Abstract

A mechanical heart valve for implantation in a heart of a patient includes an orifice body having an outer circumference and defining a lumen for blood flow therethrough. At least one leaflet carried in the lumen of the orifice body is movable between an open position, allowing flow through the lumen, and a closed position blocking flow through the lumen. A flange ring around the outer circumference of the orifice body includes a plurality of suture holes defined therein. The suture holes are adapted for receiving a suture and thereby attaching the heart valve to tissue of the heart.
