Abstract

Claims (15)

1. A prosthetic heart valve for replacing a native valve, comprising:

a collapsible and expandable stent having a proximal end, a first section adjacent the proximal end, a distal end, a second section adjacent the distal end, a plurality of struts forming rows of cells, 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;

a valve assembly disposed within the stent, the valve assembly including a plurality of leaflets, each leaflet having an attached edge and a free edge, and a valve cuff annularly disposed on a surface of the stent to cover at least one of the rows of cells; and

a surplus cuff portion extending proximally past a proximal-most row of cells and being formed of a thickened material that is configured to circumferentially buckle at predetermined locations to form an undulating sealing ring including a series of alternating peaks that extend toward the distal end and valleys that extend toward the proximal end.

2. The prosthetic heart valve as claimed in claim 1 , wherein the surplus cuff portion is unitary with the valve cuff.

3. The prosthetic heart valve as claimed in claim 1 , wherein the surplus cuff portion extends from the proximal-most row of cells by at least 5 mm.

4. The prosthetic heart valve as claimed in claim 1 , wherein the surplus cuff portion extends from the proximal-most row of cells by between 5 mm and 20 mm.

5. The prosthetic heart valve as claimed in claim 1 , wherein the surplus cuff portion is configured to circumferentially buckle in an accordion-like fashion.

6. The prosthetic heart valve as claimed in claim 1 , further comprising terminal sutures configured to attach portion of surplus cuff to selected struts of the stent.

7. The prosthetic heart valve as claimed in claim 6 , wherein the terminal sutures are also used to attach the valve cuff to the stent.

8. The prosthetic heart valve as claimed in claim 1 , wherein the surplus cuff portion is configured to radially expand to a diameter greater than the first diameter.

9. The prosthetic heart valve as claimed in claim 1 , wherein the surplus cuff portion comprises porcine pericardial tissue.

10. The prosthetic heart valve as claimed in claim 1 , wherein the surplus cuff portion comprises UHMWPE.

11. The prosthetic heart valve as claimed in claim 1 , wherein the surplus cuff portion comprises PET fabric.

12. The prosthetic heart valve as claimed in claim 1 , wherein the surplus cuff portion is formed of a same material as the valve cuff.
