Devices, systems, and methods for reshaping a heart valve annulus, including the use of an adjustable bridge implant system
First Claim
1. An implant system comprising a bridging element sized and configured to span a left atrium between a great cardiac vein and an interatrial septum, a posterior bridge stop coupled to the bridging element and that abuts venous tissue within the great cardiac vein, an anterior bridge stop coupled to the bridging element and that abuts interatrial septum tissue in the right atrium, and a bridging element adjustment mechanism to shorten and/or lengthen the bridging element.

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 adjustability and retrievability years after implant. 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 an adjustable bridge stop to secure the implant, and the methods of implantation employ various tools.
