The invention is device and method for reducing regurgitation through a
mitral valve. The device and method is directed to an anchor portion for
engagement with the heart wall and an expandable valve portion configured
for deployment between the mitral valve leaflets. The valve portion is
expandable for preventing regurgitation through the mitral valve while
allowing blood to circulate through the heart. The expandable valve
portion may include apertures for reducing the stagnation of blood. In a
preferred configuration, the device is configured to be delivered in
two-stages wherein an anchor portion is first delivered and the valve
structure is then coupled to the anchor portion. In yet another
embodiment, the present invention provides a method of forming an anchor
portion wherein a disposable jig is used to mold the anchor portion into
a three-dimensional shape for conforming to a heart chamber.
