Method and apparatus for resecting and replacing an aortic valve
First Claim
1. A method for delivering a device to a given location within a heart, the method comprising:
- 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;
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.

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.

11. An apparatus for delivering a device to a given location within a heart, the apparatus comprising:
-
a first catheter and a second catheter, the first catheter having a proximal end and a distal end, the distal end of the first catheter configured to pass through the left atrium of the heart, through the mitral valve into the left ventricle, the second catheter configured to pass through the aorta and the aortic valve, and at least one of the first catheter and the second catheter carrying the device; and connection means for selectively connecting the distal end of the first catheter and distal end of the second catheter to one another; wherein the first catheter and the second catheter are connected together such that the device is positioned relative to the given location within the heart by selectively retracting one of the first catheter and the second catheter so as to move the connected catheters through the heart. - View Dependent Claims (8)

12. A method for delivering a device to a given location within a heart, the method comprising:
-
advancing a first catheter through the left atrium of the heart, through the mitral valve and into the left ventricle; advancing a second catheter through the aorta toward the heart, advancing the second catheter through the aortic valve; connecting the first catheter and the second catheter together; and retracting one of the first catheter and the second catheter in a direction opposite to one another so as to position the device relative to the given location within the heart.

13. A method for positioning a device at a given location within a heart, the method comprising:
-
inserting a distal end of a first catheter into a left atrium of the heart; inserting a distal end of a second catheter into an aorta toward the heart; advancing at least one of the distal end of the first catheter and the distal end of the second catheter through the heart to position the distal end of the first catheter and the distal end of the second catheter adjacent to one another; attaching the first catheter and the second catheter to one another; retracting one of the first catheter and the second catheter, with the device in attachment to one of the first catheter and the second catheter, so as to position the device adjacent to the given location within the heart. - View Dependent Claims (14, 15, 16, 17, 18, 19)
