Replacement heart valve
First Claim
Patent Images
1. A method of delivering a replacement valve to a native mitral valve of a heart 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 the replacement valve to the native mitral valve annulus while the replacement valve is in a radially compacted state, the replacement valve comprising;
an expandable frame having a proximal end ending at a proximalmost end and a distal end ending at a distalmost end;
a valve body positioned within a lumen of the expandable frame; and
one or more distal anchors extending from the distal end of the expandable frame and sized to contact tissue on a ventricular side of the native mitral valve when the replacement valve is deployed within the native mitral valve; and
deploying the replacement valve within the native mitral valve annulus such that;
the replacement valve is in an expanded configuration with a cross-sectional diameter of the distalmost end of the expandable frame being greater than a cross-sectional diameter of the proximalmost end of the expandable frame, the replacement valve only decreasing or remaining constant in cross-sectional diameter from the distalmost end to the proximalmost end;
the one or more distal anchors are positioned radially outwardly from the frame;
tips of the one or more distal anchors extend substantially parallel to a longitudinal axis of the expandable frame; and
at least one of the distal anchors extends between chordae tendineae of the native mitral valve.

Abstract
A replacement heart valve can have an expandable frame configured to engage a native valve annulus. A valve body can be mounted onto the expandable frame to provide functionality similar to a natural valve. The valve body has an upstream end and a downstream end, and a diameter at the downstream end is greater than a diameter at the upstream end.
