Abstract
A prosthetic heart valve is provided with a cuff having features which promote sealing with the native tissues even where the native tissues are irregular. The cuff may include a portion adapted to bear on the LVOT when the valve is implanted in a native aortic valve. The valve may include elements for biasing the cuff outwardly with respect to the stent body when the stent body is in an expanded condition. The cuff may have portions of different thickness distributed around the circumference of the valve in a pattern matching the shape of the opening defined by the native tissue. All or part of the cuff may be movable relative to the stent during implantation.

- 2. A pocket adapted for use in a prosthetic heart valve having a stent body, the pocket being sized and shaped for engagement within the native valve annulus to impede perivalvular leakage.
- 4. A cuff adapted for use in a prosthetic heart valve having a stent body, the cuff comprising at least one pocket sized, shaped and positioned on the stent body for engagement within the native valve annulus to impede perivalvular leakage.

8. A cuff adapted for use in a prosthetic heart valve having a stent body, the cuff comprising at least one pocket and being sized, shaped and positioned on the stent body for engagement within the native valve annulus to impede perivalvular leakage.
- 10. A pocket adapted for use in a prosthetic heart valve having a stent body, the pocket having an outer surface and being sized and shaped to fill with blood upon blood flow around the stent body to bias the outer surface outwardly into engagement within the valve annulus.
- 12. A cuff adapted for use in a prosthetic heart valve having a stent body, the cuff comprising at least one pocket having an outer surface, the pocket being sized and shaped to fill with blood upon blood flow around the stent body to bias the outer surface outwardly into engagement within the valve annulus.
