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.
Claims19
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 a plurality of rows of angled struts arranged in a zig-zag pattern in each row of angled struts, wherein each set of struts comprises at least one complete row of angled struts extending from the first respective commissure attachment post to the second respective commissure attachment post and at least two partial rows 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.
