Prosthetic heart valve leaflet assemblies and methods
Abstract
A prosthetic heart valve comprises an annular frame comprising a plurality of interconnected struts, wherein the frame is radially compressible and expandable between a radially compressed state and a radially expanded state. A plurality of leaflets are situated within the frame, each leaflet comprising a main body, two opposing commissure tabs arranged on opposite sides of the main body and two opposing sub-commissure tabs arranged on opposite sides of the main body. Each commissure tab of a leaflet is paired with an adjacent commissure tab of an adjacent leaflet to form a commissure that is coupled to the frame. Each sub-commissure tab is paired with an adjacent sub-commissure tab of an adjacent leaflet and connected thereto, wherein each pair of sub-commissure tabs extends radially inwardly relative to the frame.
