1. A prosthetic device for implantation at a cardiac valve annulus, the prosthetic device comprising:
- an annular frame having an inflow end, an outflow end, at least four circumferentially extending rows of angled struts, and a plurality of axial frame members bridging two of the circumferentially extending rows of angled struts that are closest to the outflow end, wherein each axial frame member has a first end closer to the inflow end and a second end closer to the outflow end, and the plurality of axial frame members comprises a plurality of axially extending leaflet attachment members and a plurality of axial struts in a 1;
1 ratio, and further wherein there is exactly one row of angled struts linking the second ends of the axial frame members and no more than one row of angled struts between the second ends of the plurality of axial frame members and the outflow end, and there are at least three rows of angled struts between the first ends of the plurality of axial frame members and the inflow end.

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.

18. A prosthetic device for implantation at a cardiac valve annulus, the prosthetic device comprising:
-
an annular frame having an inflow end, an outflow end, at least four rows of circumferentially extending angled struts, and exactly six axial frame members bridging two rows of the four rows of circumferentially extending angled struts, wherein the plurality of axial frame members comprises exactly three axially extending leaflet attachment members and exactly three axial struts; wherein each axial frame member has a first end closer to the inflow end and a second end closer to the outflow end, and there is exactly one row of angled struts linking the second ends of the six axial frame members and no more than one row of angled struts between the second ends of the six axial frame members and the outflow end, and there are at least three rows of angled struts between the first ends of the six axial frame members and the inflow end; wherein each of the two rows bridged by the six axial frame members comprises exactly three angled struts between each pair of a leaflet attachment member and an adjacent axial strut and exactly six angled struts between adjacent leaflet attachment members; and a tri-leaflet valve member positioned within the frame having commissures that are secured to the frame at the leaflet attachment members; wherein the commissures are secured to the leaflet attachment members adjacent to the outflow end of the frame. - View Dependent Claims (19, 20)
