MITRAL VALVE THERAPY DEVICE, SYSTEM AND METHOD

摘要

An assembly (50) and method for effecting the condition of a mitral valve annulus (20) of a heart (10) includes a guide wire (52) configured to be fed into the coronary sinus (14) of the heart (10), and a mitral valve annulus therapy device (30) configured to be slidingly received on the guide wire (52) and advanced into the coronary sinus (14) of the heart (10) on the guide wire (52). A guide tube (54) may further be employed for guiding the device (30) into the coronary sinus (14). An introducer (56) which may be employed for pushing the device (30) into or pulling device out of the heart (10) has a mechanism for releasably locking to the device (30). This enables substitution of the device (30) if needed. Also, the crossover point (19) of the circumflex artery (17) and coronary sinus (14) may be determined and avoided when the device (30) is deployed.
