Abstract
A stented valve prosthesis for implantation within a native mitral valve having a generally tubular expandable stent structure having a first end, a second end, a central body portion having one or more openings, and a longitudinal axis. A wing portion extends outwardly from the stent structure and away from the longitudinal axis of the stent structure in an expanded deployed configuration. A radius of the wing portion is greater than a radius of the central body portion in the expanded deployed configuration, and the wing portion fits within one of the openings in the central body portion of the stent structure in a crimped delivery configuration. A valve structure having a plurality of leaflets is attached to an interior of the stent structure.

36. A stented valve prosthesis for implantation within a native mitral valve, comprising:
-
a generally tubular stent structure comprising a first end, a second end, a central body portion, and a longitudinal axis; a wing portion extending outwardly from the first end of the stent structure toward the second end of the stent structure and away from the longitudinal axis of the stent structure over an area of reduced wire density of the stent structure, wherein a radius of the wing portion is greater than a radius of the central body portion; and a valve structure comprising a plurality of leaflets attached to an interior of the stent structure. - View Dependent Claims (37, 38, 39)

40. A method of implanting a stented valve prosthesis within a native mitral valve, comprising:
-
inserting a delivery system with the stented valve prosthesis into a body lumen, the stented valve prosthesis comprising; a generally tubular expandable stent structure comprising a first end, a second end, a central body portion having one or more openings, and a longitudinal axis; a wing portion extending outwardly from the stent structure and away from the longitudinal axis of the stent structure in an expanded deployed configuration, wherein a radius of the wing portion is greater than a radius of the central body portion in the expanded deployed configuration, and wherein the wing portion its within one of the openings in the central body portion of the stent structure in a crimped delivery configuration; and a valve structure comprising a plurality of leaflets attached to an interior of the stent structure; and deploying the stented valve prosthesis at an implantation location within the native mitral valve. - View Dependent Claims (41, 42, 43)
