US Classification:

623 211, 623 236

Abstract:

A method and apparatus for reducing mitral regurgitation. The apparatus is inserted into the coronary sinus of a patient in the vicinity of the posterior leaflet of the mitral valve, the apparatus being adapted to straighten the natural curvature of at least a portion of the coronary sinus in the vicinity of the posterior leaflet of the mitral valve, whereby to move the posterior annulus anteriorly and thereby improve leaflet coaptation and reduce mitral regurgitation.

Abstract:

A fixation band for affixing a prosthetic heart valve to tissue, the fixation band comprising: a structure having a proximal end and a distal end in opposition to one another, and a lateral region between the proximal end and the distal end, wherein the prosthetic heart valve is attached to one of the proximal end and the distal end of the structure; a plurality of barbs selectively configurable between a first position and a second position, the barbs being contained within a peripheral boundary of the lateral region of the structure in the first position, and the barbs being extended from the peripheral boundary of the lateral region of the structure in the second position; and an actuator for selectively moving the plurality of barbs between the first position and the second position. A fixation band for affixing a prosthetic heart valve to tissue, the fixation band comprising: a proximal annular portion and a distal annular portion selectively positioned relatively to one another, the proximal annular portion and the distal annular portion each having a proximal side and a distal side, the proximal side of the distal annular portion and the distal side of the proximal annular portion being oriented toward one another, and the prosthetic heart valve being attached to one of the distal side of the distal annular portion and the proximal side of the proximal annular portion; a plurality of staples configured between the distal side of the proximal annular portion and the proximal side of the distal annular portion; and a compression device in attachment to the proximal annular portion and the distal annular portion, the compression device being configured to selectively position the proximal annular member and the distal annular member toward one another so as to compress the plurality of staples therebetween and deploy the plurality of staples into tissue so as to affix the prosthetic heart valve to the tissue.

US Classification:

623 236, 623 211

Abstract:

A method and device for reducing mitral regurgitation. An elongated body is positioned in a coronary sinus of a patient in a vicinity of a heart mitral valve posterior leaflet. The body is adapted to straighten a natural curvature of at least a portion of the coronary sinus in the vicinity of the posterior leaflet to move a posterior annulus anteriorly, which in turn moves the posterior leaflet anteriorly, thereby to improve leaflet coaptation.
