Abstract
A prosthetic heart valve includes a collapsible and expandable stent having a proximal end, a distal end, an annulus section adjacent the proximal end and an aortic section adjacent the distal end. The heart valve further includes a plurality of commissure features disposed on the stent, and a collapsible and expandable valve assembly, the valve assembly including a plurality of leaflets connected to the plurality of commissure features, each of the plurality of leaflets having a free edge and being configured to have a tension line aligned near the free edge to prevent backflow.
Claims22
A prosthetic heart valve, comprising:
- a collapsible and expandable stent having a proximal end, a distal end, an annulus section adjacent the proximal end and an aortic section adjacent the distal end;
- a plurality of commissure features disposed on the stent;
- and
- a collapsible and expandable valve assembly, the valve assembly including a plurality of leaflets connected to the plurality of commissure features, each of the plurality of leaflets having a free edge and a belly portion, and being configured to have a tension line aligned between the free edge and the belly portion to prevent backflow.
A prosthetic heart valve, comprising:
- a collapsible and expandable stent having a proximal end, a distal end, an annulus section adjacent the proximal end and an aortic section adjacent the distal end;
- a plurality of commissure features disposed on the stent;
- and
- a collapsible and expandable valve assembly, the valve assembly including a plurality of leaflets connected to the plurality of commissure features, each of the plurality of leaflets having a free edge, a belly portion and fibers configured and arranged to provide adequate coaptation.
A prosthetic heart valve, comprising:
- a collapsible and expandable stent having a proximal end, a distal end, an annulus section adjacent the proximal end and an aortic section adjacent the distal end;
- a plurality of commissure features disposed on the stent;
- and
- a collapsible and expandable valve assembly, the valve assembly including a plurality of leaflets connected to the plurality of commissure features, each of the plurality of leaflets having an attachment portion and a reinforcement coupled to the attachment portion.
A leaflet for a collapsible and expandable valve assembly, comprising:
- a belly portion having a first edge adapted to couple to at least one of a stent or a cuff, the belly portion having an area of reduced thickness;
- a free edge opposite the first edge adapted to coapt with free edges of other leaflets;
- and
- at least one tab adapted to couple the leaflet to a commissure feature of the stent.
