PERCUTANEOUS MITRAL ANNULPLASTY WITH CARDIAC RHYTHM MANAGEMENT
First Claim
Patent Images
1. A medical apparatus, for remodeling a mitral valve annulus adjacent to the coronary sinus, comprising:
- an elongate body sized for implantation at least partially within the coronary sinus, the elongate body having a proximal end and a distal end and being movable between a first configuration for transluminal delivery to at least a portion of the coronary sinus and a second configuration for remodeling the mitral valve annulus from within the coronary sinus, the elongate body in the second configuration being configured to exert, while residing completely within the vasculature system, a force against a wall of the coronary sinus sufficient to reduce mitral regurgitation by a therapeutically effective amount;
a forming element attached to the elongate body at a point of attachment for manipulating the elongate body between the first configuration and the second configuration, wherein the forming element is slidably contained within the elongate body between the attachment point and the proximal end; and
a cardiac pacing electrode, carried by the elongate body and configured to be implanted in the coronary sinus with the elongate body;
wherein a portion of the forming element is configured to be removable after implantation of the elongate body within the coronary sinus while a remaining portion of the forming element is contained within the elongate body;
wherein the cardiac pacing electrode remains with the elongate body in the coronary sinus (i) after the elongate body is manipulated between the first configuration and the second configuration, (ii) after implantation of the elongate body within the coronary sinus, and (iii) after the portion of the forming element is removed from the coronary sinus.

Abstract
A minimally invasive method of performing mitral annuloplasty is disclosed. An implantable device is positioned within the coronary sinus and tightened around the mitral annulus. Mitral valve regurgitation is monitored before, during, and/or after the tightening step. An on-going drug therapy may be determined, taking into account post-implantation hemodynamic function.

23. A medical apparatus, for treating a mitral valve of a patient, comprising:
-
an elongate body sized and configured to be implanted at least partially within the coronary sinus of a patient'"'"'s heart, the elongate body being movable between a delivery configuration and a deployment configuration, the elongate body in the deployment configuration, when implanted at least partially within the coronary sinus, being configured to apply a force against a wall of the coronary sinus sufficient to reduce mitral regurgitation by a therapeutically effective amount; a forming element coupled with the elongate body for manipulating the elongate body between the delivery configuration and the deployment configuration, the forming element having a first portion that is configured to be removed from the patient after implantation of the elongate body in the coronary sinus; and a cardiac electrode, carried by the elongate body and configured to remain with the elongate body after the first portion of the forming element is removed from the patient after implantation of the elongate body in the coronary sinus. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30)

31. A medical apparatus, for treating a mitral valve of a patient, comprising:
-
an elongate body that, when implanted within the coronary sinus of the patient'"'"'s heart, is configured to exert a force against a wall of the coronary sinus sufficient to reduce mitral regurgitation by a therapeutically effective amount; a forming element coupled with and shaping the elongate body, the forming element having a first portion that is removed from the patient after implantation of the elongate body in the coronary sinus; and a cardiac electrode, in or on the elongate body, configured to maintain electrical coupling with a cardiac rhythm management device after implantation of the elongate body in the coronary sinus.
