DEVICES, SYSTEMS, AND METHODS FOR RESHAPING A HEART VALVE ANNULUS
First Claim
1. A system comprisingan implant sized and configured for placement within a heart chamber,a guide wire sized and configured for deployment in an intravascular path that extends from a first vascular access into the heart chamber and from the heart chamber to a second vascular access site different than the first vascular access site, the guide wire having a first end extending beyond the first vascular access site and a second end extending beyond the second vascular access site, anda connector to connect an end of the implant to one end of the guide wire such that pulling on the other end of the guide wire pulls the implant along at least a portion of the intravascular path into the heart chamber.

Abstract
Implants or systems of implants and methods apply a selected force vector or a selected combination of force vectors within or across the left atrium, which allow mitral valve leaflets to better coapt. The implants or systems of implants and methods make possible rapid deployment, facile endovascular delivery, and full intra-atrial retrievability. The implants or systems of implants and methods also make use of strong fluoroscopic landmarks. The implants or systems of implants and methods make use of an adjustable implant and a fixed length implant. The implants or systems of implants and methods may also utilize a bridge stop to secure the implant, and the methods of implantation employ various tools.

3. A system comprising
a bridge element sized and configured to be implanted within the left atrium between the great cardiac vein and the interatrial septum, the bridge element having opposite ends, a guide wire sized and configured to be deployed in an intravascular path that extends from a first vascular access site through an interatrial septum into the left atrium and from the left atrium through a great cardiac vein to a second vascular access site that is different than the first vascular access site, the guide wire having a first end extending beyond the first vascular access site and a second end extending beyond the second vascular access site, a connector to connect an end of the bridge element to one end of the guide wire such that pulling on the other end of the guide wire pulls the bridge element along at least a portion of the intravascular path into the left atrium, a posterior bridge stop sized and configured to be secured to an end of the bridging element to abut against venous tissue within the great cardiac vein, and an anterior bridge stop sized and configured to be secured to the bridging element to abut against tissue on the interatrial septum within the right atrium.
