PROSTHETIC MITRAL VALVE
First Claim
Patent Images
1. A prosthetic mitral valve suitable to be deployed in a mammalian heart, comprising:
- a valve frame;
a frame aperture defined by the valve frame, said frame aperture sized to;
circumferentially enclose a prosthetic heart valve mechanism and fit within the mitral valve aperture between the heart left ventricle and atrium; and
at least one arm attached to the valve frame on the ventricular side of said frame aperture;
said at least one arm having a chord receiving surface sized and shaped to deploy among a region of chords of the native mitral valve and deflect the shape of chords contacted, pulling least one native mitral valve leaflet at least partially around said frame aperture.

Abstract
A prosthetic mitral valve with a frame comprises at least one arm shaped to deploy among a region of chordae tendineae of the native mitral valve to deflect these chords in order to pull the native valve leaflets around the frame to avoid paravalvular leaks. The frame may be made from two parts that are connected by sutures. The prosthetic valve may be deployed by a catherer comprising a deployment clamp attached to the valve frame where the deployment clamp is actuable to induce rotation of the frame.
