Mitral valve therapy device, system and method
First Claim
1. A method of determining a crossover point of a circumflex artery and coronary sinus of a heart, the method including the steps of:
- inserting a first elongated flexible rod into the coronary sinus, the first rod being visible under X ray fluoroscopy;
inserting a second elongated flexible rod into the circumflex artery, the second rod being visible under X ray fluoroscopy; and
subjecting the heart to X ray fluoroscopic examination to determine the crossover point of the first and second rods.

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.

2. A method of deploying a mitral valve annulus therapy device within a coronary sinus of a heart, the method including the steps of:
-
inserting a first wire into a circumflex artery of the heart, the first wire being visible under X ray fluoroscopy; inserting a second wire into the coronary sinus of the heart, the second wire being visible under X ray fluoroscopy; subjecting the heart to X ray fluoroscopic examination to visualize a crossover point of the first and second wires; and deploying an elongated mitral valve annulus therapy device within the coronary sinus in a position such that a distal end of the device is proximal to the crossover point of the first and second wires. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10)
