Abstract
A prosthetic heart valve includes a collapsible and expandable stent having a proximal end, a distal end, an annulus section adjacent the proximal end and an aortic section adjacent the distal end. The stent is formed of a plurality of struts. A cuff is coupled to the stent. The cuff has one or more features configured to reduce abrasion and/or perivalvular leakage.
