Abstract: A mechanism for adjusting the chordae connecting the leaflets of a mitral valve to the papillary muscles in order to restore normal functioning of the mitral valve. The devices or mechanisms can correct problems associated with both prolapsed leaflets and restricted leaflets to allow the leaflets to properly coapt, thereby preventing or minimizing regurgitation. In accordance with the invention, the mechanisms or devices used for adjusting the chordae can be delivered and implanted in a minimally invasive and/or percutaneous manner, such as via transapical methods, transfermoral methods, or trans-septal methods.
