Cardiac valve downsizing device and method

A kit for repairing and/or replacing a mitral valve includes a mitral valve prosthesis and a loop-shaped element with a proximal end, a distal end, and a curved body. A proximal portion of the curved body is sized for positioning on an atrial side of the mitral valve and a distal portion of the curv...

Beschreibung
Zusammenfassung:	A kit for repairing and/or replacing a mitral valve includes a mitral valve prosthesis and a loop-shaped element with a proximal end, a distal end, and a curved body. A proximal portion of the curved body is sized for positioning on an atrial side of the mitral valve and a distal portion of the curved body is sized for positioning on a ventricular side of the mitral valve. The distal portion has a first curved region with a radius of curvature that is larger than the radius of curvature of a second curved region so that the distal portion passes between heart muscle wall and chordae and circumflex the chordae of the mitral valve when the distal portion is rotated into place at the ventricular side of the native mitral valve.
