Abstract
A device for engaging a heart valve prosthesis during implantation includes a mechanism for attaching the device to the heart valve prosthesis. The heart valve prosthesis includes a circular valve body having an annulus with a substantially annular aperture therein. At least one movable occluder is carried in the aperture and is movable between an open position and a closed position. The attachment mechanism includes a member which couples to the circular valve body thereby affixing the device to the heart valve prosthesis. The thickness of the device which extends in a direction above the heart valve prosthesis is reduced. The device is selectively removable from the heart valve prosthesis following implantation of the prosthesis in the heart tissue annulus of a patient.
