ABSTRACT:
A multi-leaflet (usually trileaflet) heart valve composed of biocompatible polymer which, in all of its embodiments, simultaneously imitates the structure and dynamics of biological heart valves and avoids promotion of calcification. The valve includes a plurality of flexible leaflets dip cast on a mandrel, which leaflets are then bonded with a bonding agent to the interior surfaces of a plurality of struts on a metal-reinforced prosthetic stent. The leaflets open and close in response to the pumping action of the heart and, due to the design of the leaflets, fatigue resistance of the heart valve is high. The leaflets and the polymer components of the prosthetic stent are manufactured of biocompatible polymers exhibiting intrinsic calcification-resistant properties.
