초록

A heart valve prosthesis having an annular base carrying two pivoting valving members for use in a heart to control the flow of blood. The valving members are pivotally mounted on the annular base for pivotal movement about separate axes spaced from the center of the base. In one form of the prosthesis the base is removably attached to a suturing assembly adapted to be connected to heart tissue.
