The present invention provides devices for treating functional mitral regurgitation and methods of use thereof. The devices translocate a subject's mitral valve in an apical direction. The devices thereby treat mitral regurgitation while preserving a subject's original mitral valve and chordae tendinae.
Claims56
An apparatus comprising:
- a ring-shaped body having an annulus portion and a leaflet portion axially spaced from the annulus portion,
- the annulus portion having an annulus end having a perimeter and being configured to be attached to an annulus of a native heart valve from which a leaflet of the native heart valve has been separated,
- leaflet portion having a leaflet end having a perimeter equal to or larger than the annulus portion perimeter and being configured to be attached to the native heart valve leaflet and thereby to connect the native heart valve leaflet to the native heart valve annulus.

A method of repairing a native heart valve having a native annulus and native leaflets extending from the native annulus, comprising:
- separating a native leaflet from the native annulus, the separated native leaflet having an annulus edge at which the native leaflet was joined to the annulus and the native annulus having a leaflet edge at which the annulus was joined to the leaflet edge of the native leaflet;
- attaching to the leaflet edge of the native annulus an annulus end of an annulus portion of a ring-shaped body, the annulus end having a perimeter;
- and
- attaching to the annulus edge of the native leaflet a leaflet end of a leaflet portion of the ring-shaped body, the leaflet portion being axially spaced from the annulus portion, the leaflet end having a perimeter equal to or larger than the perimeter of the annulus end.
