  • Publication number: 20210298929
    Abstract: Methods and devices relate to the use and construction of a vascular stent. A stent assembly includes mesh structure that is at least partially attached to a support or stent structure. The stent structure is formed of one or more struts that collectively form a tubular body sized to fit within a blood vessel. The mesh structure is formed of one or more filaments or sutures that are interwoven or knit to form a structure that is coupled to the stent structure. The mesh structure can at least partially cover or at least be partially covered by the stent structure.
