Replacement heart valve prosthesis
First Claim
1. A replacement heart valve prosthesis for deployment at a native heart valve, the prosthesis comprising:
- an expandable frame configured to radially expand and contract for deployment within a native heart valve, the expandable frame comprising;
a frame body comprising a proximal region, a distal region, and an intermediate region extending between the proximal and distal regions, the frame body comprising a first row of struts and a second row of struts;
a supplemental frame comprising a first row of struts configured to be generally aligned along the first row of struts of the frame body, the first row of struts of the supplemental frame having a shape which generally matches the shape of the first row of struts of the frame body;
a proximal anchoring feature, the proximal anchoring feature sized to be positioned on a first side of an annulus of the native heart valve; and
a distal anchoring feature, the distal anchoring feature sized to be positioned on a second side of an annulus of the native heart valve; and
a valve body positioned within an interior of the expandable frame, the valve body comprising a plurality of leaflets configured to allow flow in a first direction and prevent flow in a second opposite direction;
wherein the plurality of leaflets each have an arcuate proximal edge and a free distal edge, the plurality of leaflets being joined at commissures, the plurality of leaflets configured to allow flow in a proximal-to-distal direction and prevent flow in a distal-to-proximal direction; and
wherein the valve body comprises one or more intermediate components connecting the leaflets to the expandable frame, wherein at least a portion of the arcuate proximal edge of each leaflet and/or the commissures are indirectly coupled to the expandable frame via the one or more intermediate components such that when the frame is in an expanded configuration, the one or more intermediate components position at least a portion of the arcuate proximal edge of each leaflet and/or the commissures radially inward from an inner surface of the expandable frame.

Abstract
A prosthesis can be configured to grasp intralumenal tissue when deployed within a body cavity and prevent axial flow of fluid around an exterior of the prosthesis. The prosthesis can include an expandable frame configured to radially expand and contract for deployment within the body cavity and a valve body. The expandable frame can include a frame body and a supplemental frame. The valve body can include a plurality of leaflets and one or more intermediate components. The one or more intermediate components can couple at least a portion of the leaflets to the expandable frame. The prosthesis can include an annular flap positioned around an exterior of the expandable frame.
