Abstract
A method is provided for treating mitral valve regurgitation, including inserting a band around between 90 and 270 degrees of a mitral valve of a heart, including around at least a portion of a posterior cusp of the valve, in a space defined by (a) a ventricular wall, (b) a ventricular surface of the posterior cusp in a vicinity of an annulus of the valve, and (c) a plurality of chordae tendineae of one or more types of chordae tendineae selected from the group consisting of: second-order chordae tendineae and third-order chordae tendineae. The method also includes applying pressure to the posterior cusp by inflating the band.
