Abstract
A prosthetic heart valve includes a collapsible and expandable stent having a proximal end and a distal end, and a collapsible and expandable valve assembly, the valve assembly including a plurality of leaflets connected to at least one of the stent and a cuff. The heart valve further includes a conformable band disposed about the perimeter of the stent near the proximal end for filling gaps between the collapsible prosthetic heart valve and a native valve annulus.
Claims20
A prosthetic heart valve, comprising:
- a collapsible and expandable stent having a proximal end, and a distal end, the stent in an expanded condition having a minimum diameter and a maximum diameter, the maximum diameter being greater than the minimum diameter;
- a valve assembly including a plurality of leaflets coupled to the stent, and a cuff coupled to the stent, the cuff having a first edge and a second edge;
- and
- a first conformable band including a plurality of distinct beads defining a plurality of alternating peaks and valleys, each of the plurality of distinct beads being connected to adjacent beads, the first conformable band being disposed between the first edge and the second edge of the cuff around a portion of a circumference of the stent, and having an outer diameter that is greater than the minimum diameter and less than the maximum diameter, each of the plurality of distinct beads being configured to fill gaps between the stent and body tissue.
