  • Prosthetic Heart Valve with Paravalvular Leak Mitigation Features
    Publication number: 20220354638
    Abstract: A prosthetic heart valve includes a collapsible stent and a valve assembly disposed within the stent. A first cuff is disposed adjacent the stent. A second cuff having a distal edge facing the outflow end of the stent is disposed about the stent radially outward of the first cuff and the stent. The stent may include a plurality of fingers each having a first end coupled to a corresponding cell of the stent and a free end adapted to extend radially outward of the corresponding cell. The distal edge of the second cuff may be coupled to the fingers at spaced locations around the circumference of the stent to position the distal edge radially outward from the corresponding cells at the spaced locations. Various stent struts may be tapered to reduce the stent circumference in the collapsed condition, and to improve the fatigue resistance and/or bendability of the stent.
    Type: Application
