Tri-composite, full root, stentless valve



Tri-composite, full root, stentless valve



Official Gazette of the United States Patent & Trademark Office Patents 1257(1), Apr 2



A bioprosthetic heart valve is disclosed. In a first aspect of the invention, a prosthetic heart valve comprises three mammalian heart valve leaflets, each valve leaflet including a full root length of tissue, the valve leaflets being affixed to one another to define a fluid flow passage, the fluid flow through which may be governed by the valve leaflets. In a second aspect the heart valve comprises a plurality of heart valve leaflets affixed to one another to define a fluid flow passage, the fluid flow through which may be governed by the valve leaflets; and a permanent trimming guide on at least one of the plurality of valve leaflets. In yet a third aspect of the invention, a bioprosthetic heart valve comprises a plurality of assembled parts, wherein the assembled parts are sutured together by hidden and locking stitches.
