Abstract
In some embodiments, a method for delivery and deployment of a prosthetic mitral valve into a heart includes inserting an introducer sheath having a prosthetic mitral valve disposed therein in a collapsed configuration into the left atrium of a patient's heart, through a gap between the native mitral valve leaflets, the left ventricle and apex of the heart. An epicardial pad device coupled to the prosthetic valve via a tether is moved distally out of the sheath. The introducer sheath is withdrawn into the left atrium of the heart. An inner delivery sheath is extended distally from within the introducer sheath and disposed within the left atrium. The prosthetic mitral valve is moved distally out of the inner delivery sheath and assumes a biased expanded configuration. The valve is positioned within the mitral annulus of the heart, and secured in place via the tether and epicardial pad device.
