摘要: 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.

摘要: A prosthetic device includes a main body, a first anchor, a second anchor, a first anchor spreader, and a second anchor spreader. The first anchor is coupled to the main body such that a spring force of the first anchor biases the first anchor toward the main body. The second anchor is coupled to the main body such that a spring force of the second anchor biases the second anchor against the main body. The first anchor spreader is coupled to the first anchor such that applying a force to the first anchor spreader moves the first anchor away from the main body against the spring force of the first anchor. The second anchor spreader is coupled to the second anchor such that applying a force to the second anchor spreader moves the second anchor away from the main body against the spring force of the second anchor.

摘要: A prosthetic valve assembly includes a support structure and a valve component. The support structure includes a first frame and a sealing member. The first frame includes a lumen extending between inflow and outflow ends. The sealing member extends inwardly into the lumen of the first frame and includes a first end wall defining a first orifice, a second end wall axially spaced from the first end wall and defining a second orifice, and an inner sleeve extending axially from the first end wall to the second end wall and spaced radially inwardly from the first frame. The valve component includes a second frame and a valve structure supported inside of the second frame for permitting blood flow through the valve component in one direction and blocking blood flow in the opposite direction. The valve component is configured to expand within and engage the inner sleeve of the sealing member.

摘要: A prosthesis can be configured to grasp intralumenal tissue when deployed within a body cavity and prevent axial flow of fluid around an exterior of the prosthesis. The prosthesis can include an expandable frame configured to radially expand and contract for deployment within the body cavity and a valve body. The expandable frame can include a frame body and a supplemental frame. The valve body can include a plurality of leaflets and one or more intermediate components. The one or more intermediate components can couple at least a portion of the leaflets to the expandable frame. The prosthesis can include an annular flap positioned around an exterior of the expandable frame.

摘要: 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.

摘要: 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.

摘要: 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.
