Stationary intra-annular halo designs for paravalvular leak (PVL) reduction—active channel filling cuff designs

A prosthetic heart valve configured to be expanded in an annulus of a native aortic valve of a patient, the prosthetic heart valve comprising:

• a collapsible and expandable stent extending in a flow direction from a proximal end to 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;
• a cuff attached to the annulus section of the stent and having an outer surface facing in radial directions orthogonal to the flow direction;
• a plurality of prosthetic valve leaflets attached to the cuff;
• and
• a plurality of sealing members in the annulus section of the stent, each sealing member having a first end, a second end, an open side facing toward the distal end of the stent and a closed side facing toward the proximal end of the stent so that blood flowing in a direction opposite the flow direction can enter at least one of the sealing members through the open side and cause an outer surface of the at least one sealing member to move away from the outer surface of the cuff, the sealing members including lower sealing members and upper sealing members, the upper sealing members being spaced a greater distance in the flow direction from the proximal end of the stent than the lower sealing members.
