1. An implantable prosthetic valve comprising:
- an inflow end;
an outflow end;
a central longitudinal axis extending from the inflow end to the outflow end;
a radially collapsible and expandable annular frame comprising a plurality of commissure attachment posts and a plurality of sets of struts,wherein the plurality of commissure attachment posts are angularly spaced apart from each other around the central longitudinal axis;
wherein each set of struts extends circumferentially partially around the central longitudinal axis from a first respective commissure attachment post to a second respective commissure attachment post and comprises an upper perimeter and a lower perimeter, each of the upper and lower perimeters having an overall concave shape facing in a direction of the outflow end of the implantable prosthetic valve; and
a valve member supported within an interior of the radially collapsible and expandable annular frame.

Abstract
Implantable prosthetic valves are disclosed, methods of their use, and related fabrication techniques are disclosed. In some cases, the prosthetic valves disclosed herein can include frame, skirt, and valve components. The frame component can have an overall, generally scalloped shape comprising fewer struts and fabricated from less raw material than known frames. In some cases, the prosthetic valves disclosed herein can be crimped to a smaller diameter than can other known valves.

17. An implantable prosthetic valve comprising:
-
an inflow end; an outflow end; a central longitudinal axis extending in an axial direction from the inflow end to the outflow end; a radially collapsible and expandable annular frame comprising a plurality of commissure attachment posts and a plurality of sets of struts, wherein the plurality of commissure attachment posts are angularly spaced apart from each other around, and are aligned with, the central longitudinal axis;
wherein each set of struts extends circumferentially partially around the central longitudinal axis from a first respective commissure attachment post to a second respective commissure attachment post;wherein each set of struts comprises no more than two rows of struts along any axis aligned with the central longitudinal axis and further wherein each set of struts comprises at least one partial row of angled struts extending between the first and second respective commissure attachment posts; and a valve member supported within an interior of the radially collapsible and expandable annular frame. - View Dependent Claims (18, 19, 20)
