    摘要： A novel catheter-based system that ligates the left atrial appendage (LAA) on the outside of the heart, preferably using a combination of catheters and/or instruments, e.g., a guide catheter inserted into the interior of the left atrial appendage that may assist in locating the left atrial appendage and/or assist in the optimal placement of a ligature or constricting element on the outside of the appendage, and a ligating catheter and/or instrument outside the heart in the pericardial space to set the ligature or constricting element at the neck of the left atrial appendage.

    摘要： A method and apparatus for reducing mitral regurgitation. The apparatus is inserted into the coronary sinus of a patient in the vicinity of the posterior leaflet of the mitral valve, the apparatus being adapted to straighten the natural curvature of at least a portion of the coronary sinus in the vicinity of the posterior leaflet of the mitral valve, whereby to move the posterior annulus anteriorly and thereby improve leaflet coaptation and reduce mitral regurgitation.

    摘要： Devices and methods for performing intravascular procedures without cardiac bypass include embodiments of temporary filter devices, temporary valves, and prosthetic valves. The temporary filter devices have a cannula which provides access for surgical tools for effecting repair of cardiac valves. The cannula may have filters which prevent embolitic material from entering the coronary arteries and aorta. The valve devices may also have a cannula for insertion of the valve into the aorta. The valve devices expand in the aorta to occupy the entire flow path of the vessel and operate to prevent blood flow and to permit flow through the valve. The prosthetic valves include valve fixation devices which secure the prosthetic valve to the wall of the vessel. The prosthetic valves are introduced into the vascular system in a compressed state, advanced to the site of implantation, and expanded and secured to the vessel wall.

    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.
