SEALING MEMBER FOR PROSTHETIC HEART VALVE

Abstract:

A prosthetic heart valve can include a frame, a valve component, a sealing member, and a retaining member. The frame can be radially compressible and expandable between a radially-compressed configuration and a radially-expanded configuration. The valve component can be disposed within and coupled to the frame and have a plurality of leaflets. The sealing member can have a plurality of ribs and a plurality of connectors. The ribs can be coupled to and extend radially outwardly from the frame when the frame is in the radially-expanded configuration. The connectors can be coupled to and extend radially between the frame and the ribs. The sealing member can be configured to reduce or prevent perivalvular leakage around the prosthetic heart valve. The retaining member can be coupled to the frame and the sealing member and can retain the sealing member at a desired spacing relative to the frame.
