First Claim
Patent Images
1. An assembly for effecting the mitral valve annulus of a heart comprising:
- 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 having a proximal end including a coupling structure;
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, the device coupling structure and the second coupling structure comprising a pair of interlocking structures;
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 locking member comprising a slide-lock sheath closely fitted to the interlocking structures; and
a pusher member that pushes the device through the catheter lumen, the pusher member having a distal end that engages the device proximal end, and wherein the pusher member carries the second coupling structure at the distal end of the pusher member.

Abstract
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.
