1. A heart valve assembly, comprising:
- a frame that assumes a compressed configuration and an expanded configuration, the frame comprising an inflow section, an outflow section, and a connecting section that is located between the inflow section and the outflow section, the inflow section having a plurality of legs that extend radially outwardly in the expanded configuration, and wherein the connecting section has a greater flexibility than the inner section; and
a leaflet and skirt assembly having a plurality of leaflets coupled to the connecting section, a valve skirt extending from the leaflets towards the inflow section of the frame, and a cuff section, wherein the legs and the cuff section define a cuff in the expanded configuration for engagement with a native annulus.

Abstract
A heart valve assembly has a frame comprising an inflow section, an outflow section, and a connecting section that is located between the inflow section and the outflow section. The inflow section has a plurality of legs that extend radially outwardly, and the connecting section has a greater flexibility than the inner section. The assembly also includes a plurality of leaflets coupled to the connecting section, a valve skirt extending from the leaflets towards the inflow section of the frame, and a cuff section, with the legs and the cuff section together defining a cuff for engagement with a native annulus.

9. A heart valve assembly, comprising:
-
a frame that assumes a compressed configuration and an expanded configuration, the frame comprising an inflow section, an outflow section, and a connecting section that is located between the inflow section and the outflow section, the inflow section having a plurality of legs; and a leaflet and skirt assembly having a plurality of leaflets coupled to the connecting section, a valve skirt extending from the leaflets towards the inflow section of the frame, and a cuff section, wherein the legs and the cuff section define a cuff in the expanded configuration for engagement with a native annulus; wherein the plurality of legs define an annular flange of legs that has the same diameter as the remainder of the frame when the frame and the legs are in the compressed configuration, and wherein the plurality of legs extend radially outwardly in the expanded configuration so that the flange of legs has a greater diameter than the remainder of the frame in the expanded configuration. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A method for deploying an aortic valve assembly at a native aortic annulus, comprising the steps of:
-
providing a heart valve assembly comprising a frame having an inflow section, an outflow section, and a connecting section that is located between the inflow section and the outflow section, the inflow section having a plurality of legs, and a leaflet and skirt assembly having a plurality of leaflets coupled to the connecting section, a valve skirt extending from the leaflets towards the inflow section of the frame, and a cuff section; crimping the frame and the leaflets and skirt assembly onto a delivery device with the plurality of legs defining an annular flange of legs that has the same diameter as the remainder of the frame; delivering the heart valve assembly to a location adjacent a native aortic annulus; releasing the inflow section from the delivery device so that the plurality of legs expands to assume its shape memory deployed configuration and together with the cuff section defines a cuff that engages the native aortic annulus, with the flange of expanded legs having a diameter that is larger than the diameter of the remainder of the frame; and releasing the connecting section and the outflow section from the delivery device. - View Dependent Claims (18)
