Abstract
A prosthetic heart valve includes a stent having a collapsed condition and an expanded condition. The stent includes a plurality of cells, each cell being formed by a plurality of struts, and a plurality of commissure features. The heart valve further includes a valve assembly secured to the stent and including a cuff and a plurality of leaflets, each leaflet being attached to adjacent commissure features and to the stent struts and/or the cuff.
Claims23
A prosthetic heart valve, comprising:
- a stent having a collapsed condition and an expanded condition, the stent having a proximal end, a distal end and a plurality of cells, each cell being formed by a plurality of struts;
- and
- a valve assembly secured to the stent and including a cuff and a plurality of leaflets, each leaflet having a folded portion and being coupled to the cuff at the folded portion.
A prosthetic heart valve, comprising:
- a stent having a collapsed condition and an expanded condition, the stent having a proximal end, a distal end and a plurality of cells, each cell being formed by a plurality of struts;
- a plurality of commissure features disposed on the stent;
- and
- a valve assembly secured to the stent and including a cuff and a plurality of leaflets cuff between the plurality of commissure features and the proximal end of the stent, each of the leaflets being coupled only to the cuff.
A prosthetic heart valve, comprising:
- a stent having a collapsed condition and an expanded condition, the stent including a plurality of cells, each cell being formed by a plurality of struts;
- and
- a valve assembly secured to the stent and including a cuff and a plurality of leaflets, each leaflet including a first edge adjacent to the cuff and a second edge spaced apart from the cuff, each leaflet being attached to the stent such that at least a portion of the first edge of each leaflet is disposed along at least one strut of the stent.
A prosthetic heart valve, comprising:
- a stent having a collapsed condition and an expanded condition, the stent including a plurality of cells, each cell being formed by a plurality of struts;
- and
- a valve assembly secured to the stent and including a cuff and a plurality of leaflets, each leaflet including a first edge adjacent to the cuff and a second edge spaced apart from the cuff, each leaflet being attached to the cuff such that at least a portion of the first edge of each leaflet is disposed at a substantially uniform distance from at least one strut of the stent.
