    摘要： A fixation band for affixing a prosthetic heart valve to tissue having proximal and distal annular portions positionable relative to one another, the proximal and distal annular portions each having a proximal and distal sides, the proximal side of the distal annular portion and the distal side of the proximal annular portion being oriented toward one another, and a prosthetic heart valve being attachable to one of the distal side of the distal annular portion and the proximal side of the proximal annular portion; staples configured between the distal side of the proximal annular portion and the proximal side of the distal annular portion; and a compression device operative between the proximal and distal annular portions for selectively positioning the proximal and distal annular members toward one another for compressing the staples therebetween and deploying the staples into tissue so as to affix the prosthetic heart valve to tissue.

    摘要： Apparatus for reducing mitral regurgitation, including a bendable elongated body adapted to be inserted into the coronary sinus of a patient in the vicinity of the posterior leaflet of the mitral valve, the elongated body being adjustable between a first configuration adapted to be delivered into the coronary sinus and a second configuration adapted to exert a force onto the posterior annulus. The body includes a flexible spine having a proximal end and a distal end, and a flexible wire mounted on the spine and having a distal end fixed to the spine proximate to the distal end of the spine, and having a proximal portion extending from the proximal end of the spine. Axial movement of the wire causes a change in the spine from the first configuration to the second configuration to exert the force on the posterior annulus and thereby reduce mitral regurgitation.

    摘要： The present invention comprises a method for deploying an aortic valve prosthesis. This valve prosthesis may include any of the known aortic valves including, but not limited to, stented and unstented bioprosthetic valves, stented mechanical valves, and expandable or self-expanding valves, whether biological or artificial. The method involves the steps of: making a first opening leading to the left atrium; passing a valve prosthesis through the opening and into a cardiac chamber of the left side of the heart using a first manipulation instrument; making a second opening in the arterial system and advancing one end of a second manipulation instrument through the arterial opening and into the aforementioned cardiac chamber; securing the second manipulation instrument to the valve prosthesis; and using the second manipulation instrument to retract at least some portion of the valve prosthesis out of the aforementioned cardiac chamber.
