Abstract
Abstract The prosthesis comprises a unitary annular vlave body having a pair of leaflets (2, 3) mounted on pivot posts adjacent their outer edges, so as to be pivotted btween a closed position (in which the free edges of the leaflets (2, 3) are contiguous so as to inhibit flow of blood through the valve body) and a fully open position (in which the free edges are parallel to one another so as to permit flow of blood through the valve body). The valve body and the leaflets (2, 3) are each precision moulded, homogenous monolithic vitreous carbon artefacts having an as-moulded surface of optical quality.
