1. A prosthetic heart valve, comprising:
- a collapsible and expandable stent having a proximal end and a distal end;
a cuff coupled to the stent;
a valve assembly including a plurality of leaflets coupled to at least one of the stent or the cuff; and
a conformable band having an inner surface disposed near the perimeter of the stent adjacent the plurality of leaflets and an outer surface adapted for contacting body tissue, the conformable band being configured to seal the valve assembly against leakage by filling gaps between the prosthetic heart valve and the body tissue.

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.

16. 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 plurality of leaflets coupled to the stent and (iii) a conformable band having an inner surface disposed about the plurality of leaflets and an outer surface adapted for contacting body tissue; expanding the stent until the conformable band is in sealing contact with the body tissue.
