STATIONARY INTRA-ANNULAR HALO DESIGNS FOR PARAVALVULAR LEAK (PVL) REDUCTION-PASSIVE CHANNEL FILLING CUFF DESIGNS
First Claim
1. A prosthetic heart valve configured to be expanded between native leaflets of a native aortic annulus of a patient, the prosthetic heart valve comprising:
- a collapsible and expandable stent extending in a flow direction between a proximal end and a distal end, the stent including an annulus section adjacent the proximal end and a plurality of struts shaped to form a plurality of cells connected to one another in a plurality of annular rows around the stent, the flow direction being defined from the proximal end toward the distal end;
a cuff attached to the annulus section of the stent;
a plurality of prosthetic valve leaflets each having a belly attached to the cuff between a first location and a second location downstream of the first location in the flow direction; and
a sealing structure attached to the annulus section of the stent, the sealing structure having a deployed condition with a diameter greater than a diameter of the proximal end of the stent when the stent is in an expanded use condition.

Abstract
A prosthetic heart valve may include a collapsible and expandable stent extending in a flow direction between a proximal end and a distal end, a cuff attached to an annulus section of the stent, a plurality of prosthetic valve leaflets each having a belly attached to the cuff between a first location and a second location downstream of the first location in a flow direction, and a sealing structure attached to the annulus section of the stent. The annulus section of the stent may be adjacent the proximal end. The stent may include a plurality of struts shaped to form a plurality of cells connected to one another in a plurality of annular rows around the stent. The sealing structure may have a deployed condition with a diameter greater than a diameter of the proximal end of the stent when the stent is in an expanded use condition.
