System and method to effect mitral valve annulus of a heart

DETAILED DESCRIPTION The invention provides an assembly for effecting the condition of a mitral valve annulus of a heart.
The assembly includes a mitral valve therapy device that reshapes the mitral valve annulus of the heart when placed within the coronary sinus of the heart adjacent the mitral valve annulus.
The mitral valve therapy device has a proximal end including a coupling structure.
The assembly further includes a catheter having a lumen that directs the mitral valve therapy device into the coronary sinus of the heart, a second coupling structure that is lockable on the device coupling structure, and a locking member that locks the device coupling structure to the second coupling structure and that releases the device coupling structure from the second coupling structure.
The assembly may further include a pusher member that pushes the device through the catheter lumen.
The pusher member has a distal end that engages the device proximal end.
The pusher member may carry the second coupling structure at the distal end of the pusher member.
The device coupling structure may comprise a hoop structure.
The second coupling structure may also comprise a hoop structure.
The locking member comprises a pin that extends through the hoop structures to lock the coupling structures together and that is retractable to release the hoop structures.
The catheter has a distal end and the pin is preferably long enough to extend through the distal end of the catheter.
The pusher member may be an elongated coil.
The device coupling structure and the second coupling structure may alternatively comprise a pair of interlocking structures and the locking member may comprise a slide-lock sheath closely fitted to the interlocking structures.
The interlocking structures and the slide-lock sheath may be tubular.
The pusher member has a distal end that engages the device proximal end, and carries the second coupling structure.
The locking member may further include a tether that extends from the slide-lock sheath to and through the catheter lumen to permit the tether to pull proximally on the slide-lock sheath for releasing the interlocking structures
