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.

2. 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 discrete 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 discrete beads being configured to fill gaps between the stent and body tissue. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16)

21. A method of sealing a prosthetic heart valve in a patient, comprising:
-
positioning the prosthetic heart valve within body tissue, the prosthetic heart valve comprising (i) a collapsible and expandable stent (ii) a valve assembly including a and (iii) a first conformable band including a plurality of discrete beads extending around a circumference of the stent; and expanding the stent until the plurality of discrete beads are in sealing contact with the body tissue.
