    摘要： A method for deploying an aortic valve prosthesis includes the steps of: making a first opening leading to the left atrium; passing the 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 cardiac chamber; securing the second manipulation instrument to the valve prosthesis; and using the second manipulation instrument to retract at least a portion of the valve prosthesis out of the cardiac chamber.

    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： A novel system for performing a heart valve annuloplasty. The system involves the use of a plication band. In one embodiment, the annulus of the valve is reduced by constriction of the plication band itself. More particularly, each plication band enters the tissue at two or more points which are spaced from one other by a distance which is dictated by the geometry of the plication band. Subsequent constriction of the plication band causes these points to move toward each other, thereby constricting the tissue trapped between these points and thus reducing the overall circumference of the valve annulus. In a second embodiment, the annulus of the valve is reduced by linking multiple plication bands to one other, using a linkage construct, and then using a shortening of the length of the linkage construct between each plication band so as to gather the tissue between each plication band, whereby to reduce the overall circumference of the valve annulus.
