Abstract:
A prosthetic heart valve for replacing a native valve includes a collapsible and expandable stent having a proximal end and a distal end, and a valve assembly disposed within the stent, the valve assembly including a plurality of leaflets and a cuff annularly disposed about the stent. The cuff includes a surplus portion capable of forming a sealing structure having a diameter greater than a diameter of the proximal end of the stent when deployed.

Claim (Index 14):
A prosthetic heart valve for replacing a native valve, comprising:\n a collapsible and expandable stent having a proximal end, a distal end, and a plurality of struts forming rows of cells, the stent being movable between collapsed and deployed conditions; the stent in a deployed condition having a first diameter adjacent the proximal end, and a second diameter adjacent the distal end, the second diameter being greater than the first diameter; and a valve assembly disposed within the stent, the valve assembly including:\n a plurality of leaflets, each leaflet having an attached edge and a free edge; and \n a cuff annularly disposed on a surface of the stent to cover at least one row of cells, and having an attached end coupled to the stent at a location distal to the attached edges of the plurality of leaflets, \n the cuff in the collapsed condition of the stent having a free end extending past the proximal end of the stent and having a memory bias such that the free end is configured to roll over itself, and \n the cuff in the deployed condition of the stent having the free end rolled over itself at least one full revolution toward the distal end to form a sealing ring for sealing gaps between the prosthetic heart valve and a native valve annulus, the sealing ring having an outer sealing diameter that is greater than the first diameter, but smaller than the second diameter.
