Abstract
An apparatus is provided for replacing a native cardiac valve. The native cardiac valve has at least one leaflet and is surrounded by a native cardiac valve annulus having superior and inferior aspects. The apparatus comprises a barbell-shaped, expandable anchoring member including first, second, and main body portions extending between the end portions. The main body portion includes a channel defined by inner and outer surfaces. Each of the first and second end portions has a diameter greater than the diameter of the main body portion. The first and second end portions are sized to respectively contact the superior and inferior aspects of the native cardiac valve annulus when the expandable anchoring member is in an expanded configuration. The apparatus also includes an expandable support member operably disposed within the main body portion of the expandable anchoring member, and a prosthetic cardiac valve secured within the expandable support member.
