  • Radiopaque elements for surgical heart valves
    Patent number: 11730588
    Abstract: Aspects of the disclosure include a prosthetic heart valve including a stent structure forming a plurality of commissure posts, a valve structure supported by the stent structure, a base supporting the stent structure and at least one radiopaque element positioned around the base. The radiopaque element can include a band extending around the base. In some embodiments the band is coiled. The band can optionally include a badge with an indicator specifying properties of the valve and viewable under fluoroscopy. In some embodiments, the radiopaque element is a badge that can have an indicator.
