highly flexible segment, where the diameters of the high radial force segment and the highly flexible segment are different. For example, the stent may be formed from a tube having varying diameters as it extends distally combined with increased strut density to achieve increased flexibility distally while reducing loss of radial stiffness. The stent may further be placed with an additional stent segment, where the additional stent segment has a radial force similar to the radial force of the highly flexible force segment.

  • Publication number: 20220257394
    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.
