LAMINATED SEALING MEMBER FOR PROSTHETIC HEART VALVE
First Claim
1. An implantable prosthetic valve that is radially collapsible to a collapsed configuration and radially expandable to an expanded configuration, the prosthetic valve comprising:
- 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 having a main portion that encapsulates at least a portion of the frame and an end portion extending from the inflow end of the frame;
wherein 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.

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.

12. A method of making a prosthetic heart valve, comprising:
-
positioning a first layer about a mandrel; positioning a radially expandable frame over the first layer; positioning a second layer over the radially expandable frame; fusing the first and second layers to form a monolithic laminate sealing member such that at least a portion of the frame is encapsulated within the laminate sealing member; and folding an end portion of the laminate sealing member and securing it to a main portion of the laminate sealing member to form a cuff adjacent an inflow end of the frame. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. A transcatheter heart valve, comprising:
-
a radially expandable frame having an inflow end, an outflow end, and a laminate sealing member comprising; a non-fabric inner layer positioned inside of the frame; a non-fabric outer layer positioned outside of the frame; and a fabric layer positioned between the non-fabric inner layer and the non-fabric outer layer, the non-fabric inner and outer layers being fused to one another such that the fabric layer and at least a portion of the frame are encapsulated therebetween; wherein the laminate sealing member further comprises a main portion adjacent the frame and an end portion extending from the inflow end of the frame, the end portion being folded to form a cuff adjacent the inflow end of the frame and secured to the main portion of the laminate sealing member.
