Publication number: 20200069448Abstract: 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: November 1, 2019Publication date: March 5, 2020Inventors: Michael A. Longo, William James Harrison

Publication number: 20190247209Abstract: 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.Type: ApplicationFiled: February 15, 2018Publication date: August 15, 2019Inventors: Michael A. Longo, Bruce J. Shook, William James Harrison

Publication number: 20190060052Abstract: Self-expending stents that include circumferential rings of alternating interconnected struts connected by flexible connectors. The struts of the rings and flexible 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—often expressed as ratios between different measurements—that are particularly advantageous for (although not limited to) venous applications.Type: ApplicationFiled: August 23, 2017Publication date: February 28, 2019Inventors: William James Harrison, Michael A.

Publication number: 20160374839Abstract: A delivery device can provide sequential delivery of a plurality of intraluminal devices or tacks held in a compressed state on the delivery device. Delivery platforms on the delivery device can hold a tack in a compressed position and have a unique shape, such as a non-constant outer diameter, an hourglass shape, a tapered proximal half, ridges, dimples, etc. This unique shape can be positioned between annular pusher bands that may also be radiopaque markers. In some embodiments, the unique shape is provided by a sleeve of flexible material with the unique shape surrounding a harder inner shaft. Further, the annular pusher bands can be made of wire or sections of material to increase flexibility while remaining radiopacity. A tack deployment method can include alignment of radiopaque markers on the outer sheath and the tack to be deployed prior to deployment.Type: ApplicationFiled: June 27, 2016Publication date: December 29, 2016Inventors: Michael Longo, Douglas Evans, William James Harrison
