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.

Abstract: A stented valve having at least one leaflet made of pericardium or other material having a relatively thin profile at the annulus. The leaflets are attached via chords to a stent frame, where the chords are positioned to mimic the native valve anatomy and functionality. In particular, the valves of one exemplary embodiment of the invention are sized to replace a mitral valve and therefore the chords are arranged to prevent prolapse of the leaflets into the atrium. The stented valve has a relatively short height at its annulus due to the positioning of the chords. In addition, the stented valve is capable of being crimped to a small enough size that it can be delivered to the implantation site via transcatheter delivery systems and methods.
Abstract translation: 一种支架瓣膜，其具有至少一个由心包或其他材料制成的传单，所述小叶在环形空间处具有较薄的轮廓。 传单通过和弦连接到支架框架上，其中和弦被定位以模拟天然瓣膜解剖结构和功能。 特别地，本发明的一个示例性实施例的阀的尺寸被设计成代替二尖瓣，并且因此设置弦杆以防止小叶向中庭脱垂。 由于和弦的定位，支架瓣膜在其环形处具有相对短的高度。 此外，支架瓣膜能够被卷曲到足够小的尺寸，使得其可以经由经导管递送系统和方法递送到植入部位。
