  • Publication number: 20200022810
    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: 10321995
    Abstract: The invention relates to a transcatheter heart valve replacement (A61F2/2412), and in particular an orthogonally delivered transcatheter prosthetic valve having a tubular frame with a flow control component mounted within the tubular frame and configured to permit blood flow in a first direction through an inflow end of the valve and block blood flow in a second direction, opposite the first direction, through an outflow end of the valve, wherein the valve is compressible to a compressed configuration for introduction into the body using a delivery catheter for implanting at a desired location in the body, said compressed configuration having a long-axis oriented at an intersecting angle of between 45-135 degrees to the first direction, and expandable to an expanded configuration having a long-axis oriented at an intersecting angle of between 45-135 degrees to the first direction, wherein the long-axis of the compressed configuration of the valve is substantially parallel to a length-wise cylindrical axis of

  • Publication number: 20190125533
    Abstract: Apparatus and methods are described herein for use in the transfemoral delivery and deployment of a prosthetic mitral valve. In some embodiments, a method includes inverting an outer frame of a prosthetic mitral valve when in a biased expanded configuration. After inverting the outer frame, the prosthetic mitral valve is inserted into a lumen of a delivery sheath such that the mitral valve is moved to a collapsed configuration. The delivery sheath is inserted into a femoral vein and moved through the femoral vein and a septum of a heart until a distal end of the delivery sheath is disposed in the left atrium of the heart. The prosthetic mitral valve is moved distally out of the delivery sheath such that the inverted outer frame reverts and the prosthetic mitral valve assumes its biased expanded configuration. The prosthetic mitral valve is then positioned within a mitral annulus of the heart.

  • Publication number: 20180271651
    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.

  • Publication number: 20170281343
    Abstract: Apparatus and methods are described herein for use in the transvascular delivery and deployment of a prosthetic mitral valve. In some embodiments, a method includes inverting an outer frame of a prosthetic mitral valve when the valve is in a biased expanded configuration. After inverting the outer frame, the prosthetic mitral valve is inserted into a lumen of a delivery sheath such that the mitral valve is moved to a collapsed configuration. The distal end portion of the delivery sheath is inserted into a left atrium of a heart. The prosthetic mitral valve is moved distally out of the delivery sheath such that the inverted outer frame reverts and the prosthetic mitral valve assumes its biased expanded configuration. In some embodiments, actuation wires are used to assist in the reversion of the outer frame. The prosthetic mitral valve is then positioned within a mitral annulus of the heart.

  • Publication number: 20170181854
    Abstract: A prosthetic heart valve can include an outer support assembly, an inner valve assembly, which define between them an annular space, and a pocket closure that bounds the annular space to form a pocket in which thrombus can be formed and retained. Alternatively, or additionally, the outer support assembly and the inner valve assembly can be coupled at the ventricle ends of the outer support assembly and the inner valve assembly, with the outer support assembly being relatively more compliant in hoop compression in a central, annulus portion than at the ventricle end, so that the prosthetic valve can seat securely in the annulus while imposing minimal loads on the inner valve assembly that could degrade the performance of the valve leaflets.
