First Claim
Patent Images
1. A method of delivering a replacement valve to a native mitral valve and securing the replacement valve relative to the native mitral valve annulus, the native mitral valve annulus supporting native leaflets, the method comprising:
- delivering a replacement valve mounted on 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 and a first plurality of anchors extending from the frame;
positioning the replacement valve so that tips of the first plurality of anchors are on a ventricular side of the native leaflets beyond a location where chordae tendineae connect to free ends of the native leaflets;
releasing at least a portion of the replacement valve from the delivery device to thereby expand the first plurality of anchors radially outwardly; and
engaging tips of the first plurality of anchors with tissue on a ventricular side of the native valve annulus with the first plurality of anchors extending between at least some of the chordae tendineae.
