    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： Device for treating mitral insufficiency and a method for producing the device. The device comprises a proximal stent section (222); a distal stent section (224); a central stent section (226) interconnecting said proximal stent section (222) and said distal stent section (226); and at least one biodegradable structure (228), disposed on the central stent section (226). Said proximal stent section (222) and said distal stent section (226) being radially expandable by deployment of said device. Moreover said biodegradable structure (228) is arranged to retain the central section (226) in a contracted shape for a predetermined period after deployment of the device.

    摘要： The invention refers to a device for treatment of mitral annulus dilatation without the need for cardiopulmonary bypass, comprising an elongate body (8) made of memory metal which has a memory of an original shape, the elongate body having such dimensions as to be insertable through the venous system and into the coronary sinus (5) by a catheter technique and having two states, in a first of which the elongate body has a shape that is adaptable to the shape of the coronary sinus, and to the second of which the elongate body is transferable from the said first state by returning toward the original shape and assuming a reduced radius of curvature, whereby the radius of curvature of the coronary sinus is reduced as well as the circumference of the mitral valve annulus, when the elongate body is positioned in the coronary sinus.
