Abstract
Prosthetic devices and frames for implantation at a cardiac valve annulus are provided that include an annular frame (having an inflow end and an outflow end) and a plurality of axial frame members that bridge two circumferentially extending rows of angled struts. The axial frame members can include a plurality of axially extending leaflet attachment members and a plurality of axial struts in a 1:1 ratio. Along each of the two rows, the frame can have at least three angled struts between adjacent axial frame members.
Claims24
An annular frame for a prosthetic heart valve,
- the annular frame comprising:
- an inflow end;
- an outflow end;
- a first row of angled struts defining the outflow end;
- a second row of angled struts being closer to the inflow end than the first row of angled struts;
- a third row of angled struts being closer to the inflow end than the second row of angled struts;
- and
- a plurality of axial frame members bridging the first and second rows of angled struts;
- wherein the plurality of axial frame members have respective first ends and second ends, the first ends being linked by the first row of angled struts and the second ends being linked by the second row of angled struts;
- wherein the plurality of axial frame members comprises a plurality of axially extending commissure supports configured to support respective commissures of leaflets of the prosthetic heart valve and one or more axial struts located between any two commissure supports;
- wherein at least three angled struts in the first row separate at least one commissure support and an immediately adjacent axial strut in a circumferential direction;
- wherein each axial strut bridges the first and second rows of angled struts, and is straight and extends parallel to the commissure supports along the entire length of the axial strut.
