Prosthetic aortic heart valves
First Claim
1. A prosthetic heart valve, comprising:
- an annular stent frame having an expanded condition and a collapsed condition, the stent frame including an annulus inflow portion, an aortic outflow portion, and a plurality of connecting struts, each of the connecting struts having a first end connected to the annulus inflow portion and a second end directly connected to the aortic outflow portion, the annulus inflow portion including a plurality of commissure structures that are spaced from one another in an annular direction around the annulus inflow portion, each of the commissure structures being cantilevered from at least a respective single point on a remaining structure of the annulus inflow portion not part of the commissure structures, each of the commissure structures having an associated pair of connecting struts disposed on opposite sides of the commissure structure in the annular direction, the annulus inflow portion being devoid of structure between each commissure structure and the associated pair of connecting struts; and
a plurality of valve leaflets supported by the annulus inflow portion.

Abstract
A prosthetic aortic valve includes an annular, annulus inflow portion that is designed to reside in or near the patient'"'"'s native aortic valve annulus, and an annular, aortic outflow portion that is designed to reside in the patient'"'"'s aorta downstream from at least a portion of the valsalva sinus. The annulus inflow portion and the aortic outflow portion are connected to one another by a plurality of connecting struts that are confined to regions near the commissures of the patient'"'"'s native aortic valve. The connecting struts are designed to bulge out into the valsalva sinus to help anchor the prosthetic valve in place. The valve is circumferentially collapsible to a relatively small diameter for less-invasive delivery into the patient. The valve circumferentially expands to a larger operational diameter when deployed at the implant site.

16. A prosthetic heart valve, comprising:
-
an annular stent frame having an expanded condition and a collapsed condition, the stent frame extending from a proximal end to a distal end and including an annulus inflow portion at the proximal end, an aortic outflow portion at the distal end, and a plurality of connecting struts connecting the annulus inflow portion to the aortic outflow portion, the annulus inflow portion including a plurality of commissure structures that are spaced from one another in an annular direction around the annulus inflow portion, each of the commissure structures being cantilevered from a respective pair of points on a remaining structure of the annulus inflow portion not part of the commissure structures, each of the commissure structures having a free end and an associated pair of connecting struts disposed on opposite sides of the commissure structure in the annular direction, the free ends being features of the annulus inflow portion that are closest to the aortic outflow portion, and the annulus inflow portion being devoid of structure between each commissure structure and the associated pair of connecting struts; and a plurality of valve leaflets supported by the annulus inflow portion. - View Dependent Claims (17, 18, 19)
