摘要： A method of implanting a replacement mitral valve can include expanding a replacement mitral valve to a first expanded configuration. The replacement mitral valve can include a force-expanding mitral valve lattice and a self-expanding valve trampoline lattice. The mitral valve lattice has an inflow end portion and an outflow end portion, and the valve trampoline lattice is attached to the outflow end portion of the mitral valve lattice. The method can also include rotating a plurality of jack screws connected to the mitral valve lattice. The jack screws can be configured to expand the mitral valve lattice from the first expanded configuration to a second expanded configuration.

摘要： Embodiments of the present disclosure provide a prosthetic heart valve. The prosthetic heart valve includes an outer frame, an inner frame positioned at least partially within the outer frame, and an occluder member positioned at least partially within the inner frame. The prosthetic heart valve also includes an atrial flange extending from an atrial end of the outer frame, and a ventricular flange extending from a ventricular end of the outer frame, wherein at least a portion of the atrial flange extends radially outward beyond the ventricular flange.

摘要： A prosthetic valve includes a tubular frame, a multi-leaflet valve, movable rods, and a flange. The frame includes a lattice, an inflow end portion, and an outflow end portion. The frame is movable between radially collapsed and expanded states. The lattice deflects as the frame moves between the radially collapsed and expanded states. The valve is disposed within and coupled to the frame and is configured to allow one-way blood flow therethrough. The rods are coupled to the lattice of the frame and are configured to facilitate movement of the frame between the radially collapsed and expanded states. The flange is coupled to and extends radially outwardly from the frame and includes deflectable petals. The petals include a first petal having a first length and a second petal having a second length, and the first length is different than the second length.

摘要： A method of implanting a prosthetic heart valve includes advancing a prosthetic heart valve to an implantation location within a patient's body, positioning the prosthetic heart valve within a native heart valve annulus, expanding a frame of the prosthetic heart valve from a first contracted configuration to a first expanded configuration, and then contracting the frame to a second contracted configuration. The prosthetic heart valve may be repositioned and then re-expanded from the second contracted configuration to a second expanded configuration. The prosthetic heart valve is preferably released from the delivery apparatus while in the second expanded configuration. Releasing the prosthetic heart valve from the delivery apparatus may result in radial expansion of a flange portion of the prosthetic heart valve.
