Abstract
A multi-leaflet cardiovascular valve having a generally annular valve body (1) and at least two leaflets (4, 5) mounted within the valve body such that the leaflets rotate around a central axis (11) and a transverse pivoting axis (12) between an open configuration wherein blood is permitted to flow through the annular valve body and a closed configuration wherein blood is prevented from flowing in at least one direction through the annular valve body. During the open configuration, the leaflets rotate around the flow axis.
