Abstract: Disclosed are cardiac shunts and method of delivery, and in particular, to a shunt to reduce elevated left atrial pressure (LAP). The methods include forming a puncture hole between the left atrium and the coronary sinus, widening the puncture hole, and placing an expandable shunt within the widened puncture hole. A first catheter having a side-extending needle may be used to form a puncture into the left atrium. A second catheter extends along a guidewire and an expandable shunt with distal and proximal flanges is expelled therefrom into the puncture. The shunt defines a blood flow passage therethrough that permits shunting of blood from the left atrium to the coronary sinus when the LAP is elevated. The shunt is desirable formed of a super-elastic material and manipulated with control rods. The shunt defines a tilted flow tube that facilitates collapse into the catheter.

Abstract: Embodiments of an apparatus, and a method for crimping expandable stents or prosthetic valves having a radially expandable and compressible annular body and one or more protruding anchors extending from the body using the apparatus, where the apparatus comprise a housing, a plurality of circumferentially arranged nesting jaws, and an actuator configured to move the jaws radially inwardly to reduce the size of the crimping aperture, thereby radially compressing the annular body of the prosthetic valve or stent. In particular embodiments, a selected set of the jaws, each having a front side and a recessed portion in its front side adjacent to its inner end. The recessed portions of the selected jaws collectively are sized and shaped to receive the one or more anchors of the prosthetic valve when the annular body is positioned within the crimping aperture.

Abstract: Embodiments of prosthetic valves for implantation within a native mitral valve are provided. One embodiment of a prosthetic valve includes a radially compressible main body and a one-way valve member. In some cases, the prosthetic valves also include ventricular anchors and/or an atrial portion coupled to and disposed outside of the main body. Methods, devices, and systems for delivering such prosthetic valves to the native mitral valve and implanting them therein are also provided.

Abstract: An implantable prosthetic valve includes a radially collapsible and radially expandable annular frame. The frame includes an annular main body sized to be implanted within a native mitral valve annulus. The frame also includes an atrial sealing member coupled to and extending radially away from the main body. The atrial sealing member is sized to extend over tissue of the native mitral annulus within a left atrium to reduce paravalvular leakage. The atrial sealing member includes an inner zig-zag portion and an outer zig-zag portion. The inner zig-zag portion and the outer zig-zag portion are connected to the main body portion only via a fabric to enhance flexibility of the atrial sealing member relative to the main body. The prosthetic valve also includes a valve member disposed within an interior of the frame.

Abstract: A method of implanting a prosthetic apparatus preferably includes delivering the prosthetic apparatus to a native mitral valve and exposing ventricular anchors and a spacer body of the prosthetic apparatus from a distal end portion of a delivery apparatus. The ventricular anchors are controllably and forcibly expanded outwardly from the spacer body to an expanded configuration. The prosthetic apparatus is positioned relative to the native mitral valve such that native mitral valve leaflets are located between the ventricular anchors and the spacer body. The ventricular anchors are then contracted radially inwardly toward the spacer body to a compressed configuration. In the compressed configuration, the native mitral valve leaflets are secured between the ventricular anchors and the spacer body. After implantation, the spacer body is held between the native mitral valve leaflets, thereby blocking regurgitation and improving the function of the native mitral valve.

Abstract: A prosthetic heart valve includes a collapsible and expandable frame having a main body, an atrial portion, and at least one ventricular anchor. The atrial portion extends radially outwardly relative to the main body and the ventricular anchor extends from a ventricular end of the main body. The main body and the atrial portion are preferably separate metal components that are coupled together via sutures or a fabric member. The prosthetic heart valve also includes a valve structure that is supported in the main body of the frame. The valve structure has a plurality of leaflets for regulating the flow of blood in one direction.
