Apparatus is provided, including a prosthetic device, having a single flow field therethrough, adapted for implantation in a subject, and shaped so as to define a fluid inlet and a diverging section, distal to the fluid inlet. The prosthetic device includes a plurality of axially-extending struts (112) which extend along at least a portion of the diverging section and diverge outwardly, such that distal ends of the struts are spaced further from one another than proximal ends of the struts thoughout a cardiac cycle of the subject. The diverging section includes a diverging envelope (111), coupled to the struts, which is adapted to assume an open position thereof during systole, permitting blood flow through the device, and which is adapted to collapse to a closed position thereof during diastole, inhibiting blood flow through the device. |
