Abstract
The present teachings relate to a heart valve prosthesis. The heart valve prosthesis includes a docking station (77) having a wire frame defining a lumen and a valve frame (91) for positioning within its lumen. The docking station includes a diaphragm (78) adapted to have an open position and a closed position, which provides a temporary control mechanism for preventing free regurgitation during the time period between the deployment of the docking station and the deployment of the valve frame, and a sealing mechanism for preventing paravalvar leakage.
