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 close 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.

19. A method of delivering a heart valve prosthesis to an anatomical site, the method comprising the steps of:
-
introducing a heart valve prosthesis into the heart through a catheter, the heart valve prosthesis comprising a docking station comprising a wire frame defining a lumen and a diaphragm comprising a plurality of leaflets and adapted to have an open position and a close position; deploying the docking station; introducing a replacement heart valve into the lumen of the docking station through a catheter, the replacement heart valve comprising a valve frame and a plurality of valve members; and deploying the replacement heart valve within the lumen of the docking station so that the leaflets of the diaphragm are pressed between the wire frame of the docking station and the valve members of the replacement heart valve. - View Dependent Claims (20, 21)
