    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： 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 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.
