Abstract
A stentless heart valve assembled from autologous tissue is provided. The tissue is cut into a rectangular shape, folded, and stapled at several locations to form the cusps of the valve. The outer walls of the valve are pinched at the midpoint of each cusp to prevent the cusps from adhering to the valve walls. The ends of the rectangle are then stapled to form the annular valve itself.
