Abstract

Abstract A flexible leaflet heart valve (1) to replace natural aortic or pulmonary valves of the heart, includes a frame (3) and flexible leaflets (2) attached to the frame (3). Each flexible leaflet (2) forms part of a surface of revolution having its axis of revolution substantially orthogonal to the direction of blood flow through the valve (1). The valve (1) has improved opening characteristics under low flow conditions, and allows a large range of leaflet geometries for the same size valve.
