Abstract
A prosthetic heart valve includes a collapsible and expandable stent and a plurality of commissure features disposed on the stent. A collapsible and expandable valve assembly includes a plurality of leaflets connected to the plurality of commissure features, each commissure feature including a body having a proximal end and a distal end. A plurality of eyelets is arranged in rows and columns on the body for distributing load from the plurality of leaflets.
Claims24
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 commissure feature including a body having a proximal end a distal end, and a plurality of eyelets arranged in at least two rows and at least two columns for distributing load from the plurality of leaflets.
A prosthetic valve assembly for assembly to a collapsible and expandable stent, the stent including a plurality of commissure features, each commissure feature including a body having a longitudinal direction extending between a proximal end and a distal end, and a plurality of eyelets arranged in a plurality of columns each extending in the longitudinal direction, the body having a width in a direction orthogonal to the longitudinal direction, the valve assembly comprising:
- a plurality of leaflets, each leaflet having a top free edge for coapting with others of the leaflets and including at least one rectangular tab foldable upon itself along a fold line for attaching to a commissure feature at a leaflet-commissure feature junction, the at least one rectangular tab having a width which is at least as long as the width of the body.
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, each commissure feature including a body having a longitudinal direction extending between a proximal end and a distal end, and a plurality of eyelets arranged in at least two columns extending in the longitudinal direction and at least two rows extending in a direction orthogonal to the longitudinal direction, for distributing load from the plurality of leaflets;
- and
- a collapsible and expandable valve assembly, including a plurality of leaflets connected to the plurality of commissure features via a suture pattern.
