Abstract:
1. A prosthetic heart valve comprising: a collapsible and expandable annular frame that is configured to be collapsed to a radially collapsed state for mounting on a delivery apparatus and expanded to a radially expanded state inside the body, the frame having an inflow end, an outflow end, and a longitudinal axis extending from the inflow end to the outflow end, the frame comprising a plurality of struts defining a plurality of cells; and a collapsible and expandable valve member mounted within the annular frame; and a collapsible and expandable annular sealing member having an inflow end and an outflow end, the sealing member being coupled to the frame such that when the frame is in its radially collapsed state, the sealing member can be placed in a delivery orientation in which the sealing member is radially collapsed and extends from the inflow end of the frame in a direction away from the outflow end of the frame, and such that a proximal pulling force on the sealing member causes the sealing member to be displaced axially relative to the frame toward the outflow end of the frame in a direction parallel to the longitudinal axis to an operative orientation in which the outflow end of the sealing member is moved closer to the outflow end of the frame and the inflow end of the sealing member is moved closer to the inflow end of the frame and the sealing member covers at least a portion of the cells of the frame.
