摘要： A device for reshaping a mitral valve annulus (25), said device being elongate and having such dimensions as to be insertable into a coronary sinus (24). The device comprises fixing means (22, 23; 22a, 23a) for fixing the ends of the device within the coronary sinus (24); anda shape changing member (20a; 7; 7a; 9) extending between the fixing means (22, 23; 22a, 23a). The shape changing member (20a; 7; 7a; 9) includes a plurality of adjacent structural cells. The device includes resorbable delay means (21 a; 8; 8a; 10) that in a first configuration retrains at least two of said plurality of adjacent structural elements in a first, relatively elongate state of shape (K; D; E) and wherein the delay means in a second configuration releases said at least two adjacent structural elements to assume a second, relatively shortened state of shape (K'; D'; E'), thereby reducing a length of the shape-changing member (20a; 7; 7a; 9). The delay means (21 a; 8; 8a; 10) moves from its first configuration to its second configuration upon resorbtion of the delay means.

摘要： The invention is device and method for reducing regurgitation through a mitral valve. The device and method is directed to an anchor portion for engagement with the heart wall and an expandable valve portion configured for deployment between the mitral valve leaflets. The valve portion is expandable for preventing regurgitation through the mitral valve while allowing blood to circulate through the heart. The expandable valve portion may include apertures for reducing the stagnation of blood. In a preferred configuration, the device is configured to be delivered in two-stages wherein an anchor portion is first delivered and the valve structure is then coupled to the anchor portion. In yet another embodiment, the present invention provides a method of forming an anchor portion wherein a disposable jig is used to mold the anchor portion into a three-dimensional shape for conforming to a heart chamber.

摘要： In one embodiment, the present invention provides a prosthesis that can be implanted within a heart to at least partially block gaps that may be present between the two mitral valve leaflets. In one preferred embodiment, the prosthesis includes an anchoring ring that expands within the left atrium to anchor the prosthesis and a pocket member fixed to the anchoring ring. The pocket member is positioned within the mitral valve, between the leaflets so that an open end of the pocket member is positioned within the left ventricle. When the mitral valve is open, blood flows past the pocket member, maintaining the pocket member in a collapsed state. When the mitral valve closes, the backpressure of the blood pushes into the pocket member, expanding the pocket member to an inflated shape. The mitral valve leaflets contact the expanded pocket member, allowing the prosthesis to block at least a portion of the openings between the leaflets, thereby minimizing regurgitated blood flow into the left atrium.
