HEART VALVE HOLDER FOR CONSTRICTING THE VALVE COMMISSURES AND METHODS OF USE

摘要

An improved holder, system and method for implanting a tissue-type prostheti c heart mitral valve that constricts the commissure posts of the valve and allows the user to detach the handle of the holder prior to withdrawing the holder itself. The ability to remove the handle allows a surgeon greater access to suturing the prosthetic valve to the mitral annulus. The holder ma y include two relatively movable plates, one of which attaches to the valve sewing on the inflow end of the valve ring and the other which attaches via sutures to the valve commissures on the outflow end. Separation of the plate s places the sutures in tension and constricts the commissures. An adjusting member or adapter is interposed between the handle and holder to enable separation of the two plates and removal of the handle. The adjusting member or adapter may be packaged with the valve and holder combination, or may be sold as a separate unit, possibly with the handle, so that prior art holders can be retrofit.
