Abstract
An assembly and method for effecting the condition of a mitral valve annulus of a heart includes a guide wire configured to be fed into the coronary sinus of the heart, and a mitral valve annulus therapy device configured to be slidingly received on the guide wire and advanced into the coronary sinus of the heart on the guide wire. A guide tube may further be employed for guiding the device into the coronary sinus. An introducer which may be employed for pushing the device into or pulling device out of the heart has a mechanism for releasably locking to the device. This enables substitution of the device if needed. Also, the crossover point of the circumflex artery and coronary sinus may be determined and avoided when the device is deployed.

16. A method of deploying a mitral valve annulus constricting device within the coronary sinus of a heart, the method including the steps of:
-
A. providing an elongated flexible guide wire having a cross sectional dimension;
B. feeding the guide wire into the coronary sinus of the heart;
C. providing an elongated flexible guide tube having an inner lumen, the inner lumen having a cross sectional dimension greater than the cross sectional dimension of the guide wire;
D. feeding the guide tube into the coronary sinus of the heart over the guide wire with the guide wire within the inner lumen of the guide tube;
E. providing a mitral valve annulus device configured to be slidingly received on the guide wire and within the inner lumen of the guide tube, the device including a proximal end;
F. providing a flexible elongated introducer configured to be slidingly received on the guide wire and within the inner lumen of the guide tube, the introducer having a distal end;
G. placing the device onto the guide wire;
H. placing the introducer onto the guide wire;
I. engaging the distal end of the introducer with the proximal end of the device, the engaging step including releasably locking the proximal end of the device to the distal end of the introducer;
J. pushing the device with the introducer in a distal direction along the guide wire and within the guide tube until the device is at least partially encircling the mitral valve within the coronary sinus of the heart; and
K. withdrawing the introducer and the guide tube from the heart;

31. A method of deploying a mitral valve annulus reshaping device within the coronary sinus of a heart, the method including the steps of:
-
inserting a guide wire into the coronary sinus of the heart;
deforming the mitral valve annulus reshaping device from an unstressed shape having a radius smaller than the radius of a mitral valve annulus of the heart to a deformed shape; and
advancing the mitral valve annulus reshaping device on the guide wire and into the coronary sinus into a position such that the device at least partially encircles the mitral valve of the heart. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38)
