Abstract
The invention is a 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 preferably 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.
