    Abstract: A replacement mitral 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 mitral 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 prosthetic mitral valve can include an outer frame, an inner frame, a valve structure, and a sealing member. The outer frame comprises a plurality of first struts arranged in a lattice pattern and defining a first lumen. The outer frame is self-expandable from a compressed state to an expanded state. The inner frame comprises a plurality of second struts arranged in a lattice pattern and defining a second lumen. The inner frame is disposed within the first lumen of the outer frame, is self-expandable from a compressed state to an expanded state. The valve structure comprises three leaflets made from pericardium and is mounted within the second lumen of the inner frame. The sealing member is coupled to and extends radially outwardly from an atrial end of the outer frame and is configured to engage native tissue of the heart on an atrial side of the native mitral valve.

    Abstract: A prosthetic valve assembly and method of implanting same is disclosed. The prosthetic valve assembly includes a prosthetic valve formed by support frame and valve leaflets, with one or more tethers each having a first end secured to the support frame and the second end attached to, or configured for attachment to, to papillary muscles or other ventricular tissue. The tether is configured and positioned so as to avoid contact or other interference with movement of the valve leaflets, while at the same time providing a tethering action between the support frame and the ventricular tissue. The valve leaflets may be flexible (e.g., so-called tissue or synthetic leaflets) or mechanical.

    IPC: A61F2/24

    Abstract: A prosthetic apparatus for implantation in a native mitral valve includes a main body for placement within the native mitral 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. An atrial sealing member is disposed along an atrial portion of the main body and ventricular anchors are coupled to a ventricular portion of the main body. The atrial sealing member impedes the flow of blood between the main body and the native annulus. The ventricular anchors are positioned outside the main body for capturing native mitral valve leaflets between the main body and the ventricular anchors.

    Abstract: This disclosure pertains generally to prosthetic devices and related methods for helping to seal native heart valves and prevent or reduce regurgitation therethrough, as well as devices and related methods for implanting such prosthetic devices. In some cases, a spacer having a single anchor can be implanted within a native heart valve. In some cases, a spacer having dual anchors can be implanted within a native heart valve. In some cases, devices can be used to extend the effective length of a native heart valve leaflet.

    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 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.
