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.

10. A system for delivering a device to a given location within a heart, the system comprising:
-
a first catheter having a proximal end and a distal end, the distal end of the first catheter configured to pass through the left atrium-the mitral valve and into the left ventricle of the heart; a second catheter having a proximal end and a distal end, the distal end of the second catheter configured to pass through the aorta and the aortic valve; and a device to be delivered within a heart, including a first mount and a second mount, wherein the mounts selectively secure the device to at least one of the distal ends of the first and second catheters in order to selectively connect at least one of the first and second catheters to the device separately or at the same time; whereby the device can be positioned relative to a given location within the heart by selectively retracting one of the first catheter and the second catheter while at least one of the first catheter and second catheter is connected to the device so as to move the device through the heart. - View Dependent Claims (11)

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; delivering the device within the heart as attached to one of the first catheter and the second catheter; 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; delivering the device as attached to one of the first catheter and the second catheter; 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)
