Claim Text:
1. A method of delivering a replacement valve to a native mitral valve and securing the replacement valve relative to a native mitral valve annulus, the native mitral valve positioned between a left atrium and a left ventricle, the method comprising: delivering a replacement valve mounted on or within a delivery device to the native mitral valve annulus while the replacement valve is in a radially compacted state, the replacement valve comprising a radially expandable frame extending along a longitudinal axis between a first end and a second end and a plurality of first anchors extending from the frame; positioning the replacement valve so that the plurality of first anchors are on a ventricular side of the native mitral valve annulus; releasing a portion of the replacement valve from the delivery device so that the portion of the replacement valve at least partially radially expands and the plurality of first anchors are positioned radially from the delivery device on the ventricular side of the native mitral valve annulus while extending outwardly from the frame in a direction generally pointing towards the left atrium; after the plurality of first anchors are positioned radially from the delivery device on the ventricular side of the native mitral valve annulus, moving the replacement valve axially toward the native mitral valve so that the plurality of first anchors engage tissue on a ventricular side of the native mitral valve annulus; and with the plurality of first anchors engaging tissue on the ventricular side of the native mitral valve annulus, further releasing the replacement valve from the delivery device and expanding the frame to a radially expanded state.
