First Claim
Patent Images
1. A prosthetic heart valve for replacing a native valve, comprising:
- a collapsible and expandable stent having a proximal end and a distal end;
a valve assembly disposed within the stent, the valve assembly including a plurality of leaflets; and
a cuff annularly disposed about the stent and having a surplus portion capable of forming a sealing structure at the proximal end of the stent, the sealing structure having a deployed condition with a diameter in the deployed condition greater than a diameter of the proximal end of the stent.

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.

13. A prosthetic heart valve for replacing a native valve, comprising:
-
a collapsible and expandable stent having a proximal end and a distal end; a valve assembly disposed within the stent, the valve assembly including a plurality of leaflets; and a cuff annularly disposed about the stent and having an attached end coupled to the stent and a free end extending past the proximal end of the strut and capable of forming a sealing structure for sealing gaps between the prosthetic heart valve and a native valve annulus.

17. A method of making a prosthetic heart valve for replacing a native valve, comprising:
-
providing a collapsible and expandable stent having a proximal end and a distal end; coupling a valve assembly to the stent, the valve assembly including a plurality of leaflets; coupling a cuff to the stent so that a surplus portion of the cuff extends beyond the proximal end of the strut; and converting the surplus portion of the cuff into a sealing structure at the proximal end of the stent, the sealing structure having a diameter greater than a diameter of the proximal end of the stent. - View Dependent Claims (18, 19)
