Embodiment Construction

[0065] I. Cardiac Physiology

[0066] The left ventricle LV of the normal heart H in contraction is in figure 1 show. The left ventricle LV is contracting, and blood flows outward through the tricuspid (aortic) valve AV in the direction of the arrow. Since the mitral valve is configured as a "check valve" that prevents regurgitation when the pressure in the left ventricle is higher than the left atrium LA, it can prevent blood from reversing or "backflowing" through the mitral valve MV. The mitral valve MV includes a pair of leaflets with free edges FE that are evenly butted to close, such as figure 1 Shown. The opposite end of the leaflet LF is attached to the surrounding heart structure along an annular area called the annulus AN. The free edge FE of the valve leaflet LF is fixed to the lower part of the left ventricle LV by chordae CT (hereinafter referred to as tendon), which includes a plurality of branch tendons fixed on the lower surface of each leaflet LF. The tendon...

Abstract

The invention provides devices, systems and methods for tissue approximation and repair at treatment sites. The devices, systems and methods of the invention will find use in a variety of therapeutic procedures, including endovascular, minimally-invasive, and open surgical procedures, and can be used in various anatomical regions, including the abdomen, thorax, cardiovascular system, heart, intestinal tract, stomach, urinary tract, bladder, lung, and other organs, vessels, and tissues. The invention is particularly useful in those procedures requiring minimally-invasive or endovascular access to remote tissue locations, where the instruments utilized must negotiate long, narrow, and tortuous pathways to the treatment site.; In addition, many of the devices and systems of the invention are adapted to be reversible and removable from the patient at any point without interference with or trauma to internal tissues.

Description
