Abstract
Abstract An assembly for effecting the condition of a mitral valve of a heart includes a mitral valve therapy device, a guide wire, and a guide tube. The mitral valve therapy device is configured to reshape the mitral valve annulus of the heart when placed within the coronary sinus adjacent the mitral valve annulus. The guide wire is configured to be fed into the coronary sinus of the heart adjacent the mitral valve annulus. The guide tube has a distal end, a proximal end, and a lumen extending between the distal end and the proximal end. The guide tube further includes a side port, intermediate the distal and proximal ends which communicates with the lumen. This permits the guide tube to be slidingly received on the guide wire with the guide wire extending from the distal end, through the lumen, and out the side port. In use, the guide tube is slid along the guide wire into the coronary sinus. The mitral valve therapy device is then delivered by the guide tube into the coronary sinus adjacent the mitral valve annulus.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
179 words
An assembly for effecting the condition of a mitral valve annulus of a heart comprising: a mitral valve therapy device configured to reshape the mitral valve annulus of the heart when placed within the coronary sinus adjacent the mitral valve annulus; a guide wire configured to be fed into the coronary sinus of the heart adjacent the mitral valve annulus; and a guide tube having a distal end, a proximal end, and a lumen extending between the distal end and the proximal end, the guide tube further including a side port, intermediate the distal end and the proximal end and communicating with the lumen, to permit the guide tube to be slidingly received on the guide wire with the guide wire extending from the distal end, through the lumen, and out the side port, whereby the guide tube is slidable along the guide wire to a position adjacent the mitral valve annulus within the coronary sinus and the mitral valve therapy device is guidable within the guide tube for placement in the coronary sinus adjacent the mitral valve annulus.
Claim 2
Dependent Claim
179 words
An assembly for effecting the condition of a mitral valve annulus of a heart comprising: a mitral valve therapy device configured to reshape the mitral valve annulus of the heart when placed within the coronary sinus adjacent the mitral valve annulus; a guide wire configured to be fed into the coronary sinus of the heart adjacent the mitral valve annulus; and a guide tube having a distal end, a proximal end, and a lumen extending between the distal end and the proximal end, the guide tube further including a side port, intermediate the distal end and the proximal end and communicating with the lumen, to permit the guide tube to be slidingly received on the guide wire with the guide wire extending from the distal end, through the lumen, and out the side port, whereby the guide tube is slidable along the guide wire to a position adjacent the mitral valve annulus within the coronary sinus and the mitral valve therapy device is guidable within the guide tube for placement in the coronary sinus adjacent the mitral valve annulus.
