摘要： A prosthetic heart valve for replacing a native valve includes a collapsible and expandable stent extending between a proximal end and a distal end. The stent includes an annulus section adjacent the proximal end and having a first diameter, a plurality of first struts forming cells, and a plurality of second struts connected to the annulus section and forming a plurality of deflecting cells expandable to define a second diameter larger than the first diameter. A valve assembly is disposed within the stent and a cuff is coupled to the stent and covers the plurality of deflecting cells.

摘要： A prosthetic heart valve includes a collapsible stent extending from an inflow end to an outflow end, and a cuff having an inflow end an outflow end. The stent includes first and second circumferential rows of cells defined by first and second pluralities of struts, respectively. The second circumferential row is positioned closer to the outflow end of the stent than the first circumferential row. At least one cell in the second circumferential row includes by a first strut opposed to a fourth strut and a second strut opposed to a third strut. A bridging feature in at least one cell in the second circumferential row includes first and second supplemental struts extending across an intermediate portion of the cell. The outflow end of the cuff is coupled to the stent along the bridging feature.
