Abstract: Provided is a mitral annuloplasty band having a size that allows it to be inserted into the ventricle and a rectangular parallelepiped shape extending in a longitudinal direction thereof, wherein the ratio of the width and height is in a range of 1:2 to 1:8. Therefore, a portion of the mitral annulus adjacent to the posterior leaflet can be lifted up to a mitral annuloplasty band located at the wall of the left atrium and fixed thereto to recover the function of the mitral valve, without disturbing movement of the mitral valve and movement of the mitral annulus and the left ventricle adjacent thereto.

Abstract: The present invention is an apparatus designed to effectuate restoration of normal aortic valvular function where there is aortic valvular regurgitation, either primary or secondary to diseases of the aorta, such as aortic aneurysm, aortic dissection, rheumatic aortic disease, annuloaortic ectasia, etc. are present. The present invention also provides methods of using the apparatus to treat conditions of abnormal aortic valvular function.

Abstract: The present invention is an apparatus designed to effectuate restoration of normal aortic valvular function where there is aortic valvular regurgitation either primary or secondary to diseases of the aorta such as aortic aneurysm, aortic dissection, rheumatic aortic disease annuloaortic ectasia and etc. is present. The present invention provides an apparatus for repairing aortic annulus composed of (1) a band type inner stabilizer (sometimes ring type inner stabilizer) which is implanted in the true aortic lumen to fix the aortic annular diameter and (2) an outer felt stabilizer which is implanted on the outside surface of aorta to support the inner stabilizer.
