An assembly for effecting the condition of a mitral valve annulus includes a
mitral
valve therapy device, a coupling structure carried by the device, a catheter, a
second coupling structure, and a locking member. To implant the device, the device
is first releasably locked to a pushing member by the coupling structures and the
locking member. When the device is positioned within the coronary sinus adjacent
the mitral valve annulus and deployed, the coupling structures may be released
from each other by the release of the locking member.
