Abstract
The present disclosure relates to laminated sealing members for prosthetic valves and methods of making the same. In a representative embodiment, an implantable prosthetic valve that is radially collapsible to a collapsed configuration and radially expandable to an expanded configuration comprises an annular frame having an inflow end and an outflow end, a leaflet structure positioned within the frame and secured thereto, and a laminate sealing member comprising an encapsulating material. The laminate sealing member has a main portion that encapsulates at least a portion of the frame and an end portion extending from the inflow end of the frame, and the end portion of the laminate sealing member is folded to form a cuff adjacent the inflow end of the frame and secured to the main portion of the laminate sealing member.
