Cardiac valvular prosthesis

摘要: A mechanical-type, bivalve cardiac valvular prosthesis including a support ring defining central opening passing therethrough and pair of relatively rigid leaflets, each having diametrical straight edge curved edge, disposed generally within the opening. The leaflets are pivotably supported on to permit move between an open position, in which parallel axis so that said remains substantially cleared, closed is blocked by leaflets. pivot supports rigidly joined at one end inner surface opposite, hook-shaped, free leaflet associated therewith mounted floating manner pivotable about virtual edges thereof through zone center curvature hook-shaped ends supports.
