Problems solved by technology

[0019] Second, blood volume going to the atria reduces blood volume advancing into the aorta, reducing cardiac output
The problem with surgical treatment is the significant harm it does to these long-term patients, who have high morbidity and mortality associated with surgical repair

[0133] While the disclosure of the invention is detailed and specific to enable those skilled in the art to practice the invention, the specific embodiments disclosed herein are merely examples of the invention embodied in other specific structures. While a preferred embodiment of the invention has been described, modifications of detail may be made without departing from the invention as defined by the claims.

[0134] I. Transseptal implants for direct shortening of the short axis of the heart valve annulus

[0135] A. Implant structure

[0136] Figure 10A to Figure 10C An embodiment of an implant 10 is shown sized and configured to extend through the left atrium in a generally anterior-to-posterior direction, thereby spanning the mitral valve annulus. The implant 10 includes a spanning region or bridge 12 having a rear axle stop region 14 and an anterior axle stop region 16 .

[0137] Posterior bridge stop area 14 is sized and configured to allow bridge 12 to be positio...

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.

Description

technical field [0001] The present invention relates to devices, systems, and methods for improving heart valve function, eg, in the treatment of mitral regurgitation. Background technique [0002] I. Healthy Heart Anatomy [0003] heart (see figure 1 ) is slightly larger than a clenched fist. The heart is a bilateral (left and right) self-regulating muscle pump with multiple parts working together to push blood to all parts of the body. The right side of the heart receives deoxygenated ("venous") blood from the body through the superior and inferior vena cava and pumps it through the pulmonary artery to the lungs for oxygenation. The left side receives oxygen-rich ("arterial") blood from the lungs through the pulmonary veins and pumps it to the aorta for distribution to the body. [0004] The heart has four chambers, two on each side -- the right and left atria, and the right and left ventricles. The atria are chambers that receive blood, which pumps it into the ventri...
