Abstract: A prosthetic heart valve including a multi-part frame having an annular main body formed from a plurality of struts, an atrial anchor that extends radially outward from an inflow end portion of the main body, one or more ventricular anchors that are configured to be positioned behind a native valve leaflet, and a valve structure disposed in a lumen of the main body. Each of the ventricular anchors includes first and second end portions coupled to the outflow end portion of the main body and an intermediate portion forming a bend that forms a free end portion of the ventricular anchor that extends toward an inflow end portion of the main body. The multi-part frame is radially compressible for delivery within a sheath of a delivery catheter and is self-expandable for deployment within an annulus of a native valve.

Abstract: A prosthetic heart valve includes a multi-part frame having a first annular body and an anchor component that includes a second annular body circumscribing the first annular body. The first annular body includes a plurality of struts arranged in a lattice pattern and defining a lumen. The anchor component further includes one or more ventricular anchors extending from the second annular body toward an inflow end portion of the first annular body. A fabric layer is disposed on an inner surface of the first annular body and sutured to the struts. A valve structure including three leaflets is disposed within the lumen and inlet ends of the leaflets are sutured to the fabric layer. The multi-part frame is radially compressible for delivery within a sheath of a delivery catheter and is self-expandable for deployment within an annulus of a native valve.

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 replacement valve prosthesis includes a support structure and a valve body having three flexible leaflets. The support structure preferably includes an internal valve frame and an external sealing frame. The valve frame supports the flexible leaflets. The sealing frame is adapted to conform to the shape of the native heart valve annulus. The sealing frame may be coupled to an inlet end of the valve frame, an outlet end of the valve frame, or both. A plurality of anchors is coupled to the outlet end of the valve frame. The anchors extend radially outwardly for placement behind native leaflets. The prosthesis preferably includes a skirt disposed along an exterior of the external sealing frame. The prosthesis is collapsible for delivery into the heart via a delivery catheter. The prosthesis is configured to self-expand for deployment in the heart when released from the delivery catheter.

Abstract: A heart valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The prosthetic valve has a base stent that is deployed at a treatment site, and a valve component configured to quickly connect to the base stent. The base stent may take the form of a self- or balloon-expandable stent that expands outward against the native valve with or without leaflet excision. The valve component has a non-expandable prosthetic valve and a self- or balloon-expandable coupling stent for attachment to the base stent, thereby fixing the position of the valve component relative to the base stent. The prosthetic valve may be a commercially available to valve with a sewing ring and the coupling stent attaches to the sewing ring. The system is particularly suited for rapid deployment of heart valves in a conventional open-heart surgical environment. A catheter-based system and method for deployment is provided.

Abstract: A system, for use with a leaflet of a valve of a subject's heart, comprises a catheter, a cutting device, a helical needle, and a suture. The catheter is transluminally advanceable toward the heart. The cutting device is advanceable distally out of the catheter, and is adapted to cut through tissue of the leaflet to form cut tissue and cut edges at the cardiac valve. The helical needle defines a helical lumen, the helical needle configured to be advanced distally out of the catheter and to rotationally extend through, and secure together, two tissue segments of the leaflet. The suture extends through the helical lumen of the helical needle. The helical needle and the suture are configured to extend along the two tissue segments of the leaflet to suture the two tissue segments to each other. Other embodiments are also described.

Abstract: A system for replacing a native valve of the heart includes a delivery apparatus having a sheath and a prosthetic valve. The prosthetic valve includes a frame having an annular main body, a plurality of ventricular anchors attached to the main body, an atrial anchor attached to an atrial end portion of the main body, and a valve structure disposed within the main body of the frame. The prosthetic valve is disposed within a distal end portion of the sheath in a compressed, delivery state. When the prosthetic valve is deployed from the sheath, the main body of the frame radially expands to a radially expanded state, the ventricular anchors expand to a deployed state alongside the main body of the frame for capturing native leaflets of the native valve, and the atrial anchor expands to a deployed state extending radially outwardly from the main body.

Abstract: A prosthetic heart valve for implantation at a native heart valve includes a multi-part frame. The multi-part frame includes a cylindrical main body and a ventricular anchor component surrounding the main body. The main body includes a plurality of struts arranged in a lattice pattern. The ventricular anchor component is attached to the main body only at an outflow end of the main body and extends toward an inflow end of the main body. The prosthetic valve further includes a valve structure having three leaflets made from pericardium. The multi-part frame is radially compressible for delivery within a sheath of a delivery catheter and is self-expandable for deployment within an annulus of the native valve. The main body and the ventricular anchor component are formed separately and are attached by a locking mechanism for reducing strain between the main body and the ventricular anchor component.

Abstract: A prosthetic apparatus for implantation in a native heart valve includes a main body for placement within the native annulus. The main body is compressible to a radially compressed state for delivery into the heart and is self-expandable from the compressed state to a radially expanded state for implantation. A valve structure is mounted within a lumen of the main body and preferably forms three leaflets made of pericardium. Ventricular anchors are coupled to a ventricular end portion of the main body. The ventricular anchors are adapted to be straightened for delivery to the native heart valve and are biased to spring back to a pre-formed bent shape for capturing the native heart valve leaflets between the main body and the ventricular anchors. An atrial sealing member may be provided along an atrial portion of the main body for impeding the flow of blood between the main body and the native annulus.
