  • Patent number: 11318012
    Abstract: 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 The introducer sheath is withdrawn into the left atrium of the heart.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.

  • Patent number: 11311379
    Abstract: A prosthetic heart valve includes a self-expanding wire frame body, a valve disposed in the body, a leaflet clip coupled to the body, and a control element operably coupled to the leaflet clip. The body has a proximal end and a distal end. The leaflet clip is configured to be transitioned between a first configuration in which the prosthetic valve can be inserted into a heart, and a second configuration in which the leaflet clip is disposed to capture a native valve leaflet between the leaflet clip and the wire frame body when the body is disposed in a native annulus of an atrioventricular valve of a heart. The control element extends from the leaflet clip through a ventricle of the heart and out a wall of the ventricle to allow a user to transition the leaflet clip from its first configuration to its second configuration.

  • Patent number: 11096782
    Abstract: Prosthetic heart valves are described herein that can provide clearance to the left ventricle outflow tract (LVOT), reduce the possibility of undesirable outflow gradients, and/or limit or prevent LVOT obstructions when implanted in the heart. In some embodiments, a prosthetic heart valve can include an outer frame having a cuff portion that is disposed at an angle (e.g., 80 degrees) relative to the vertical axis of a body portion of the outer frame, so that the prosthetic valve can seat securely in the annulus while not obstructing the ventricular outflow tract of the heart. In some embodiments, a prosthetic heart valve can alternatively, or additionally, include subvalvular components having a short profile, such that the prosthetic valve can seat securely in the annulus while not obstructing the ventricular outflow tract of the heart.
