Devices, systems, and methods for reshaping a heart valve annulus, including the use of a bridge implant having an adjustable bridge stop
First Claim
1. A bridge stop apparatus comprising:
- a bridge stop housing having a length and a width;
an aperture extending through the length of the bridge stop housing, the aperture sized and configured to allow at least a portion of a bridging element to extend through at least a portion of the length of the aperture, the bridging element having a length capable of bridging at least a portion of the interior of an atrium of a human heart;
a septal member, the septal member having an orifice formed therein, said orifice of sufficient diameter to receive the bridging element slidingly therein; and
an adjustment mechanism coupled to the bridge stop housing, wherein the adjustment mechanism further comprisesa toothed ribbon located within the bridge stop housingsaid adjustment mechanism having a restrained configuration wherein movement of said bridging element is restrained relative to said bridge stop, and an unrestrained configuration wherein movement of said bridging element is unrestrained relative to said bridge stop, said adjustment mechanism movable between said unrestrained and said restrained configuration, and subsequently from said restrained configuration back to said unrestrained configuration.

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.
