Abstract

Abstract A method and apparatus for delivering a device to a given location within a heart, the method and apparatus being adapted for: passing a first catheter through the left atrium of the heart, through the mitral valve and into the left ventricle, and passing a second catheter through the aorta toward the heart, one or the other of the first catheter and the second catheter, with the device attached thereto, forming a device-carrying assembly for engagement with the remaining catheter; causing the device-carrying assembly and the remaining catheter to engage one another so as to form a connection therebetween; and retracting one of the device-carrying assembly and the remaining catheter in a direction opposite to the other of the device-carrying assembly and the remaining catheter so as to position the device relative to the given location within the heart.
